MapTips HideDelay multiple feature layers

DaveOrlando — Mon, 21 Feb 2011 18:43:44 GMT

Hello,

I am experiencing some odd behavior after adding a second FeatureLayer (with MapTips) to my map.

It seems that the MapTipHideDelay is only honored by one FeatureLayer at a time?.... If both features are visible and using MapTips, (line and polygon, but not overlapping) it seems like the last loaded MapTip will honor the HideDelay but the other goes back to no hidedelay.

tough to replicate, sometomes they both seem to work, other times not. Is anyone experiencing similar results and also, has there been more work done on maptips since 2.1.0.427

Any help would be great, thanks.

I think I know what you are talking about. If you use the following sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#GraphicsMapTip

Only the States layer have a MapTipHideDelay. When you mouse over Washington and then to another feature (States layer: Idaho or Cities layer: Spokane), the MapTipHideDelay is not used. This is by design, once you enter another feature, the previous map tip should close immediately to open another map tip. If however, you are moving your mouse from Washington towards Vancover where there is no other feature, you will find that the MapTipHideDelay is used.

Could you verify that this is the behavior you are seeing in your app? If not, please send share code that will help us reproduce the issue. Thanks.

Hi Jennifer,

Unfortunately this was not the case. None of my features overlap at all, yet the MapTips do no play well together. They never all (3 feature layers) honor the HideDelay. Usually either my polygon layer works and the two line features don't or vise versa, but never all three.

It think it has something to do with how they are initialized. My poygon layer is by selection, so it is tied to an editor, the line features are on demand, with scale dependency so each of the three layers are, by design, turning on and off quite frequently and hence, the delays are maybe not getting set? does that make sense?

Can you share some code that will help us reproduce with one of the sampleserver feature services? Thanks.

Dear all,

We seem to be seeing the same weird behaviour. We are dealing with GeoRss layers using ESRI.ArcGIS.Client.Toolkit.DataSources.

We can add MapTips and if there is only one layer on the map the HideDelay property works great. But when we add more then one Graphic Layer i.e more then one GeoRss layer then all turns to custard. The HideDelay property does not get honored.

This is the code: GraphicsLayer.SetMapTipHideDelay(maptip, new TimeSpan(0, 0, 1));

maptip is a user control. Just a stack panel. Nothing more.

Any advice on how we could fix this?

Any help would be appreciated.

Do all FeatureLayers share the same FrameworkElement maptip?

I was not able to reproduce this if each layer had a different maptip. It might be simpler to set this in XAML:
esri:GraphicsLayer.MapTipHideDelay="00:00:01.5"

Dear Jennirer,

What do you mean by different map tip? Can you provide a code example?

I our case we have a user control for the map tip. We instantiate an object and then assign it to the map til. The HideDelay is set once when we load each layer. So if we have 3 layers this is set 3 times.

GraphicsLayer.SetMapTipHideDelay(maptip, new TimeSpan(0, 0, 1));

We also tried to set it in XAML as you suggested but it doesnt seem to help.

After i add the second layer the map tips start missbehaving.

This is the code we have for the UserControl used for the MapTip

How do you initialize the maptip of your layers?

Jennifer's question is important : 'Do all layers share the same maptip?'

Be sure you create a new maptip by layer.

This is the piece of code:

void g_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
        {
            Graphic g = sender as Graphic;
            GeoRSSItem maptip = new GeoRSSItem();
            Binding bindingTitle = new Binding("[" + "Title" + "]");
            maptip.labelTitle.SetBinding(TextBlock.TextProperty, bindingTitle);

            //maptip.hyperlinkButtonTitle.SetBinding(HyperlinkButton.ContentProperty, bindingTitle);

            Binding bindingLink = new Binding("[" + "Link" + "]");
            maptip.hyperlinkButtonTitle.SetBinding(HyperlinkButton.NavigateUriProperty, bindingLink);

            Binding bindingSummary = new Binding("[" + "Summary" + "]");
            DescriptionConverter descriptionConverter = new DescriptionConverter();
            bindingSummary.Converter = descriptionConverter; //assigning the description converter

            maptip.labelHiddenLogic.SetBinding(Label.ContentProperty, bindingSummary);

            g.MapTip = maptip;

            //GraphicsLayer.SetMapTipHideDelay(maptip, new TimeSpan(0,0,1)); -- this has been moved to XAML
        }

Hi all,

We have also tried playing with MouseEnter and Mouse Leave events and resetting the MapTip Hide delay. Also tried setting this in XAML.

None seem to fix the issue.

Any advice on workaround or fix?

I would be happy even if possible to on mouse enter to show the map tip and dont hide it unless the user manualy closes it. To do that on MouseEnter i set map tip to Visible and do not hide it.

However even with doing that the MapTip on mouse leave just dissapears.

hmmm. Almost exausted all options 😞

Any advice appreciated.

Hi Jennifer and DanDan,

Thanks for bringing this thread back to life.

I have still not solved this issue, only ignored it for a few months.

Here is all my xaml and xaml.cs, thought this would be easier than trying to pick out the issues.

Like I mentioned from the top, I have three FeatureLayers: one polygon layer that is 'SelectionOnly' and two line features that are 'OnDemand' with a min resolution set. MapTipHideDelays sometime work, sometimes don't....

Any help will be appreciated, Dave

Re: MapTips HideDelay multiple feature layers

JenniferNery — Fri, 27 May 2011 16:25:48 GMT

I checked that your XAML-code sets the same MapTipHideDelay for the 3 FeatureLayers.

esri:GraphicsLayer.MapTipHideDelay="00:00:01"

You also mentioned that some of the features from different layer overlap, at which time the MapTipHideDelay is not respected - was this the problem? If yes, this is by design. When you enter a new graphic that has map tip, the currently opened map tip will close even if its hide delay time has not yet elapsed.

DaveOrlando — Fri, 27 May 2011 16:41:06 GMT

Hi,

Overlapping features is not the culprit, in some places yes they do overlap, but the problem exists in non-overlap situations too. Completely seperate features, Maptips flash and don't allow anymovement inside.

Am I getting too complex by putting buttons inside the MapTip? All three maptips are a different configuration.

Re: MapTips HideDelay multiple feature layers

JenniferNery — Sat, 11 Dec 2021 09:39:49 GMT

Maptip is handled in the GraphicsLayer. FeatureLayer inherits from GraphicsLayer. This should be similar to your sample only a lot simpler. Also, what's contained in the maptip should not affect when the maptip is opened or closed so for simplicity, I am using a TextBlock.

Please try this or minimize the code sample you sent. If you can provide us the steps to reproduce: like mouse over feature from one layer to the other or have some of the features overlap, etc.

2.2 seems to have cleared this up, (please note that the original post refers to build 2.1.0.427)
