I want to use TreeListView and use DataTable object from the datatable Project provided by telerik .
I want to have nested items that means 1 parent can have multiple childs.If i am binding with datatable currently it is showing all items in individual row.
How to achieve parent child kind of relationship using datatable object.
Please suggest.
Regards,
Rajesh

You need to have your child data in some of the table columns and assign child table binding to this column.

Dear Vlad,
I tried using the way you have suggested but somehow it didnot work for me.
Below is the code snippet.
DataTable dt = new DataTable();
dt.Columns.Add(
new DataColumn() { ColumnName = "col1", DataType = typeof(string) });
dt.Columns.Add(
new DataColumn() { ColumnName = "col2", DataType = typeof(DataTable) });
DataRow dr = dt.NewRow();
dr[
"col1"] = "34563456";
dt.Rows.Add(dr);
DataTable dt1 = new DataTable();
dt1.Columns.Add(
new DataColumn() { ColumnName = "col1", DataType = typeof(string) });
dt1.Columns.Add(
new DataColumn() { ColumnName = "col2", DataType = typeof(DataTable) });
DataRow dr1 = dt1.NewRow();
dr1[
"col1"] = "34563456";
dr[
"col2"] = dt1;
RadTreeListView1.ItemsSource = dt;
TreeListViewTableDefinition tb = new TreeListViewTableDefinition();
tb.ItemsSource =
new Binding("col2");
RadTreeListView1.ChildTableDefinitions.Add(tb);
Let me know if i am doing any thing wrong here.
