Error encountered when attempting to display an alert using ClientScript.RegisterStartupScript within an UpdatePanel

Currently, I'm in need of displaying a Success Message and upon clicking OK, it should automatically Redirect me to another Page. While everything was working perfectly, the introduction of an UpdatePanel seems to have caused the Alert not to show up.

Here is my code: 

ClientScript.RegisterStartupScript(typeof(Page), "Create Time Table", "<script language='JavaScript'>alert('Time Table Created Successfully.'); window.location.href = 'create.aspx';</script>");

I have also attempted the following variations: 

ClientScript.RegisterStartupScript(typeof(Page), "Create Time Table", "<script language='JavaScript'>alert('Time Table Created Successfully.'); window.location.href = 'create.aspx';</script>", true);

ClientScript.RegisterStartupScript(typeof(Page), "Create Time Table", "<script language='JavaScript'>alert('Time Table Created Successfully.'); window.location.href = 'create.aspx';</script>", false);

Unfortunately, these solutions did not work as expected.

Answer №1

For those using an update panel, provide the update panel ID and its type as shown below:

ScriptManager.RegisterStartupScript(
                UpdatePanelID,
                UpdatePanelID.GetType(), 
                "Create Time Table", 
                " alert('Time Table Created Successfully.'); window.location.href = 'create.aspx';",
                true);
