page_load の間、タイマーを無効にします。Button1 を押すと、タイマーが有効になりますが、ページが更新されます。したがって、timer_tick1 に達することはありません。ボタンがクリックされてから一定時間後にポップアップを表示する必要があります。更新が行われないようにするにはどうすればよいですか?
アラート クラス
public static class Alert
{
public static void Show(string message, Page page)
{
// replaces the quotations to follow the script syntax
// quotations are interpretated as \\' in script code
string cleanMessage = message.Replace("'", "\\'");
string script = "<script type=\"text/javascript\">alert('" + cleanMessage + "');</script>";
// Gets the executing web page
Page tempPage = page;
// Checks if the handler is a Page and that the script isn't already on the page
if (tempPage != null & !tempPage.ClientScript.IsClientScriptBlockRegistered("alert"))
{
tempPage.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script); // this isn't working, but it works on a button click event.
}
}
}
ページ クラス
public partial class Test1 : System.Web.UI.Page

DateTime.Now.ToLongTimeString(); // Checks if page reloads

{ // i added a breakpoint here. It doesn't even pass through.
Alert.Show("hehehehe", this); //PopUp Shows up.
Timer1.Enabled = false; //Cancels Timer
Label1.Text = "Panel refreshed at: " +
