Hi,
I found the tooltip for the sfdatagrid is not working, example below, I also try it your sample project, it is not working too. It was working before, and only recently change I made was updating to version 12.3.0.29
<syncfusion:GridTextColumn HeaderText="Description" Width="200" MappingName="Description" TextWrapping="Wrap">
<syncfusion:GridTextColumn.ToolTipTemplate>
<DataTemplate>
<TextBlock Text="{Binding Description}" />
</DataTemplate>
</syncfusion:GridTextColumn.ToolTipTemplate>
</syncfusion:GridTextColumn>
Please advice me on this.
Mindy
