HI,

 Here is the xaml:

  <Grid Name="layoutroot">   

      <Grid.Resources>

            <Style x:Key="columnstyle" TargetType="{x:Type igDP:CellValuePresenter}">

             <Setter Property="ToolTip" Value="{Binding Path=DataItem.ISCHECKED}"/>  

           </Style>   

       </Grid.Resources>  

            <igDP:XamDataGrid    Name="xgrid1"   DataSource="{Binding People}">

               <igDP:XamDataGrid.FieldLayoutSettings>   

                 <igDP:FieldLayoutSettings AutoGenerateFields="False" />

            </igDP:XamDataGrid.FieldLayoutSettings>   

                     <igDP:XamDataGrid.FieldLayouts>   

              <igDP:FieldLayout>   

                  <igDP:Field Name="Name"/>     

                <igDP:Field Name="Age">   

                      <igDP:Field.Settings>

                            <igDP:FieldSettings CellValuePresenterStyle="{StaticResource columnstyle}"/>    

                     </igDP:Field.Settings>

                     </igDP:Field>  

               </igDP:FieldLayout>     

        </igDP:XamDataGrid.FieldLayouts>  

                   </igDP:XamDataGrid>
