Hello,

You could use an attached property that you can bind to the XamDataGrid, which will handle the rest automatically. Here is what I am suggesting :

 public  static  ObservableCollection <FieldLayout > GetAttachedFieldLayouts(DependencyObject  obj)

         {

             return  (ObservableCollection <FieldLayout >)obj.GetValue(AttachedFieldLayoutsProperty);

         }

         public  static  void  SetAttachedFieldLayouts(DependencyObject  obj, ObservableCollection <FieldLayout > value)

         {

             obj.SetValue(AttachedFieldLayoutsProperty, value);

         }

         public  static  readonly  DependencyProperty  AttachedFieldLayoutsProperty =

             DependencyProperty .RegisterAttached("AttachedFieldLayouts" ,

             typeof (ObservableCollection <FieldLayout >),

             typeof (FieldLayoutAdvisor ),

             new  UIPropertyMetadata (null , new  PropertyChangedCallback (OnAttachedFieldLayoutsChanged)));

         private  static  void  OnAttachedFieldLayoutsChanged(DependencyObject  o, DependencyPropertyChangedEventArgs  args)

         {

             DataPresenterBase  dpb = o as  DataPresenterBase ;

             if  (dpb != null )

             {

                 if  (dpb.FieldLayoutSettings == null )

                     dpb.FieldLayoutSettings = new  FieldLayoutSettings ();

                 dpb.FieldLayoutSettings.AutoGenerateFields = false ;

                 ObservableCollection <FieldLayout > collection = args.NewValue as  ObservableCollection <FieldLayout >;

                 if  (collection != null  && collection.Count > 0)

                 {

                     dpb.FieldLayouts.Clear();

                     foreach  (FieldLayout  fl in  collection)

                     {

                         dpb.FieldLayouts.Add(fl);

                     }

                 }

             }

         }

Then, you can bind the XamDataGrid to your DataContext :

 <igDP:XamDataGrid   

             Name="xamDataGrid1"  

             DataSource="{Binding Path=Source}" 

             fla:FieldLayoutAdvisor.AttachedFieldLayouts="{Binding FieldLayouts}"/>

I am using the XamDataGrid and have a requirement where I need to generate the columns and rows dynamically at the initialization. For this what I have done is, I have an ObservableCollection of MyGridRow in my View Model which in turn has an ObservableCollection of string. In this way, I am generating each cell for a row and multiple rows respectively. The ObservableCollection<MyGridRow> serves as the data source to the XamDataGrid. 

I implemented the FieldLayoutAdvisor as per Alex's solution and populated the field layouts. But nothing is showing up on the grid.

The code this way - 

FieldLayout headerFieldLayout = new FieldLayout();

XDocument listDoc = XDocument.Load("SecMaster.XML", LoadOptions.None);

//Get the headers of the list to create the fields in the xamDataGrid

if (listDoc.Root != null) {

                var fieldHeaders = listDoc.Root.Element("SECMASTERREC").Descendants().Select(node => node.Name.LocalName);

                if (fieldHeaders.Count() > 0)

                {

                    var fieldsList = fieldHeaders.ToList();

                    for (int index = 0; index < fieldsList.Count; index++)

                    {

                        Field headerField = new Field();

                        headerField.Name = fieldsList[index];

                        headerField.Label = fieldsList[index];

                        headerFieldLayout.Fields.Add(headerField);

                    }

                }

            }

            if (headerFieldLayout.Fields != null && headerFieldLayout.Fields.Count > 0)

            {

                if (ListsFieldLayouts == null) ListsFieldLayouts = new ObservableCollection<FieldLayout>();

                ListsFieldLayouts.Add(headerFieldLayout);

            }

            var gridCellRow = listDoc.Descendants("SECMASTERREC");

            if (gridCellRow.Count() > 0)

            {

                var gridCellRowList = gridCellRow.ToList();

                ListGridRow gridRow = new ListGridRow();

                for (int index = 0; index < gridCellRowList.Count; index++)

                {

                    gridRow.ListGridCells.Add(new ListGridCell {  GridCellValue = gridCellRowList[index].Value });

                }

                if (ListsGridSource == null) ListsGridSource = new ObservableCollection<ListGridRow>();

                ListsGridSource.Add(gridRow);

            }

Matt,

Thanks, but not at this time.  I'll try Alex's suggestion if I can ever find my way back to working on the problem that prompted my question.

The joys of frantic development!

HI,.

 I am just following up on this forum thread.

 Do you have further questions regarding this issue.
