[Solved] RadComboBox not posting back

[Shane]

I have a RadComboBox that has checkbox in it.

            <telerik:RadComboBox ID="cmbColumns" runat="server" Skin="Sunset"  Text="Show Columns" AllowCustomText="true" ToolTip="Show Columns" EnableTextSelection="false"
                DataSourceID="ColumnsDataSource" AutoPostBack="true" EmptyMessage="Show Columns" >
                <ItemTemplate>
                    <asp:CheckBox ID="cbColumn" runat="server"
                        oncheckedchanged="cbColumn_CheckedChanged" Text='<%# Eval("Column") %>'  />
                </ItemTemplate>
                <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
            </telerik:RadComboBox>

When the first Item checkbox is selected or deselected the combobox does not postback.

If any other checkboxes are selected or deselected the combobox does postback.

Any suggestions??

Also when the checkbox is rendered for the first time the Text "Show Columns" is displayed.  Once something is selected it changes to System.Data.DataRowView.  Is it possible to persist "Show Columns" no matter what is selected?

Actually the first item checkbox posts back the first time it is selected but does not postback at all after that.
