Hi, 

Ran into this issue while testing with the gridgroupingcontrol with the allowremove tag overriding the readonly gridcolumndescriptor. For example, when entering edit mode with the following code it functions as intended, with the SID column greyed out. However, when toggling the AllowRemove flag to True it becomes editable.

Is there a proper way to enable removing rows that i'm missing? Should I be using baritems and parsing those instead?

 <syncfusion:GridGroupingControl ID="Testing" runat="server" AutoFormat="Monochrome"
                    EnableCallbacks="False" ShowGroupDropArea="False" DataSourceCachingMode="ViewState" DataMember="DefaultView">
                    <TableDescriptor AllowEdit="true" AllowRemove="false" AllowNew="true">
                        <Columns>
                            <syncfusion:GridColumnDescriptor MappingName="SID" HeaderText="SID" ReadOnly="true"/>
                            <syncfusion:GridColumnDescriptor MappingName="Name" HeaderText="SiteName"/>
                        </Columns>
                    </TableDescriptor>
  </syncfusion:GridGroupingControl>

Also, when I hit enter the update processes but doesn't exit the edit mode even though have set event args as per your examples with:
            e.Cancel = true;
            e.Handled = true;
at the end.

Any tips would be appreciated.

To assist in those who may run into losing tabledescriptors on setting values to null, the flag you need to set is 
AllowResetTableDescriptorWhenDataSourceSetNull="false"
in the ggc declaration. I missed that and that's what was causing all of my issues.

Cheers
