Tooltips for indivual cells of a DataGrid

Just recently,  I have been faced with the question on how to add cell dependent tooltips to individual cells of a DataGrid in Silverlight. If you generate the columns by yourself, the task is straight forward by using the appropriate data template for the cell. Something like this:

<Data:DataGrid>
   <Data:DataGrid.Columns>
      <Data:DataGridTemplateColumn>
         <Data:DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
               <TextBlock  Text="{Binding ColumnProperty}"
                    ToolTipService.ToolTip="{Binding ColumnProperty}"/>
            </DataTemplate>
         </Data:DataGridTemplateColumn.CellTemplate>
      </Data:DataGridTemplateColumn>
   </Data:DataGrid.Columns>
</Data:DataGrid>

However, if you let the columns be autogenerated by the grid, things are not so straight forward anymore. Tooltips for indivual cells of a DataGrid weiterlesen
