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,'');" />
                <br /><br /><br />
                <asp:Button runat="server" ID="btnRemove" style="width: 30px; height: 30px; font-size: 10px; font-weight: bold; text-align: left;" Text="<<" OnClick="btnRemove_Click" OnClientClick="return disableButtonAndPostback(this,'');" />
            </td>

I may have just solved this issue by setting the EnableViewState to false 

I found the information about the view state here:
