[Solved] How do I make a grid editable?

[Jonathan]

I have a grid which is bound to a simple data table.  I set AllowAutomaticUpdates=True, EditMode=inplace, and AllowMultiRowSelection=True.  My first column is a checkbox column, but it's not editable.  How can I make the checkbox colum allow user's to change it's value.  I'm sure it's something simple.

Thanks,

P.S.  Here is the ASPX for my grid:

        <telerik:radgrid id="gridFiles" runat="server" allowautomaticdeletes="True" allowautomaticupdates="True"
            allowmultirowselection="True" autogeneratecolumns="False" font-names="Arial"
            gridlines="None" oncolumncreated="gridFiles_ColumnCreated" ondeletecommand="gridFiles_DeleteCommand"
            onitemcommand="gridFiles_ItemCommand" onitemdeleted="gridFiles_ItemDeleted" skin="Web20">

I figured it out!  I was trying to add a checkbox column, which was always disabled.  The Column editor in the designer doesn't contain all the types of columns.  The following code worked great, but wasn't a valid option in the IDE:

<telerik:GridClientSelectColumn CurrentFilterFunction="NoFilter" FilterListOptions="VaryByDataType" UniqueName="column" >
<HeaderStyle Width="40px" />
</telerik:GridClientSelectColumn>
