[Solved] RibbonView - Paint with MVVM example

[Trevor]

I would really appreciate your help to point me in the right direction.

I've been working through the example provided in order to build a dynamically generated menu but cant seem to find the code responsible for the following (where am I missing the ButtonsTemplateSelector in the code?):

<mvvm:ButtonsTemplateSelector x:Key="groupsSelector" Button="{StaticResource ButtonTemplate}"
                    SplitButton="{StaticResource SplitButtonTemplate}" ButtonsGroup="{StaticResource ButtonsGroup}"
                    SmallButtonGroup="{StaticResource SmallButtonGroup}" />

Hi Trevor,

I'm attaching the code for all RibbonView examples. In addition, here is the code for the ButtonsTemplateSelector.

using System.Windows;
using Telerik.Windows.Examples.RibbonView.MVVM.ViewModels;
using System.Windows.Controls;
using Telerik.Windows.Controls;

namespace Telerik.Windows.Examples.RibbonView.MVVM
{
    public class ButtonsTemplateSelector : DataTemplateSelector
    {
        public DataTemplate Button { get; set; }
        public DataTemplate SplitButton { get; set; }
        public DataTemplate ButtonsGroup { get; set; }
        public DataTemplate SmallButtonGroup { get; set; }

        public override DataTemplate SelectTemplate(object item, DependencyObject container)
        {
            if (item is SplitButtonViewModel)
            {
                return SplitButton;
            }
            else if (item is ButtonGroupViewModel)
            {
                return ((ButtonGroupViewModel)item).IsSmallGroup ? SmallButtonGroup : ButtonsGroup;
            }
            else
            {
                return Button;
            }
        }
    }
}

Let me know if you need further assistance.

Hi Kiril Stanoev,

Thank you very much, that's exactly what I was looking for.

I wonder if you can help me with one last problem I've encountered using the example of the RibbonView. I am trying to bind click events to the various buttons, but since the buttons are of type ButtonViewModel split = new ButtonViewModel(); and not of RadButton i cant access the Click event. What would be the best way to adjust the current example to allow this functionality?

Hi Trevor,

In my opinion, if you want to stay truly MVVM, you need to use commands for the buttons. Please take a look at the attached project in this forum post as it shows one basic implementation of a RadButton command (RadRibbonButton inherits RadButton, so commands are supported).
