Click event when Enter button is Pressed in asp.net

Click event when Enter button is Pressed in asp.net

Javascript

function clickButton(e, buttonid){

      var evt = e ? e : window.event;

      var bt = document.getElementById(buttonid);

      if (bt){

          if (evt.keyCode == 13){

                bt.click();

                return false;

          }

      }

}

//code behind TextBox1.Attributes.Add("onkeypress", "return clickButton(event,'" + Button1.ClientID + "')");
 
The code behind generates the following code:

<    asp:Button id="Button1"
           Text="Submit"
           OnClick="SubmitBtn_Click" 
           runat="server" onkeypress="return clickButton(event,'Button1')"/   >

This causes web control Button1 to be clicked when the enter key is hit inside TextBox1.
