Windows 10: System.NullReferenceException at...

Hello All,I have Windows 10 Version 21H1 OS Build 19043.1826 in my machine. I have a grid which pulls data from DB and shows it up on the screen. The grid has a top header for every column and all the headers contains filters. When the user selects on one of the header column then the grid gets filtered accordingly. The problem is when ever user tries to scroll horizontally the grid the application crashes with the blow call stack:I am facing similar problem as described in the below thread but could not find the details on the solution provided. Could you please help me to resolve this

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
