Event triggers Xamdatagrid
posted

Hi

Im using MVVM model with my xamdatagrid and I have to refresh my filtered count in a label.

Ive used Interaction triggers. But dont know how to access the method RecordManager.GetFilteredInDataRecords() from my viewmodel.

In my XAML:

<i:Interaction.Triggers>
<i:EventTrigger EventName="RecordsInViewChanged" SourceName="dgRecords">
<ei:CallMethodAction MethodName="RecordsInViewChanged" TargetObject="{StaticResource lvm}"/>
</i:EventTrigger>
</i:Interaction.Triggers>

My Viewmodel:

public void RecordsInViewChanged(object sender, Infragistics.Windows.DataPresenter.Events.RecordsInViewChangedEventArgs e)
{
DependencyObject source = e.OriginalSource as DependencyObject;
if (source == null)
return;

???
}

Need to get the grid's count at any time in view model and update it in a lable

    Hi

     

    Isn't the sender the XamDataGrid ? [the original source should also be the XDG] If so you can try this:

    private void XDG_RecordsInViewChanged(object sender, Infragistics.Windows.DataPresenter.Events.RecordsInViewChangedEventArgs e)        

    {            

     var dataGrid = sender as XamDataGrid;            

     var count = dataGrid.RecordManager.GetFilteredInDataRecords().Count();

    } 

    Let me know if this is what you were looking for.

     

    Thanks,

    Slavi
