I posted this originally on this thread Save to File but haven't gotten any replies for a few days, so maybe that thread isn't being looked at, so I'm reposting here.
I'm using RadControls for ASP.NET AJAX Q2 2012 SP2
I'm using the described method to export to excel file, and it seems to work if I'm exporting a single grid. However, In my case I have three grids and I need to export all three to seperate excel files, then continue to do some additional processing after the exports are completed.
When I attempt to export mutliple excel files one after the other, none of the exports work. NO errors, NO nothing, see code excerpts below.
In addition, is there any way to suppress the open/save dialog when writing the exported file to disk, other than
The issue seems to be with exporting multiple grids back to back.
I've also tried firing the Export Command from codebehind, the grids ItemCommand runs, but GridExporting doesn't.
Dim GCI As Telerik.Web.UI.GridCommandItem = CType(Me.rgSummary.MasterTableView.GetItems(Telerik.Web.UI.GridItemType.CommandItem)(0), Telerik.Web.UI.GridCommandItem)
Any help would be appreciated.
