Need to populate a Datagrid in UWP with a Datatable. I could display the contents by following: https://stackoverflow.com/a/53767049/12053338

However, I am unable to edit the datagrid.

How do I make the Datagrid editable? (tired setting IsReadOnly to false).

Thanks

XAML

         <controls:DataGrid
                        x:Name="grid" 
                        IsReadOnly="False"
                        VerticalAlignment="Stretch" 
                        HorizontalAlignment="Stretch"
                        GridLinesVisibility="All">

        </controls:DataGrid>

C#

            //Datatable
            var table = new DataTable("Students");
            table.Columns.Add(new DataColumn() { ColumnName = "Name", DataType = typeof(string)});
            table.Columns.Add(new DataColumn() { ColumnName = "Id", DataType = typeof(string)});

            //Add a row
            table.Rows.Add("Akinator","1");

          //Conversion of datatable to datagrid itemsource
          for (int i = 0; i < table.Columns.Count; i  )
            {
                grid.Columns.Add(new DataGridTextColumn()
                {
                    Header = table.Columns[i].ColumnName,
                    Binding = new Binding { Path = new PropertyPath("["   i.ToString()   "]"), Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }

                });
            }
            var collection = new ObservableCollection<object>();
            foreach (DataRow row in table.Rows)
            {
                if (row.ItemArray.Length > 0)
                    collection.Add(row.ItemArray);


            }
            grid.ItemsSource = collection;

*Usage of data table cannot be substituted in this particular case.

I have figured out the solution to this, Set IsReadonly to false while creating the columns

 //Conversion of datatable to datagrid itemsource
      for (int i = 0; i < table.Columns.Count; i  )
        {
            grid.Columns.Add(new DataGridTextColumn()
            {
                Header = table.Columns[i].ColumnName,
                Binding = new Binding { Path = new PropertyPath("["   i.ToString()   "]"), Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged },
                IsReadOnly = false //ADD THIS TO MAKE THE DATAGRID EDITABLE

            });
        }
        var collection = new ObservableCollection<object>();
        foreach (DataRow row in table.Rows)
        {
            if (row.ItemArray.Length > 0)
                collection.Add(row.ItemArray);


        }
        grid.ItemsSource = collection;
