I have aslo attached the code sample which might be useful to undestand my issues.

<i:Interaction.Triggers>
                        <i:EventTrigger EventName="CellUpdated" SourceName="xamDataGrid1">
                            <ei:CallMethodAction   MethodName="{Binding Path= xamDataGridCellUpdated}"
                        TargetObject="{Binding    ElementName=TestViewModel}"/>

                        </i:EventTrigger>

                            <ei:CallMethodAction    MethodName="{Binding Path= xamDataGridCellActivating}"
             TargetObject="{Binding    ElementName=TestViewModel}"/>

Hello,

Thank you for your post. I have been looking into it and the sample project you have attached and I suggest you use the following code for the Interaction instead of yours:

<i:Interaction.Triggers>
    <i:EventTrigger EventName="CellUpdated"  SourceName="xamDataGrid1">
        <ei:CallMethodAction MethodName="xamDataGridCellUpdated"
                                            TargetObject="{StaticResource myVM}"/>
    </i:EventTrigger>
    <i:EventTrigger EventName="CellActivating" SourceName="xamDataGrid1" >
        <ei:CallMethodAction MethodName="xamDataGridCellActivating" 
                                            TargetObject="{StaticResource myVM}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

Also you should add this to the Resources of your XamDataGrid:

<igDP:XamDataGrid.Resources>
    <local:TestViewModel x:Key="myVM"/>
</igDP:XamDataGrid.Resources>

And this namespace, too:

xmlns:local="clr-namespace:SpreadsheetFramework.Client.ViewModel"

Please let me know if this helps you or you need further assistance on this matter.

Looking forward for your reply.
