        //Java script to open the window for Billboard preview
        if (ClientScript != null)
            if (!ClientScript.IsStartupScriptRegistered("Startup"))

                scriptString = "<script language=javascript>";
                scriptString = string.Format("{0} window.open('page1.aspx?ID=' + document.frm1.hidID.value, '_blank', 'width=300, height=430, location=no, menubar=no, resizable=no, scrollbars=no, status=no, titlebar=no, toolbar=no', 'true');", scriptString);

Hello Venkatesh,

You need to use the static methods of the ScriptManager to register client-side scripts. More info is available here.

Hi vankatesh

I think u r missing at   RegisterStartupScript("Startup", scriptString);              

Use it
Page.RegisterStartupScript("Startup", scriptString);    

And if it is in Update panel ,Then 
ScriptManager.  RegisterStartupScript("Startup", scriptString);           like this.


Hope that this will help you.

Please overload right method as follow:

protected void btn_Click(object sender, EventArgs e)
    {
             ScriptManager.RegisterClientScriptBlock(this, GetType(), "alert", "test();", true);
          
          // --- (OR) Simple call alert.

 

            ScriptManager

 

.RegisterClientScriptBlock(this, GetType(), "alert", String.Format("alert('Hello');"), true);

 

 

 

 

   }
Here test() is ur javascript function.and btn control is in UpdatePanel.
