(Web menu) componentart. Menu usage

Some time ago, I wanted to use a menu function similar to the C/S architecture in a project, but I did not get it before. So Google did not find its ideal control, and the last one gave it to a friend. The effect is very good. I think a friend like me will need her to share it with you first. Here, I will introduceComponentart. MenuUsage.

Using system;
Using system. collections;
Using system. componentmodel;
Using system. Data;
Using system. drawing;
Using system. Web;
Using system. Web. sessionstate;
Using system. Web. UI;
Using system. Web. UI. webcontrols;
Using system. Web. UI. htmlcontrols;
Using system. Data. oledb;

Namespace web_menu
{
Public partial class webform2: system. Web. UI. Page
{

Private void page_load (Object sender, system. eventargs E)
{
If (! Ispostback) buildmenu ();
}

Private void buildmenu ()
{
Oledbconnection dbcon = new oledbconnection ("provider = Microsoft. Jet. oledb.4.0; Data Source =" + server. mappath ("sitemap. mdb "));
Dbcon. open ();

Oledbdataadapter adapter = new oledbdataadapter ("select * From sitemap order by nodeid", dbcon );
Dataset DS = new dataset ();
Adapter. Fill (DS );
DS. relations. Add ("noderelation", DS. Tables [0]. Columns ["nodeid"], DS. Tables [0]. Columns ["parentnodeid"]);

Foreach (datarow dbrow in DS. Tables [0]. Rows)
{
If (dbrow. isnull ("parentnodeid "))
{
Componentart. Web. UI. menuitem newitem = createitem (dbrow );
Menu1.items. Add (newitem );
Populatesubmenu (dbrow, newitem );
}
}
}

private void populatesubmenu (datarow dbrow, componentart. web. UI. menuitem item)
{< br> foreach (datarow childrow in dbrow. getchildrows ("noderelation")
{< br> componentart. web. UI. menuitem childitem = createitem (childrow);
item. items. add (childitem);
populatesubmenu (childrow, childitem);
}< BR >}

Private componentart. Web. UI. menuitem createitem (datarow dbrow)
{
Componentart. Web. UI. menuitem item = new componentart. Web. UI. menuitem ();
Item. Text = dbrow ["text"]. tostring ();
Item. navigateurl = dbrow ["navigateurl"]. tostring ();
Item. lookid = dbrow ["lookid"]. tostring ();
Item. Look. lefticonurl = dbrow ["lefticon"]. tostring ();
Item. Look. hoverlefticonurl = dbrow ["lefticonhover"]. tostring ();
Item. Look. righticonurl = dbrow ["righticon"]. tostring ();
Item. Look. hoverrighticonurl = dbrow ["righticonhover"]. tostring ();
Return item;
}
}
}
The effect is as follows:

Send it to him as needed.
