hi,
I downloaded a source code for a demo available on telerik's website which uses ASP.net AJAX, when I try to run it on my pc it gives me alot of errors, tried to fix them by adding the references again but still errors are coming. The problem is referring to a function in another class is not working. This is a picture of what is happening.

Why the event is not firing?

Hello Telerik Admins and Members,

I have the following problem.

I set EnablePostBackOnRowClick to 'true' I also enable Client-Side row selection and I try the code below

protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
   {
   Label1.Text = "Aa";
   }

in Label1 nothing changes!
When I do the same thing in VB code it works!

Label1.Text = "Aa" is only for test...
I actually need when I click on row (currently selected row) I want the value to be shown in Label. So I guess I have 2 questions!

Barlet,
Thank you

CSS for "all tabs" or "selected tab"

Hi there,
We have been looking in the TabStrip forum is there any way to create a CSS class for the "selected tab" and for "All tabs". We have found in some examples that Telerik have a CSS for "first tab, second tab, etc". Our problem is that we created the tabs on the fly. It depends the number of roles we have in the database.
One way to make this possible would be to create as many tabs in the CSS as we can imagine and it will access to its number but we think this is not the best way to do it.
So our question is:
Is there any CSS class in the control for "All tabs" and one for the "selected tab"?.

Kind regards.

RadTimePicker - Setting Style Client Side

I am attempting to use jQuery to set the background-color style of the RadTimePicker on the client side. While I can set this property using the BackColor attribute on the server side, setting it on the client side never results in visual changes... even though the code executes correctly.

I realize that the input text box in question has a ClientID that differs from the ClientID of the RadTimePicker control. It seems that it always follows the format MyTimePickerClientID_dateInput_text. So in order to change the background color, I do the following:

$(

"#" + <%= this.MyTimePickerControl.ClientID %> + "_dateInput_text").css("background-color", "#FF0000");

This jQuery code seems to run fine, and when I check the background-color in the debugger, it is indeed set to red. Yet there is no visual change in the browser window.

Is what I'm trying to do possible? If so, what am I doing wrong? I have tried this same technique with other style, such as border, but with the same lack of effect.

RadScriptManager unable to load System.Windows

Hello,

In my web application, I have a master page with a RadScriptManager control. I'm getting the following error on page load:

Could not load file or assembly 'System.Windows,Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' orone of its dependencies. The system cannot find the file specified.

Based on the stack trace, the error appears to be thrown from the RadScriptManager constructor:

[FileNotFoundException: Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral,

PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.]

   System.Web.UI.ScriptManager..ctor() +26

   Telerik.Web.UI.RadScriptManager..ctor() +14

The error only occurs the first time I load a page after a build of the application.  As soon as I refresh the page, the error goes away and the application functions as expect.

The error started occurring as soon as I added a Silverlight 3 application in my web app project.

Why are RadScriptManager and the .NET ScriptManager attempting to load a Silverlight dll?  Obviously, this dll is not in the bin directory of the web app.  Any ideas as to how I can make this error go away?

I'm using VS 2010, .NET 4.0, Silverlight 3, and Telerik RadControls for ASP.NET Ajax version 2010.1.415.40.

Thanks,

Andy
