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.

Hi Stefan,

Thank you very much for prompt reply.

I have tried with this statice resouces but in that case my Viewmodel Constructor is getting called twice.

In our scenario , we are actully adding differenct usercontrol(view) based on Ribbon control button click event into content place holder and if you check the MainwindowResource file , there we have provide the databinding between the view and viewmodel. If I remove that binding and kept only your statice binding it will not getting display.

So, thats issues i was facing right now. Kindly suggest solution for this.

Looking forward for your reply.

Thx,

Jay

Hello Jay,

I have been looking into your requirement and in that case I suggest you use the following code:

<igDP:XamDataGrid  Grid.Row="1" AutoFit="False" MaxHeight ="660"   Width="545" DataSource="{Binding Path=EmpList,Mode=TwoWay}" 
                    DataContext="{Binding  UpdateSourceTrigger=PropertyChanged}"  
                    HorizontalAlignment="Stretch" x:Name="xamDataGrid1" VerticalAlignment="Stretch" BorderBrush="Black"
                    Theme="RoyaleStrong" BorderThickness="1" Margin="10,10,10,10" Height="260" >
    <igDP:XamDataGrid.FieldLayoutSettings>
        <igDP:FieldLayoutSettings   HighlightAlternateRecords="True" AutoGenerateFields="True" AllowAddNew="False"></igDP:FieldLayoutSettings>
    </igDP:XamDataGrid.FieldLayoutSettings>
    <igDP:XamDataGrid.FieldSettings  >
        <igDP:FieldSettings AllowEdit="True"   AllowGroupBy="False" AllowRecordFiltering="True"></igDP:FieldSettings>
    </igDP:XamDataGrid.FieldSettings>                    
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="CellUpdated"  SourceName="xamDataGrid1">
            <ei:CallMethodAction MethodName="xamDataGridCellUpdated" TargetObject="{Binding}"/>    
        </i:EventTrigger>
        <i:EventTrigger EventName="CellActivating"  SourceName="xamDataGrid1">
            <ei:CallMethodAction MethodName="xamDataGridCellActivating" TargetObject="{Binding}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
</igDP:XamDataGrid>

Basically I changed the DataContext of the XamDataGrid and its DataSource binding, so that I can use the DataContext in the EventTriggers. Pease let me know if this helps you or you need further assistance on this matter.

Looking forward for your reply.
