Calling a javascript function from Code-behind...

[brucegonewild]

How can I call a javaScript function that I've registered through this.Page.RegisterClientScript("key", scriptText)?

To be more precise, I need to pop up an error message (an alert) when a SystemException occurs in my code behind.

Ideas?

cheers!

Here's a lazy way of doing it:

response.write("<script language=javascript>alert('Error Message Here!');</script>")

Here's a slightly less lazy way of doing it:

public static void CreateMsgBox(System.Web.UI.Page aspxPage, string strMessage, string strKey)
{
	string strScript = "<script language = JavaScript>alert('" + strMessage + "')</script>";
	if (!aspxPage.ClientScript.IsStartupScriptRegistered(strKey))
	{
		aspxPage.ClientScript.RegisterStartupScript(aspxPage.GetType(), strKey, strScript);
	}
}

I use this in a "utilities" class on my website that I can call from any page. But the key is to use RegisterStartupScript.

HOpe this helps,

Alex
