First of all, thank you very much. It worked according to your reply. After successfully creating the filter, I tried to build on that and add some interesting features. But then a new problem arose, the problem occurred when I tried to use the ability to hide columns in grid with filters.
When I hide a column from display in this case, the corresponding filter below the column can not be hidden with the column. Therefore, the filtering of the whole grid is misaligned.
I don’t know if I’ve described it clearly enough.
I looked at the manual and felt that the filter and its properties were specific to the entire grid, but I didn’t seem to find any hidden/show properties that would control the corresponding filters below the individual columns.
How to solve this problem? Looking forward to your early reply. Thank you very much.
