WPF cannot access nested control

Question

Wondering if there's any trick to accessing a nested control in the code-behind ?

given some XAML along the lines of

<UserControl>    
    <textbox />
    <DataGrid Name="MyGrid">
        <Columns>
            <Column field=ABC>
                <EditType>
                    <ComboBox Name="myCombo1"/>

I can access this.MyGrid but cannot access this.myCombo1 !!

Everytime that I have run into this I have be able to resolve it by using x:Name instead of Name. This may not be the issue in your case but give it a try.

pretty strange, did not work for me ! I'm using vs2010 sp1, .net 4

@Kumar The example that you gave doesn't compile either I am missing some namespace or not knowing what control you are using for sure, can you give a more complete example that can be dropped into an UserControl and tested?

the sample uses devx wpf controls, i can upload more if you have those or are willing/able to install their trial versions

In simple cases you can access elements using their name, but looks like combobox is datatemplate part, you can work with visual tree at runtime using VisualTreeHelper, but if you use mvvm & code right usually you don't need to access elements directly. Can you provide more information on general problem or test project to reproduce issue?
