    [CLOSED] Adding menu items to button group dynamically in a direct event..

    Hi,

    I'm trying to add menu items dynamically to button group, when user selects one of the item in a SelectBox. However, i do not see any menu item in the button group. Looks like, it is not getting rendered after adding items to the menu.

    Here is the sample code, which i'm calling in direct event of SelectBox:

     private void BindMenuItems()
    {
        for (int i = 0; i < 5; i++)
        {
            Ext.Net.MenuItem menuItem = new Ext.Net.MenuItem();
            menuItem.ID = "item" + i.ToString();
            menuItem.Text = "item " + i.ToString();
            this.btnMenu.Items.Add(menuItem);
        }      
        
    }
    Appreciate, if you can suggest the right way to achieve this.

    Thanks.

    Hi,

    Changing Items collection during DirectEvent/DirectMethod doesn't affect on client automatically. You should render controls.

    In your case you could call the Render method for each MenuItem.

    Example
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void AddItems(object sender, DirectEventArgs e)
    {
        Ext.Net.MenuItem mi1 = new Ext.Net.MenuItem("New item 1");
        Ext.Net.MenuItem mi2 = new Ext.Net.MenuItem("New item 2");
        this.Menu1.Items.Add(mi1);
        mi1.Render();
        this.Menu1.Items.Add(mi2);
        mi2.Render();
    }
</script>

<body>
    <ext:ResourceManager runat="server" />

    <ext:Button runat="server" Text="Menu">
        <Menu>
            <ext:Menu ID="Menu1" runat="server">
                <Items>
                    <ext:MenuItem runat="server" Text="Item 1" />
                </Items>
            </ext:Menu>
        </Menu>
    </ext:Button>

    <ext:Button runat="server" Text="Add items" OnDirectClick="AddItems" />
</body>
</html>
