GridGroupingControl Cell Tooltips

[David Llewellyn]

Hello,

I am trying to set the cells (of a GridGroupingControl) tooltip in PrepareViewStyleInfo, to the same value that
is displayed in that cell.

Something like this :-

private void TableControl_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
GridRecordRow rec = this.gridcontrol.Table.DisplayElements[e.RowIndex] as GridRecordRow;
if(rec != null)
{
DataRowView colorrow = rec.GetData() as DataRowView;
try
{
if ((e.ColIndex > 3) && (e.ColIndex < 7)) e.Style.CellTipText = colorrow[e.ColIndex].ToString();
}
catch
{
}
}
}

This method REALLY slows down the grouping grid. Do you know of a better way of setting the tooltips of the cells? Can this be done when the grid is being loaded, instead of setting the cell tooltips value at run-time?

Thanks.
David.

There is no way to set the CellTipText to the Text except through an event, either TableControlPrepareViewStyleInfo or QueryCellStyleInfo.

Try this code:

private void gridGroupingControl1_TableControlPrepareViewStyleInfo(object sender, GridTableControlPrepareViewStyleInfoEventArgs e)
{
	if ((e.Inner.ColIndex > 3) && (e.Inner.ColIndex < 7))
	{
		e.Inner.Style.CellTipText = e.Inner.Style.Text;
	}
}

Thanks Clay,

That makes the program run much faster.

Cheers.
