  • Calling ASP.NET MVC Controller explicitly via AJAX

    - by effkay
    I know that I can use following piece of code to refresh a div: <%=Ajax.ActionLink( "Update", "Administration", new AjaxOptions { UpdateTargetId = "grid", LoadingElementId = "grid-wait" } ) %> But this creates a link; user will have to click on it to get the view refreshed. How can I make it automatic, i.e., like say if I want the grid to be refreshed after every five seconds?

  • ASP.NET MVC: Html.Actionlink() generates empty link.

    - by wh0emPah
    Okay i'm experiencing some problems with the actionlink htmlhelper. I have some complicated routing as follows: routes.MapRoute("Groep_Dashboard_Route", // Route name "{EventName}/{GroupID}/Dashboard", // url with Paramters new {controller = "Group", action="Dashboard"}); routes.MapRoute("Event_Groep_Route", // Route name "{EventName}/{GroupID}/{controller}/{action}/{id}", new {controller = "Home", action = "Index"}); My problem is generating action links that match these patterns. The eventname parameter is really just for having a user friendly link. it doesn't do anything. Now when i'm trying for example to generate a link. that shows the dashboard of a certain groep. Like: mysite.com/testevent/20/Dashboard I'll use the following actionlink: <%: Html.ActionLink("Show dashboard", "Group", "Dashboard", new { EventName_Url = "test", GroepID = item.groepID}, null)%> What my actual result in html gives is: <a href="">Show Dashboard</a> Please bear with me i'm still new at ASP MVC. Could someone tell me what i'm doing wrong? Help would be appreciated!

  • ASP.NET MVC 2 RC2 Model Binding with NVARCHAR NOT NULL column

    - by Gary McGill
    I have a database column defined as NVARCHAR(1000) NOT NULL DEFAULT(N'') - in other words, a non-nullable text column with a default value of blank. I have a model class generated by the Linq-to-SQL Classes designer, which correctly identifies the property as not nullable. I have a TextAreaFor in my view for that property. I'm using UpdateModel in my controller to fetch the value from the form and populate the model object. If I view the web page and leave the text area blank, UpdateModel insists on setting the property to NULL instead of empty string. (Even if I set the value to blank in code prior to calling UpdateModel, it still overwrites that with NULL). Which, of course, causes the subsequent database update to fail. I could check all such properties for NULL after calling UpdateModel, but that seems ridiculous - surely there must be a better way? Please don't tell me I need a custom model binder for such a simple scenario...!

  • Validate a single property with the Fluent Validation Library for .Net

    - by Blegger
    Can you validate just a single property with the Fluent Validation Library, and if so how? I thought this discussion thread from January of 2009 showed me how to do it via the following syntax: validator.Validate(new Person(), x => x.Surname); Unfortunately it doesn't appear this works in the current version of the library. One other thing that led me to believe that validating a single property might be possible is the following quote from Jeremy Skinners' blog post: "Finally, I added the ability to be able to execute some of FluentValidation’s Property Validators without needing to validate the entire object. This means it is now possible to stop the default “A value was required” message from being added to ModelState. " However I do not know if that necessarily means it supports just validating a single property or the fact that you can tell the validation library to stop validating after the first validation error.

  • Why did the aspnet_client folder come back in ASP.NET 4?

    - by rbeier
    I recently upgraded my MVC 1 project (ASP.NET 3.5) to MVC 2 (ASP.NET 4). I noticed there is now a folder "aspnet_client\system_web\4_0_30319" under the site root. This folder is empty... I'm just wondering if anyone knows why it was created. I remember the aspnet_client folder from the days of .NET 1.1, but I thought it was obsoleted when .NET 2.0 came out. For example, see the answers in these two stackoverflow posts: What is the aspnet_client folder in my ASP.NET website? What is the aspnet_client folder for under the IIS structure? So I'm just curious why it's back. Thanks, Richard

  • Calling a generic function in VB.NET / C#

    - by Quandary
    Question: I want to call a generic function, defined as: Public Shared Function DeserializeFromXML(Of T)(Optional ByRef strFileNameAndPath As String = Nothing) As T Now when I call it, I wanted to do it with any of the variants below: Dim x As New XMLserialization.cConfiguration x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of x)() x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(GetType(x))() x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of GetType(x))() But it doesn't work. I find it very annoying and unreadable having to type x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of XMLserialization.cConfiguration)() Is there a way to call a generic function by getting the type from the instance ?

  • Help with editing data in entity framework.

    - by Levelbit
    Title of this question is simple because there is no an easy explanation for what I'm trying to ask you. I hope you'll understand in the end :). I have to tables in my database: Company and Location (relationship:one to many) and corresponding entity sets. In my wpf application I have some datagrid which I want to fill with locations and to be able to edit every row in separate window as some form of details view (so I don't want to edit my data in datagrid). I did this by accessing Location entity from selected row and creating a new Location entity and then I copy properties from original entity to newly created. Something like cloning the object. After editing if I press OK changed data is copied to original object back, and if I press Cancel nothing happens. Of course, you probably thinking I could use NoTracking option and AttachAsModified method as was mentioned as solution in some earlier questions(see:http://stackoverflow.com/questions/803022/changing-entities-in-the-entityframework) by Alex James, but lets say I had some problems about that and I have my own reasons for doing this. Finally, because navigation property(Company) of my location entity is assigned to newly created location object(during cloning) from some reason in object context additional object as copy of object I want to edit from datagrid is created without my will(similar problem :http://blogs.msdn.com/alexj/archive/2009/12/02/tip-47-how-fix-up-can-make-it-hard-to-change-relationships.aspx). So, when I do ObjectContext.SaveChanges it inserts additional row of data into my database table Location, the same as the one i wanted to edit. I read about sth like this, but I don't quite understand why is that and how to block or override this. I hope I was clear as I could. Please, solutions or some other ideas.

  • Should the entity framework + self tracking entities be saving me time

    - by sipwiz
    I've been using the entity framework in combination with the self tracking entity code generation templates for my latest silverlight to WCF application. It's the first time I've used the entity framework in a real project and my hope was that I would save myself a lot of time and effort by being able to automatically update the whole data access layer of my project when my database schema changed. Happily I've found that to be the case, updating my database schema by adding a new table, changing column names, adding new columns etc. etc. can be propagated to my business object classes by using the update from database option on the entity framework model. Where I'm hurting is the CRUD operations within my WCF service in response to actions on my Silverlight client. I use the same self tracking entity framework business objects in my Silverlight app but I find I'm continually having to fight against problems such as foreign key associations not being handled correctly when updating an object or the change tracker getting confused about the state of an object at the Silverlight end and the data access operation within the WCF layer throwing a wobbly. It's got to a point where I have now spent more time dealing with this quirks than I have on my previous project where I used Linq-to-SQL as the starting point for rolling my own business objects. Is it just me being hopeless or is the self tracking entities approach something that should be avoided until it's more mature?

  • why can't asp.net find my textbox?

    - by phunehehe
    Hello, I'm trying to add more fields to the CreateUserWizardStep, here is what I added: <asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server"> <ContentTemplate> <table border="0"> <tr> <td align="right"> <asp:Label ID="NickNameLabel" runat="server" AssociatedControlID="NickName">Nick Name:</asp:Label> </td> <td> <asp:TextBox ID="NickName" runat="server"></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="NickName" ErrorMessage="Nick Name is required." ToolTip="Nick Name is required." ValidationGroup="CreateUserWizard1">*</asp:RequiredFieldValidator> </td> </tr> <%-- The default code is left unchanged, but not shown here --%> </table> </ContentTemplate> </asp:CreateUserWizardStep> Then I tried to reference the objects like this protected void NewUserWizard_CreatedUser(object sender, EventArgs e) { CreateUserWizardStep step = NewUserWizard.FindControl("CreateUserWizardStep1") as CreateUserWizardStep; TextBox nickName= step.FindControl("NickName") as TextBox; // insert additional information to the database } The problem is, I'm getting nulls for nickName. Am I using FindControl("") incorrectly?

  • Bind ISet in ASP.NET MVC2

    - by Dmitriy Nagirnyak
    Hi, I am trying to find out what would be the best bind first element of ISet (Iesi.Collection) as a first element. So basically I only have to use some kind of collection that has an indexer (and ISet doesn't) then I can write code like this (which works perfectly well): <%: Html.EditorFor(x => x.Company.PrimaryUsers[0].Email) %> But as the ISet has no indexer I cannot use it. So how can I then bind the first element of ISet in MVC2? Thanks, Dmitriy.

  • Read assembly Guid without locking the DLL in an appdomain in medium trust ASP.Net

    - by ggonsalv
    Is it possible to read the GUID from the Assembly without actually loading it in the current App Domain. Normally Assembly.Load loads the DLL into the app domain. I just want to read the value. The description of the GUID is 'The following GUID is for the ID of the typelib ' if this project is exposed to COM <Assembly: Guid("DEDDE61CD-928E-4ACD-8C25-3B8577284819")> The main thing is I don't want to lock the file so that there are no errors 'Another process is accessing the file' error.

  • problem with RenderOuterTable property for .net 4.0 controls

    - by Mario
    According to the new 4.0 framework overview, one should be able to add the attrib RenderOuterTable="false" to a control that supports the attribute and see css friendly code be spit out - in other words no html tables. To test this, I threw a login control into a basic fresh webpage with the following code: <asp:Login ID="Login1" runat="server" RenderOuterTable="false"></asp:Login> The result? Crappy html table output, which supposedly doesn't happen with this attrib set to false. Here is the output: &lt;table cellpadding=&quot;0&quot;&gt; <tr> <td align="center" colspan="2">Log In</td> </tr><tr> <td align="right"><label for="MainContent_Login1_UserName">User Name:</label></td><td><input name="ctl00$MainContent$Login1$UserName" type="text" id="MainContent_Login1_UserName" /><span id="MainContent_Login1_UserNameRequired" title="User Name is required." style="visibility:hidden;">*</span></td>... Hopefully you get the point. Anyone know how to stop these controls from outputting tables? This is super annoying.

  • Working with images in asp.net MVC ViewMasterPage in design mode

    - by amit.codename13
    While designing a master page i am adding a number of images to it. I have an image tag inside the master page, <img src="../../Content/Images/img19.jpg" class="profileImage" /> When i run my app, the image doesn't show up in the browser because the src path in the page that browser gets is same as in the master page. ie. "../../Content/Images/img19.jpg" But it should have been "Content/Images/img19.jpg" If i correct the src path in master page as <img src="Content/Images/img19.jpg" class="profileImage" /> Then I can see the image in the browser but not in design mode. Any help is appreciated.

    I have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'. When the button is clicked code similar to the following is executed: If FileUploadControl.HasFile Then 'Save the file and do some other stuff End If This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?! Any suggestions/ideas would be greatly appreciated.

  • Entity Framework - avoiding another query

    - by adamjellyit
    I have a requirement to only save data to a table in a database (I don't need to read it) If the record already exists I want to update it otherwise I will add it. It usually exists. My entity context might already hold the object .. if it does I want to find it and use it again without causing it to refresh from the database when I 'find' it i.e. The context holds a collection of entities (rows of a database) I want to find an entity in the collection and only want the context to go to the database if entity is not in the collection. I don't care about the current values of the entity .. I just want to update them. Hope this is clear ..... thanks
