Question

I want to add DatatGridViewComboBoxCell into dynamically determined cells onto the datagridview.

So far all of the examples I have found either make the entire columns’ cells into comboboxes or don’t work.

Here is the simplest example that I can come up with. I have tried databinding to sources which work to a point. The items exist in the combobox.items but on the datagridview the combobox is empty and you cannot select a value

DataGridArticles.Columns.Add("columna", "columna")
Dim combo As New DataGridViewComboBoxCell

combo.Items.Add("b")
combo.Items.Add("ba")
combo.Items.Add("ca")

DataGridArticles.Rows.Add()
DataGridArticles.Rows(0).Cells(0) = combo

Is it possible to add a combobox to a specific cell in a datagridview.

Answer 1

I’ve never had any problems with DataBound DataGridViewComboBoxCell.

I’m using it like this:

Dim cell As New DataGridViewComboBoxCell()
cell.DisplayMember = "Name"
cell.ValueMember = "Id"
cell.DataSource = list

DataGridArticles.Rows(0).Cells(0) = cell

cell.Value = 0 //It will select and display item with Id = 0, if you do not set it
               //then combobox will look exactly like yours on image posted (like
               //there is no items in it).

It worked flawlessly every time I used it. So if it does not work for you may.

So to fix your problem add this line after adding items to combobox:

combo.Value = "b";

Hope it helps 🙂
