[2005] Help with using TableLayoutPanel and dynamic Combobox

[jebritt]

Ok, I need some serious help with this. I've searched on the forums, googled, and expermimented as much as I can....all to no avail.

Here's the problem.

I'm using a TableLayoutPanel to dynamically configure a form based on values from a database. To the TableLayoutPanel, I dynamically add 1 Label, 1 Textbox, 1 Button, and 1 Combobox. Here's the root of the problem, If I have 2 or more rows in the TableLayoutPanel, ALL the Comboboxes change at the same time.

What do I have to do to only get 1 Combobox to change at a time??

Here's the code I'm using

 If lobjDS.Tables(0).Rows.Count > 0 Then
            Me.TableLayoutPanel1.SuspendLayout()
            For Each dr As DataRow In lobjDS.Tables(0).Rows
                llbl = New Label
                With llbl
                    .Text = dr("Description") & ":"
                    .Margin = New Padding(2, 2, 2, 2)
                    .TextAlign = ContentAlignment.MiddleRight
                    .Dock = DockStyle.Fill
                    .AutoSize = True
                End With

                lCombobox = New ComboBox
                With lCombobox
                    .Dock = DockStyle.Fill
                    .DisplayMember = "Description"
                    .ValueMember = "Value"
                    .DataSource = VDPOperators
                End With

                lTextbox = New TextBox
                With lTextbox
                    .Dock = DockStyle.Fill
                End With

                lButton = New Button
                With lButton
                    .Text = "AND"
                    .Height = 22
                    .Width = 38
                End With

                With Me.TableLayoutPanel1
                    .Controls.Add(llbl)
                    .Controls.Add(lCombobox)
                    .Controls.Add(lTextbox)
                    .Controls.Add(lButton)
                End With
            Next

            Me.TableLayoutPanel1.ResumeLayout()

Thanks for any suggestions!

What do you mean by "ALL the Comboboxes change at the same time"? Are you saying that if you change the selection in one ComboBox the selection changes in the others too? If so then your use of a TableLayoutPanel is not relevant to the problem. The issue would be that you're binding them all to the same data source, so there's only one CurrencyManager. If there's one CurrencyManager then there's one Current item, and it will be shown in all the ComboBoxes. What you need to do is create a new BindingSource for each new ComboBox. Bind your data to the BindingSource and the BindingSource to the control. Now each control has a different CurrencyManager so they can each have an independent selection.
