Hello,

in my application I need support for some type of library of predefined groups (a previously saved Selection of items maybe). Is there any support for this implemented, or do I have to save this all manually?

Best regards,

Alex

Hi,

just checked and it worked partially. I think the way over the DiagramView with CopyToClipBoard is a little bit more persistent, or am I wrong?

            if (diagram.Selection.Items.Count == 0)
            {
                MessageBox.Show("Select items to export");
                return;
            }
            SaveFileDialog sfd = new SaveFileDialog();
            DiagramView exportHelper = new DiagramView();
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                diagramView.CopyToClipboard(true, true);
                exportHelper.PasteFromClipboard(0,0);
                exportHelper.SaveToXml(sfd.FileName);
            }
 

And pasting it back in ...

            OpenFileDialog ofd = new OpenFileDialog();
            DiagramView exportHelper = new DiagramView();
            if (ofd.ShowDialog() == DialogResult.OK)
            {
                exportHelper.LoadFromXml(ofd.FileName);
                try
                {
                    foreach (DiagramItem item in exportHelper.Diagram.Items)
                    {
                        exportHelper.Diagram.Selection.AddItem(item);
                    }
                    exportHelper.CopyToClipboard(true, true);
                    diagramView.PasteFromClipboard(0,0);

                }
                catch (FileLoadException ex)
                {
                    MessageBox.Show(ex.Message);
                }
            }
 

Am I missing something? Maybe there are things not copied at all, but eventually you can help me with that, since AnchorPatterns and the links between grouped items are not stored.

Actually in version 5 the clipboard operations are implemented by calling public methods of the Diagram class that you could use in your situation. Use the

public SelectionCopy CopySelection(
     Diagram source, bool unconnectedLinks, bool copyGroups)

and

public bool PasteSelection(
     Diagram doc, SelectionCopy data, CompositeCmd cmd, float dx, float dy)

to copy the selected items and groups to a second Diagram, which you can save to a file.
