  • How can I programmatically add triggers to an ASP.NET UpdatePanel?

    - by scottm
    I am trying to write a quote generator. For each product, there are a set of options. I want to dynamically add a drop down list for each option, and then have their SelectedIndexChanged events all wired up to update the quote cost. I am not having any trouble adding the DropDownList controls to my UpdatePanel, but I can't seem to wire up the events. After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this: QuotePanel.ASCX <asp:ScriptManager ID="ScriptManager" runat="server" /> <asp:UpdatePanel ID="QuoteUpdatePanel" runat="server" ChildrenAsTriggers="true"> <ContentTemplate> Cost: <asp:Label ID="QuoteCostLabel" runat="server" /> <fieldset id="standard-options"> <legend>Standard Options</legend> <asp:UpdatePanel ID="StandardOptionsUpdatePanel" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional"> <ContentTemplate> </ContentTemplate> </asp:UpdatePanel> </fieldset> </ContentTemplate> </asp:UpdatePanel> The code to add the dropdowns and the event they are to be wire up for: protected void PopluateUpdatePanel(IQuoteProperty standardOptions) foreach (IQuoteProperty standardOp in standardOptions) { QuotePropertyDropDownList<IQuoteProperty> dropDownList = new QuotePropertyDropDownList<IQuoteProperty>(standardOp); dropDownList.SelectedIndexChanged += new EventHandler(QuotePropertyDropDown_SelectedIndexChanged); dropDownList.ID = standardOp.GetType().Name + "DropDownList"; ScriptManager.RegisterAsyncPostBackControl(dropDownList); Label propertyLabel = new Label() {Text = standardOp.Title, CssClass = "quote-property-label"}; this.StandardOptionsUpdatePanel.ContentTemplateContainer.Controls.Add(propertyLabel); this.StandardOptionsUpdatePanel.ContentTemplateContainer.Controls.Add(dropDownList); _standardOptionsListBoxes.Add(dropDownList); AsyncPostBackTrigger trigger = new AsyncPostBackTrigger() { ControlID = dropDownList.UniqueID, EventName = "SelectedIndexChanged" }; this.StandardOptionsUpdatePanel.Triggers.Add(trigger); } } void QuotePropertyDropDown_SelectedIndexChanged(object sender, EventArgs e) { QuoteCostLabel.Text = QuoteCost.ToString(); }

  • .NET and C# Exceptions. What is it reasonable to catch.

    - by djna
    Disclaimer, I'm from a Java background. I don't do much C#. There's a great deal of transfer between the two worlds, but of course there are differences and one is in the way Exceptions tend to be thought about. I recently answered a C# question suggesting that under some circstances it's reasonable to do this: try { some work } catch (Exeption e) { commonExceptionHandler(); } (The reasons why are immaterial). I got a response that I don't quite understand: until .NET 4.0, it's very bad to catch Exception. It means you catch various low-level fatal errors and so disguise bugs. It also means that in the event of some kind of corruption that triggers such an exception, any open finally blocks on the stack will be executed, so even if the callExceptionReporter fuunction tries to log and quit, it may not even get to that point (the finally blocks may throw again, or cause more corruption, or delete something important from the disk or database). May I'm more confused than I realise, but I don't agree with some of that. Please would other folks comment. I understand that there are many low level Exceptions we don't want to swallow. My commonExceptionHandler() function could reasonably rethrow those. This seems consistent with this answer to a related question. Which does say "Depending on your context it can be acceptable to use catch(...), providing the exception is re-thrown." So I conclude using catch (Exception ) is not always evil, silently swallowing certain exceptions is. The phrase "Until .NET 4 it is very bad to Catch Exception" What changes in .NET 4? IS this a reference to AggregateException, which may give us some new things to do with exceptions we catch, but I don't think changes the fundamental "don't swallow" rule. The next phrase really bothers be. Can this be right? It also means that in the event of some kind of corruption that triggers such an exception, any open finally blocks on the stack will be executed (the finally blocks may throw again, or cause more corruption, or delete something important from the disk or database) My understanding is that if some low level code had lowLevelMethod() { try { lowestLevelMethod(); } finally { some really important stuff } } and in my code I call lowLevel(); try { lowLevel() } catch (Exception e) { exception handling and maybe rethrowing } Whether or not I catch Exception this has no effect whatever on the excution of the finally block. By the time we leave lowLevelMethod() the finally has already run. If the finally is going to do any of the bad things, such as corrupt my disk, then it will do so. My catching the Exception made no difference. If It reaches my Exception block I need to do the right thing, but I can't be the cause of dmis-executing finallys

  • API for displaying graphs in a web app?

