How to Autosort a FeatureDataGrid Column by OBJECTID

MattMiley

Does anyone know how to Autosort a FeatureDataGrid OBJECTID Column?

I figured out how to sort a datagrid by an attribute using the following code

 FeatureSet featureSet = args.FeatureSet;
           
            if (featureSet != null && featureSet.Features.Count > 0)
            {
               
                PagedCollectionView itemListView = new PagedCollectionView(featureSet);
                itemListView.SortDescriptions.Add(new System.ComponentModel.SortDescription("Attributes[JobID]", System.ComponentModel.ListSortDirection.Ascending));

                foreach (Graphic graphic in itemListView)
                {
                    PatchedMainReportListbox.Items.Add("Job ID: " + graphic.Attributes["JobID"].ToString() + ",   Main Number: " + graphic.Attributes["MainNumber"].ToString() + ",   Date: " + graphic.Attributes["DateTime"].ToString());
                }
            }

I just don't know how to do something simulair with a featuredatagrid thats binded to a map and feature layer in the xaml.

You can use PagedCollectionView.SortDescription as well and set it on event AutoGeneratingColumns.

Something like:

MyDataGrid.AutoGeneratingColumn += (e, args) =>
{
    if (args.PropertyName.Equals("OBJECTID"))
    {
        var pagedCollectionView = MyDataGrid.ItemsSource as PagedCollectionView;
        if (pagedCollectionView != null)
            pagedCollectionView.SortDescriptions.Add(new SortDescription(args.PropertyName, ListSortDirection.Ascending));
    }
};
