Commented Issue: AutocompleteBox not binding half the time [9648]

bleakcabal — Wed, 22 Feb 2012 17:58:46 GMT

When I set the Text property by binding to null value, the next change by binding is not taken into account.

the problem comes from _ignoreTextPropertyChange field in AutoCompleteBox.cs.
When the Text property is changed by code this field is incremented because a TextChanged is fired on the inner TextBox which decrements this counter.
But in case where the new value is null, the TextChanged is not fired and the counter will be decremented next time the value will be changed, but with take care this value.

Is it possible to fix this bug about this counter ?

Sorry for my bad english.
Thank you

Commented Issue: TextBox.Header [9981]

shawnoster — Mon, 20 Feb 2012 19:46:44 GMT

Just a simple thing is going to drive me crazy.

It looks like that the Header property isn't supported by System.Windows.Controls.TextBox! WHY?
But the screen-shot at http://msdn.microsoft.com/en-us/library/hh202916%28v=vs.92%29.aspx claims that there is a Header property for TextBox!?

I am confused ... Also PhoneTextBox does not support a Header property?

See also:

Workaround for headers on TextBox controls:

Is it possible to add a Header property to the textbox control:
http://forums.create.msdn.com/forums/p/76127/576970.aspx

So I am not completely alone with that TextBox.Header question ... But what is the one and only answer for TextBox.Header? Even the MSDN article "TextBox Control Design Guidelines for Windows Phone" shows a screen-shot of TextBoxes using Header and pointing to System.Windows.Controls.TextBox that control does not support it!?

The workaround by "EGL" looks nice but how to define the InputScope (for example when I just need "Numbers") in XAML? Thank you for bringing some light into the dark ;-)

Comments: ** Comment from web user: shawnoster **

The screenshots that you link to aren't showing a TextBox with a Header property, it's a TextBlock with a TextBox underneath grouped together with a StackPanel. This is a pretty standard pattern for many control libraries, you have discreate controls and compose your UI from them (a Label and a TextBox).

That said it sounds like you'd like a "HeaderedTextBox" that has a header so you can easily recreate the standard Metro UI with proper margins and color. One downside of providing such a control is that internally it'll use a StackPanel and more than likely your outer containter will also be a StackPanel and you'll end up exploding your element count. Something like this:

FourSpotProject — Sun, 19 Feb 2012 20:23:15 GMT

It looks like using the below combination of transition, caused some glitches to the pages, when u switch to the application, using the Mango multi tasking. Can easily be recreated in the sample that is provided with the toolkit.

Comments: ** Comment from web user: FourSpotProject **

I think I have to adjust my comment somehow: what I wrote is only partly right.
The real problem is that when leaving the app, the transition is started but never completes (because of the app going into dormant state). And when one navigates back then, the wrong transition is executed (the backward-out one instead of backward-in), which leads to different types of transitions being executed.
I've eventually fixed this bug by adding

if (e.Uri.OriginalString == "app://external/") return;

after

FlipPresenters();

in TransitionFrame.cs.

Hope this helps.

Created Issue: LongListSelector unspecified error occurred [10404]

I am using LongListSelector in my project.
When I am tap on the group item unspecified error occurred. And it's occurred when I am invoke DisplayGroupView(). I do not understand why it happens. Why it's happens? Explain me please.
Thanks.

Created Issue: LongListSelector places items in wrong groups if groups are created initially empty [10399]

fleetingshadow — Sat, 18 Feb 2012 02:53:17 GMT

To repro:
Create initial set of grouped items.
Create new groups (empty).
After you create each group add it to a collection.
Now create items in the group.
(Typically, I'm seeing all items ending up at the end).

Workaround: Set DisplayAllGroups to True.

Commented Issue: Error building Silverlight 3d Application from VS2010 template [9613]

When I try to build a new project from the Silverlight 3D application template I get the following error.

Error 1 The project file "..\Silverlight3dAppContent\Silverlight3dAppContent.contentproj" was not found. C:\Users\.....\1cbbbxyx.dji\Temp\Silverlight3dApp.csproj 109 5 Silverlight3dApp

Didn't notice any trouble through installing: VWD 2010 Express, SP1, SL5, SL5Toolkit. However after then installing the Windows Phone SDK (for XNA) and reapplying SP1... I cannot create or open solutions containing content projects. The template is available, but I receive an error message like the one pictured above.

