Hello,

Sorry, I forgot .xaml

Hello,

I have a DataGrid with a dataSource binding to a collection.

A trigger with a CellUpdated event.

The method that is called as soon as you make a change to the cell is in my ViewModel.

I want to change the color of the cell and row concerned as soon as there is change

.xaml :

<igDP:XamDataGrid Name="XamDataGridTableData" DataSource="{Binding TableData}">
     <i:Interaction.Triggers>
          <i:EventTrigger EventName="CellUpdated" x:Name="interactivityFix" SourceName="XamDataGridTableData">
               <ei:CallMethodAction x:Name="interactionsFix" MethodName="XamDataGridCellUpdated" TargetObject="{Binding}"/>
          </i:EventTrigger>
     </i:Interaction.Triggers>
</igDP:XamDataGrid>

.cs :

public void XamDataGridCellUpdated(object sender, CellUpdatedEventArgs e)
{

       var xamDataGrid = sender as XamDataGrid;

}

How could I do ?

Thanks for any thoughts.

1. Use the Tag property on the Cell, so in the CellUpdated event set Cell.Tag to a Boolean true .
2. Bind the Tag of the CellValuePresenter to a multibinding that binds to the CellValuePresenter's Field and Record
to obtain the Cell and then set the CellValuePresenter style trigger to bind to the Tag.Tag(i.e. Cell.Tag) .

<Style TargetType="{x:Type igDP:CellValuePresenter}">
            <Setter Property="Tag">
                <Setter.Value>
                    <MultiBinding Converter="{StaticResource fieldRecordToCell}">
                        <Binding RelativeSource="{RelativeSource Self}" Path="Field" />
                        <Binding RelativeSource="{RelativeSource Self}" Path="Record" />
                    </MultiBinding>
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=Tag.Tag, Converter={StaticResource keepChangedCellStyle}}" Value="True" >
                    <Setter Property="Background"  Value="Yellow"/>
                </DataTrigger>
            </Style.Triggers>
</Style>

I have attached a simple sample application, where you can test this approach.

Let me know if you have any questions.
