VS 2008 Combo Box question

LukeBadgerow — Fri, 18 Feb 2011 11:49:42 GMT

I've been mucking with this for too long, so anyone who wants to slap me about the back of the head with this would be greatly appreciated.

I've got a method that is calling out and returning an object[] of my coded value domain descriptions and I would like to push that to a combo box that is part of a dockable window that is a component of an editor extension add-in that I'm building

        public object[] GetDomainValues(String codedvaluedomain)
        {
            
            IWorkspace ws = (IWorkspace)ArcMap.Editor.EditWorkspace;
            if(ws == null)
            {
                ws = OpenSDEWorkspace("server", "5151", "database", "version", "user", "pass");
            }
            IWorkspaceDomains domains = (IWorkspaceDomains)ws;
            object[] domainobject = null;


                IEnumDomain domainEnum = domains.Domains;
                IDomain domain = domainEnum.Next();
                String name = "";

                while (domain != null)
                {
                    name = domain.Name;
                    domain = domainEnum.Next();
                    if (name.Equals(codedvaluedomain))
                    { 
                        break;
                    }
                }
                ICodedValueDomain codeddomain = new CodedValueDomainClass();
                codeddomain = domains.get_DomainByName(name) as ICodedValueDomain;
                domainobject = new object[codeddomain.CodeCount];

                for (int a = 0; a < codeddomain.CodeCount; a++)
                {
                    object domainvalue = codeddomain.get_Value(a);
                    String domainvaluename = codeddomain.get_Name(a);
                    domainobject.SetValue(domainvaluename, a);
                }
            
            
            return domainobject;
        }

the problem I keep running into is trying to create the entire array as a new object[] on start up/ or at some points even compiling.

I'm attempting to access in this manner:

this.mydomaincombobox.DataSource = this.utils.GetDomainValues(stringcodeddomainname);

Hi Luke,

I tried playing around with your code in a simple button add-in. I got it to work by replacing this line:

IWorkspace ws = (IWorkspace)ArcMap.Editor.EditWorkspace;

with:

// Get a reference to the editor extension
UID uid = new UIDClass();
uid.Value = "esriEditor.Editor";
IEditor editor = ArcMap.Application.FindExtensionByCLSID(uid) as IEditor;

IWorkspace ws = editor.EditWorkspace;

Not sure if it makes a difference that you're working with a dockable window in an editor extension.

Later... Ok, I see that in editor extensions, the ArcMap object has an "Editor" static member. So now I'm not sure why your code doesn't work. I will try to build a test editor extension with a dockable window and see if I make any headway.

I put together a test Add-In with an editor extension and a dockable window.

I refered to the custom selection extension sample for help.

In my testing, your GetDomainValues() method works when passed a valid domain name in the active edit session's workspace (which was a file gdb in my case).

To set the datasource for the combobox, I called a static method in the dockable window class from the extension just before showing the dockable window.

// in MyEditorExtension.cs
MyDockWin.LoadDomainCombobox("DirTypes"); // domain name is known for testing


// in MyDockWin.cs
public partial class MyDockWin : UserControl
{
    private static ComboBox s_comboBoxDomNames = null;
   
    public MyDockWin(object hook)
    {
        InitializeComponent();
        this.Hook = hook;

        s_comboBoxDomNames = this.comboBoxDomNames;
    }

    internal static void LoadDomainCombobox(String codedvaluedomain)
    {
        if (s_comboBoxDomNames != null)
        {
            s_comboBoxDomNames.DataSource = GetDomainValues(codedvaluedomain);
        }
    }

    private static object[] GetDomainValues(String codedvaluedomain)
    //... rest of your function unchanged

    //... rest of boilerplate in class

I hope that is some help.
