Is it possible to replace the <a> elements inside the ConfirmTemplate (below) for Ok and Cancel with RadButtons ? :
<a tabindex="0" id="confirmOk" name="confirmOk" onclick="$find('{0}').close(true);" class="rwPopupButton" href="javascript:void(0);">
<%= WebResources.SearchInOk %></a>
<telerik:RadButton ID="btn1" runat="server" Text="Test" />
<a tabindex="1" id="confirmCancel" name="confirmCancel" onclick="$find('{0}').close(false);" class="rwPopupButton" href="javascript:void(0);">
<%= WebResources.SearchInCancel %></a>
<a tabindex="0" id="confirmOk" name="confirmOk" onclick="$find('{0}').close(true);" class="rwPopupButton" href="javascript:void(0);">
<%= WebResources.SearchInOk %></a>
<telerik:RadButton ID="btn1" runat="server" Text="Test" />
<a tabindex="1" id="confirmCancel" name="confirmCancel" onclick="$find('{0}').close(false);" class="rwPopupButton" href="javascript:void(0);">
<%= WebResources.SearchInCancel %></a>
