Hi all,
I'm working with Telerik Web UI 2014.2.724.45
My Master Grid has some Sub Grids, but the Expand/Collapse button not show even though the Sub Grids have values
I used IE Developer Tool to view HTML source and found that the "<tr>" has inline style "display: none;" I remove this style then the Sub Grids appears.
Also, as I observed, the Sub Grids have Expand/Collapse button for their Sub Grids (level2). (see attachment)
---------------------------------------------------------------------
PrintableRadGrid inherits RadGrid
<trstk:PrintableRadGrid id="ListRadGrid" AutoGenerateHierarchy="false" AutoGenerateColumns = "false"
AllowPaging="true" OnItemCreated="ListRadGrid_ItemCreated" OnNeedDataSource="ListRadGrid_NeedDataSource"
OnDetailTableDataBind="ListRadGrid_DetailTableDataBind" runat="server" Visible="false">
<MasterTableView NoDetailRecordsText="No records to Display" HierarchyLoadMode="Client"
PageSize="10" AllowCustomPaging="true" AutoGenerateColumns="false" TableLayout="Auto">
</MasterTableView>
<PagerStyle AlwaysVisible="true" />
</trstk:PrintableRadGrid>
Please help.

I bind Master view by NeedDataSource event
Then run DetailTableDataBind event for loading Sub Grid.
When view HTML for Master Grid, I don't see the element <td class="rgExpandCol"> in the <table> of Master Grid. But the Sub Grids have this element.
I think code behind does not generate Expand/Collapse column for Master Grid but not sure about the root cause.
Thanks

Hello Phat,
From the provided information only it would be impossible to determine what is causing the issue on your end. Additionally, please note that we do not support custom controls, even if they inherit controls from our suite and it is possible that the problem is related to the custom control. I could suggest that you try with standard RadGrid and see if you will observe the same issue.
Finally, you could inspect the Columns collection of the MasterTableView within the PreRender event of the grid and see if the Collapse/Expand column is present in it.
