Hello,

Thank you for your post. I have been looking into it and the code you have provided and I created a sample project for you using it with the functionality you want. Basically I created the FieldLayout in the Click events of the Buttons before I changed the DataSource, so that the Fields can auto generate every time. Please let me know if this helps you or you need further assistance on this matter.

Looking forward for your reply.

Ok, below is the code.

public partial class MainWindow : Window
    {
 
        private DataTable t1 = new DataTable();
        private DataTable t2 = new DataTable();
 
        public MainWindow()
        {
            InitializeComponent();
 
            t1.Columns.Add("RecordClass", System.Type.GetType("System.String"));
            t1.Columns.Add("KeyValue", System.Type.GetType("System.String"));
            t1.Columns.Add("DataValue", System.Type.GetType("System.String"));
 
            t1.Columns.Add("Dynamic1", System.Type.GetType("System.String"));
            t1.Columns.Add("Dynamic2", System.Type.GetType("System.String"));
 
            DataRow r = t1.NewRow();
            r["RecordClass"] = "Class";
            r["KeyValue"] = "Value1";
            r["DataValue"] = "Data1";
            r["Dynamic1"] = "Dynamic1";
            r["Dynamic2"] = "Dynamic2";
 
            t1.Rows.Add(r);
            
 
            t2.Columns.Add("RecordClass", System.Type.GetType("System.String"));
            t2.Columns.Add("KeyValue", System.Type.GetType("System.String"));
            t2.Columns.Add("DataValue", System.Type.GetType("System.String"));
 
            t2.Columns.Add("Dynamic1", System.Type.GetType("System.String"));
            t2.Columns.Add("Dynamic2", System.Type.GetType("System.String"));
            t2.Columns.Add("Dynamic3", System.Type.GetType("System.String"));
 
            DataRow r1 = t2.NewRow();
            r1["RecordClass"] = "Class";
            r1["KeyValue"] = "Value1";
            r1["DataValue"] = "Data1";

            r1["Dynamic3"] = "Dynamic3";
 
            t2.Rows.Add(r1);
 
 
        }

        {
            xamDataGrid1.DataSource = t2.AsDataView();
