  • User control events not getting to their handlers

    - by PhrkOnLsh
    I am trying to create a user control to wrap around the Membership API (A set of custom Gridviews to display the data better) and, while the code and the controls worked fine in the page, when I moved them to an .ascx, the events stopped firing to it. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomMembership.ascx.cs" Inherits="CCGlink.CustomMembership" %> <asp:Panel ID="mainPnl" runat="server"> <asp:Label id="lblError" ForeColor="Red" Font-Bold="true" runat="server" /> <asp:GridView id="grdUsers" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" OnRowUpdating="grdUsers_RowUpdating" OnRowDeleting="grdUsers_RowDeleting" OnRowCancelingEdit="grdUsers_cancelEdit" autogeneratecolumns="false" allowsorting="true" AllowPaging="true" EmptyDataText="No users..." pagesize="<%# PageSizeForBoth %>" runat="server"> <!-- ...columns... --> </asp:GridView> <asp:Button id="btnAllDetails" onclick="btnAllDetails_clicked" text="Full Info" runat="server" /> <asp:GridView DataKeyNames="UserName" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" id="grdAllDetails" visible="false" allowsorting="true" EmptyDataText="No users in DB." pagesize="<%# PageSizeForBoth %>" runat="server" /> <asp:Button id="btnDoneAllDetails" onclick="btnAllDetails_clicked" text="Done." Visible="false" runat="server" /> </asp:Panel> However, none of the events in the first two controls (the gridview grdUsers and the button btnAllDetails) simply do NOT occur, I have verified this in the debugger. If they occured just fine in the aspx page, why do they die on moving to the ascx? My code in the aspx now is: <div class="admin-right"> <asp:ScriptManager ID="sm1" runat="server" /> <h1>User Management</h1> <div class="admin-right-users"> <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <cm1:CustomMembership id="showUsers" PageSizeForBoth="9" AlternatingRowStylecssclass="alternating" RowStylecssclass="row" DataSource="srcUsers" HeaderStylecssclass="header" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> Thanks.

  • Diagram notation for events

    - by Krt_Malta
    Hi :) I have a part of my program which can be called by various events. Each event however does something different before making use of this part. How can I represent these using a diagram? I was thinking of a flowchart but as far as I know a flow chart can have one start terminal, right? Thanks a lot for the help, Regards, Krt_Malta

  • Multiple key presses doing different events in C#

    - by Nevik Eeirnb
    Hi, private void Form1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.W) player1.moveUp(); if (e.KeyCode == Keys.NumPad8) player2.moveUp(); } In the above code the moveUp methods basically just increment a value. I want it so both keys can be pressed (or held down)at the same time and both events will trigger. Thanks, Nevik

  • Custom Event - invokation list implementation considerations

    - by M.A. Hanin
    I'm looking for some pointers on implementing Custom Events in VB.NET (Visual Studio 2008, .NET 3.5). I know that "regular" (non-custom) Events are actually Delegates, so I was thinking of using Delegates when implementing a Custom Event. On the other hand, Andrew Troelsen's "Pro VB 2008 and the .NET 3.5 Platform" book uses Collection types in all his Custom Events examples, and Microsoft's sample codes match that line of thought. So my question is: what considerations should I have when choosing one design over the other? What are the pros and cons for each design? Which of these resembles the inner-implementation of "regular" events? Below is a sample code demonstrating the two designs. Public Class SomeClass Private _SomeEventListeners As EventHandler Public Custom Event SomeEvent As EventHandler AddHandler(ByVal value As EventHandler) _SomeEventListeners = [Delegate].Combine(_SomeEventListeners, value) End AddHandler RemoveHandler(ByVal value As EventHandler) _SomeEventListeners = [Delegate].Remove(_SomeEventListeners, value) End RemoveHandler RaiseEvent(ByVal sender As Object, ByVal e As System.EventArgs) _SomeEventListeners.Invoke(sender, e) End RaiseEvent End Event Private _OtherEventListeners As New List(Of EventHandler) Public Custom Event OtherEvent As EventHandler AddHandler(ByVal value As EventHandler) _OtherEventListeners.Add(value) End AddHandler RemoveHandler(ByVal value As EventHandler) _OtherEventListeners.Remove(value) End RemoveHandler RaiseEvent(ByVal sender As Object, ByVal e As System.EventArgs) For Each handler In _OtherEventListeners handler(sender, e) Next End RaiseEvent End Event End Class

