Hello Tooraj,

Thank you for writing.

I am afraid we do not support adding a new row through key press events out of the box. However, you can implement this yourself by using a custom grid behavior. Please consider the following code as an example:

private void Form1_Load(object sender, EventArgs e)
{
    this.radGridView1.GridBehavior = new CustomGridBehavior();
}
 public class CustomGridBehavior : BaseGridBehavior
    {
        public override bool ProcessKeyDown(KeyEventArgs keys)
        {
            if (keys.KeyCode == Keys.Down)
            {
                GridViewRowInfo newRow = this.GridControl.Rows.AddNew();
                this.GridControl.CurrentRow = newRow;
                return true;
            }
            return base.ProcessKeyDown(keys);
        }
    }

As to your second question, probably you would like to implement a validation scenario. You can do that through one of the provided validation events. For more details, please refer to our product documentation.

I hope this helps. Let me know if you have any additional questions.
