Radmenu item not fire when press Enter in RadTextBox

[Howard]

I am using javascript to trigger the radmenu item. But when I enter value in textbox and press "Enter", the page is postback without trigger the radmenu item. my code as below:

Javascript:

function CkKeyPress(e) {
      var evt = (e) ? e : window.event;
      var key = (evt.keyCode) ? evt.keyCode : evt.which;
      if (key == 13) {
           var dealer = document.getElementById('<%=textbox1.ClientID%>').value;
                        var menu = $find("<%= radMenu1.ClientID%>");
                        var templateButton = menu.findItemByText("Next");
                        templateButton.click();
            }
}

Asp.net

<telerik:RadMenu ID="radMenu1" runat="server" Style="top: 0px; left: 0px">
     <Items>
            <telerik:RadMenuItem runat="server" Text="Next" Value="Next">
             </telerik:RadMenuItem>
      </Items>
</telerik:RadMenu>

<telerik:RadNumericTextBox ID="txtAmount" runat="server" Culture="en-US" DbValueFactor="1" LabelWidth="64px" Width="160px" AutoCompleteType="Disabled" onkeypress="CkKeyPress(event)">
</telerik:RadNumericTextBox>

Vb.net

Private Sub radMenu1_ItemClick(sender As Object, e As RadMenuEventArgs) Handles radMenu1.ItemClick
       Response.Redirect("sample.aspx")
End Sub

I am using vs 2012 and telerik 2013

Hi Howard,

Please try to ajaxify the RadMenu to avoid the postback and attach the RadMenu OnItemClick event in ASPX also. Please have a look into the following code snippet.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="radMenu1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="radMenu1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadMenu ID="radMenu1" runat="server" OnItemClick="radMenu1_ItemClick" Style="top: 0px;
    left: 0px">
    <Items>
        <telerik:RadMenuItem runat="server" Text="Next" Value="Next">
        </telerik:RadMenuItem>
    </Items>
</telerik:RadMenu>
<telerik:RadNumericTextBox ID="txtAmount" runat="server" Culture="en-US" DbValueFactor="1"
    LabelWidth="64px" Width="160px" AutoCompleteType="Disabled" onkeypress="CkKeyPress(event)">
</telerik:RadNumericTextBox>

Thanks,
Princy.
