Please help me !
Thanks!
Hi Xu Guochun,
Please set the property of PagingDataRetrievalMode to ReturnPartialRows in the properties. It should work with your issue. If it won't work, could you give me a simple runable sample so that we could test it here?
Hope it helps.
Regards,
Lili Khiung

Have you try to enable the PagingDetectPartialGroupRows property? You can enable it in WebGrid.Designer > Popular Settings > Automatically detect partial grouped rows (for classic paging). Please inform me about the result.
Hi Lili Khiung,
I set the PagingDetectPartialGroupRows property to "true" , but the problem persists.
<ISWebGrid:WebGrid ID="GridHandle" runat="server" Width="99%" DefaultStyleMode="Win7" OnInitializeRow="WebGrid1_InitializeRow" UseDefaultStyle="True" DataSourceID="ISDataSource1" DataMember="Messages_Center"> <LayoutSettings PagingMode="ClassicPaging" PagingLoadMode="Custom" PagingSize="20" PagingDetectPartialGroupRows="true"> </LayoutSettings>
</ISWebGrid:WebGrid>
Now it's Ok!
thanks a lot!
