e.Item.Level bug?

[Tim]

Hi I'm using the beta version of the menu and I'm getting a "{"Unable to cast object of type 'Telerik.Web.UI.RadMenu' to type 'Telerik.Web.UI.RadMenuItem'."}" error whenever I try to access the Level property. I don't know where to reprot beta issues, so here it is. This is what my code looks like...

If

Not e.Item.Level = 0 Then

No way it's me right?

Hello Tim,

Unfortunately, we were not able to reproduce the bug locally. Can you please send us a simple page that demonstrates the issue?

Best wishes,

I'm getting the same error with version 2008.1.415.20 of Telerik.Web.UI.dll

MyPage.ASPX

<telerik:RadMenu ID="MyMenu" runat="server" OnItemCreated="MyMenu_ItemCreated" />

MyPage.ASPX.CS

	protected void Page_Load(object sender, EventArgs e)
	{
	if (!Page.IsPostBack)
	{
	MyMenu.LoadContentFile("~/XML/MyMenu.xml");
	}
	}
	protected void MyMenu_ItemCreated(object sender, RadMenuEventArgs e)
	{
	RadMenuItem item = e.Item;
	string roleName = item.Value;
	item.Enabled = Roles.IsUserInRole(roleName);
	// hide menu items based on role except for top level
	if (item.Level > 0)
	{
	item.Visible = Roles.IsUserInRole(roleName);
	}
	}

MyMenu.XML

<?xml version="1.0" encoding="utf-8" ?>
<Menu>
    <Group Flow="Horizontal">
        <Item Text="Page1" ToolTip="Page1" NavigateUrl="~/MyPage1.aspx" Value="MyRole1">
            <Group>
                <Item Text="Page 1a" NavigateUrl="~/MyPage1a.aspx" PostBack="true" Value="MyRole1a"/>
                <Item Text="Page 1b" NavigateUrl="~/MyPage1a.aspx" PostBack="true" Value="MyRole1b"/>
            </Group>
        </Item>
        <Item Text="Page2" ToolTip="Page2" NavigateUrl="~/MyPage2.aspx" Value="MyRole2">
            <Group>
                <Item Text="Page 2a" NavigateUrl="~/MyPage2a.aspx" PostBack="true" Value="MyRole2a"/>
                <Item Text="Page 2b" NavigateUrl="~/MyPage2a.aspx" PostBack="true" Value="MyRole2b"/>
            </Group>
        </Item>
    </Group>
</Menu>

item.Level > 0

That line throws the exception mentioned by the original poster.

I ended up creating a menu with css. Unfortunately I didn't have time to get back to Telerik.

I am [was] also getting this same error "Unable to cast object of type 'Telerik.Web.UI.RadMenu' to type 'Telerik.Web.UI.RadMenuItem'". With version 2008.1.415.

Line 3 of this code will throw the error;

	Protected Sub RadMenu1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMenuEventArgs) Handles RadMenu1.ItemCreated
	If e.Item.Level = 0 Then
	e.Item.Width = New Unit("100%")
	End If
	End Sub

Got around it by using;

Protected Sub RadMenu1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMenuEventArgs) Handles RadMenu1.ItemCreated

    If TypeOf e.Item.Parent Is Telerik.Web.UI.RadMenu Then
        e.Item.Width = New Unit("100%")
        'im at level 0, aka root...
    Else
        'im a sub menu item...
    End If

End Sub
