Export data from RadTreeListView (Telerik ThirdParty)

Hi Everyone, I need to export the results contained in a RadTreeListView object. There is a lot of data inside and i can't afford to process cells and rows one by one (in terms of testing time) ...

    Try using the dotNET object obtained directly from the tree list object. Maybe the global dotNET object uses a different .NET version than that used in the app, and that causes conflicts.

    Also note that Export needs a Stream object, not a StreamWriter. A FileStream should work.

     

    var dotNET2 = RootApp.Grid.ContentControl.ContentPresenter.RadTreeListView.ClrAppDomain.dotNET;

    // Use dotNET2 to create parameters for the Export method call

// Initialize GridViewExportOptions
var options = dotNET2.Telerik_Windows_Controls.GridViewExportOptions.zctor();
options.Encoding = dotNET2.System_Text.Encoding.Unicode;
options.ShowColumnHeaders = true;
options.ShowColumnFooters = true;

// Initialize the FileStream
var fileStream = dotNET2.System_IO.File.Create(path);

RootApp.Grid.ContentControl.ContentPresenter.RadTreeListView.Export(fileStream, options);
fileStream.Close();

You can create a GridViewExportOptions object like this:

// JScript

// Get the dotNET object from the app,
// so that it's compatible with the app's .NET version
var dotNET2 = Sys.Process("YourApp").AppDomain("YourApp.exe").dotNET;

var options = dotNET2.Telerik_Windows_Controls.GridViewExportOptions.zctor();
options.Format = dotNET2.Telerik_Windows_Controls.ExportFormat.Xlsx;
options.Encoding = dotNET2.System_Text.Encoding.Unicode;
options.ShowColumnHeaders = true;

    Thousands thanks for you answer HKosova!
    I did not know about this trick, it will help me a lot in the future.

    Unfortunately i am getting exception while calling the Export method.
    Here is the exception:

    Invalid procedure call or argument
    Error location:
    Unit: "TestProject2\TestProject2\Script\Unit1"
    Line: 28 Column: 3. (Where i call the Export method)
     
     
    Here is my code:
      //Initialize GridViewExportOptions  
var dotNET2=Aliases.MachiningCloudApp.AppDomain("MachiningCloudApp.exe").dotNET;
  var options = dotNET2.Telerik_Windows_Controls.GridViewExportOptions.zctor();
  options.Format = dotNET2.Telerik_Windows_Controls.ExportFormat.Csv;
  options.Encoding = dotNET2.System_Text.Encoding.Unicode;
  options.ShowColumnHeaders = true;
  options.ShowColumnFooters= true;
  
  //Initialize the StreamWriter
  var sw =dotNET.System_IO.StreamWriter.zctor_5(path);
  sw.AutoFlush=true;

  //Call Export method (RootApp represents the parent aliases). RootApp.Grid.ContentControl.ContentPresenter.RadTreeListView.Export(sw,options);
  
  //Close the stream
  sw.Close();

     

    I am not really sure if i missed somthing or if the issue is on the app side.

    Thanks for you help!