  • target-action uicontrolevents

    - by Fabrizio Farinelli
    I must be missing something obvious here but ... UIControl has a method - (void)addTarget:(id)target action:(SEL)action forControlEvents: (UIControlEvents)controlEvents which lets you add an action to be called when any of the given controlEvents occur. ControlEvents are a bitmask of events which tell you if a touch went down, or up inside, or was dragged etc., there's about 16 of them, you or them together and get called when any of them occur. The selector can have one of the following signatures - (void)action - (void)action:(id)sender - (void)action:(id)sender forEvent:(UIEvent *) none of those tell you what the control event bitmask was. The UIEvent is something slightly different, it's related to the actual touch event and doesn't (I think) contain the UIControlEvent. The sender (UIControl) doesn't have a way to find the control events either. I'd like to have one method which deals with a number of control events as I have some common code regardless of which event or events happened but I still need to know what the UIControlEvents were for some specific processing. Am I missing a way to find out what UIControlEvents were used when the action was called or do I really have to separate my code into -(void)actionWithUIControlEventX; -(void)actionWithUIControlEventY;

  • How to send Event signal through Processes - C

    - by Jamie Keeling
    Hello all! I have an application consisting of two windows, one communicates to the other and sends it a struct constaining two integers (In this case two rolls of a dice). I will be using events for the following circumstances: Process a sends data to process b, process b displays data Process a closes, in turn closing process b Process b closes a, in turn closing process a I have noticed that if the second process is constantly waiting for the first process to send data then the program will be just sat waiting, which is where the idea of implementing threads on each process occurred and I have started to implement this already. The problem i'm having is that I don't exactly have a lot of experience with threads and events so I'm not sure of the best way to actually implement what I want to do. I'm trying to work out how the other process will know of the event being fired so it can do the tasks it needs to do, I don't understand how one process that is separate from another can tell what the states the events are in especially as it needs to act as soon as the event has changed state. Thanks for any help Edit: I can only use the Create/Set/Open methods for events, sorry for not mentioning it earlier.

  • About global.asax and the events there

    - by eski
    So what i'm trying to understand is the whole global.asax events. I doing a simple counter that records website visits. I am using MSSQL. Basicly i have two ints. totalNumberOfUsers - The total visist from begining. currentNumberOfUsers - Total of users viewing the site at the moment. So the way i understand global.asax events is that every time someone comes to the site "Session_Start" is fired once. So once per user. "Application_Start" is fired only once the first time someone comes to the site. Going with this i have my global.asax file here. <script runat="server"> string connectionstring = ConfigurationManager.ConnectionStrings["ConnectionString1"].ConnectionString; void Application_Start(object sender, EventArgs e) { // Code that runs on application startup Application.Lock(); Application["currentNumberOfUsers"] = 0; Application.UnLock(); string sql = "Select c_hit from v_counter where (id=1)"; SqlConnection connect = new SqlConnection(connectionstring); SqlCommand cmd = new SqlCommand(sql, connect); cmd.Connection.Open(); cmd.ExecuteNonQuery(); SqlDataReader reader = cmd.ExecuteReader(); while (reader.Read()) { Application.Lock(); Application["totalNumberOfUsers"] = reader.GetInt32(0); Application.UnLock(); } reader.Close(); cmd.Connection.Close(); } void Application_End(object sender, EventArgs e) { // Code that runs on application shutdown } void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs } void Session_Start(object sender, EventArgs e) { // Code that runs when a new session is started Application.Lock(); Application["totalNumberOfUsers"] = (int)Application["totalNumberOfUsers"] + 1; Application["currentNumberOfUsers"] = (int)Application["currentNumberOfUsers"] + 1; Application.UnLock(); string sql = "UPDATE v_counter SET c_hit = @hit WHERE c_type = 'totalNumberOfUsers'"; SqlConnection connect = new SqlConnection(connectionstring); SqlCommand cmd = new SqlCommand(sql, connect); SqlParameter hit = new SqlParameter("@hit", SqlDbType.Int); hit.Value = Application["totalNumberOfUsers"]; cmd.Parameters.Add(hit); cmd.Connection.Open(); cmd.ExecuteNonQuery(); cmd.Connection.Close(); } void Session_End(object sender, EventArgs e) { // Code that runs when a session ends. // Note: The Session_End event is raised only when the sessionstate mode // is set to InProc in the Web.config file. If session mode is set to StateServer // or SQLServer, the event is not raised. Application.Lock(); Application["currentNumberOfUsers"] = (int)Application["currentNumberOfUsers"] - 1; Application.UnLock(); } </script> In the page_load i have this protected void Page_Load(object sender, EventArgs e) { l_current.Text = Application["currentNumberOfUsers"].ToString(); l_total.Text = Application["totalNumberOfUsers"].ToString(); } So if i understand this right, every time someone comes to the site both the currentNumberOfUsers and totalNumberOfUsers are incremented with 1. But when the session is over the currentNumberOfUsers is decremented with 1. If i go to the site with 3 types of browsers with the same computer i should have 3 in hits on both counters. Doing this again after hours i should have 3 in current and 6 in total, right ? The way its working right now is the current goes up to 2 and the total is incremented on every postback on IE and Chrome but not on firefox. And one last thing, is this the same thing ? Application["value"] = 0; value = Application["value"] //OR Application.Set("Value", 0); Value = Application.Get("Value");

