I find out how to selectAll text of currentcell but in TableControlCurrentCellActivated Event it still not selectAll , in TableControlCurrentCellChanged it working
This is my code
void grd_TableControlCurrentCellActivated(object sender, GridTableControlEventArgs e)
{
if (e.TableControl.CurrentCell.ColIndex == 1)
{
grd.Table.CurrentRecord.BeginEdit();
GridTextBoxCellRenderer txt = grd.TableControl.CurrentCell.Renderer as GridTextBoxCellRenderer;
txt.TextBox.SelectAll();
}
}
