Load on demand

Hello,

Im about to add a treeview to a winform that will load hierarchical information. This data could get large at the root level, so ive started looking at ways to avoid loading it all at once. Im familiar with the ASP.NET treeview, so I thought Id give the winform version a shot also.

With the data I will be dealing with there will be a "level" indicator such as 1,2,3, 4 etc, that determines where in the hierarchy the item should be. With the ASP.NET trees Ive used, I typically filter the data to the first level, then add those nodes. Then do the same sort of thing when a node is clicked.

My question is - how do I attach data to the node, as well as simply give it a name. With the ASP.NET version, there would be a "value" attribute as well, which let me use that value to feed into other code that would go pull the next set of records.

Maybe im just not reading the right set of examples ?

help ?

Moving RadListBoxItems from one Listbox to the other

2008Q2

If I move ListBoxItem objects from one Listbox to the other, for example with
code like that:

listbox1.Items.AddRange(listBox2.SelectedItems.ToArray())

and then remove those items from list box 2:

foreach(RadListBoxItem item in litstbox1.Items)
{
    if(listbox2.Items.Contains(item))
    {
        listbox2.Items.Remove(item)
    }
}

strange things happen. I can no longer select the moved nodes in listbox1 (even though the texts appear).

I guess a RadListBoxItem cannot be in two listboxes at the same time (but then, an Exception should be thrown).

I tried to avoid this by using an intermediate List<RadListBoxItem>, but this did not work either.

Finally ended up with creating code like this:

foreach(RadListBoxItem in listbox2.SelectedItems)
{
    listbox1.Add(new RadListBoxItem(item.Text,item.Value))
}

which works but IMHO is not very elegant.

BTW: The forum does not work well with latest versions of Firefox.

ShapedForm in VS2008 Designer

I have a problem with ShapedForm (RoundRectForm) in VS2008 designer. Every time I open it in design mode, the size of the form changes (usually height grows). It happens even if there is nothing on the form. However, if there is no shape for the form defined, everything is OK (I didn't check other shapes).

The size is also different from designed, while app is running. Is there any way to avoid this behaviour?

best regards

Preventing DockPanels from being droped into DocumentPanes

Is it possible to prevent dropping DockPanels into DocumentPanes?

I have added a DockingManeger into my application. After file opening I am dynamically creating toolboxes (DockPanels) docked to the left of my form and a document (DocumentPane) filling the DockingManager. I want to prevent user from droping toolboxes into opened document and yet I want user to be able to dock toolboxes to any side of the form.

Activate MDI Child

In an MDI app, when I click on the tab for an existing document, the Active MDIChild of the DockingManager doesn't get set.
I have the IsMDIContainer of the form set to true
I have the AutoDetectMdiChildForms set to true.

What else am I missing?

Thanks,
Eric
