ArcGIS Pro二次开发打开对话框

ArcGIS Pro二次开发打开对话框

 

在ArcGIS Pro的二次开发中，很多时候需要加载或者保存特定格式的数据库，如选择FileGDB中的数据进行加载、选择.sde数据库中的文件进行加载、加载支持的栅格数据等等，很多时候需要需要利用Windows自带的打开或者保存对话框，进行数据的过滤和保存，这样做起来比较繁琐，最新的ArcGIS Pro开发包针对GIS的各种格式，封装了专门的打开和保存的对话框，如下

ArcGIS.Desktop.Catalog.OpenItemDialog

       ArcGIS.Desktop.Catalog.SaveItemDialog

在线的帮助地址为https://pro.arcgis.com/en/pro-app/sdk/api-reference/#topic8992.html

和https://pro.arcgis.com/en/pro-app/sdk/api-reference/#topic9001.html

这两个对话框使用的使用方式简单

如打开对话框

            OpenItemDialog searchGdbDialog = new OpenItemDialog

            {

                Title = "Find GDB",

                InitialLocation = @"C:\Data",

                MultiSelect = false,

                Filter = ItemFilters.geodatabases

            };

 

            var ok = searchGdbDialog.ShowDialog();

            if (ok != true) return;

            var selectedItems = searchGdbDialog.Items;

            foreach (var selectedItem in selectedItems)

                GdbPath = selectedItem.Path;

这个例子是打开GDB的数据，通过Filter属性进行选择过滤，运行结果如下：

保存对话框如下

              // Create the log file and write the current Folder-Connection's to it

              SaveItemDialog saveDialog = new SaveItemDialog();

              saveDialog.Title = "Export the current selected map series item";

              saveDialog.OverwritePrompt = true;

              saveDialog.DefaultExt = "pdf";

 

              // If the save dialog was not dismissed, create the file

              if (saveDialog.ShowDialog() == true)

              {

                await QueuedTask.Run(() =>

                {

                  Layout layout = layoutItem.GetLayout();

                  if (layout == null)

                    return;

                  // Create PDF format with appropriate settings

                  PDFFormat PDF = new PDFFormat()

                  {

                    Resolution = 300,

                    OutputFileName = saveDialog.FilePath

                  };

                  if (PDF.ValidateOutputFilePath())

                  {

                    layout.Export(PDF);

                  }

                });

这个是保存当前地图为PDF的例子，运行结果如下

 

可以通过过滤属性Filter进行需要数据格式的过滤操作，支持过滤的格式基本上涵盖了所有GIS支持的格式，支持的格式如下：

Name	Description
annotation	Supports browsing for annotation feature classes
cad	Supports browsing CAD datasets and the feature classes they contain
composite_addToMap	Supports browsing for items and datasets that can be added to a map. As a composite filter, the default filter allows you to browse for anything that is supported, but focused filters are also available to browse just for layers or geodatabase items, for example, that you want to add to a map.
composite_addToStereoMap	Supports browsing for items and datasets that can be added to a stereo map. As a composite filter, the default filter allows you to browse for anything that is supported, but focused filters are also available to browse just for layers or geodatabase items, for example, that you want to add to a stereo map.
composite_elevationSource	Supports browsing for web layers and datasets that can be used to define the elevation surface of a globe. As a composite filter, the default filter allows you to browse for anything that is supported, but focused filters are also available to browse just for images services, for example, that you want to define the ground.
composite_maps_import	Supports browsing for maps and layouts that can be imported to a project. As a composite filter, the default filter allows you to browse for anything that is supported, but focused filters are also available to browse just for ArcGIS Pro map or layout files, for example, that you want to import.
databases	Supports browsing all types of databases supported by ArcGIS Pro. Both database connections in a project and databases stored on a local or network computer can be browsed.
default_addToMap	Supports browsing all items or datasets that can be added to a map. This is the default filter in the composite_addToMap filter.
default_addToStereoMap	Supports browsing all items or datasets that can be added to a stereo map. This is the default filter in the composite_addToStereoMap filter.
default_import	Supports browsing all items that can be imported to a project. This is the default filter in the composite_maps_import filter.
dimensions	Supports browsing for dimension feature classes
featureClasses_all	Supports browsing all types of feature classes
featureDatasets_all	Supports browsing all types of feature datasets
folders	Supports browsing folder connections in the project and folders on a local or network computer
geodatabaseItems_all	Supports browsing all types of items stored in a geodatabase
geodatabases	Supports browsing all types of geodatabases supported by ArcGIS Pro. Both database connections in a project and databases stored on a local or network computer can be browsed.
kml	Supports browsing Keyhole Markup Language files
layers_allFileTypes	Supports browsing layer files and layer packages available from the active portal and from a local or network computer
locators_allTypes	Supports browsing all types of locators, including locator files and ArcGIS Server geocoding services
maps_all	Supports browsing maps in the project and all types of maps stored on a local or network computer
packages	Supports browsing all types of packages available from the active portal and stored on a local or network computer
project_templates	Supports browsing project templates available from the active portal and from a local or network computer
projects	Supports browsing projects and project packages available from the active portal and from a local or network computer
rasters	Supports browsing all types of rasters, including mosaic datasets and file-based raster datasets
services_addToMap	Supports browsing all types of web layers from the active portal and services from server connections in the project that can be added to maps
services_addToStereoMap	Supports browsing all types of web layers from the active portal and services from server connections in the project that can be added to stereo maps
services_all	Supports browsing all types of web layers from the active portal and services from server connections in the project that can be used in ArcGIS Pro
services_feature	Supports browsing feature services from the active portal and services from server connections in the project that can be added to maps
services_image	Supports browsing image services from the active portal and services from server connections in the project that can be added to maps
services_map	Supports browsing map services from the active portal and services from server connections in the project that can be added to maps
shapefiles	Supports browsing for shapefiles stored on a local or network computer
