Hi,
Please find the dummy code. And, I believe the problem is if the column is having EMPTY values
Step:1
Once you get the grid then sort column "Name". You will get top 4 rows empty for "Name" column. I made them empty intentionally. You can change the code.
Step:2
Select the checkbox on row having ID 50
Step:3
Click "Display sort name" button
Result:
You will get a different ID instead of ID 50. But, if you sort ID then you always get correct ID.