    - by Rosarch
    I have graphs (nodes/arcs) that I want to display to the user. I need to be able to capture the event of a user clicking on a node. Something like Google Charts API's Simple Org Chart would be great, but it looks like it only supports trees. What other service can I use? Or should I hack something ugly together using Google Charts?

  • Resizing qt widgets when their children are hidden

    - by laura
    I have the situation in the following image: How would I go about resizing the widget when the retry child is hidden so that it looks as in the first image? The main layout is a QVBoxLayout, the retry child is a widget with a QVBoxLayout as well. I've tried the following: update() updateGeometry() setGeometry(childrenRect()) layout()-activate() on the main widget as soon as I've set the retry widget to hidden. Do I need to intercept some event to do this?

  • mootools fx working except in ie9

    - by Craig
    This is my first attempt with Mootools, so I welcome a critique of the code. I have a dynamic list of images that expand on the 'click" event and contract on the 'mouseout' event. The code works fine in all browsers (FF, Safari, Chrome, even the smartphones) but not in IE9 (JS is enabled) Anyone with similar problem or solution? I plan to use a lightbox effect, downloading a larger & clearer image to the center of the page, instead of just resizing a small image. However, I am hesitant to attempt this, if there is problems with IE9. I have coded three image sizes with the upload commit, so the larger image is available for the lightbox, but, I don't see anything in mootools for a lightbox, or am I missing it? $i = 0; while($i < count($validate)) { <div class="validate"> <div class="validate_image_<?php echo $validate[$i]['validate_type']; ?>"> <div class="validate_image" id="validate_image_wrapper_<?php echo $i; ?>"> <?php if ($validate[$i]['validate_image_filename'] != '') { if (file_exists(UPLOAD_DIR . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']))) { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']) . '" alt="Listing Image" />'; } else { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_large.', $validate[$i]['validate_image_filename']) . '" alt="Listing image" />'; } } else { ?> <img src="/images/no_image_posted_validate.png" alt="no image posted" /> <?php } ?> </div> ... remainder of HTML display code function setupEnlargeImage() { window.myFx = new Fx({ duration: 200, transition: Fx.Transitions.Sine.easeOut }); $$('.validate_image').addEvent('click', function() { window.selectedImage = this.id; myFx.start(1,2.0); }); $$('.validate_image').addEvent('mouseout', function() { window.selectedImage = this.id; myFx.start(1.0,1); }); myFx.set = function(value) { var style = "scale(" + (value) + ")"; $(window.selectedImage).setStyles({ "-webkit-transform": style, "-moz-transform": style, "-o-transform": style, "-ms-transform": style, transform: style }); } }

  • Is it possible to detect the load of an applet?

    - by zneak
    Hello guys, I'm working on a Safari extension, and I'd like to detect when <applet>s load on a page. However, there seems to be no onload event for these. How should I do it? Transform all <applet> tags to <object> tags and then intercept their onload events? Is there a better way?

  • Getting events out of Facebook?

    - by RD
    Is it possible to get event info from Facebook so the following is true: Add events that are not just your own events (i.e. search for general events and not just grab the events you have set as attended by your user) Specify criteria (e.g. get all events for one specific city) If this is possible, what should one use? where do you start?

  • ToolStripMenuItems and Drag and Drop

    - by Paul
    I need to implement "Drag and Drop" operations for the ToolStripMenuItems. Everything works fine only with ToolStripMenuItems on the first level. I mean I can't move menu item from a submenu to other one. But I can move submenu to top-level menu. I noticed that DragEnter event isn't arise for submenus. Initialization is the same for all menu-items. What is wrong? :(
