I'm working on winfom application c#. I have two forms called Welome and Details. Details contains 7 grids in the Panel.

Scenario: If I click on any of the item on welcome page it will take to the Details page with seven grids. If I drag the scroll bar down, and come back after moving back to welcome form, still the scroll bar stays at the same position.

Question: I want to reset the scroll position to top each time the user visits the details form, so that I can always see first grid.

If Angshuman Agarwal's answer doesn't work for you, the culprit is likely that after load some control in the form is receiving focus, which will scroll into view and override any changes to the scroll position.

You could set TabStop to false, but then your form wouldn't be tabbable :(

A clunky work-around, but still relatively simple fix, is manually fire focus on the first control in your form:

yourFirstControl1.Select();
