and name my image and when I want to find my Image by name, here is my code:

I first do :

MIDL

myControlIcons[p, q].Source = myBitmapImage;
                   myControlIcons[p, q].Name = "ControlIcon_" + p.ToString() + "_" + q.ToString();
                   myGrid.Children.Add(myControlIcons[p, q]);

and then here when I got problem

C#

object myFE = myGrid.FindName("ControlIcon_" + p.ToString() + "_" + q.ToString());
               if (myFE != null)
                   MessageBox.Show("it is framework element");
               if(myFE == null)
                   MessageBox.Show("it is not framework element");

I don't understand why are you naming your control when you are adding to the Grid.

Check if Grid.Children.Count > 0 you use FindName function.

I name my Control and add it to my Grid in a method
then use that name in other methods that don't have reference to that control

I found the answer myself
the answer is that all names should be registered so the solution:

Grid myGrid = new Grid();
Image myImage = new Image();
myImage.Name = "myImage";

//here 
NameScope.SetNameScope(myGrid, new NameScope());

myGrid.RegisterName(myImage.Name, myImage);
