LOD Treeview+Images+Tooltip

[-DJ-]

Hi guys,

Scenario:
I have a LOD treeview which displays imagecategories as well as images from these categories.

I'm using the ImageUrl property of nodes to display thumbnails and I want to display the full size images when the user hovers each thumbnail.

Problems:
Consider this code taken from the treeview_nodexpand sub:

    While dtrReader.Read()

        Dim itemNode As New RadTreeNode(dtrReader("ImgName").ToString(), dtrReader("imgID"))
        itemNode.ImageUrl = ConfigurationManager.AppSettings(Session("DB") & "imgDir") & "small_" & dtrReader("imgName")
        itemNode.ToolTip = "<img src='" & ConfigurationManager.AppSettings(Session("DB") & "imgDir").Replace("~/", "../") & dtrReader("imgName") & "'/>"
        node.Nodes.Add(itemNode)

    End While

Despite having set the AutoTooltipify property to true in the tooltipmanager it doesn't kick in in this situation.

So instead of getting the full size image as a tooltip, I simply get the string <img src=' ...

Another minor problem is that the tooltip is just applied to the node.text and not the node.image.

Any thoughts?

P.S. As an end result I would really like to use LOD for the tooltips as well, I'm just not that far into this yet.

Hi -DJ-,

I prepared a sample project which demonstrates the desired functionality. Please, note that you should add an ID attribute to the RadTreeView nodes because they do not have an ID on the client.

Please, let me know if you need further assistance.

Hi Svetlina,

Thank you for the demo project.

I didn't manage to get it fully working though. I've given up on this approach and decided not to display any tooltips for the images.

Hello -DJ-,

If you change your mind and decide to use the RadToolTip for the RadTreeView, please provide more details about the experienced problem and best - open a new support ticket and send me a reproduction project which can be run without modifications along with detailed reproduction instructions. We will also upload a new online demo for RadTreeView and RadToolTip with our next release which is scheduled for the beginning of November and you can wait until it is available and use the demo.