  • What data to send when tracking clicks with Google Analytics events (and how)?

    - by user359650
    When tracking clicks on links, there are 3 items I'm interested in: link location in the page by grabbing the id of the closest parent: to see influence of location on click-through link text: to see influence of text on click-through link href attribute value: to see where people go when leaving my website The problem when using Google Analytics to track those clicks is that events only have 3 available text fields, one of which being the category, which if you use to store one of the above items will create a mess in your Event reporting because you will have as many categories as item values. Therefore if you assign a predefined value to the category (e.g. clicks), then you're left with only 2 event fields (action, label) to store 3 items (location, text, href). That in itself isn't the end of the world because you can concatenate 2 items into 1 event field, then use the reporting or the API to filter things out. Accordingly what I plan on doing is this: category: clicks action: {location_on_page} ¦ {text} label: {href} where {__} are variable values related to the clicked links With this I can easily create some reports directly via the GUI: downloads: include only events where label ends with .pdf click outs to particular domains: include only events where label contains domain And for more complex tasks I need to export the data (or use the API): influence of location on clicks: for each location in the design, count number of events that have that location in the action, then corroborate with pageviews of the corresponding pages. Whilst this looks good I'm wondering if there is a better approach, hence the following questions: Q1: Can you foresee any particular issues with this particular setup (e.g. things I won't be able to report on)? Q2: Can you think of other data that would be interesting to include in the event?

  • jQuery: How to check if a value exists in an array?

    - by Jannis
    Hello, I am trying to write a simple input field validation plugin at the moment (more of a learning exercise really) and thought this would not be too hard, seeing as all I should have to do is: Get input fields Store them in array with each one's value On submit of form check if array contains any empty strings But I seem to fail at writing something that checks for an empty string (read: input with no text inside) inside my array. Here is the code I have so far: var form = $(this), // passed in form element inputs = form.find('input'), // all of this forms input fields isValid = false; // initially set the form to not be valid function validate() { var fields = inputs.serializeArray(); // make an array out of input fields // start -- this does not work for (var n in fields) { if (fields[n].value == "") { isValid = false; console.log('failed'); } else { isValid = true; console.log('passed'); }; } // end -- this does not work }; // close validate() // TRIGGERS inputs.live('keyup blur', function(event) { validate(); }); Any help with how I can check if one of the fields is blank and if so return a isValid = false would be much appreciated. I also played around with the $.inArray("", fields) but this would never return 0 or 1 even when the console.log showed that the fields had no value. Thanks for reading.

  • Jquery JQGrid - How to set alignment of grid header cells?

    - by JK
    Is it possible to align grid column headers in jqgrid? eg align left right or center? In the jqrid documents http://www.trirand.com/jqgridwiki/doku.php?id=wiki:colmodel_options it says: align: Defines the alignment of the cell in the Body layer, not in header cell. Possible values: left, center, right. Note that it says "not in the header cell". How can I do this for the header cell (grid title cell)? The documentation fails to mention this little detail....

  • Is there a 'has focus' in JavaScript (or jQuery)?

