The formatting got screwed here is better version.

private void LoadMenuItems()

{

DataSet dsMenuItems = new DataSet();

try

{

//this method gets you the 2 datatables in the dataset

GetMenu(ref dsMenuItems);

dsMenuItems.DataSetName = "Menu";

dsMenuItems.Tables[0].TableName = "MainMenu";

dsMenuItems.Tables[1].TableName = "SubMenu";

dsMenuItems.Relations.Add("RELATION", dsMenuItems.Tables[0].Columns["MAINMENUITEMID"],

dsMenuItems.Tables[1].Columns["MAINMENUITEMID"], true);

//populate the menu here

if (dsMenuItems != null)

{

UltraWebMenu1.DataSource = dsMenuItems;//.Tables[0].DefaultView;

//UltraWebMenu1.Levels[0].TargetUrlName = "NAVIGATIONURL";

UltraWebMenu1.Levels[0].ColumnName = "MAINMENUITEMNAME";

UltraWebMenu1.Levels[0].LevelKeyField = "MAINMENUITEMID";

UltraWebMenu1.Levels[0].RelationName = "RELATION";

UltraWebMenu1.Levels[1].TargetUrlName = "NAVIGATIONURL";

UltraWebMenu1.Levels[1].ColumnName = "SUBMENUITEMNAME";

UltraWebMenu1.Levels[1].LevelKeyField = "SUBMENUITEMID";

UltraWebMenu1.DataMember = dsMenuItems.Tables[0].TableName;

UltraWebMenu1.DataBind();

}

}

catch (Exception ex)

{

}

}

Here it is if you want to bind a dataset.

DataSet

dsMenuItems = new DataSet();

try{

//this method gets you the 2 datatables in the dataset

ref dsMenuItems);

dsMenuItems.DataSetName =

"Menu";

dsMenuItems.Tables[0].TableName =

"MainMenu";

dsMenuItems.Tables[1].TableName =

"SubMenu";

dsMenuItems.Relations.Add(

"RELATION", dsMenuItems.Tables[0].Columns["MAINMENUITEMID"], sMenuItems.Tables[1].Columns["MAINMENUITEMID"], true);

//populate the menu here

if (dsMenuItems != null)

{

UltraWebMenu1.DataSource = dsMenuItems;

//UltraWebMenu1.Levels[0].TargetUrlName = "NAVIGATIONURL";

UltraWebMenu1.Levels[0].ColumnName = "MAINMENUITEMNAME";

UltraWebMenu1.Levels[0].LevelKeyField =

"MAINMENUITEMID";

UltraWebMenu1.Levels[0].RelationName =

"RELATION";

UltraWebMenu1.Levels[1].TargetUrlName =

"NAVIGATIONURL";

UltraWebMenu1.Levels[1].ColumnName =

"SUBMENUITEMNAME";

UltraWebMenu1.Levels[1].LevelKeyField =

"SUBMENUITEMID";

UltraWebMenu1.DataMember = dsMenuItems.Tables[0].TableName;

UltraWebMenu1.DataBind();

}

}

{

}

 i have been used binding of UltraWebTree for Menu and it work fine.

here is my DataTable with columns "ID - ParentID - Name" and a Relations as

DataRelation dr = new DataRelation("re", ds.Tables[0].Columns["ID"], ds.Tables[0].Columns["ParentID"], false);

and this is code for binding:

           //assign the datasource
            DataView dv = ds.Tables[0].DefaultView;
            dv.RowFilter = "ParentID=0";
            this.UltraWebMenu1.DataSource = dv;

            //set up the levels to use the relation
            for (int i = 0; i < 50; i++)
            {
                this.UltraWebMenu1.Levels[i].ColumnName = "Name";
                this.UltraWebMenu1.Levels[i].LevelImage = "../../../ig_common/images/dir.png";
                this.UltraWebMenu1.Levels[i].RelationName = "r1";
                this.UltraWebMenu1.Levels[i].LevelKeyField = "ID";
            }

            //databind
            this.UltraWebMenu1.DataBind();
            UltraWebMenu1.WebMenuTarget = Infragistics.WebUI.UltraWebNavigator.WebMenuTarget.HorizontalMenu;
