This problem only started after an upgrade to Version 2013.3.1324.45, previous version had no issues for 5+ years
I have a page with two grids where we move records between the two. If a user manually resizes any column in either grid I get the error below and it does not fire my code behind function. everything works fine if you don't resize.
GRID 1
<telerik:radgrid runat="server" ID="UnAssignedStudentGrid"
GridLines="None" Skin="Default" Height="300" Width="300" AllowMultiRowSelection="True" AllowSorting="False"
NeedDataSource="gvSearchResults_NeedDataSource" OnPreRender="gvSearchResults_PreRender">
<itemstyle backcolor="#fbfbfb" />
<alternatingitemstyle backcolor="#f7f7f7"/>
<ClientSettings>
<Selecting AllowRowSelect="True" />
<Scrolling AllowScroll="True" UseStaticHeaders="True" />
<Resizing AllowColumnResize="True" />
</ClientSettings>
</telerik:radgrid>
GRID 2
<telerik:radgrid runat="server" ID="AssignedStudentGrid"
GridLines="None" Skin="Default" Height="300" Width="300" AllowMultiRowSelection="True" AllowSorting="False"
NeedDataSource="gvSearchResults_NeedDataSource" OnPreRender="gvSearchResults_PreRender">
<itemstyle backcolor="#fbfbfb" />
<alternatingitemstyle backcolor="#f7f7f7"/>
<ClientSettings>
<Selecting AllowRowSelect="True" />
<Scrolling AllowScroll="True" UseStaticHeaders="True" />
<Resizing AllowColumnResize="True" />
</ClientSettings>
</telerik:radgrid>
Add/Remove Buttons
<td style="vertical-align: middle;" align="center">
<asp:Button runat="server" ID="btnAdd" style="width: 30px; height: 30px; font-size: 10px; font-weight: bold; text-align: left;" Text=">>" OnClick="btnAdd_Click" OnClientClick="return disableButtonAndPostback(this,'');" />
