Hello,

It is easily supported, you just have to set the correct DataMenuItemBinding settings in your markup, and then Bind the WebDataMenu to the DataSet in the Code Behind.

Please take a look at the attached sample page.

Here is what it does:
In the CodeBehind file I am just create a DataSet with two tables and relation between them! It is important to notice that, in order for databinding to works, you ought to have Primary Key defined for every table in your data set:

protected void Page_Load(object sender, EventArgs e)
{
this.wdMain.DataSource = GetData();
this.wdMain.DataBind();
}

"rID", typeof(int));

dt.Columns.Add(

"rTexts", typeof(string));

dt.PrimaryKey =

new DataColumn[1] { dt.Columns[0] };

dt.Rows.Add(1,

"File");

dt.Rows.Add(2,

"Edit");

dt.Rows.Add(3,

"Help");

"cTexts", typeof(string));
dt2.PrimaryKey = new DataColumn[1] { dt2.Columns[0] };

dt2.Rows.Add(1, 1,

"Open");

dt2.Rows.Add(2, 1,

"Close");

dt2.Rows.Add(3, 1,

"Save");

dt2.Rows.Add(4, 1,

"Exit");

dt2.Rows.Add(5, 2,

"Cut");

dt2.Rows.Add(6, 2,

"Copy");

dt2.Rows.Add(7, 2,

"Paste");

dt2.Rows.Add(8, 2,

"Find");

dt2.Rows.Add(9, 3,

"About");

dt2.Rows.Add(10,3,

"General Help");

ds.Tables.Add(dt);

ds.Tables.Add(dt2);

ds.Relations.Add(dt.Columns[0], dt2.Columns[1]);

In the markup, I amjust defining the appropriate DataBindings:
