AJAX :: How To Register A Programmatically Inserted UserControl As A Trigger

Mar 22, 2010

I have a page that dynamically inserts user controls into a placeholder depending on values in a database table. The user controls consist of a label and one control (dropdownlist, radiobuttonlist, or checkbox). The controls will also have the AutoPostBack property set programmitcally depending on values in the database. My update panel is on the main page, not in the user control. I have tried the ScriptManager.RegisterPostBackControl method to register the UserControl on page load, but the page still does a post back. I think I need to register the control that is inside the UserControl, but I have no idea how to access it from the main page_load event.

This thread is the closest to what I am trying to do, but since I am inserting the user controls programmatically, I need the triggers to be registered programmatically as well. Also, I need to register
them as PostBackTrigger instead of AsyncPostBackTrigger because I need to do a full page reload because the user controls are inserted dynamically.

AJAX :: How To Programmatically Trigger An Event Handler

Mar 2, 2010

I need to run a SELECT box [on]change handler after changing the selectedIndex.

I see the selectBox._events['change'][0].handler() method added by $addHandler, but what is the ASP.NET Ajax way to raise it as an event?

The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.

Web Forms :: Register JavaScript In UserControl

Mar 1, 2011

I have a UserControl, ASPX page, a Class file and a JS file. In Class file, I have a method for building and registering textbox controls:

ScriptManager.RegisterClientScriptBlock(this,
typeof(Page),
"onfocus", jsText.ToString(),
true);

jsText is nothing but Name and Value pair strings. Example : "KEY1:txtName, KEY2:txtDOB" In UserControl, I am calling the above Class method to pass all the textboxes and calling the JS file to validate the registered controls. Then, I am calling that Usercontrol in ASPX page. Here I am unable to validate the controls as it is saying "KEY is undefined".

ADO.NET :: How To Trigger LinqDataSource Programmatically

Mar 16, 2011

how to trigger the Select() method.

Here's the scenario: ASP.NET 3.5 C# app connecting to an MS SQL backend. I created a LINQ to SQL class called test.dbml and dragged a table called tblTest to the design surface. The table has two columns: the primary key is Email and the other column is Name. Then I dropped a LinqDataSource on the page. The LinqDataSource is not connected to a databound control. It will only being used to retrieve the name associated with a supplied email address. In the Page_Load event, I feed the Where clause:

[Code]....

However, I put a breakpoint inside the ldsAdmin_Selected event and it never hits. With an ObjectDataSource, you can use odsAdmin.Select(); to trigger the ObjectDataSource to actually run and return the info. What's the equivalent method of triggering a LinqDataSource?

Create A Usercontrol Instance Programmatically?

Feb 16, 2011

I have a UserControl that I need to add dynamically. I tried to follow this MSDN article, but I'm not having any success....[URL]

The UserControl is basically an image gallery, and it loads some pictures based on an ID. My idea was to make this ID available as a property. Then when I create an instance of the control, I could set this ID and add it to the form.

I added a reference to the control in the .aspx page that will use it, like this:

<%@ Reference Control="~/PictureGallery.ascx" %>

And in the UserControl I added a ClassName like this:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PictureGallery.ascx.cs"
Inherits="PictureGallery" ClassName="PictureGallery" %>

When I try to create an instance in the .aspx.cs like the article suggests, Dim gallery As ASP.PictureGallery, I get an "Type ASP.PictureGallery is not defined".

The article mentions a namespace, ASP, and I tried importing it to the .aspx.cs with no luck. So, I'm not able to get a reference to the UserControl.

Register AJAX Tagprefix In Web.config?

Dec 27, 2010

I'm learning ajax and have created some pages and practiced using the ajax controls. I’m using visual studio 2007 on a windows xp machine with .net 3.5 . The site I’m practicing with is the ajax sample web site that I’ve downloaded. I’m just adding pages to this site as practice. Using a tag prefix of ajaxToolkit

Code:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
I have read serveral sites that you can register the assembly and the tag prefix by placing code in the web config, so Between the assemblies Tags of the we congif I entered

Code:

<add assembly="AjaxControlToolkit, Version=3.5.40412.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>
And between the <controls> tag the web config I added

Code:

<add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit, Version=3.5.40412.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>
This didn’t work because when an ajax control is added from the toolbox get asp tag

Code:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:ComboBox ID="ComboBox1" runat="server">
</asp:ComboBox>
