I guess you can store any kind of "object" to a column in a data table. I tried to store Nodes collection in the following example. In the same fashin, you can either store XML as String of Stream.

DataTable loDT  = new DataTable();
DataColumn loCL = new DataColumn();
loDT.Columns.Add(loCL);
DataRow	 loROW = loDT.NewRow();
loROW[0] = this.treeView1.Nodes;
loDT.Rows.Add(loROW);
