Hi,

I am using a Tooltip control from Telerik which supports rich content (HTML) and I'd like to use it on the diagrams created with NetDiagram. 

Telerik has a demo of exactly what I'm looking to do, but it is based on an Image Map that is declared, not built dynamically.

Here's a snippet of what I'd need to do:

foreach (PolygonHotSpot spot in MapOfEurope.HotSpots)
            {
                //The first argument of add method requires the client Id
                //the example implementation will set the id to be the name of the country itself
                this.RadToolTipManager1.TargetControls.Add(spot.AlternateText, spot.AlternateText, true);
            }
 

Any idea how I would accomplish this with NetDiagram.  Is there some event (perhaps on the DiagramView) that I could leverage?

Thanks in advance for any advice.

Hi Stoyan,

Thanks for the prompt reply.
Your approach is causing the Telerik constructs to be created - I can see them when I do a View Source.
However, when I hover over a shape, I'm still getting the default tooltip.  Do I have to disable this, so that the Telerik one can fire?

Once again, any advice is much appreciated.

Hi,

I think there's something else going on here.
I am setting the "id" attribute as suggested, but I don't think that's what I need to use.  There's an "ID" attribute which is different - and what I think I should be using to register with Telerik.

Here's what I see under View Source.  I opted to go with a simple "area_#" approach:

<AREA SHAPE='POLY' COORDS='1419,174,1434,174,1434,189,1419,189,1419,174'
			TITLE="Click here to open this sub-process" ID="_mfusion_ctl00_ContentPlaceHolder_DiagramView1_ImageMap_0_0_21" href="javascript:document.getElementById('_mfusion_ctl00_ContentPlaceHolder_DiagramView1_ClickedItem').value = '21:-1:-1:-1';__doPostBack('ctl00$ContentPlaceHolder$DiagramView1','_mfusion_ctl00_ContentPlaceHolder_DiagramView1_ClickedItem');" id="area_1"> 

Is there any way that I can access the ID value (mfusion_ctl00...) in the OnCreatingAreaElement event handler?

Thanks

Jim
