Question

     private void item_grid_CellClick(object sender, DataGridViewCellEventArgs e)
    {
         if (e.ColumnIndex==taxone_col_index || e.ColumnIndex==taxtwo_col_index)
        {


        }

    }

    private void item_grid_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == (char)Keys.Return)
        {
            e.Handled = true;

           item_grid.CellClick; // i did this but its not working            }
    }

i want to perform the cell click event from keypress event. how to do it?

Answer 1

It sounds like what you want is to know the row and column index of the cell that the key is pressed in. From that you will then be able to look up the value of the cell.

To do this just use the CurrentCell property of the DataGridView.

Trying to artificially create a CellClick is just asking for trouble.

One thing to note is that you will probably need to handle the EditingControlShowing event and attach a KeyPress handler to the underlying editing control since typing into a DataGridView cell does not raise the grid level KeyPress event.

If you really want to create a CellClick event you will need to subclass the DataGridView control, and create your own RaiseCellClick() method which then calls the protected OnCellClick() method:

public void RaiseCellClick(int row, int column)
{
    DataGridViewCellEventArgs e = new DataGridViewCellEventArgs(row, column);
    base.OnCellClick(e);
}

But even this doesn’t particularly help you since the DataGridViewCellEventArgs needs to take the row and column indexes in its constructor.
