ScriptManager.RegisterStartupScript(this, this.GetType(), "tabmvng", "<script language='javascript'>SetActiveTab(3); </script>", false);

• c#
• javascript
• asp

• It helps a lot if you tell us what is not working, rather than expecting people to guess it. – nunespascal Commented Apr 2, 2013 at 11:45

Try this, It is all because UserControl, you are no longer dealing with a Page.

 ScriptManager.RegisterClientScriptBlock(this.Page, typeof(UpdatePanel), UniqueID, "myFunction('" + parameter + "');", true);

try the following

<script type='text/javascript'>
function SetActiveTab(a){
alert(a);
}
</script>

ScriptManager.RegisterStartupScript(this, this.GetType(), "tabmvng", "SetActiveTab(3);", true);

Control Caller = this; //user control
string MyScript= "SetActiveTab(3);";
ScriptManager.RegisterStartupScript(Caller, typeof(Caller), "Script Name", MyScript), true);

Get through Script manager having trouble adding scripts to the Page object from that user control use a reference to the calling user control. In addition, it will wrap the script for you so no need to add the script tag.

EDIT NOTE: I assume this function exists in your script somewhere: SetActiveTab(3);

ScriptManager.RegisterStartupScript(this.Page, typeof(System.Web.UI.Page), "javascript", "YourScript", true);

I had the same issue of the Javascript not being in the html output. Turns out if you are doing this from ascx (control) you have to pass reference to the control, in example Me.

ScriptManager.RegisterStartupScript(Me, GetType(Page), Guid.NewGuid().ToString(), jscript, True)

After that, all started to work! thanks Mark Schultheiss!
