Set focus to a GDBG Cell

[Osden Pereira]

Hi,

I have a GDBG where i validate the data entered by the user. I validate the data in the RowLeave event. I want to move the focus to a particular cell to prompt the user to enter the missing data. following is the code:

----------------------------------------
private void libgrid_RowLeave(object sender, GridRowEventArgs e)
{
if(e.IsAddNew == true)
{
if (this.libgrid.DataSource.ToString() == "STRV_TravelClass")
{
//Check For selected Grade
if (this.libgrid[e.RowIndex,1].Text.Trim() == "")
{
e.Cancel = true;
MessageBox.Show(this,"Please Select Employee Grade.","Staff Travel - Library Data Check",MessageBoxButtons.OK,MessageBoxIcon.Warning);
this.libgrid.ForceCurrentCellMoveTo = true;
this.libgrid.CurrentCell.MoveTo(e.RowIndex,1,GridSetCurrentCellOptions.ForceRefresh);
}

}
else if (this.libgrid.DataSource.ToString() == "STRV_TravelFares")
{
}
else if (this.libgrid.DataSource.ToString() == "")
{
}
}
}
----------------------------------------

The above code does not seem to work. it displays the message box but does not move the focus to the first cell on the row.

The simplest way to do this is to let the RowLeave finish its Cancel work (as this point the focus back to the last editing cell), and then move the currentcell. If you do not, then the RowLeave will undo your call to CurrentCell.MoveTo. You can let RowLeave finish by using a Timer.

Timer t = null;
int targetCol = -1;
private void gridDataBoundGrid1_RowLeave(object sender, GridRowEventArgs e)
{
	if(ThereIsAProblem())
	{
		MessageBox.Show( "Don''t leave");
		e.Cancel = true;
		if(t == null)
		{
			t = new Timer();
			t.Interval = 30;
			t.Tick += new EventHandler(t_Tick);
		}
		targetCol = 3;//where you want to go
		t.Start();
	}
}
private void t_Tick(object sender, EventArgs e)
{
	t.Stop();
	t.Tick -= new EventHandler(t_Tick);
	t.Dispose();
	t = null;
	GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
	cc.MoveTo(cc.RowIndex, targetCol);
}
