When I try to open a file I'd like to be able to click on a link to an Excel file and have it open directly in Excel on my computer, without any intermediate popup windows. Is this possible? or download to local?
You can find an example that leverages RadFileExplorer for image preview and file download functionality to preview other file types like Excel in RadWindow. The open-pdf-word-excel-files-from-radfileexplorer.zip example is attached, and you can use it as a foundation for your custom document viewer implementation. Here are more details on the sample project:
OpenPdfFilesFromFileExplorer.aspx - This page includes the RadFileExplorer control and a custom JavaScript function that handles the double-click event on the files. Depending on the file extension, the RadPdfViewer or RadWindow will be used to preview the file.
PdfViewer.aspx - The PdfViewer.aspx page hosts the RadPdfViewer control.
PdfViewer.aspx.cs - The code-behind PdfViewer.aspx.cs handles the file loading and conversion based on the file type.
web.config - specifies the mime types of the file formats that are not supported by default by the browser
If you'd like to not convert the excel files (.xlsx file extensions) and proving them in the PdfViewer, but directly load them in RadSpreadsheet for ASP.NET AJAX then you can leverage the solution provided at Load Excel file into a read-only RadSpreadsheet. For your convenience I prepared and attached another example Open_Pdf_Word_Excel_Files_from_RadFileExplorer_in_RadSpreadsheet.
