Hi Ian,
You can see the auto scrolling on drag and drop feature in the Drag and Drop example of RadTreeView in the Quick Start Framework. In that example, drag a node slowly to the bottom/top of the RadTreeView control.
You have understood the idea correctly, but the current implementation may not work as you expect it in all cases. For example if you drag the node outside the area of the RadTreeView too quickly it will not scroll automatically.

Hello,
I've got exactly the same problem... I tested to drag the node slowly as you described, but without success.
The AutoScroll functionality doesn't work for both directions - only for scrolling to top. If I try to drag a node to bottom, nothing happens.
Best regards.

Hello Nadine,
Thank you for your question.
Please do the drag without going out of the TreeView bounds. Just drag a node toward the bottom or the top and see if it works. Also note that you have to move your mouse around a bit in order for the scroll to work continuously.
I am currently testing it here and it seems to work reasonably well. Could you also tell me what version of our controls you are using? If your version is outdated, chances are that this is the reason.
I am looking forward to your reply.
All the best,

Hi,
I'm using Q3 2003 SP2.
I tried it again - without success...
Could the horizontal scrollbar be the problem?
Best regards.

Hi Nadine,
You are right. The horizontal scrollbar is causing trouble. This seems to be a bug and will be fixed in one of our future releases. I am sorry if this causes you trouble but we had not encountered this problem before. If you re-size the tree view to be wide enough so that the horizontal scroll disappears, the auto scroll should work as expected.
I would advise you to upgrade to the newest version of our controls (Q3 2008 SP2). We have done numerous improvements, fixes and tweaks and our controls use less memory.
Please write again if you have other questions.

Hi,
thank you for your reply.
I have the newest version - this was a typing error.
Desperately, it is not an option for me to resize the tree to loose the scroll bar. There's not enough space in my form.
What do you think, when will you release the next version that includes the fix?
Best regards.

Hello,
thank you. I'll wait for the fix.
Normally, I should get an update of my points, right?

Hi Victor,
I'm looking into a reported bug in an App I wrote which is essentially, the drag and drop autoscroll needs to move the mouse continuously in order for it to scroll the listbox target. Is this normal behaviour? Is there any way to make it scroll continuously purely on the position without having to move the mouse about while dragging?
The problem I'm having is on the Telerik Silverlight drag and drop functionality so sorry about the slightly off topic. I've not been able to find anything on Silverlight autoscroll.
thanks,
Stephen

Hi Stephen,
I am sorry for the delayed reply,
Unfortunately currently the automatic scrolling is triggered on mouse move and it is not possible to override this behavior.
You bring up a valid point though and I have added this improvement in the product backlog for the DragDrop.
Unfortunately I cannot suggest a date by which the improvement will have been implemented.
Your Telerik Points have been updated for your feedback.
Kind regards,

Without fixing the height for the Radtreeview,how to provide autoscroll option on dragdrop for radtreeview.

Hello swathi kajjam,
The auto-scroll feature is now implemented as discussed here. Are you experiencing problems with it? In what scenarios?
I created a very simple solution where auto-scroll works without setting the Height of the TreeView. Am I missing something?

Hi Miroslav,
Thanks for your reply,
This is my Code,where iam giving the height to the Radtreeview as autoscrollup on drag drop is not working. The Problem which iam facing is that, once if the user tries to drag and drop from one node to another node and if the dropping node is outside the screen view,user is unable to drop to the node where he actually wants to drop.
I have checked with all the properties of RadTreeview for AutoScrolling option on Drag Drop,but it dint worked for me.So,Can you please let me know,to provide such option what properties do i need to set.

Hello swathi kajjam,
This is a thread regarding RadTreeView for Silverlight and I suggest we do not mix it with the ASP.NET Ajax counterpart. Please open a new support ticket or forum thread in the respective area.
Thank you for your understanding.
