I have a GridView which is bound to a datasource, which occasionally has a few thousand rows. I’ve obviously paged the results to avoid having such a huge grid.
I need to get the total of a certain decimal column however – currently I do a seperate query which is quite taxing considering the size of the datasource. Is there a way I can go through all the rows in the datasource, and get the total? I used to do this by calculating OnRowDataBound but this is now not an option due to the paging.
Ah, no, not without loadin them all which again makes it slow.
Normally the UI should not shwo a count but “more than x rows”.
Example:
Finished.
This is how most such interfaces work, including all of active directory maangement.
