I created a windows form and it only contains the flowchart control. The flowchart control has RectangleF height = 2500 and the vertical scrollbar is enabled.

Here is the situation I am facing:

when my windows application loads up, the focus is not in the flowchart control.
I scroll down to the bottom of the flowchart control and click inside the flowchart control. The focus is now switched to the flowchart control. However, the scroll position back to the top of the control.

My question is:
How do I set the scroll position back to the position where the mouse was clicked so the position is not back to the top?

I have tried everything I can think of, but still no luck.

Could you please help on this one?

Thanks.

I don't have any Enter Event handler.

This situation only occurs when I try to switch the focus from other control to Flowchart control.

Once the flowchart control is in focus, I can scroll down to the bottom of the flowchart and click the mouse anywhere within the flowchart and the flowchart will stay.
