[Solved] Hiding Hierarchy Expand Icon based on MasterTable Value

[Mark Rowe]

Hey,

I am having a problem hiding the expand icon on a Grid.  I've been trying to follow the examples in the documentation, but I'm trying to do it a little different than what is posted.  I have a column in the master view that tells me if I have additional records in a detail table.  So I'm trying to utilize this column in order to show or hide the expand icon.

Here is an example of what I have so far, but I must admit, I'm really lost.

  Dim nestedViewItems As GridItem() = tableView.GetItems(GridItemType.Item)
            For Each nestedViewItem As GridItem In nestedViewItems
                If nestedViewItem.DataItem("AdditionalAddresses") > 0 Then
                    Dim NestedGridItem As GridNestedViewItem = NestedGridItems(nestedViewItem.ItemIndex)
                    Dim cell As TableCell = NestedGridItem.NestedTableViews(0).ParentItem("ExpandColumn")
                    cell.Controls(0).Visible = False
                    nestedViewItem.Visible = False
                End If
            Next

I am getting in the if statement based on my "AdditionalAddresses" column, however, I can't seem to find out how to reference the "expandColumn" cell.

Thanks,
Bob

Hi Bob,

I hope the 'AdditionalAddresses' is the column in the master table which gives information about the additional records in the detail table. If so you may try the following code snippet in the ItemDataBound event to hide the ExpandCollapse image icon.

VB:

    Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
        If TypeOf e.Item Is GridDataItem Then
            Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
            If item("AdditionalAddresses").Text = "SomeText" Then
                Dim cell As TableCell = DirectCast(item("ExpandColumn"), TableCell)
                cell.Controls(0).Visible = False
            End If
        End If
    End Sub

Thanks
