For your second question, how to delete the cells information values only when pressing the Delete key? You need to create a custom DataGridView inherit from the standard DataGridView and override the ProcessCmdKey method.
Code Block
class CustomDGV : DataGridView
{
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.Delete)
{
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
}
