My website needs to output some dynamically generated Javascript but it doesn't run when I AJAX up my controls. I assume because the script element is not connected to the AJAX Manager/Panel.

So I added a RadScriptBlock but I can't for the life of me find out how to add the script to it from the c# server side.

Is this possible?

The last thing I tried was this (but Text is obviously not right),

LiteralControl script = (LiteralControl)radScriptBlock.Controls[0];  
script.Text = "UpdateMainWindow('" + Session["IdM_btnUpdate_ClientID"].ToString() + "');";

OK, I figured this out (but still have a problem).

The following adds the script to the RadScriptBlock and it works fine unless I try and AJAX up my page.

LiteralControl script = new LiteralControl("<script type=\"text/javascript\" language=\"javascript\">ShowSiteLASelector('" + Session["IdM_radMenuContext_ClientID"].ToString() + "');</script>");  
radScriptBlock.Controls.Clear();  
radScriptBlock.Controls.Add(script); 

The problem I still have is that when my RadScriptBlock is put within a RadAjaxPanel then the javascript fails to execute. Any idea why...?

Hi ADe,

Do you add the script to the RadScriptBlock control programmatically each time the PageLoad handler of the page is executed? You may also directly modify the LiteralControl nested in the RadScriptBlock instance as follows:

String scriptContent = "script type=\"text/javascript\" language=\"javascript\">ShowSiteLASelector('" + Session["IdM_radMenuContext_ClientID"].ToString() + "');</script>";     
(radScriptBlock.Controls[0] as LiteralControl).Text = scriptContent;
