RadMenu with databinding and dynamic templates

[Carlos Amigo]

Hi guys. I need to implement this ajax funtionallity.
I've a RadMenu databinded with SQL Server.
When I put the mouse pointer over the last menuitem of one hierarchy, I need to pass a custom attribute with a URL to a WCF service and populate a Menu Template with all data returned, (this comes from a document library of sharepoint).
How i can to do this?

Thanks

Charly

Hello Carlos,

There is an online demo with web services:

I hope it helps you get started.

Peter: Thank you. Now I've a new chalenge. I'm a table in SQL with the hierarchy of the items, (with ParentId included) databinded to a RadMenu, and I need to show the last two hierarchies of the table, (or menu) in a template menu.
Is this possible?

TIA

Hello Carlos,

Unfortunately, this scenario is not supported by RadMenu.

Add the "OnDataBound" event on aspx page where we can hide the items on the level 1 (sublevels become autommatically hidden) and add a new item template for each level 0 item. In this example, the template has a RadSiteMap with the menu items of level 1 and level 2.

    protected void RadMenu1_DataBound(object sender, EventArgs e)
    {
        try
        {
            foreach (RadMenuItem item in ((RadMenu)sender).GetAllItems())
            {
                if (item.Level == 0)
                {
                    item.PostBack = false;


                    RadMenuItem siteMap = new RadMenuItem();
                    siteMap.Text = "";
                    siteMap.ItemTemplate = new MenuTemplate();
                    item.Items.Add(siteMap);
                }
                else
                {
                    item.Visible = false;
                }
            }


            foreach (RadMenuItem item in ((RadMenu)sender).GetAllItems())
            {
                if ((item.Level == 1) && (item.Text == ""))
                {
                    item.DataBind();
                }
            }
        }
        catch { }
        finally { }
    }





class MenuTemplate : ITemplate
{
    public void InstantiateIn(Control container)
    {
        RadSiteMap radSiteMap1 = new RadSiteMap();
        radSiteMap1.ID = "RadSiteMap1";
        radSiteMap1.Skin = "Default";
        radSiteMap1.Width = Unit.Pixel(450);
        SiteMapLevelSetting smls = new SiteMapLevelSetting(0);
        smls.ListLayout.RepeatColumns = 1;
        smls.ListLayout.RepeatDirection = SiteMapRepeatDirection.Horizontal;
        radSiteMap1.LevelSettings.Add(smls);
        SiteMapLevelSetting smls1 = new SiteMapLevelSetting(1);
        smls1.ListLayout.RepeatColumns = 4;
        smls1.ListLayout.RepeatDirection = SiteMapRepeatDirection.Horizontal;
        radSiteMap1.LevelSettings.Add(smls1);
        radSiteMap1.DataBinding += new EventHandler(radSiteMap1_DataBinding);
        container.Controls.Add(radSiteMap1);
    }


    private void radSiteMap1_DataBinding(object sender, EventArgs e)
    {
        RadSiteMap target = (RadSiteMap)sender;
        RadMenuItem item = (RadMenuItem)target.BindingContainer;
        RadMenuItem root = ((RadMenuItem)item.Parent);


        for (int i = 0; i < root.Items.Count; i++)
        {
            if (root.Items[i].Text != "")
            {
                RadSiteMapNode nodeParent = new RadSiteMapNode(root.Items[i].Text, "");
                nodeParent.Enabled = false;
                target.Nodes.Add(nodeParent);


                for (int j = 0; j < root.Items[i].Items.Count; j++)
                {
                    nodeParent.Nodes.Add(new RadSiteMapNode(root.Items[i].Items[j].Text, root.Items[i].Items[j].NavigateUrl));
                }
            }
        }
    }
