Fellow programmers - DataGridView Flickering problem...

[funk101]

I have a DataGridView displaying rows of data and I'm getting a really bad flickering on every update of OnMarketData(). Essentially, everytime the rows update it flickers white for a second. Googling this prob brought up a solution like the following:

public class CustomDG : DataGridView
{
public CustomDG()
{
this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true);
this.UpdateStyles();
}
}

This, however, doesn't solve it. Any help would be greatly appreciated.

Hi funk101, unfortunately this is not supported. Hopefully a fellow programmer can help you out.

funk,

I had this same problem when I used a DataGrid to create my own DOM. I finally gave up trying to use the DataGrid and manually drew my own grid on a panel. Seemed to work much better.

Well, I've reworked this code lot's. I needed a collection that was fast, and sortable, and needed to bind to the datagridview. I tried the BindingList<>, and bound it to the datagridview, that seems to be the problem, it's too slow when the data starts coming down the pipe. I reverted back to Dictionary<> converting to a List<> for the sort functions and then foreach()'ing and MANUALLY populating the List, (unbound) I guess, and it's working fine.
Lesson learned -> I think BindingList and binding automatically to a datagridview in this particular situation can't cut the speed.

According to my R&D, Dictionary is the fastest collection for whipping data around when you need <key, val>. (Correct me if I'm wrong, please anyone). I've read a lot of specs. SortedList, List, SortedDictionary, BindingList, etc.

What I need to do next is, make this indicator show up on the main chart window. Currently it pops up a new window. So I guess I need to do something like "Form within a Form" but I can't seem to crack the code yet. Any help? I understand how to override Plot() but not grasping how to stuff a Form in Plot().
