Hi,
I am getting an error "column orderNumber does not belong to table GroupedTable0" when trying to achieve grouping by drag and drop facility.
Please have a look into the following codesnippet.
....
<Columns>
<telerik:GridButtonColumn DataTextField="OrderNumber" CommandName="BtnLinkPO" HeaderText="Order No." UniqueName="BtnOrderNumber" Groupable="false" SortExpression="OrderNumber">
<ItemStyle Font-Bold="True" ForeColor="Green" />
</telerik:GridButtonColumn>
<telerik:GridBoundColumn DataField="OrderDate" HeaderText="Order Date" UniqueName="OrderDate" DataType="System.DateTime" DataFormatString="{0:dd/MM/yyyy}"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Cost" HeaderText="Cost" Aggregate="Sum" DataFormatString="{0:###,##0.00}" FooterAggregateFormatString="<strong>{0:###,##0.00}</strong>" UniqueName="GrossCost" Groupable="False">
<FooterStyle HorizontalAlign="Right" />
<ItemStyle HorizontalAlign="Right" />
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="ClientPO" HeaderText="Client PO No." UniqueName="ClientPO"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Authoriser" HeaderText="Authoriser" UniqueName="Authoriser"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="ActivityID" HeaderText="Activity ID" UniqueName="ActivityID"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="UserID" HeaderText="User ID" UniqueName="UserID"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Business" HeaderText="Business" UniqueName="Business"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Brand" HeaderText="Brand" UniqueName="Brand"></telerik:GridBoundColumn>
</Columns>
...
Thanks in advance.
