hii ranjan,

try this in your code behind

ScriptManager.RegisterStartupScript(this,GetType(),"showalert","alert('"+ex.Message.ToString()+"');",true);

and write the following javascript function in aspx

function Showalert() {
alert('Call JavaScript function from codebehind');
}

you can try like this

catch (Exception ex)
        {
            Response.Write("");
        }

Hi,
I suggest not to display the exception message thru javascript, instead show it by using Label.
You can do using script like this

private void Btn_Click(object sender, EventArgs e)
{
try
{
int a = 10;
int b = 0;
int r = a/b;
}
catch (Exception exception)
{
String scriptText = "alert('Error - " + exception.Message + "')";
ClientScript.RegisterOnSubmitStatement(this.GetType(),
"ErrorAlert", scriptText);

}
}

Regards,
Iftikar

If it's Windows Forms, something like:

catch (Exception e)
{
MessageBox.Show(e.Message);
}
