In my application's login control, I am showing a dialog window if the login failed. In this way:
protected void EMSLogin_Authenticate(object sender, AuthenticateEventArgs e) {
log.Info("=============INSIDE EMSLogin_Authenticate======");
RadTextBox UserName = EMSLogin.FindControl("UserName") as RadTextBox;
RadTextBox Password = EMSLogin.FindControl("Password") as RadTextBox;
if (Membership.ValidateUser(UserName.Text, Password.Text)) {
FormsAuthentication.RedirectFromLoginPage(UserName.Text, false);
} else {
ClientScript.RegisterStartupScript(typeof(ScriptManager), "CallShowDialog", "showDialog();", true);
}
}
The JavaScript is:
function showDialog() {
$(document).ready(function () {
$(".jym").dialog("open");
});
}
Now if the login failed the dialog is showing. But The problem is if I refresh the browser window, after one login failed, the dialog again opened, since the $(".jym").dialog("open")
is written in the page. Then I have tried
protected void Page_Unload(object sender, EventArgs e) {
log.Info("=============INSIDE Page_Unload======");
ClientScript.RegisterStartupScript(typeof(ScriptManager), "CallShowDialog", "", true);
}
But no luck.
Is there any way to solve this problem?
If I use ClientScript.RegisterClientScriptBlock()
this not working, I mean the dialog is not opening on error.

Try calling the function:
...in the Page_Load event handler.
Page_Load occurs before the button click event handler. You can verify this by adding the following code and looking in the debug/output window:
So erasing the script in the Page_Load event handler should clear any previous script that was loaded.
