We are using the RadGrid and it's custom paging abilities.
We have a grid where we only bind the "PageSize" (typically 10) to the grid and set the Virtual Item Count equal to the total number of items. (in this case, 897).
When we export to Excel, we have to set the "Page Size" property on the Grid (not the master table view) to the total number of items, rebind the grid to the full dataset and then allow the export. Otherwise, it will only export the current page.
We've noticed that after doing that, in the PageSize dropdown, there are items for the default (10, 20, 50) as well as the item number i exported which is 897.
How can i prevent that value from being saved into the PageSize dropdown.