    - by alex
    Is there something I can do like this (perhap via a plugin) if ( ! $('form#contact input]').hasFocus()) { $('form#contact input:first]').focus(); } Basically, set focus to the first input, but only if the user has not already clicked into anything? I know this will work too, but is there anything more elegant? $(function() { var focused = FALSE: $('form#contact input]').focus(function() { focused = TRUE; }); setTimeout(function() { if ( ! focused) { $('form#contact input:first]').focus(); }; }, 500); });

  • How to use jQuery datepicker as a control parameter for SqlDataSource?

    - by Matt
    I have the need to display a date in this format: dd/mm/yyyy. This is actually being stored in an ASP.NET textbox and being used as a control parameter for a select on the GridView. When the query is run, though, the date format should change to 'd M y' (for Oracle). It is not working. Can someone tell me what I'm doing wrong? Right now I am pushing the "new" format to a invisible label and using the label as my control param: $(document).ready(function() { //datepicker for query, shown traditionally but holding an Oracle-needed format $('[id$=txtBeginDate]').datepicker({ minDate: -7 , altFormat: 'd M y' }); //get alt format var altFormat = $('[id$=txtBeginDate]').datepicker("option", "altFormat"); //set date to be altformat $('[id$=lblActualDate]').datepicker("option", "altFormat", 'd M y'); });

  • DHTMLX Calendar onChange

    - by Sickaaron
    I am having an issue with the DHTMLX Calendar with the onChange in the input field. I am initialisating the code with the following: jQuery(document).ready(function($){ var calendar; calendar = new dhtmlXCalendarObject(["date"]); calendar.hideTime(); calendar.setDateFormat("%d/%m/%Y"); $('.lightbox').lightbox(); $('#slider').cycle(); }); function checkDate() { var date = $("[name='date']").val(); alert(date); } In the form i am using: <input type="text" name="date" id="date" onchange="checkDate();" /> How it should be (and was working with JQuery UI datepicker) once the date is entered into the input field the onchange function would fire. However in this case: the onchange with this calendar does nothing. I have tried changing the following to this: jQuery(document).ready(function($){ var calendar; calendar = new dhtmlXCalendarObject(["date"]); calendar.hideTime(); calendar.setDateFormat("%d/%m/%Y"); calendar.attachEvent("onChange",function(date, state){ checkDate(); }); $('.lightbox').lightbox(); $('#slider').cycle(); }); function checkDate() { var date = $("[name='date']").val(); alert(date); } But the onchange event happens before the date is entered, ie when i click on the input field. Reason for changing from JQuery UI to this DHTMLX is that JQuery UI Datepicker does not support all platforms (iPhones/iPads etc) and DHTMLX does.

  • jqGrid disable sortablerows

    - by gurun8
    I'm trying to disable sortablerows functionality from a grid. I'd like to have the ability to toggle on/off the sortablerows functionality. Enabling the feature is pretty straightforward: jQuery("#list").jqGrid('sortableRows', { update: function(event, ui) { updateOrder() } }); But disabling the feature has proven to be a little bit harder. I've consulted the UI Integrations where sortableRows is documented in the jqGrid Wiki: www.trirand.com/jqgridwiki/doku.php?id=wiki:jquery_ui_methods And found that "The method is fully compatible with jQuery UI sortable widget." So I ventured off to the jQuery UI sortable documentation and found this: http://jqueryui.com/demos/sortable/ jQuery("#list").jqGrid('sortableRows', {disabled: true}); The code above simply disables the rows. So I moved onto the destroy method: jQuery("#list").jqGrid('sortableRows', {destroy: true}); but that doesn't do anything. Based upon the documentation the destroy method seems to be exactly what I need, so maybe my syntax is wrong but I can't seem to get it to work. Does anyone have experience with this same issue?

  • reinitialize jqTransform?

    - by SoulieBaby
    Hi all, I'm using jqTransform to make my forms look a bit prettier, however I'm using jquery to change the select list (depending on what's selected from another select list) and it just pulls in the regular form select list rather than the jqTransform styles.. I was wondering if there's a way of reinitializing it? I've tried adding: jQuery('#bookingForm').jqTransform({ imgPath: '/templates/home/images/jqtransform/' }); after the jquery inserts the new select box, but it doesnt seem to work.. I'm trying to do this because I couldnt figure out how to show/hide options in a select list using jquery.
