What I have tried:

I have tried this code but its working on button control..

Public Class test
Dim a As Boolean = False

Private Sub Button1_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseUp
a = False
End Sub

Private Sub Button1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseDown
a = True
End Sub

Private Sub Button1_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseMove

If a = True Then

Button1.Left = Control.MousePosition.X - Me.Left - 10
Button1.Top = Control.MousePosition.Y - Me.Top - 40

End If

Please clarify: are you wanting to move PictureBoxes inside a UserControl ?

Also, please update your code to show your use of PictureBox elements and UserControl.

Firstly, that's VB, not C# - it's important to tag your question correctly!
Second, if it works for a Button then it should work for a UserControl.
The best way to do it is to replace the fixed dependency on Button1 with a generic Control, and use the sender parameter to identify the control that is involved:

VB.NET

Private Sub Control_MouseMove(sender As System.Object, e As System.Windows.Forms.MouseEventArgs)
	Dim c As Control = TryCast(sender, Control)
	If a = True Then
		c.Left = Control.MousePosition.X - Me.Left - 10
		c.Top = Control.MousePosition.Y - Me.Top - 40
	End If
End Sub

And use that to handle your events.
