Hi Peter,
Glad to see your reply. On the second question, I tried the method you recommended, using the ‘refresh’ and ‘refreshview’ methods, which can be successfully solved at present. Thank you.
As for the first question, it is suggested to try the example on the official website. The specific address is as follows:
You can see that before sorting in the instance, we can select each row through the check box on the left. But when I sort the First Name column according to the letters A-Z, and then select a separate row, the order will be disordered. For example, when I click the check box in the first row, the second line is actually selected. Maybe you can have a try.
Thank you very much for your help.
