GridDropDownColumn in Detail Table

[James]

I've been trying to dynamically bind a list to the data source of a GridDropDownColumn in a detail table. I have manage to get it to mostly work, but it isn't binding the first row's cell. I've been using the code below in various radGrid1 subs, and I keep getting the same results. I believe that I'm binding the data source after the first row is created and bound, but where do i put it so I can bind the data source before the first one.

Thanks for any help.

If (e.Item.OwnerTableView.Name = "DetailTable") Then

 

    If _list Is Nothing Then

        _list = Managers.DataManager.LoadAll

    End If

 

    'set the data sourse

    If TypeOf e.Item Is GridDataItem Then

 

        If Not _IsBound Then

            Dim item As GridDropDownColumn = TryCast(e.Item.OwnerTableView.GetColumnSafe("ddcCondition"), GridDropDownColumn)

            Dim itemManager As GridDropDownColumnEditor = TryCast(item.ColumnEditor, GridDropDownColumnEditor)

            itemManager.DataSource = _list

            itemManager.DataBind()

            _IsBound = True

        End If

    End If
End If

Hello James,

In which event you have tried to bind the GridDropDownColumn?. Try to bind it inside RadGrid's ItemCreatedEvent and check whether it works now.

VB.Net:

Protected Sub RadGrid1_ItemCreated(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem AndAlso e.Item.OwnerTableView.Name = "DetailTable" Then
        Dim item As GridDropDownColumn = TryCast(e.Item.OwnerTableView.GetColumnSafe("ddcCondition"), GridDropDownColumn)
        Dim itemManager As GridDropDownColumnEditor = TryCast(item.ColumnEditor, GridDropDownColumnEditor)
        itemManager.DataSource = _list
        itemManager.DataBind()
        _IsBound = True
    End If
End Sub

Thanks,
Princy.

I've tried RadGrid1_ItemDataBound and RadGrid1_ItemCreated with the same results (not binding the first cell), and I also tried RadGrid1_DetailTableDataBind and that just plain didn't work.

Hello James,

I also tried Princy's solution and it works nice here. I am attaching it in a sample project.

All the best,
