Hamburger Menu - Prevent Expanding

[Martin Hamilton]

I'm trying out the Hamburger menu, but when I click the 'Hamburger Icon" it begins to expand very slowly.  It's not as 'zippy' as in the demo... probably due to the complex control that is within the first menu item.

Anyway, I don't really want it to expand (I have it set to Compact) anyway.

Is there to prevent it from expanding when the 'hamburger icon' is clicked?

Hi Martin,

Currently, this is possible by creating a custom view element and overriding the Expand/Collapse methods. Here is a sample implementation:

class MyPageView : RadPageView
{
    protected override RadPageViewElement CreateUI()
    {
        if (this.ViewMode == PageViewMode.NavigationView)
        {
            return new MyNavView();
        }
        return base.CreateUI();
    }
    public override string ThemeClassName
    {
        get { return typeof(RadPageView).FullName; }
    }
}
class MyNavView : RadPageViewNavigationViewElement
{
    protected override Type ThemeEffectiveType
    {
        get { return typeof(RadPageViewNavigationViewElement); }
    }
    public override void Collapse()
    {
        //base.Collapse();
    }
    public override void Expand()
    {
        //base.Expand();
    }
}

I hope this will be useful. Let me know if you have additional questions.

Hi Dimitar,

It would have been nice to have just been able to set e.cancel = true on the PageExpanding sub routine... but that's ok.

BUT

1) I plugged in the two classes but when I plugged in the MyPageView class - this property throws an error;

Public Overrides ReadOnly Property ThemeClassName() As String     
Get         
Return GetType(RadPageView).FullName     
End Get
End Property

Error BC30362 'Public Overrides ReadOnly Property ThemeClassName As String' cannot override 'Public Overridable Overloads Property ThemeClassName As String' because they differ by 'ReadOnly' or 'WriteOnly'. QBSQLv2 D:\Ridgefield\QBSQLv2\QBSQLv2\FormMain.vb 2404 Active

2) Aside from that - can you explain how I would tie the RadPageView control into these classes to effectively prevent and expand.

So I instantiate the class but I can't see how to assign the RadPageView to the class(s)… can you give me an example?

Hello Martin,

I have logged a feature request for this in our Feedback Portal. You can track its progress, subscribe to status changes and add your comment to it here. I have also updated your Telerik Points.

1. I have attached a VB project that shows this. 

2. You can replace the class in the Designer.cs file (see attached image).

Should you have any other questions do not hesitate to ask.

Hello, Atfat,  
 
Note that the hamburger menu is achieved by the NavigationView in RadPageView. RadPageView supports right-to-left functionality but for the NavigationView it is not properly implemented yet. It seems like a reasonable request and I have logged it in our feedback portal. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

I hope this information helps.
