Hey,

We have an Windows Explorer kind of implementation where we have folders and files. We are using RadTreeListView for our application.

I need your inputs in following case:

1. Let's a user search for a file.
2. File is found and location is tracked.
3. In that case, my folder structure should automatically opened [in explorer via RadTreeView] and pointing to folder just tracked.

I'm trying to search file in already data bound RadTreeview. I tried to explore Items property but somehow it returned only null.
Can you please help, how to find a particular item/node in TreeListView?

Thanks,
Tarun

Cance check/uncheck action?

Here is what I am trying to achieve with tristate TreeView:

1. User unchecks an item from tree
2. Before the item gets really unchecked from tree, I need to put a validation
3. If item passes this validation, it should be unchecked. Else the uncheck event needs to be canceled and item should remain checked.

I tried setting e.Handled in PreviewUnchecked which is not working. The item gets already unchecked.

Any ideas how this can be achieved?

Creating Popup Menu at runtime

Hi all

The following code allows the creation of a control RadMenu at runtime with an item

Dim As New RadMenu NewMenu
newMenu.Name = "MyPopUpMenu"

Dim As New RadMenuItem newMenuItem
With newMenuItem
. Name = "Name_A"
. Header = "Option A"
End With

newMenu.Items.Add (newMenuItem)
newMenu.ClickToOpen = True

It works without problems but how I can:
1 - Make it visible, the object is created in memory but not a method I have "Display" or "Show" or the like to show it.
2 - Place it in a specific location, such as the mouse pointer.
3-Make it a shortcut menu, type Popup .....

Thanks to all .....

How to control the switching positions by drag and drop

Hello,
I want to change the way TileViewItems change their positions in the I want to change the way TileViewItems change their positions in the TileView so that when I drag an item to the left of another one it will change his position to the left of the dropped item and to the right accordingly without any other changes to the other items (I believe the way to do that is to pin all the others).

How would you recommend me to do so?

Thank you anyway!
