ArcGIS Pro Export Layout to Desktop Button

[WilliamHart1]

Hello all - I am trying to create a plug in button in Pro that takes the current layout view and exports the layout to the desktop. When I go to press the button the code runs with no problem but I am not receiving any output. If anybody could help - I would really appreciate it. Thank you.

Code below. 

using ArcGIS.Core.CIM;
using ArcGIS.Core.Data;
using ArcGIS.Core.Geometry;
using ArcGIS.Desktop.Catalog;
using ArcGIS.Desktop.Core;
using ArcGIS.Desktop.Editing;
using ArcGIS.Desktop.Extensions;
using ArcGIS.Desktop.Framework;
using ArcGIS.Desktop.Framework.Contracts;
using ArcGIS.Desktop.Framework.Dialogs;
using ArcGIS.Desktop.Framework.Threading.Tasks;
using ArcGIS.Desktop.Layouts;
using ArcGIS.Desktop.Mapping;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using static ArcGIS.Desktop.Internal.Core.PortalTrafficDataService.PortalDescriptionResponse;

namespace Export_Button
{
internal class Button1 : Button
{
protected override async void OnClick()
{
LayoutProjectItem layoutItem = Project.Current.GetItems<LayoutProjectItem>().FirstOrDefault(item => item.Name.Equals("Layout"));
Layout layout = await QueuedTask.Run(() => layoutItem.GetLayout());
String filePath = "//map.pdf";

//Export a layout to PDF

//Create a PDF export format
PDFFormat pdf = new PDFFormat()
{
OutputFileName = filePath,
Resolution = 300,
DoCompressVectorGraphics = true,
DoEmbedFonts = true,
HasGeoRefInfo = true,
ImageCompression = ImageCompression.Adaptive,
ImageQuality = ImageQuality.Best,
LayersAndAttributes = LayersAndAttributes.LayersAndAttributes
};

//Check to see if the path is valid and export
if (pdf.ValidateOutputFilePath())
{
layout.Export(pdf); //Export the PDF
}
#endregion Layout_ExportPDF
}
}
}

Also when changing the filepath an error shows up when pressing the button that shows "ArcGIS.Core.CalledOnWrongThreadException: 'This method or property must be called on the thread this object was created on." on the layout.Export(pdf) line of code. Any help would be greatly appreciated. Thanks!

Hi,

You need call layout.Export(pdf) on the MCT. It means , it must be enclosed in QueuedTask.Run.

//Check to see if the path is valid and export
if (pdf.ValidateOutputFilePath())
{
  await QueuedTask.Run(() =>
  {
    layout.Export(pdf); //Export the PDF
  });
}

Thank you for the response. With that update, there is no map export and the only thing that happens is the script shown below in the output window of Visual Studio. This solution did relieve the "CalledOnWrongThread" error.

@GKmieliauskas  is correct, you have to call the export method from the MCT.  Your example code worked fine for after i made a few correction and added some error checking:

protected override async void OnClick()
{
  try
  {
    LayoutProjectItem layoutItem = Project.Current.GetItems<LayoutProjectItem>().FirstOrDefault(item => item.Name.Equals("Layout")) ?? throw new Exception("Layout not found");
    Layout layout = await QueuedTask.Run(() => layoutItem.GetLayout());
    String filePath = @"c:\temp\map.pdf";

    //Create a PDF export format
    PDFFormat pdf = new()
    {
      OutputFileName = filePath,
      Resolution = 300,
      DoCompressVectorGraphics = true,
      DoEmbedFonts = true,
      HasGeoRefInfo = true,
      ImageCompression = ImageCompression.Adaptive,
      ImageQuality = ImageQuality.Best,
      LayersAndAttributes = LayersAndAttributes.LayersAndAttributes
    };

    //Check to see if the path is valid and export
    if (!pdf.ValidateOutputFilePath())
      throw new Exception($@"Invalid path: {filePath}");
    await QueuedTask.Run(() => layout.Export(pdf)); //Export the PDF
  }
  catch (Exception ex)
  {
    MessageBox.Show("Error: " + ex.ToString());
  }
}

Running the sample code above results in a c:\temp\map.pdf file:

I fixed the ProSnippet so that the Export method is now called from within QueuedTask.Run.  

Thanks for pointing this out.

This worked. Thank you!
