I'm using a the WPF datagrid from the Microsoft CodePlex project. I have a custom control that I want to databind to a field from the row of the datagrid. I can't for the life of me figure out how to specify a tooltip on a datagrid row.
The closest I've come is to use a RowStyle with a Setter to set the tooltip, but this only seems to work for text. When I try to put a ControlTempalte in as the Value for the ToolTip, it displays the result of calling ToString on the ControlTemplate type.
I think I need to set the "Template" property of the ToolTip, but I can't seem to figure out how to do that…
<dg:DataGrid Name="dgResults" AutoGenerateColumns="True">
<dg:DataGrid.RowStyle >
<Style TargetType="{x:Type dg:DataGridRow}">
<Setter Property="ToolTip" >
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToolTip}">
<StackPanel>
<TextBlock>txt1</TextBlock><TextBlock>txt2</TextBlock>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</dg:DataGrid.RowStyle>
</dg:DataGrid>

Figured it out... took me about 6 hours...
For some reason, I can't set the value directly using Value.Setter. If I define the content for the tooltip as a static resource though, and then set it in the Style property of the DataGrid.RowStyle it works.
So, the datagrid row style looks like:
And the resource is
