[Solved] Hierarchical grid change header depending on parent data

[Joerg]

I need to change the header of a column in detailview to a data value of the parent row. I tried to achive this with the following code in the ItemDataBound-event, but it does not work.

        If e.Item.OwnerTableView.Name = "Level2" And e.Item.ItemType = Telerik.WebControls.GridItemType.Header Then

            Dim header As Telerik.WebControls.GridHeaderItem = CType(e.Item, Telerik.WebControls.GridHeaderItem)
            header("Rabatt").Text = e.Item.OwnerTableView.ParentItem.Cells(5).Text

        End If

Anyone got an idea?

Hi,

Try out the following code snippet in the PreRender event to achieve the desired scenario.

VB:

Protected Sub RadGrid1_PreRender(sender As Object, e As EventArgs)
    For Each parentitem As GridDataItem In RadGrid1.MasterTableView.Items
        If parentitem.Expanded Then
            Dim strTxt As String = parentitem("columnUniqueName").Text
            Dim childtable As GridTableView = DirectCast(parentitem.ChildItem.NestedTableViews(0), GridTableView)
            For Each childHeader As GridHeaderItem In childtable.GetItems(GridItemType.Header)
                childHeader("Rabatt").Text = strTxt
            Next
        End If
    Next
End Sub

Cheers
Shinu.
