Direct access to DataGridView combobox in one click?

I'm getting annoyed with clicking once to select a row in the datagridview, and then clicking again to click on a control in that row (in this case a combobox).

Is there a way configure this thing so that a开发者_运维技巧ll this can be done in one mouse click instead of two?

Change the EditMode property of your DataGridView control to "EditOnEnter". This will affect all columns though.

If you want to selectively apply the one-click editing to certain columns, you can switch the current cell during the MouseDown event to eliminate the click to edit:

// Subscribe to DataGridView.MouseDown when convenient
this.dataGridView.MouseDown += this.HandleDataGridViewMouseDown;

private void HandleDataGridViewMouseDown(object sender, MouseEventArgs e)
{
    // See where the click is occurring
    DataGridView.HitTestInfo info = this.dataGridView.HitTest(e.X, e.Y);

    if (info.Type == DataGridViewHitTestType.Cell)
    {
        switch (info.ColumnIndex)
        {
            // Add and remove case statements as necessary depending on
            // which columns have ComboBoxes in them.

            case 1: // Column index 1
            case 2: // Column index 2
                this.dataGridView.CurrentCell =
                    this.dataGridView.Rows[info.RowIndex].Cells[info.ColumnIndex];
                break;
            default:
                break;
        }
    }
}

Of course, if your columns and their indexes are dynamic, you would need to modify this a bit.
