Export Grid - add Datetime or other info at upper page

I know we can using header image when exporting to pdf.
But image is static

If I want to add some Info into upper page ex:

Export Date: xxx
Total Rows : xxx
Data About: xxx

//Data from Grid


Please help me how to do this…

Thanks

Unfortunately only the static image can be insterted to the header of your exported pdf.

So there is no other way to insert info about filter by xxx if my Grid data generated using a dropdown…

Thanks
