CellClick and Keys navigation

[superold]

hi

i wonder what the best way to implement CellClick (which I use as a RowClick) would be when using keys for navigation. In a sence it would be optimal if the up/down/left/right keys would trigger CellClick.. 

thanks

Hello Jorge,

First, i should start by saying that if you just want to be notified when the current row is changed you can just use that event (CurrentRowChanging and CurrentRowChanged), but if you prefer using the CellClick event, there are a couple of ways of doing this, from which the easiest one is to create a custom grid, inheriting from RadGridView, and just override the OnKeyDown event, like this:

public class CustomGrid : RadGridView
    {
        public override string ThemeClassName
        {
            get { return typeof(RadGridView).FullName; }
        }

        protected override void OnKeyDown(KeyEventArgs e)
        {
            base.OnKeyDown(e);

            if (this.CurrentCell != null && this.CurrentCell.RowIndex != -1 && this.CurrentCell.ColumnIndex != -1 &&
                 (e.KeyCode == Keys.Left || e.KeyCode == Keys.Right || e.KeyCode == Keys.Up || e.KeyCode == Keys.Down))
            {
                OnCellClick(this.CurrentCell, new GridViewCellEventArgs(CurrentCell.RowInfo, CurrentCell.ColumnInfo));
            }
        }

There is also another more complex solution in which you can create a new GridBehavior override there the ProcessKey event, and get the next cell there, but the problem with this is that you cannot call any event from the grid behavior...

If you need anything else or if you want to try doing things with the grid behavior please let me know and i will add that solution also, but like i told you, i haven't found a way of calling any grid events from the grid behavior...

Hope this helps,
