How can i get the value of the "UUID" field?

ChristianJührendt

Hello,

in an enterprise geodatabase there is a table "GDB_ITEMS" containing a field named "UUID". How can i get the value of the "UUID" field in ArcGIS Pro?

To start a process in ArcGIS Pro i created a custom button in the context menu of geodatabase featureclasses like so:

<modules>
<insertModule id="MetadataAddIn" className="HandleExportDocuments" autoLoad="true" caption="MetadataAddIn">
<controls>
<button id="MetadataAddIn_CreateMetadataPDF" caption="CreateMetadataPDF" className="CreateMetadataPDF" loadOnClick="true" smallImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/GenericButtonBlue16.png" largeImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/GenericButtonBlue32.png">
<tooltip heading="Tooltip Heading">Tooltip text<disabledText /></tooltip>
</button>
</controls>
</insertModule>
<updateModule refID="esri_geodatabase_module">
<menus>
<updateMenu refID="fgdbItemFeatureClassTypeMenu">
<insertButton refID="MetadataAddIn_CreateMetadataPDF" placeWith="esri_projectItemEditMetadata" />
</updateMenu>
<updateMenu refID="egdbItemFeatureClassTypeMenu">
<insertButton refID="MetadataAddIn_CreateMetadataPDF" placeWith="esri_projectItemEditMetadata" />
</updateMenu>
<updateMenu refID="fgdbItemTableTypeMenu">
<insertButton refID="MetadataAddIn_CreateMetadataPDF" placeWith="esri_projectItemEditMetadata" />
</updateMenu>
<updateMenu refID="egdbItemTableTypeMenu">
<insertButton refID="MetadataAddIn_CreateMetadataPDF" placeWith="esri_projectItemEditMetadata" />
</updateMenu>
</menus>
</updateModule>
</modules>

For the button "CreateMetadataPDF" there is an OnClick event. In this method i need the "UUID" value of the current featureclass or table from the geodatabase in the table "GDB_ITEMS". Currently i have the following code:

internal class CreateMetadataPDF : Button
{
protected override void OnClick()
{
GDBItem item = ProApp.ContextMenuDataContext as GDBItem;
}
}

How can i get the UUID here?

Which is the correct class to use here because GDBItem is marked as ESRI internal only?

 

Thank you!

 

Regards

Hi @ChristianJ1979 ,

Here is the codesnippet  and some useful help link for you.

https://github.com/Esri/arcgis-pro-sdk/wiki/ProSnippets-Geodatabase

The codesnippet cover for egdb and fgdb.

 

ArcGIS.Desktop.Core.IProjectWindow currentProjectWindow = Project.GetCatalogPane(true);
           
            if (currentProjectWindow == null)
            {
                MessageBox.Show("Please select a geodatabase from catalog");
                return;
            }

            int selectionCount = currentProjectWindow.SelectionCount;
            
            if (selectionCount <= 0)
            {
                MessageBox.Show("Please select a geodatabase from catalog");
                return;
            }
           
            Item SelectedConnection = currentProjectWindow.SelectedItems.First();
            
            string _gdbPath = this.SelectedConnection.Path;

                //check gdb or sde connection
                //apart from that it is handled by user and the properties need to setup manually

                if (gdbPath.AbsoluteUri.EndsWith(".gdb", StringComparison.OrdinalIgnoreCase))
                {
                    geodatabase = new Geodatabase(new FileGeodatabaseConnectionPath(gdbPath));
                }

                else if (gdbPath.AbsoluteUri.EndsWith(".sde", StringComparison.OrdinalIgnoreCase))

                IReadOnlyList<FeatureClassDefinition> fcd = geodatabase.GetDefinitions<FeatureClassDefinition>();//Get all feature class definition <== here you can get the feature class definition
// for your case specific table 
                using (Table featureClassAsTable = geodatabase.OpenDataset<Table>("GDB_ITEMS")) {
        // But it is really a FeatureClass object.
        FeatureClass featureClassOpenedAsTable = featureClassAsTable as FeatureClass;
FeatureClassDefinition featureClassDef = featureClassOpenedAsTable.GetDefinition();// you can get your desire field from here
IReadOnlyList<Field> fieldList = featureClassDef.GetFields();
                        var UUIDField = fieldList.FirstOrDefault(x => x.Name.Equals("UUID")); //for uuidfield ***
      }
               

            }, ps.Progressor);
