Asp.net Server Side Show Js Alert Box, Doesn't Work When Using Partial Post Back
I have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown. public
Solution 1:
You have to register the script with the ScriptManager:
ScriptManager.RegisterStartupScript(this, typeof(Page), UniqueID, "alert('hi')", true);
Here is some more information:
Inline Script inside an ASP.NET AJAX UpdatePanel
Solution 2:
You should use ScriptManager.RegisterStartupScript instead:
<%@ Page Language="C#" AutoEventWireup="true" %>
<scriptrunat="server"type="text/C#">
protected voidBtnClick(object sender, EventArgs e)
{
string alertScript = "alert('Hello');";
ScriptManager.RegisterStartupScript(this, GetType(), "Key", alertScript, true);
}
