Prevent User to Press Enter in TextBox

Hi

try this example to prevent form to Submit when user Press Enter in TextBox Control

Just add this code to your Page_Init method of the page where you want this behavior:

protected void Page_Init(object sender, EventArgs e)
 {
   TextBox1.Attributes.Add(“onkeydown”,“if(event.which || event.keyCode){if (event.keyCode == 13) return false;}”);
 }

Good Luck
