In the code behind within the button click delegate you can create a new Menu & MenuItem and simple add it to a control.

eg.
protected void Button1_Click(object sender, EventArgs e)
{
Menu newMenu = new Menu();
this.form1.Controls.Add(newMenu);
MenuItem newItem = new MenuItem("test");
newMenu.Items.Add(newItem);
}

Not sure if your requirements where this simple or not.

Hi

What I'm tring to do is, On Button Click I'm Creating the Menu with three Menu Items, under that One MultiView Container and three View control inside that MultiView Container. In Each view I have added one textbox.
What i want is when i click menu item 1 it should show view 1, when click menu item 2 it should view 2,... correspondingly..

The menu item event is not firing ... Please guide me and check my code ... do i going in the right direction?
Typically wht i'm tring to do is creating Tab Control kind of display at runtime...

Please help on this.

    MultiView viewContainer;
    Panel Panel1 = new Panel();
 
protected void Button2_Click(object sender, EventArgs e)
    {
        Menu newMenu = new Menu();
        this.form1.Controls.Add(newMenu);
 
        MenuItem newItem1 = new MenuItem("Tab1");
        newItem1.Value = "1Tab";
        newMenu.Items.Add(newItem1);
 
        MenuItem newItem2 = new MenuItem("Tab2");
        newItem2.Value = "2Tab";
        newMenu.Items.Add(newItem2);
 
        MenuItem newItem3 = new MenuItem("Tab3");
        newItem3.Value = "3Tab";
        newMenu.Items.Add(newItem3);
 
        newMenu.Orientation = Orientation.Horizontal;
        viewContainer = new MultiView();
 
        for (int i = 0; i < 3; i++)
        {
            View vw = new View();
            vw.ID = "Tab" + i.ToString() + 1;
 
            TextBox txtBox = new TextBox();
            txtBox.ID = "txtBox" + vw.ID;
            txtBox.Text ="View" + i.ToString();
 
            vw.Controls.Add(txtBox);
            viewContainer.Views.Add(vw);
        }
        viewContainer.ActiveViewIndex = 0;
        Panel1.Controls.Add(viewContainer);
        Page.Form.Controls.Add(Panel1);
    }
 
protected void newMenu_MenuItemClick(Object sender, System.Web.UI.WebControls.MenuEventArgs e)
    {
        switch (e.Item.Value)
        {
            case "1Tab":
                return;
 
            case "2Tab":
                return;
 
            case "3Tab":
                return;
        }
    }

I couldn't see this in your code; don't forget to assign your event handler to the menu.

newMenu.MenuItemClick += new MenuEventHandler(newMenu_MenuItemClick);

by: vivekthangaswamyPosted on 2008-05-15 at 21:17:56ID: 21579961

After adding also its not firing ?
can you send me the code which worked for you

by: theplonkPosted on 2008-05-15 at 22:42:04ID: 21580259

Here is a messy sample that worked for me. You will need to clean it up and shape it to what you want. Should give you an idea.

private MultiView multiview = new MultiView();
        private View[] view = new View[3];
        private TextBox[] textBox = new TextBox[3];
 
        protected void Page_Load(object sender, EventArgs e)
        {
            MenuItem newMenuItem = new MenuItem("View1");
            MenuItem newMenuItem2 = new MenuItem("View2");
            MenuItem newMenuItem3 = new MenuItem("View3"); 
            Menu menu = new Menu();
            menu.Items.Add(newMenuItem);
            menu.Items.Add(newMenuItem2);
            menu.Items.Add(newMenuItem3); 
            menu.MenuItemClick += new MenuEventHandler(menu_MenuItemClick);
            this.form1.Controls.Add(menu);
 
            for (int i = 0; i < 3; i++)
            {
                textBox[i] = new TextBox();
                textBox[i].Text = "View" + i;
                view[i] = new View();
                view[i].Controls.Add(textBox[i]);
                multiview.Views.Add(view[i]);
            }
            this.form1.Controls.Add(multiview);
 
        }
 
        void menu_MenuItemClick(object sender, MenuEventArgs e)
        {
            if (e.Item.Value.ToString() == "View1"){ 
                    this.multiview.ActiveViewIndex = 0;}
            if (e.Item.Value.ToString() == "View2") {
                    this.multiview.ActiveViewIndex = 1;}
            if (e.Item.Value.ToString() == "View3") {
                    this.multiview.ActiveViewIndex = 2;}
        }
