    Hello, this is my code for bind a dropdowlist in ItemTemplate that has a Bind("field")

    it's work fine, but in Edit Mode one time in     
    list.DataSource = dsDropDown
    give the error:

        {"Object reference not set to an instance of an object."}
    Then in I'm using a catch for this error, and all is fine.

    Do you know a solution for don't use the catch?

      Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

        If (TypeOf e.Item Is GridDataItem AndAlso e.Item.IsDataBound) Then

            Dim dsDropDown As New DataSet()
            OleDbCnn = New Data.OleDb.OleDbConnection(Session("CONNECT_DBS"))
            Dim item As GridDataItem = e.Item
            Dim list As DropDownList = item.FindControl("DDL_AREA_GEOGRAFICA_NAME")
            OleDbSql = Area_Geografica_Code()
            Dim OleDbDad As New Data.OleDb.OleDbDataAdapter
            OleDbDad = New Data.OleDb.OleDbDataAdapter(OleDbSql, OleDbCnn)
            list.DataSource = dsDropDown
            list.DataTextField = "NAME"
            list.DataValueField = "CD_CODE"
          Catch ex As Exception
          End Try

        End If 

      End Sub

    Thanks for any help
