New Post: ToolTip Placement

prashantphalle — Tue, 23 Apr 2013 10:31:25 GMT

Hi there,

I also experienced similar behaviour as described in previous thread "ToolTip Placement not working as expected"
But I found that the workaround for it is that, if you place the content of tooltip in separate tags enclosed by the control tags, instead of setting the ToolTipService.ToolTip property of the control works for me.
But I dont want to use this workaround and want to set the ToolTipService.ToolTip property.
Currently in such case my tooltip gets in to the top left corner i.e. 0,0 th location. Is anybody having solution for it?

New Post: Tooltips stay opened

madben2000 — Mon, 09 Jul 2012 07:19:04 GMT

When opening a ChildWindow, it sometimes happens that when you hover with the mouse over the screen, the tooltips stay opened and will not close until you navigate away. How can I close all opened tooltips when opening a childwindow?

New Post: Tooltip reopened on unloaded controls

moondog — Fri, 23 Mar 2012 02:14:55 GMT

I had a problem using this as a validation error tooltip in grids where if the user hit esc to cancel the edit while the tooltip was still open, i think the control (textbox) which the tooltip was attached to went away, but the tooltip stayed open. initialy i got an exception in GetTranslatedPoints() on this line:

try
{
generalTransform = frameworkElement.TransformToVisual(null);
}
catch (Exception ex)
{
//Debugger.Break();
return pointArray;
}

which i handled as you can see. but the toooltip move to the top left corner and stayed open. this is becuase in the returing method, PerformPlacement, the pointArray had data in it. so in PerformPlacement() i determined if pointArray had no data, I then set the reference to the Tooltip, CurrentToolTip, to null. Then the tooltip woud disapear and continue to re-appear. I found that if I stopped the time. all began to work correctly. bellow is the code I added after returning to PerformPlacement:

// Before getting the exception...
var translatedPoints = GetTranslatedPoints((FrameworkElement)placementTarget);

// Returning back to PerformPlacement.  Test to see if no points have been set.  if not, then we handled the expetion and need to kill the tooltip.
if (translatedPoints.Length == 4 && translatedPoints[0] == new Point() && translatedPoints[1] == new Point() && translatedPoints[2] == new Point() && translatedPoints[3] == new Point())
{
    CurrentToolTip.Timer.StopAndReset();
    CurrentToolTip = null;
    return;
}

all is good now.

New Post: Tooltip lost after drag and drop

mirceas — Tue, 20 Mar 2012 15:00:40 GMT

Hi,

I have a simple user control with a tooltip attached. If I drag&drop the control arround (it's the type of functionality I need), the tooltip gets lost, does not show anymore.
In my drag&drop scenario I need to move the control in the visual tree, I don't just reposition it relative to the parent container.
It sounds something like: as soon as I moved the control in the visual tree, the ToolTipService looses the MouseEnter and MouseLeave events of the owner element.

Any ideas?

Thanks,
Mircea

New Post: Missing sample application source code?

c4rnage — Fri, 24 Feb 2012 13:11:24 GMT

Hi, when I click the link to download the sample application source code, I just get the release dll, no source code. (I can run the sample application from it's link)

Am I missing the actual source code link somewhere?

Thanks

New Post: Tooltips do not close!

qi_george — Wed, 25 Jan 2012 14:22:59 GMT

We have tried to use this tooltip service to extend the show duration to 30 seconds with a dynamical, databinding DataGrid to show some cell information. We have met the issue of not-closing tooltips -- same tooltip popup can occur many times and unable to close...

We are forced to roll back to the default tooltip service, which only shows tooltips for 5 seconds.

We do not need any animation to bring up a tooltip, only extend its life so that the user have time to read the info in it.

Could someone give me a hint as to how to fix tooltips do not close issue?

When using the tooltips in a childwindow, in which I have a datagrid, the above error occurs when showing a tooltip and scrolling in the datagrid (OnDataContextChanged in ToolTipService class).

Does anybody have a solution for this?

Using the downloaded DLL version 2.20 in a clean test project all works fine. However, when trying to use the same code and DLL in a more complicated project with multiple views I get the error:

"The attachable property 'ToolTip' was not found in type 'ToolTipService'. The tooltip code that I placed in my XAML file is very simple as shown below. Anybody have any ideas where I can start looking for why this error is thrown at run-time.

New Post: Exception when resizing root window

safor — Sun, 20 Nov 2011 12:16:20 GMT

I encountered the same issue in a navigation application. Please see the description at http://tooltipservice.codeplex.com/discussions/280147

New Post: Exception when resizing root window in navigation application

safor — Sun, 20 Nov 2011 12:14:51 GMT

I encountered an issue described at "Exception when resizing root window" (http://tooltipservice.codeplex.com/discussions/246428) in a naviration application.

