is it possible to set the position of the picture inside a pictureBox?

like making a small pictureBox and putting a larger picture inside,,instead of showing only the upper-left most part of the picture,,it would be able to show different parts of the picture..

marked this thread solved. For others who need a durable answer: PictureBox.SizeMode only controls scaling/centering — it does not let you pick an arbitrary source offset inside the image. To show different parts of a larger image inside a smaller viewing window, use one of these reliable approaches.

One simple method is a Panel with AutoScroll: put a PictureBox whose Size equals the full image inside a Panel sized to the viewport, set Panel.AutoScroll = True, then adjust Panel.AutoScrollPosition (or the PictureBox.Location) to pan. Pros: minimal code and built-in scrollbars. Cons: the PictureBox must match the image size and scaling must be handled separately.

A more flexible approach is to draw the needed source rectangle in the PictureBox.Paint event. This allows precise control, panning, and optional scaling without creating extra images. Example pattern in VB.NET:

Private img As Image = Image.FromFile("…") ' load once
Private offsetX As Integer = 0
Private offsetY As Integer = 0

Private Sub PictureBox1_Paint(sender As Object, e As PaintEventArgs) Handles PictureBox1.Paint
    If img Is Nothing Then Return
    Dim src As New Rectangle(offsetX, offsetY, PictureBox1.Width, PictureBox1.Height)
    src.Intersect(New Rectangle(Point.Empty, img.Size))
    If src.Width <= 0 Or src.Height <= 0 Then Return
    Dim dest As New Rectangle(0, 0, src.Width, src.Height)
    e.Graphics.DrawImage(img, dest, src, GraphicsUnit.Pixel)
End Sub

Change offsetX/offsetY and call PictureBox1.Invalidate() to update the view. Notes: clamp offsets to image bounds, dispose any cloned/cropped images if using Image.Clone, and be mindful of scaling (if you want zooming, compute source rect in image pixels). If flicker appears, enable double buffering on the parent or draw to an offscreen bitmap first.
