Currently the words: Row, Column and Value are not localizable in the ScreenTip.
Currently they can be localized as follows:
void radPivotGrid1_ScreenTipNeeded(object sender, Telerik.WinControls.ScreenTipNeededEventArgs e)
{
PivotCellElement cell = e.Item as PivotCellElement;
if (cell == null || cell.ScreenTip == null)
{
return;
}
RadOffice2007ScreenTipElement screenTip = cell.ScreenTip asRadOffice2007ScreenTipElement;
screenTip.MainTextLabel.Text = screenTip.MainTextLabel.Text
.Replace("Value:", "ChangedValue:")
.Replace("Row:", "ChangedRow:")
.Replace("Column:", "ReplacedColumn:");
}
