hide expand collapse column in radgrid based on child grid values

 Hi Team,

 

I don't want to display the expand/collapse icon if the child grid doesn't contain values.

It should display only the child grid has rows.

 

Thanks,
Rajesh

Dim dataItem As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)
Dim obj As New AutoComplete()
Select Case e.DetailTableView.Name
Case "ComponentDetails"
Dim InventoryID As Integer = CType(dataItem.GetDataKeyValue("InventoryID"), Integer)
e.DetailTableView.DataSource = obj.GetComponentItems(InventoryID)
End Select
End Sub
