Hi,

Yes, that sample was really helpful. I was able to generate a tree with that. However, I want to add three levels in my tree and at root level I want to add a static text.

For example at root level I want to add Book, at first level I want to add different categories of books and at second level I want to add the book names for those categories. The root level text is not stored in my database so I do not know how to bind that to the categories. Can you please suggest how I can achieve that.

Thanks,

Megha

Hello Megha,

I can say that the XamDataTree can display the items from the Source only, so if you want to add a root element you have to add it to the DataSource, too and define a NodeLayout for it. 

Hi,

I would like to enable drag and drop feature in XamadataTree which is binded to a dataset.  I want to drag nodes from one tree to another but every time I drop the node it disappears. Can someone please suggest how I can achieve that.

Thanks

Hello Megha,

I have created a sample project for you with the functionality you want. You need to hold control down in order to copy the TreeNode, because it is not allowed to move Nodes from one tree to another. If you want you can remove the item eplicitly in code.

Hope this helps you.

Hi,

I tried you solution but I am getting an error " Cannot add external objects to this list". Can you please suggest how to solve that problem.

Thanks

Hello Megha,

I have modified the sample I sent you before, so now you can Drag & Drop items without holding the control key down.

Hope this helps you.

Hi,

Is there a way I can achieve same functionality without holding Ctrl key ?

Thanks

Hello Megha,

As I wrote in my previous post, you have to hold "Ctrl" key down while you are moving the XamDataTree items.

I am able to drag and drop within one tree but not from one tree to another. I get as error message " Cannot add external objects to list"

Thanks
