Drag n Drop between Rad Treeview and Rad ListBox

[Mahitha Madala]

hi,

I am trying to drag items of a Rad Listbox into a Rad TreeView.

I have found how to do a drag and drop between two Rad ListBoxes. In the same way i have tried for the above senario.

Please can anyone help me how to implement Drag and drop between Rad TreeView and Rad ListBox.

Thank you.

regards,
Mahitha Madala

Hi Mahitha Madala,

Thank you for the question. Currently our controls do not fully support automatic Drag & Drop between each other, however it is trivial to do so. You need to use the standard windows forms drag and drop mechanism combined with a method that can be accessed through a RadElement instance. All RadElements have an ElementTree property which has a GetElementAtPoint() method. RadTreeView has a TreeViewElement property and RadListBox has a ListBoxElement property. They are of type RadElement and therefore ElementTree.GetElementAt() method can be accessed. This method will help you determine what you have clicked when you start dragging and what you are dropping on. Write again if you have other questions.

Best wishes,
Victor

Is there a way you can post the solution to this in a project file for C# and zip it up?

Thank you

Hi Anthony Pieper,

We do not have a ready solution which you can download. However, my colleague Victor gave a good description of what should be done in order to implement the desired functionality.

Generally, you can find an example of drag and drop between two RadListBoxes in our Examples application, section Combo & ListBox >> ListBox >> ListBox DragAndDrop. This should give you the idea of how the drag and drop fuctionality can be implemented.

All the best,

Hi,

What is the RadElement required to drop a node onto a RadDock? I would like to be able to create a DocumentWindow from the information attached to a node.

Thanks

Phil

Hello Phil,

Thank you for the question.

You can check whether the element on which you drop a node belongs to RadDock, for example:

RadElement element = this.radDock1.ElementTree.GetElementAtPoint(point);
if (element.ElementTree.Control == this.radDock1)
{
    DocumentWindow doc = new DocumentWindow(nodeText);
    this.radDock1.AddDocument(doc, DockPosition.Left);
}

If you have additional questions, feel free to contact me.

Sincerely yours,

Hello Pearl,

Thank you for contacting Telerik Support.

Please, find attached a sample project, demonstrating drag and drop functionality from RadGridView to RadTreeView. A sample video (drag and drop over the browser to play) is enclosed, illustrating better the implemented functionality. Note that this is just a sample solution and it may not cover all possible cases. Feel free to modify it on a way, which suits your requirement best.

Our Drag and Drop help article is quite useful about RadGridView's RadDragDropService. As to the case, related to drag and drop functionality from RadTreeView to RadGridView, please refer to our Modify the DragDropService behavior help article.

I hope this information helps. Should you have further questions, I would be glad to help.
