I solved the problem of multiple tooltips in following way.

I added below method in ToolTipService.cs

__private static void CloseAllToolTips()
{
var toolTip = GetToolTip(RootVisual);
foreach (var kvp in elementsAndToolTips)
{
//if (!(ReferenceEquals(kvp.Value, toolTip)))
kvp.Value.Visibility=Visibility.Collapsed;
kvp.Value.IsOpen = false;
}
}__

I called this method in TooltipService.cs where ever I want like OnElementMouseLeave and OnElementMouseEnter and so on. This certainly solved my problem.

I solved the problem of seeing a tooltip on my UI even though I move out of RadGridView.

__I gave my placement target as bottom__ and in ToolTipService.cs in PerformPlacement method, I gave following to display my tooltip/open popup only if the popup comes in valid position else do nothing.

case PlacementMode.Bottom:
case PlacementMode.Right:
case PlacementMode.Left:
case PlacementMode.Top:
var plugin = new Rect(0.0, 0.0, Application.Current.Host.Content.ActualWidth, Application.Current.Host.Content.ActualHeight);
var translatedPoints = GetTranslatedPoints((FrameworkElement)placementTarget);
var toolTip = GetTranslatedPoints((FrameworkElement)parentPopup.Child);
Point popupLocation = PlacePopup(plugin, translatedPoints, toolTip, placementMode);
parentPopup.VerticalOffset = popupLocation.Y + verticalOffset;
parentPopup.HorizontalOffset = popupLocation.X + horizontalOffset;
__var elements = VisualTreeHelper.FindElementsInHostCoordinates(new Point(MousePosition.X, MousePosition.Y), null) as List<UIElement>;
if (elements != null)
{
if (elements.Contains(CurrentToolTip.PlacementTarget))
{
parentPopup.IsOpen = true;
}
else
{
string s = "here";
}
}__
break;

When I move from one tab to another, the code was throwing exception, in order to solve this I gave the following if condition in GetTranslatedPoints method in ToolTipService.cs
__if (frameworkElement != null && frameworkElement.ActualHeight > 0 && frameworkElement.ActualWidth > 0)__

previously if was just __if (frameworkElement != null)__

I was able to solve multiple tooltips problems. Now, I always see ONLY one tooltip.

But I have one more problem. After sometime, I see a tooltip on my UI even though I move out of RadGridView. I tried many ways but could not solve it. Any help is highly appreciated. It's kind of urgent.

Created Issue: Tooltips not displaying properly with tabs [7212]

djcohen66 — Wed, 28 Nov 2012 19:46:40 GMT

When using the advacned tootip on a tabed interface, tooltips on the first table will not display after tabbing to to the second tab and then tabbing back. Attached is a small silverlight project that demonstrates this behavior.

Run the app, hover over the image on the first tab to see a tooltip. Select the second tab, hover on the image to see its tooltip. Select the first tab again and no tooltip displays. Switch back to the second tab and the tooltip there still works, but the first one will not work again until you refresh the page.

Commented Issue: TabControl Issue [6556]

gopalakrishnach — Thu, 04 Oct 2012 22:19:25 GMT

Hello, first of all, awesome product.
 
I have a tabbed application. The problem is that tabs will unload children from the visual tree, and thus the tooltip will be unregistered. when the tab is reactivated, the tooltip must once again be registered, which is not done in tooltipservice. Heres a short fully working example to demonstrate the problem with tabs.
 
1) Create a new Silverlight 4 project. Add references to System.Windows.Controls & Silverlight.Controls.Tooltips.
 
Paste this in your MainPage.xaml:
<UserControl x:Class="Repoduce_Bug_D_02315.MainPage"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
 xmlns:Controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
 xmlns:CustomToolTips="clr-namespace:Silverlight.Controls.ToolTips;assembly=Silverlight.Controls.ToolTips"
 mc:Ignorable="d"
 d:DesignHeight="300" d:DesignWidth="400">
 
 <Grid x:Name="LayoutRoot" Background="White">
 <Controls:TabControl>
 <Controls:TabItem Header="Tab1">
 <TextBlock Text="My textblock which has a tooltip">
 <CustomToolTips:ToolTipService.ToolTip>
 <CustomToolTips:ToolTip DisplayTime="Forever"
 InitialDelay="00:00:00">
 <TextBlock Text="My ToolTip contents"/>
 </CustomToolTips:ToolTip>
 </CustomToolTips:ToolTipService.ToolTip>
 </TextBlock>
 </Controls:TabItem>
 <Controls:TabItem Header="Tab2">
 <TextBlock Text="My textblock in tab 2 which also has a tooltip">
 <CustomToolTips:ToolTipService.ToolTip>
 <CustomToolTips:ToolTip DisplayTime="Forever"
 InitialDelay="00:00:00">
 <TextBlock Text="My ToolTip contents in tab 2"/>
 </CustomToolTips:ToolTip>
 </CustomToolTips:ToolTipService.ToolTip>
 </TextBlock>
 </Controls:TabItem>
 </Controls:TabControl>
 </Grid>
</UserControl>
 
 
How to reproduce: hold the mouse over the first text that appears. Works as expected. Change to tab2. hold the mouse over the text that appears. Works as expected. Change back to tab1. Now, the tooltip doesnt show up anymore. Change to tab2 and same thing here - the tooltip doesnt show up. The tooltip will not come back until the control is reinstanciated.
 
I posted a fix for this in patches.

I had the same issue and I fixed using below code int ToolTipService.cs

private static void FrameworkElementReloaded(object sender, RoutedEventArgs e)
{
var owner = sender as FrameworkElement;
if (owner == null)
{
throw new ArgumentException("Expected a FrameworkElement", "sender");
}
// Remove the loaded event, this may be fired again when virtualizing etc
owner.Loaded -= FrameworkElementReloaded;
// re-register tooltip
RegisterToolTip(owner, owner.GetValue(ToolTipObjectProperty));
}

private static void UnregisterToolTip(UIElement owner)
{
if (owner.GetValue(ToolTipObjectProperty) == null)
{
return;
}

var frameworkElement = owner as FrameworkElement;
//if (owner is FrameworkElement)
if (frameworkElement != null)
{
//((FrameworkElement)owner).Unloaded -= FrameworkElementUnloaded;
frameworkElement.Unloaded -= FrameworkElementUnloaded;
frameworkElement.Loaded += FrameworkElementReloaded;
}
owner.MouseEnter -= OnElementMouseEnter;
owner.MouseLeave -= OnElementMouseLeave;

var toolTip = (ToolTip)owner.GetValue(ToolTipObjectProperty);
if (toolTip.IsOpen)
{
toolTip.IsOpen = false;
}
toolTip.SetOwner(null);
// owner.ClearValue(ToolTipObjectProperty);

if (elementsAndToolTips.ContainsKey(owner))
{
elementsAndToolTips.Remove(owner);
}
}

Commented Issue: Tooltip does not work after closing childwindows [6981]

ethan2012 — Tue, 05 Jun 2012 17:44:47 GMT

Hi, I put the tooltip inside a child window for an info image. It works fine the first time i open the child window, but when i close the child window and click on the link in the parent window to open the child window again, and hover over the image, nothing happens, and the break point does not get hit. Does it unregister itself somehow?
Comments: ** Comment from web user: ethan2012 **

To fix this I added a Loaded event on the Owner. So, when we first register the tooltip, we should subscribe to both the Loaded and UnLoaded events of thge owner. And then in the Loaded event we need to register the tooltip again.

Commented Issue: Tooltip Problem [6701]

jtcooke — Wed, 28 Mar 2012 14:42:39 GMT

Same problem here. Using a tree control where the data gets re-populated every 10 seconds. My tooltip style has <Setter Property="DisplayTime" Value="Forever" /> because I don't want the tooltips to close until the user mouses out. The problem is if the tree data is reloaded, the tooltips get confused. They don't close and then there are multiple instances of the tooltip on the screen.

Commented Issue: Tool tip visible when parent containter is collapsed [6174]

anilchinnu21 — Thu, 09 Feb 2012 13:54:41 GMT

If you add a tool tip on a button that on click will be collapsed, the tool tip will remain visible causing the next tool tips on other controls to remain visible even if the mouse pointer is not over the control that contains the tool tip.

This is happening only when use the tool tip on a control that can be hidden while tool tip is visible.

Created Issue: Bug: Placement is wrong when PlacementTarget is not specified [6649]

RabidCow — Sun, 04 Dec 2011 03:24:48 GMT

Nice library! One slight issue though: if you set the Placement property, but don't set the PlacementTarget, the tooltip appears in the upper left corner. This differs from how the built-in ToolTip works. Changing the following line in ToolTipService.PerformPlacement from

UIElement placementTarget = CurrentToolTip.PlacementTarget;

to

UIElement placementTarget = CurrentToolTip.PlacementTarget ?? CurrentToolTip.Owner;

resolves this issue.

I love the possibilities with this but I also have a tabbed application and I have the same issue.

Where do I go for patches? Sorry, i'm new to this and can't find it anywhere. Please help! This is a great product but I HAVE to have this fixed and I'd rather not repeat work if its already done. Thanks,

Hello, first of all, awesome product.

I have a tabbed application. Heres a short fully working example to demonstrate the problem with tabs (might just be a general problem with visibility=IsHidden on elements, but tabs demonstrate it in a simple way).

I'll just post it here for information, and I'll be back if I manage to fix it myself, but this bug is not a top priority for me so that could take a while...

Created Issue: Regression due to memory leak fix: some tooltips are not displayed [6360]

clement_911 — Sat, 06 Aug 2011 11:15:49 GMT

Hi Xavier.
Nice library !
After updating to the latest version I noticed that some of my tooltips were not getting displayed anymore. That is because the Unloaded event deregisters the tooltip. However, the code should take into consideration that UIElements can be unloaded and then reloaded, for example if they get hidden and show again. After commenting that the FrameworkElementUnloaded it worked again. I haven't tried a fix, but I guess that the code should also re-register the tooltilp when the Loaded event occurs.
