Hi all,

    Is there any way you can limit the export types in a Crystal Reports export dialog box ? Ive written a viewer in c#/.Net which works well, but I would like to limit the export options available to the user, say to PDF and XLS....

static drop down box with the two option, depending on selected value set your exportoption value accordingly.

Sorry, I should have said, Im using the standard Crystal Report component for .net which comes with its own toolbar, export option etc, so Im not actually building a drop down myself.....I was hoping to avoid creating one, just wanted to restrict the existing one.

can you post some code, im not too sure what you are using.

Im not sure what I can post as its a standard visual control you paste onto a form. I know I can specify the export type, and export like that, but I need to allow the user to select from a list. So, in the example below, Ive added code behind an 'EXPORT' button to export in Excel format, but Id like the user to choose from a controlled list...

// Declare variables and get the export options.
ExportOptions exportOpts = new ExportOptions();
ExcelFormatOptions excelFormatOpts = new ExcelFormatOptions ();
DiskFileDestinationOptions diskOpts = new DiskFileDestinationOptions();
exportOpts = ReportInstance.ExportOptions;

// Set the excel format options.
excelFormatOpts.ExcelUseConstantColumnWidth = true;
exportOpts.ExportFormatType = ExportFormatType.Excel;
exportOpts.FormatOptions = excelFormatOpts;

// Set the disk file options and export.
exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
diskOpts.DiskFileName = "C:\\temp.xls";
exportOpts.DestinationOptions = diskOpts;

ReportInstance.Export ();

Yeah I think you're going to have to create your own dropdown.  I dont see any other way around that.  its pretty simple though.

<asp:dropdownlist id="ddlExport" runat="server"
   <asp:listitem value=1>Excel</asp:listitem>
   <asp:listitem value=2>PDF</asp:listitem>

then set up another routine for the pdf export in your code behind and check the value of ddlExport to determine which routine to use.

Is this from a machine with Crystal installed or for the client machines.

From a VB application you can limit the export options by not including the export dlls in the installation.  The viewer looks for the dlls to populate the dropdown.  Don't know if that works with c# and .Net.
