Bind data in winform datagridview without refresh

Question

Hi all,

I have one stock exchange API that returns data every second and I need to bind this data in c# winform datagridview.

But the problem is every time I bind data in the grid I need to write grid.Refresh(). if I don't write grid.Refresh() cell value not update.

Now I need a solution to bind data in datagridview without write grid.Refresh().

In short update cell value, every second so what I need to do.

I hope everyone can understand the above issue.

Thnx in advance.

2 problems to address as below DataGridView to refresh each time calling .Refresh() - This relates to the way you implemented. You need to use a strongly typed object to bind your grid. Then refresh will happen automatically each time. See "TimeDetail" class in the attached file. Same way to use. Scroll position to keep after each refresh - Use a class variable to keep DataGridView.CurrentRow.Index, then after bind, set that value with DataGridView.FirstDisplayedScrollingRowIndex. It will scroll up to the same position

But before all, what issue you are trying to fix here? I mean what is bothering on using Refresh(), as that is the preferred way than any custom implementation?
