I have a page that contains a textbox and button, when the user clicks the submit button I want to display a message based on a bool value.

I have researched on stackoverflow and tried the code in this questions: Asp.net Webform Display Alert and redirect

But it didn't work. I have the following code:

ClientScript.RegisterStartupScript(this.GetType(),, alert('message'), true);

What code do I need to display the alert message?

you can use this simple method:

    private void MessageBox(string msg)

{

    Label lbl = new Label();

    lbl.Text = <script language='javascript'> + Environment.NewLine + window.alert(' + msg + ')</script>;

    Page.Controls.Add(lbl);

}
