Thank you. I have implemented the code and initialize it as below:
' This call is required by the designer.
Me.RadImageEditor1 = New MyImageEditor
and on my form Load I try to create a blank bitmap image
Private Sub formImageEditor_Load(sender As Object, e As EventArgs) Handles Me.Load
RadImageEditor1.OpenImage(New Bitmap(500, 500))
but then it keeps opening the file open dialog when ever I try to Draw something.
