Try this code     ScriptManager RegisterClientScriptBlock UpdatePanel1  this GetType     script    alert  Hi      true     Where UpdatePanel1 is the id for Updatepanel on your page

You must put the updatepanel id in the first argument if the control causing the script is inside the updatepanel else use the keyword  this  instead of update panel here is the code   ScriptManager RegisterStartupScript UpdatePanel3  this GetType    UpdatePanel3 UniqueID   showError      true

Off the top of my head     Use GetType   instead of typeof Page  in order to bind the script to your actual page class instead of the base class  Pass a key constant instead of Page UniqueID  which is not that meaningful since it s supposed to be used by named controls  End your Javascript statement with a semicolon  Register the script during the PreRender phase      protected void Page PreRender object sender  EventArgs e        ScriptManager RegisterStartupScript this  GetType     YourUniqueScriptKey             alert  This pops up      true

I came across a similar issue  However this issue was caused because of the way i designed the pages to bring the requests in  I placed all of my  js files as the last thing to be applied to the page  therefore they are at the end of my document  The  js files have all my functions include  The script manager seems that to be able to call this function it needs the js file already present with the function being called at the time of load  Hope this helps anyone else
