So if you want to show the message on button click then why you assigned the function to
window.onloadevent,I just tried your code and put itPage_Loadand it was showing the alert message... :) So if you want to run it on button click the use the code belowstring msg = "You cannot select more seats.";
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("function ShowAlert(){");
sb.Append("alert('");
sb.Append(msg);
sb.Append("'); return false;};");
sb.Append("</script>");
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "alert", sb.ToString(), false);and button should be as
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="javascript:return ShowAlert();" />let me know if face any issue.

Hi Brij.... Thanks for your reply... actually i'm counting the number of buttons clicked by user with the value contained in a session variable....and when the no of clicks cross that value then i wanna display the alert message....if i'll put it on "onclientclick" property then how can i get the condition checked ??
