Having a drop-down cell on datagrid

[J Trahair]

Is there a way of giving a cell a drop down combobox with a small number of choices in it, eg. choosing a currency symbol? In VB6 there was BuildCombo etc.

Thank you.

Copied from a recent post by JohnH :-

Dim cell As New DataGridViewComboBoxCell
cell.Items.Add("A")
cell.Items.Add("B")
Me.DataGridView1.Item(col, row) = cell

Just add a Combobox column to the DataGridView when you configure its columns.

Can we clarify - is this question about a single cell, or a whole column?

 

[J Trahair]

This will be for all cells in a given column, except where there is no value in column 2 in that row (for example).
Eg. column 8 has the ComboBox if column 2 is valid.

Sorry, my mistake then - I took "giving a cell a drop down combobox" at its literal meaning.

Sorry, I should have explained it better to begin with.

I have a datagrid in VB 2005, where each cell in column 8 is a combobox contain currency symbols eg. £, €, $. When the user enters any cell in this column, they are forced to accept one of the currency symbols, and not to type in something else.

I tried

            Dim cell As New DataGridViewComboBoxCell
            cell.Items.Add("A")
            cell.Items.Add("B")
            Me.grd1.Item(grd1.CurrentCellAddress.X, grd1.CurrentCellAddress.Y) = cell

in grd1_CellEnter, but the behaviour was quirky and there were error messages. Plainly, that's the wrong place, although the code segment looks promising.

Where should I put the code, for best results? Thank you.

As I said, just add a combo column in Designer. You can also add the items there.
