how to add items in combox dynamically in tablelayoutpanel in vb.net

Question

i have comboboxes dynamically created in a tablelayoutpanel and i want to add items to that combobox dynamically( i dont want to use data sources).

here is my code

 Dim cmb(maxx)

    For a = 0 To maxx - 1
        TableLayoutPanel1.Height += 31
        TableLayoutPanel1.RowStyles.Add(New RowStyle(SizeType.Absolute, 30))
        TableLayoutPanel1.RowCount += 1
        TableLayoutPanel1.Controls.Add(New CheckBox With {.Text = CopyaillongoDataSet.inventory.Rows(a).Item(1).ToString, .Font = New System.Drawing.Font("Microsoft Sans Serif", 10)}, 0, TableLayoutPanel1.RowCount - 1)
        TableLayoutPanel1.Controls.Add(New ComboBox With {.Name = cmb(a), .MaxDropDownItems = 10, .DropDownStyle = ComboBoxStyle.DropDownList}, 1, TableLayoutPanel1.RowCount - 1)
        cmb(a).items.add(a)
    Next

i assigned a name to a combobox and tried to use that name to add items but were unsucessful. is it possible to create items dynamically with a combobox dynamically created? if so, can you help me? i am working on my thesis and i need to get rid of this problem. thank you for those who can help.

You can't reference a control by just a string name the way you are doing it in your code (you didn't post what you are doing between Dim cmd(maxx) and the loop, but I'm guessing you want to do something like this, where you create a new ComboBox control and add it to the Panel:

Dim newCombo As New ComboBox With {.MaxDropDownItems = 10,
                                   .DropDownStyle = ComboBoxStyle.DropDownList}
newCombo.Items.Add(a)
TableLayoutPanel1.Controls.Add(newCombo, 1, TableLayoutPanel1.RowCount - 1)

You can reference the control later with TableLayoutPanel1.GetControlFromPosition(column, row) function.
