EditingControlShowing event occurs when a control for editing a cell is showing.
Example
private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
e.Control.KeyPress -= new KeyPressEventHandler(NumColumn_KeyPress);
if (dataGridView1.CurrentCell.ColumnIndex == 2 || dataGridView1.CurrentCell.ColumnIndex == 3) // numeric columns
{
TextBox tb = e.Control as TextBox;
if (tb != null)
{
tb.KeyPress += new KeyPressEventHandler(NumColumn_KeyPress);
}
}
}
private void NumColumn_KeyPress(object sender, KeyPressEventArgs e)
{
if (!char.IsControl(e.KeyChar)
&& !char.IsDigit(e.KeyChar) && !char.IsPunctuation(e.KeyChar) )
{
e.Handled = true;
}
}