I have a standard Silverlight navigation application. Page1 uses the Advanced ToolTip to display some information for an UI element on the page. After ToolTip was displayed (it is important), I can resize the browser window without any issue. Then I navigate to a Page2 that does not have any Advanced ToolTip controls. Resize of the browser window causes the following exception:

System.ArgumentException was unhandled by user code
Message=Value does not fall within the expected range.
StackTrace:
       v MS.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData)
       v MS.Internal.XcpImports.MethodPack(IntPtr objectPtr, String methodName, Object[] rawData)
       v MS.Internal.XcpImports.UIElement_TransformToVisual(UIElement element, UIElement visual)
       v System.Windows.UIElement.TransformToVisual(UIElement visual)
       v Silverlight.Controls.ToolTips.ToolTipService.GetTranslatedPoints(FrameworkElement frameworkElement)
       v Silverlight.Controls.ToolTips.ToolTipService.PerformPlacement(Double horizontalOffset, Double verticalOffset)
       v Silverlight.Controls.ToolTips.ToolTipService.OnRootVisualSizeChanged(Object sender, SizeChangedEventArgs e)
       v System.Windows.SizeChangedEventHandler.Invoke(Object sender, SizeChangedEventArgs e)
       v System.Windows.FrameworkElement.OnSizeChanged(Object sender, SizeChangedEventArgs e)
       v MS.Internal.JoltHelper.RaiseEvent(IntPtr target, UInt32 eventId, IntPtr coreEventArgs, UInt32 eventArgsTypeIndex)
InnerException:

Under the debugger I can see where it exactly fails (code based on the change set #63304):

// in ToolTipService::GetTranslatedPoints method, line 437
var generalTransform = frameworkElement.TransformToVisual(null);

// in ToolTipService::PerformPlacement method, line 416
var translatedPoints = GetTranslatedPoints((FrameworkElement)placementTarget);

// in ToolTipService::OnRootVisualSizeChanged method, line 289
PerformPlacement(CurrentToolTip.HorizontalOffset, CurrentToolTip.VerticalOffset);

Please consider a workaround for this issue: to check whether a popup is open at the beginning of the PerformPlacement method. The code looks like this:

private static void PerformPlacement(double horizontalOffset, double verticalOffset)
{
     if (!CurrentToolTip.IsOpen)
     {
          return;
     }

     ...     
}

I consider my workaround more like a hack. It would be nice to see a better solution.

New Post: ToolTip Placement not working as expected

xavierdecoster — Tue, 11 Oct 2011 20:08:52 GMT

Hi all,

apologies for the delay here, but I'm running a bit out of time in order to maintain this project (this is a spare-time-only open source project).

Manual PlacementTarget is one of the properties I don't support yet, or at least has issues when deviating from the default setting.

However, if you dive into the code, it should be fairly easy to add this functionality, but I just lack the time at the moment to do so myself.

If you really need this functionality, I'd suggest you create a fork, try to fix/implement it, and send me a pull request for the solution that worked for you.

Otherwise, you'll have to wait a bit longer I fear..

Best regards,

Xavier

New Post: ToolTip Placement not working as expected

newc1 — Mon, 10 Oct 2011 19:37:04 GMT

Hi,

I am trying to implement the tooltipservice/tooltip using any placement other than Mouse and no matter what properties I set the tooltip is always displayed in the top left-hand corner of the screen i.e. 0, 0.

Pulling the source code into my solution I can see that the placement target is always null, regardless of how it is set within the XAML, and hence the PerformPlacement() method is always coming back with zero x & y values to set the offsets. Using Mouse placement works as expected.

Can someone please advice what I am missing as I asumed placement would work exactly the same as the standard controls.

Thanx,

Chris

New Post: Using with 3rd Party Libraries

ronakce — Fri, 15 Jul 2011 17:58:55 GMT

Hello Xavier,

well this is not working in case of Telerik RadScheduleView Control but it used to work in radScheduler Control.They also told me setting ToolTipTemplate Property of ScheduleView Control to x:null cancel microsoft toolTip and i can use third party but its not working

Basically a RadScheduleView Control is newer version of RadScheduler Control which will eventually go away so i need to upgrade to new Control everything working except the default ToolTip behaviour which i want to have around 5 min.

do you have any inside ?

Thanks

Ronak

XavierDecoster — Wed, 15 Jun 2011 18:03:50 GMT

Hi Ronak,

At first sight, that looks correct to me.

I do hope the Telerik internals don't try to manipulate it based on the Silverlight built-in ToolTipService classes.

Let me know how it turns out ;-)

Cheers,

Xavier
