Thanks for the reply. I implemented this in the similar way. In the BrushConverter class I am not getting the Values I am looking for.

For each row the background of Field3 will be set depending on the values in Field1, 2 and 3. Can you help me figure out what I am doing wrong.

<Style x:Key="BackgroundColorConverter" TargetType="{x:Type igDP:CellValuePresenter}">
                            <Setter Property="Background">
                                <Setter.Value>
                                    <MultiBinding Converter="{StaticResource ColorConverter}">
                                        <Binding Path="DataItem.Value"/>
                                        <Binding Path="Field1" />
                                        <Binding Path="Field2" />
                                    </MultiBinding>
                               </Setter.Value>                               
                              
                            </Setter>
                        </Style>

<igDP:XamDataGrid.FieldLayouts>
                        <igDP:FieldLayout IsDefault="True">
                            <igDP:FieldLayout.Fields>
                                <igDP:Field Name="Field1" Label="Field1">
                                    <igDP:Field.Settings>
                                        <igDP:FieldSettings AllowEdit="False" CellHeight="30" />
                                    </igDP:Field.Settings>
                                </igDP:Field>
                                <igDP:Field Name="Field2" Label="Field2" >
                                    <igDP:Field.Settings>
                                        <igDP:FieldSettings AllowEdit="False" AllowGroupBy="True"/>
                                    </igDP:Field.Settings>
                                </igDP:Field>

                                <igDP:Field Name="Field3" Label="Field3">
                                    <igDP:Field.Settings>
                                        <igDP:FieldSettings AllowEdit="True" CellMaxWidth="150" CellValuePresenterStyle="{StaticResource BackgroundColorConverter}" />
                                    </igDP:Field.Settings>
