Example

This example demonstrates how the default browser processing of the Enter key, pressed while an ASPxTextBox has input focus, can be canceled with the help of a specific client method of a service ASPxClientUtils client object.

Note that the client script implementing the ASPxClientUtils object should be explicitly registered, to make this object available on the client:

C#

protected void Page_Load(object sender, EventArgs e){
    DevExpress.Web.ASPxWebControl.RegisterBaseScript(Page);
}

ASPX

<dxe:ASPxTextBox ID="ASPxTextBox1" runat="server" Width="170px">
    <ClientSideEvents KeyPress="function(s, e) {
        if(e.htmlEvent.keyCode == 13) {
            alert(&quot;Enter&quot;);
            ASPxClientUtils.PreventEventAndBubble(e.htmlEvent);
        }
    }" />
</dxe:ASPxTextBox>
