Need help with creating a server-side validation alert that appears when the user tries to close the browser, and prevents the page from closing after the alert is displayed. The solution must be done entirely in the Codebehind with no code in the aspx page. Ideally, looking for a code snippet for .NET 1.1.
Check out this code snippet..
Use ScriptManager to register a startup script in C#:
ScriptManager.RegisterStartupScript(this, GetType(), "alert", "alert('Data saved successfully');", true);
When performing validation in CodeBehind, consider incorporating Javascript onto the page.
This resource explains how to display a popup using JavaScript when the tab is closed. To insert plain text (JavaScript), utilize a LiteralControl within your HTML code.
Snippet of Code:
if (warningNeeded)
{
LiteralControl lc = new LiteralControl();
lc.Text = string.Concat("<script type=\"text/javascript\">",
"window.onUnLoad= function (evt) {",
"alert('YourAlert');",
"}",
"</script>");
this.Controls.Add(lc);
}
After shutting down the browser, specific server-side tasks need to be executed.
If there is an error during these server-side operations, an alert message stating "Operation Unsuccessful" should be displayed and the browser must remain open.
Otherwise, proceed to close the browser.
