[Solved] Exception in pager when exporting to CSV

[none123456]

I have a grid with a PagerStyle of NextPrevNumericAndAdvanced. When I try grid.MasterTableView.ExportToCSV(), I receive the error below.

When I set grid.MasterTableView.PagerStyle.Visible = false, the export works fine.

I think the pager is trying to register a script control for the page index or page size text boxes, during a rebind for the export (since IgnorePaging=true and rebinding is necessary).

Perhaps the grid should rebind before PreRender when exporting, so that if any of the child controls are script controls, they are being loaded early enough in the lifecycle to register themselves.
