Tooltip doesn't appear to be showing up

[Rod]

I'm trying to make a tooltip show up on a RadGridView. I'm grouping the data by the client number. Probably the issus is that I don't understand how the tooltip will work in the RadGridView when grouping. I thought that, for example, if the user passes the mouse over a cell for the client's first name, then it would show "First Name". Am I wrong about that?  Cutting out all but the relevant XAML, here's what I've got:

<telerik:RadGridView Grid.Row="1" VerticalAlignment="Stretch" HorizontalAlignment="Left"
                     DataMember="ClientNumber" ItemsSource="{Binding}" AutoGenerateColumns="False"
                     IsReadOnly="True" ShowColumnHeaders="False" ShowGroupPanel="False"
                     IsFilteringAllowed="False" Name="grdSearchResults" AutoExpandGroups="True" FontSize="16"
                     >
  <telerik:RadGridView.Columns>
    <telerik:GridViewDataColumn UniqueName="ClientNumber" ToolTip="Client Number" />
    <telerik:GridViewDataColumn UniqueName="LastName" ToolTip="Last Name" />
    <telerik:GridViewDataColumn UniqueName="FirstNames" ToolTip="First Name"/>
    <telerik:GridViewDataColumn UniqueName="CaseNumber" ToolTip="Case Number"/>
    <telerik:GridViewDataColumn UniqueName="DateOfBirth" DataFormatString="{}{0:d}" ToolTip="DOB" />
    <telerik:GridViewDataColumn UniqueName="InterviewDate" DataFormatString="{}{0:d}" ToolTip="Interview Date" />
  </telerik:RadGridView.Columns>
    <!-- other stuff -->
 </telerik:RadGridView>

Hi,

You will need to add some actual code in order to define a tooltip.

Have you seen this tutorial? Let me know if there are problems.

I had not seen that tutorial, thank you for linking to it.

I've got a follow-up question for you, concerning the tutorial that you linked to and a training video done by John Keller (I think that is his name). In the training video John used UniqueName property of the GridViewDataColumn. In the tutorial you linked to, they use DataMemberBinding. Are they functionality the same?

Hi,

UniqueName is a very old legacy property from the dawn of RadGridView 3-4 years ago. You should use DataMemberBinding, since we have plans to obsolete the UniqueName property soon.

Your link to the tutorial is broken. Where can I find the info? : http://docs.telerik.com/devtools/wpf/api/html/gridview-how-to-create-row-tooltip.htm

Thank you
