Good day,

Is it possible to bind a the xamdatagrid to a list of Dictionary Items and display it's values?

Let me explain. I have a REST call that returns a list of records, the columns are dynamic, ie depending on the call structure the call can return list of record with 5 columns or another call can return a list of records with 10 columns and so on.

So I want to bind the result to a xamadatagrid. I currently get the result back and the xamdatagrid display the number of rows, but each row /column has no value.

From my understanding, for xamarin forms, that if you put the columns names in brackets, [], it will map the key field of the dictionary to the column name and the value to the actual value, it is working like that on listviews and other view bindings. I have also seen a sample on your support forums, but it was silverlight, that did the same thing.  So for the PropertyPath value of a columns that I add I set to the ColumnName in brackets when I know that I do not the actual record layout, see code snippet below.

I condensed the code snippet to try and explain what I am trying todo:

        /// <summary>
        /// Return a list of records from json content
        /// </summary>
        /// <param name="content"></param>
        /// <returns>List of Records in KeyValue pairs: Key = ColumnName and Value = ColumnValue </returns>
        protected override ObservableRangeCollection<Dictionary<string, object>> DeserializeObject(string content)
        {
            var result = JsonConvert.DeserializeObject<ObservableRangeCollection<Dictionary<string, object>>>(content);
            return result;
        }

      private void ViewModelOnCollectionChanged(object o, ItemsEventArgs itemsEventArgs)
        {
            try
            {

                var columns = ViewModel.ColumnsTypes; // get columns names
                CreateGridColumns(columns); // create columns for grid
                EntityGrid.ItemsSource = DeserializeObject(ViewModel.FormData); // get records
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine(ex.Message);
            }
        }

        private void CreateGridColumns(List<GridColumnsEntity> columns)
        {

            var grid = EntityGrid;
            if (columns != null)
            {
                grid.AutoGenerateColumns = false;
                grid.DefaultColumnWidth = ColumnWidth.Default;
                grid.Columns?.Clear();
                foreach (var column in columns)
                {                    
                    switch ((FieldTypes) column.TypeID)
                    {                        
                        case FieldTypes.Number:
                        {
                            grid.Columns?.Add(new NumericColumn
                            {
                                PropertyPath = ViewModel.IsColumnNameNotKnown ? "[" + ClientHelper.ToCamelCase(columnName) + "]" : columnName,
                                HeaderText = column.Description,
                            });
                            break;
                        }
                        case FieldTypes.Currency:
                        {
                            grid.Columns?.Add(new NumericColumn
                            {
                                PropertyPath = ViewModel.IsColumnNameNotKnown ? "[" + ClientHelper.ToCamelCase(columnName) + "]" : columnName,
                                HeaderText = column.Description,
                                FormatString = "C"
                            });
                            break;
                        }
                        case FieldTypes.AppointmentDate:
                        case FieldTypes.DateTime:
                        case FieldTypes.Date:
                            {
                            if (!Enum.TryParse(ClientHelper.DateFormat, out DateTimeFormats format))
                            {
                                format = DateTimeFormats.DateShort;
                            }

                                    var dateCol = new DateTimeColumn
                                    {
