    I have a basic control that will be used in different areas. It has a couple of toolbars on it. I need to be able to add buttons to the toolbars in the control later on and I can do this right now no problem through code. 

    What I would like to be able to do is add the buttons in the XAML file like so
    <Controls:SomeControl  Name="smartList" ToolbarTopVisibility="Collapsed">  
                    <Button Name="_addButton" Margin="0,5,0,0" Click="AddButtonClick" 
                            Content="{Binding Path=ApplicationStrings.Add, Source={StaticResource ResourceWrapper}}"/>  
                    <Button Name="_editButton" Margin="0,5,0,0" Click="EditButtonClick" 
                            Content="{Binding Path=ApplicationStrings.Edit, Source={StaticResource ResourceWrapper}}"/>  
                    <Button Name="_deleteButton" Margin="0,5,0,0" Click="DeleteButtonClick" 
                            Content="{Binding Path=ApplicationStrings.Delete, Source={StaticResource ResourceWrapper}}"/>  

    as shown below, by adding a property ( Toolbar1 ) to my Control and returning the Items in the RadToolBar I am able to have the above code working, events fire and everything in general works just as you would expect.
    public class SomeControl     
        public SomeControl()     
        public ItemCollection RightButtons     
            getreturn Toolbar1.Items; }     

    The problem I am having is I would like to be able to access the buttons for enabling and disabling using the names declared in the XAML file. but when I try to do this the controls are null. the Items in the toolbar they are declared under are not null.

    Is there a way to make sure the controls I declared are not null so that I can access the buttons or any other control from the name I have given it?

    Hi Ben,

    For this particular scenario you will have to loop through ToolBar's items and find the desired buttons. Something like this:

    private void ToggleIsEnabled_Click(object sender, RoutedEventArgs e)
        // initially, the _add button is null, therefore we need to find it.
        if (_add == null)
            var result = (from n in slControl1.ToolBar1.Items
                    where (n as Control).Name == "_add"
                    select n).FirstOrDefault();
            _add = result as Button;
        // do whatever you want with the _add button
        _add.IsEnabled = !_add.IsEnabled;

    I am attaching my sample project for further reference. Have a look at it and let me know if it helps. I'd be glad to further assist you.
