[Solved] Errors When AutoGenerateColumns = False

[Jeremy Yoder]

I had AutoGenerateColumns set to True, pointed my dataset to RadGrid1.DataSource, and everything worked fine. Now I set AutoGeneateColumns to False and manually add the columns. Here's my simplified code for test purposes...

    Protected Sub CreateColumns(ByVal ds As DataSet)
        RadGrid1.Columns.Clear()
        RadGrid1.AutoGenerateColumns = False
        Dim dt As DataTable = ds.Tables(0)
        For i As Integer = 0 To dt.Columns.Count - 1
            AddColumn(dt.Columns(i).ColumnName)
        Next
    End Sub

    Protected Sub AddColumn(ByVal strColumnName As String)
        Dim col As New GridBoundColumn
        col.DataField = strColumnName
        col.HeaderText = strColumnName
        RadGrid1.Columns.Add(col)
    End Sub

After doing this, if I click on the Header to sort the column, the grid does not sort, and all the HeaderText along the top disappears. Filtering also throws this error: "is neither a DataColumn nor a DataRelation for table DefaultView". Am I missing some setting? If it helps, here's my RadGrid...

        <telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True" AllowPaging="True"
            AllowSorting="True" GridLines="None" AutoGenerateColumns="False">
            <ClientSettings>
                <Selecting AllowRowSelect="True" />
            </ClientSettings>
        </telerik:RadGrid>

I think you may need to define a bit more with the RadGrid than what you are currently doing. If you follow the example from this documentation article I think you can solve the issue you are running into.
