I do try to use the modalpopup extender, it works with the client button click but not with the server side method.
I even used the document.readyState == "complete" javascript method to be shure the whole page is loaded.

Im not able to find control in datalist.

I have downloaded the ajax toolkit control i been using it for a couple of months now. But I cannot see Ajax toolkit pie chart control..
Why will I get it ? Do I have to download seperately?
I am able to find the controls of all of these Lables and TextBoxes accept the edateTB. This is strange to me because it is in the same view as the sdateTB. So why would edateTB return NULL when I try to use FindControl on it and sdateTB return the correct control?
Here is the codebehind where I am getting this error. There is more code in this, but I just thought I would include everything up to the part where I get the NULL error.

View 5 RepliesWhen I use Project Reference to add dependent assemblies to my C# library project, I can use the "Go To Definition" popup menu item to go to the source file of the class defined in the dependent assembly. That is one of the most useful features of VS for me. However, when I add dependent assemblies as BIN References (via the Browse tab of the Add Reference dialog), I only get the class definition generated from metadata of the dependenat assembly, not the source file.
I realize that intellisense can't find the source directory of the dependent assembly, but where can I enter the directories so intellisense would know? There is a "VC++ Directories" page in the Options->Projects and Solutions dialog, but that is only for C/C++ projects. There should be one for C# as well. The bigger mystery is when I put my project in the debugger, I can step into methods defined in the dependent assembly and see its source file. Why could the debugger find the source file but not intellisense?
I'm trying to define the parameters of my data source using a stored procedure. My Stored Procedure Syntax is perfect and i'm happy with that, i've just got trouble with connecting my parameters to my controls. I have 19 Parameters, of which i've managed to connect 17 to controls within my ASP.Net form (some to text boxes, some to ddls etc...)
However, i'm trying to connect a particular parameter to a control, but when i drop down my list of controls it's not visible? The control is within a hidden panel so i've un-hidden it and it's still not there. I've even commented out the panel and tried that but i can't find this control! I just cant seem to get this control to appear in the list.
Has any one seen anything like this before at all?

This has got me stumped. I am trying to find a checkbox in a dynamically loaded asp.net Repeater template. The template works fine and the databinding is fine and everything displays fine but I can't find the control!
This is the repeater code (I have a similar one for the alternate template with a different style):

I am working on a page where I am looking a relationship property of Treeview.
TreeView1.Nodes.Add Relative, Relationship, Key, Text, Image, SelectedImage
Can We set Relationship here like tvwNExt, tvWFirst like vb. I am unable to find in ASP.NET I have a requirement where I need to go through in loop and set the parent Node, once and then child node. But due to loop its add parent node value everytime.
I have a web page, I am adding treenode value from database. I need to check if any value is already added in node then childnode value should be added in the same parent node. In vb6.0 we have something Key of the node, but here I am unable to find. Here we get only text and Value for any Node.
View 2 RepliesI have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.
Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.
The code behind for the user control executes as expected, but any reference to child controls are null.
It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.
i am trying to bind data to a datagridview control on an ASPX webpage and am using something like this..
<asp:TemplateField HeaderText="MyField">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "MyField") %>
</ItemTemplate>
</asp:TemplateField>
the problem i am having is that the data for the 'MyField' field is actually an integer that is a reference to a string value in another sql table.
Does anyone know how i can reformat my code line above to show the string value instead of the int value?

I'm trying to load web resources from a linked assembly. Whatever I try, I get the exception:
Web resource 'MyNameSpace.scripts.jquery-min.js' was not found.
I'm using the following code to load it:
ScriptManager.RegisterClientScriptResource(this, typeof(MyNameSpace.SomeClass), "MyNameSpace.scripts.jquery-min.js");
What am I missing / doing wrong here, causing that exception?
My observations so far:
In the Reflector these resource is visible, and named as MyNameSpace.scripts.jquery-min.js In the AssemblyInfo.cs file of the project, the file is registered as:
[assembly: WebResource("scripts/jquery-min.js", "text/javascript")]
The file lives in the 'scripts' directory
On a sidenote, I've tried using Page.ClientScript.GetWebResourceUrl() but this generates an URL without checking if the resource exists. It also seems WebResource.axd is not mapped in Web.config at all.
