Please clear my WPF controls doubt

Question

I was trying to migrate one of my WinForms project to WPF.

Is there any method to get all controls on a WPF Window similar to MyWindowsForm.Controls() or MyWindowsFormGroupBox.Controls() to access all controls on a WPF Window?

How can I have access to all controls on a WPF Window or a WPF grid (not DataGrid) pragmatically?

How can I access all controls in a WPF Window or WPF Grid, the Windows Forms way like this?:

For Each ctrl as Control in MyWindowsFormGroupBox.Controls()
If TypeOf ctrl is TextBox Then CType(ctrl, TextBox).Text = ""
Next

First you must understand that in WPF there is both a Logical Tree structure and a Visual Tree structure. Rather than go into a long description here I will point you to two good articles on the subject that also have sample code that will help you: The Code Project: Understanding the Visual Tree and Logical Tree in WPF C# Online.NET: WPF Concepts—Logical and Visual Trees

Thank you so much. I was just getting started and still many WPF concepts are not clear to me. I think your advice would do for my problem. Thank you. Sachin Joseph