Commented Issue: does the Silverlight 5 Toolkit work with web developer express 2010? [9624]

LiquidAsh — Fri, 17 Feb 2012 17:10:50 GMT

after installing the Silverlight 5 Toolkit September 2011, the templates do not show in VWD express 2010 SP1. I can see the zip files there in C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\VWDExpress\ProjectTemplates\CSharp\Silverlight\1033 but they do not show up in the list of projects to create. likewise, when i try to run one of the samples, i get errors like "solution folders are not supported in this version of the application", And for content project: "This project type is not supported by this installation." this is a pretty fresh install of Windows7x64sp1 and visual studio express. i installed the toolkit after the silverlight 5 RC developer, and am able to make SL5 apps. tried un-installing the toolkit and re-installing on 2 different computers with the same result. Am i missing something?

thanks, chris.

Have you also installed XNA Studio 4? I am also trying to use Visual Web Developer 2010 Express. After installing SP1, SL5, SL5Toolkit, Windows Phone SDK (for XNA), and then reapplying SP1, I am able to see the templates for project types like Silverlight3D Application, but when I try to create one (or open an existing one) there are errors that seem to indicate that Visual Web Developer 2010 Express does not work with content projects. I'm very interested in hearing whether anyone has been able to make this work.

Created Issue: 2 minor fixes [10380]

lloyd — Wed, 15 Feb 2012 15:19:10 GMT

2 fix I had to do..

1. ListPicker, when navigating to a page with a list picker setup with databing I got a spurious error 'selected item must be valid'
even though ItemsSource and SelectedItem where set in this order from the same (binding) source, at some stage the value set to null (from the right value) because the Itms property hasn't been populated by the ItemsSource property yet.
Fixed with this code:
private void OnSelectedItemChanged(object oldValue, object newValue)
{
if (null == Items || Items.Count == 0)
{
if (null == Template)
{
// Can't set the value now; remember it for later
_deferredSelectedItem = newValue;
return;
}
else
{
if (newValue != null)
throw new InvalidOperationException(Properties.Resources.InvalidSelectedItem);
}
}

2. In some instance in PhoneTextBox my text is grayed / same as hint, although it's perfectly valid!
I update UpdateHintVisibility() to set the foreground color in all case, as in:
private void UpdateHintVisibility()
{
if (HintContent != null)
{
if (string.IsNullOrEmpty(Text))
{
ActualHintVisibility = Visibility.Visible;
Foreground = ForegroundBrushInactive;
}
else
{
ActualHintVisibility = Visibility.Collapsed;
Foreground = ForegroundBrushEdit;
}
}
}

Commented Issue: ChildWindow allow reentrant calls to Close, leading to broken state [8497]

faccipieri — Wed, 15 Feb 2012 15:04:08 GMT

Repro:

1) Create a ChildWindow
2) Add a handler for Closed (ClosedHandler) that calls Close again on the ChildWindow

Expected: the 2nd close would error out or be a no-opt
Actual: since _isOpen = false is set *after* the closed event is raised, the logic decrementing OpenChildWindowCount is called twice, resulting in a negative count.

Result: the RootVisual stays disabled, which really sucks.

Suggestion: set _isOpen to false before raising the Closed event.

Created Issue: AutoCompleteBox issue in SLXNA Project [10370]

AndriMirandi — Tue, 14 Feb 2012 04:13:49 GMT

Hi All,
I`m using Windows Phone Toolkit - November 2011 edition, and Windows Phone SDK 7.5 which supports a new kind of Project called SLXNA (Windows Phone Silverlight and XNA Application)
If I use an AutoCompleteBox, when I start entering text, the DropDownList wont show, but if I activated the IsTextCompletionEnabled to true, the text selection is shown, so the databinding is working fine, but the dropdownlist isn't shown.
Has anybody find a workaround or a patch for this ? thanks

Commented Issue: LockablePivot restores pivot headers so that they overlay on top each other [9619]

BorisT — Mon, 13 Feb 2012 22:33:17 GMT

The problem occures when you lock the pivot during the transition (in my case I lock pivot during the pinch event, and pinch can start before pivot transitioning animation is over). I suspect originalX is captured incorrectly while pivot transition animation is in progress and that makes LockablePivot to restore pivots items so that headers overlap each other.

Workaround: in the LockablePivot.cs comment out all the code taht deals with originalX.
In fact, in my case I don't even need any animation since I just need to avoid pinching resulting in an acidental pivot switching. So I commented out FadeOutHeaders() and FadeInHeaders completely. Would've been nice if there was a boolean property on the pivot to enable/disable the fade in/out animation.
Comments: ** Comment from web user: BorisT **

i'll second this.
Bad error :/
