                                  • I also want to have tooltip for each cell in our group. In the datasource, there are two columns: Name and Category. I would like to show Name in one column, and show Category as tooltip. Follow your sample code, I have the following definition:

                                    <dxg:GridColumn FieldName="Name" Header="Name" ReadOnly="True">



                                    <dxe:TextEdit x:Name="PART_Editor">



                                    <TextBlock Text="{Binding Path=RowData.Row.Category, Mode=OneWay}" />







                                    However, though the column shows Name, we keep getting the error: 'ToolTip' cannot have a logical or visual parent. Any suggestion. Note that we use DevExpress.Wpf.Grid.v9.3 (version in Visual Studio 2008. Thanks.

                                Hello Andy,

                                Thank you for providing the sample code.

                                There is no need to put a TextBlock element in the ToolTipService.ToolTip. You can bind the ToolTip directly to the Category value. Here is some sample code:

                                <dxe:TextEdit Name="PART_Editor"> <ToolTipService.ToolTip> <Binding Path="Data.Category"/> </ToolTipService.ToolTip> </dxe:TextEdit>

                                I am attaching a small sample project, illustrating this approach. Please try it on your side and let us know how it goes.

                                  Is there a way to have more than one information, for example Data.Name, Data.Address, etc... in the binding path?

                                  I need additional time to research why you get an issue if you use the tooltip like in your first message. As a workaround, you can execute the following code:

                                  <dxg:GridColumn FieldName="Name"> <dxg:GridColumn.CellTemplate> <DataTemplate> <ContentControl> <ContentControl.ToolTip> <StackPanel> <TextBlock Text="{Binding Path=Data.Category, Mode=OneWay}"/> <TextBlock Text="{Binding Path=Data.Name, Mode=OneWay}"/> </StackPanel> </ContentControl.ToolTip> <dxe:TextEdit Name="PART_Editor"> </dxe:TextEdit> </ContentControl> </DataTemplate> </dxg:GridColumn.CellTemplate> </dxg:GridColumn>

                                  We have researched the issue and found that it was a bug in version 9.3. We fixed it in version 11.1. If you wish to use 9.3.7, use my workaround; alternatively, you can update our controls to the latest version.
