Hello,

Yes it is possible to bind UltraGrid to such way, so you should set as DataSource  of the grid your dataset and also you should specify DataMember of the grid to the parent table of the relation which you want to display. Here is simple code snipped that creates dataset with 4 tables and two grids that display relations of the dataset:

DataSet ds = new DataSet();

            DataTable t1 = ds.Tables.Add("table1");

            t1.Columns.Add("id", typeof(int)).AutoIncrement = true;

            t1.Columns.Add("Text", typeof(string)).Expression = "'table1 row'+[id]";

            DataTable t2 = ds.Tables.Add("table2");

            t2.Columns.Add("id", typeof(int)).AutoIncrement = true;

            t2.Columns.Add("pid", typeof(int));

            t2.Columns.Add("Text", typeof(string)).Expression = "'table2 row'+[id]";

            DataTable t3 = ds.Tables.Add("table3");

            t3.Columns.Add("id", typeof(int)).AutoIncrement = true;

            t3.Columns.Add("Text", typeof(string)).Expression = "'table3 row'+[id]";

            DataTable t4 = ds.Tables.Add("table4");

            t4.Columns.Add("id", typeof(int)).AutoIncrement = true;

            t4.Columns.Add("pid", typeof(int));

            t4.Columns.Add("Text", typeof(string)).Expression = "'table4 row'+[id]";

            for (int i = 0; i < 5; i++)

            {

                DataRow row1 = t1.Rows.Add();

                DataRow row3 = t3.Rows.Add();

                for (int j = 0; j < 5; j++)

                {

                    t2.Rows.Add(null, row1["id"]);

                    t4.Rows.Add(null, row3["id"]);

                }

            }

            ds.Relations.Add("t1 to t2", t1.Columns["id"], t2.Columns["pid"]);

            ds.Relations.Add("t3 to t4", t3.Columns["id"], t4.Columns["pid"]);

            ultraGrid1.DataSource = ds;

            ultraGrid1.DataMember = "table1";

            ultraGrid2.DataSource = ds;

            ultraGrid2.DataMember = "table3";
