    Restriction of Export Formats
    In This Topic

    If only specific export formats should be available for the end user, the list of formats can be restricted exactly to these formats. This is possible with the option LlOptionString.Exports_Allowed.

    using (ListLabel LL = new ListLabel())
    {
        // Define/Assign data source
        LL.DataSource = CreateDataSet();
    
        // Only allow PDF and preview
        LL.Core.LlSetOptionString(LlOptionString.Exports_Allowed, "PDF;PRV");
    
        // Start export
        LL.Print();
    }
    
    Using LL As New ListLabel()
        ' Define/Assign data source
        LL.DataSource = CreateDataSet()
    
        ' Only allow PDF and preview
        LL.Core.LlSetOptionString(LlOptionString.Exports_Allowed, "PDF;PRV")
    
        ' Start export
        LL.Print()
    End Using
