Why does the image I bind to TreeView have to go through an event to display correctly

I first defined an imagelist, and added the images.The imagelist property on the TreeView was also bound to the imagelist that I defined, but after the formload event was completed, the root node of the TreeView displayed the first in the imagelist Icon, the icons of its subordinate nodes are correct;
However, after an afterselect event, the icon of the root node returns to normal. What is going on, thank you for your guidance.

It may be a refresh problem, try refreshing manually

The image display of the ImageList bound to the TreeView is problematic. The specific solution is to add a sentence immediately after binding
Application.DoEvent ();

The specific function is to the system Post Message: "I want to draw a picture", the system will draw Image after this

I am a winform program, how to refresh manually, please advise.

Is Application.DoEvent (); written in the last line of the pageload event?

TreeView.Refresh ()

There is no pageload in the winform program, just write this sentence immediately after the binding statement, and it is OK; there is no obvious binding, just in InitCompoenents();
