HI ,

 Create a style targeting the LabelPresenter and set the FieldSetting's LabelPresenterStyle to that style.

 Here are the code snippets:

<Grid.Resources>  

           <Style x:Key="lbstyle" TargetType="{x:Type igDP:LabelPresenter}"> 

          <Setter Property="Background" Value="red"/>

            </Style> </Grid.Resources>

 <igDP:XamDataGrid.FieldLayouts>  

               <igDP:FieldLayout>

                    <igDP:FieldLayout.Fields>

                         <igDP:Field Name="Name">  

                           <igDP:Field.Settings>

                                 <igDP:FieldSettings LabelPresenterStyle="{StaticResource lbstyle}"/>  

                           </igDP:Field.Settings>  

                       </igDP:Field>  

                       <igDP:Field Name="Age"/>   

                  </igDP:FieldLayout.Fields>

                </igDP:FieldLayout>

 </igDP:XamDataGrid.FieldLayouts>
