[Robert Jakech]

I have a radgrid from which i insert/edit records via a usercontrol.

In my code behind, i want to call RadAlert when my textbox is empty.

I have read alot of examples and non of them suites my problem.

Here is the code 

.ASPX(page)

    protected void IntakeUpdate(object sender, EventArgs e)

    {

        ParameterManager.IntakeUpdate(Convert.ToInt32(IDTextBox.Text), IntakeTextBox.Text);

    }

}

Now, What i want to do is within Protected void IntakeUpdate(object sender, EventArg e) method.

I want to write something like

If(IntakeTextBox.Text==String.Empty)

{

RadAjaxManager1.ResponseScripts.Add(@"radalert('You can't update empty fields <b>Prometheus</b>!', 330, 210);");

}

else

{

//Update the records

}

I need to return an alert.

But when i click the button, nothing happens.

Please, I desperately need your help.

thanks.
