Add row on key press

We are trying to provide a feature to add a new row by hitting the Tab or F9 key by trapping the Key down event. This event doesn’t get trigged when the user is editing a value on a particular column. Is there a way we can implement this ? Note: We are trying to avoid using the Key press event of the column as they would be triggered for all the every key which might affect the performance of the application. Also, there is a constraint in the application that data in all the previous row should be entered before adding the new row.

You can derive the grid and override ProcessCmdKey to catch these keys and add a row.

public class MyGridDataBoundGrid : GridDataBoundGrid
{
	protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
	{
		if((0 != (keyData & Keys.Tab)) || (0 != (keyData & Keys.F9)))
		{
			  this.Binder.AddNew();
			 return true; //ignore the key
		}
		return base.ProcessCmdKey (ref msg, keyData);
	}
}
