New Post: Problems with IntegerUpDown.

January 3, 2016, 7:47 pm

Hello,

I've been searching for a good numeric up-down control for years. Every implementation I've found on the internet has been full of bugs with various issues, which is very frustrating. Up until now I've been using a custom modified version of something I found, with various bug fixes and feature additions, but it's still far from perfect...

Today, I discovered the IntegerUpDown in the Extended WPF Toolkit. It looks pretty good, but unfortunately I found two issues within seconds of using it. :(

1. After typing in a value greater than the "Maximum" value, it automatically cuts off digits from the end until it's a low enough number. This behaviour seems very odd to me, as I would expect it to simply change to the maximum value if it's above that (i.e. capping it). This issue also applies when setting values below the minimum. Is there any way to get the behaviour I want?

I found a post in the comments on the IntegerUpDown page saying that it would be fixed in version 2.0, but that was back in 2013...

2. The context menu for the control looks... wrong. It has inconsistent spacing. What's causing this? How can I fix this? See the following screenshot:

Could you offer any help?

Thanks in advance,
Delia.

New Post: Toolkit wizard prevent closing OnFinish

Hi..
i am using the wizard to get some input from the user.
Now, in the last page, i need some input from the user...
the input will not be check for correctness untill the user clicks on the Finish button.
<xctk:Wizard x:Name="wizard" FinishButtonClosesWindow="True" HelpButtonVisibility="Hidden" Finish="WizardOnFinish">
private void WizardOnFinish(object sender, RoutedEventArgs e)
        { 
              bool b = UserEnteredCorrectData();
              if(!b)
             {
                 // DONT CLOSE THE WIZARD WINDOW
             }         
}
The problem iam having is, wheter i use 
        e.Handled = false;
or 
        e.Handled = true;
the wizard is closing whenever the user click on the Finish button in the wizard.

My question is:
how can i prevent the window from closing as long as the input is wrong?
i dont want to set the CanFinish property to false, i want the user to click on the Finish button and then i want to evaluate the user`s input..
any ideas?

Thanks in advance

Update:

I managed to fix the first issue by setting the "ClipValueToMinMax" property to true. I'm still not sure why this wasn't the default.

I'm still having trouble with the second issue though, and would really appreciate some help. I don't understand why it looks so broken. The default context menu on the normal TextBox control looks fine - it's only broken, with the first item indented, on the xctk:IntegerUpDown control. I tried replacing the context menu with a custom one, and it's still broken there. Incidentally, I noticed that if I use the same custom context menu on the regular TextBox control, then right-clicking on the xctk:IntegerUpDown control breaks the context menu everywhere, even on the regular TextBox.

Any ideas? I've tried removing styles and looking at the template and I'm stuck.

Okay, I finally managed to track down the issue with the context menu.

It seems that it is being caused by the default TextAlignment="Right" setting on the IntegerUpDown style. Removing this setting fixed the issue, but it also results in the content being left-aligned instead. I googled this issue and found the following forum post confirming the problem (which also applies to the regular TextBox control):

https://social.msdn.microsoft.com/Forums/vstudio/en-US/732a73d0-85fa-40e9-ad87-fb2c03452c75/wpf-textboxs-textalignment-changes-its-default-context-menu-items-alignment-as-well?forum=wpf

Unfortunately, their solution is to set the HorizontalContentAlignment to "Right" instead. This works fine with the regular TextBox control, setting the content to be right-aligned without mangling the context menu. However, it doesn't work at all for the IntegerUpDown control.

I wasn't able to get a working fix for this, so for now I'll just use TextAlignment="Left" as a workaround. This is fine for my current project, so I'm done here. I'll submit this as an issue, and hopefully this bug will be fixed next time I come back to it.

Thanks!

New Post: Color Picker menu not opening

Hi,

You you say "is set to always stay on top", do you mean you are using a Window with it property TopMost = true ? Or a big Panel.ZIndex ? I cannot reproduce the issue.

Selecting a color will always close the ColorPicker, except when in the Advanced part of the ColorPicker. But Clicking the AdvancedButton should switch to the Advanced part of the ColorPicker.

What version of the Toolkit are you using ?
What version of Windows are you using ?
Can you send a sample of the problem.
Thanks.

  1. You got it. Using "ClipValueToMinMax" to true will "cap" to the Maximum and Minimum values. This is not the default behavior because this property has been introduced later and we didn't want to change the current behavior of the NumericUpDown.
  2. If I create a new project, add an IntegerUpDown and right click on it, the contextMenu contains text correctly aligned.
<xctk:IntegerUpDown Value="36"/>
What version of the Toolkit are you using ?
Can you submit a sample ?
Thanks.

New Post: CheckListBox filtering with ICollectionView

January 7, 2016, 3:35 pm
$

The CheckListBox ItemsSource is bound to a CollectionView so I can use a textbox to apply filtering. However, when an item that was checked is removed from the view by the text filter it is no longer checked when the filter is removed and the item returns. Here is how the CheckListBox binding is setup, 'UnitListView' is the CollectionView and CheckedUnits is just a list.
<xctk:CheckListBox Margin="50 5 50 50"
                               ItemsSource="{Binding UnitListView}"
                               SelectedItemsOverride="{Binding CheckedUnits}"
                               Command="{Binding CheckedCommand}"/>
I added the command to determine if it executes when the filter is applied. The result was that it only executes when an item is checked (when I click the item), not when items are filtered. The text filter is straight forward and shown below:
        private bool TextFilter(object item)
        {
            Console.WriteLine(FilterString);
            if (String.IsNullOrEmpty(FilterString))
                return true;
            else
                return ((item as UnitModel).ToString().IndexOf(FilterString, StringComparison.OrdinalIgnoreCase) >= 0);
        }
Any insight into this? I am new to ICollectionView, is there something there that I am missing?

I'm fairly new to WPF. I'm trying to figure out how to alter the style of the Popup is shown. I really only want to change 1 thing: the background brush of the popup - and possibly the border settings. I just want to alter it to have the look & feel of the rest of my application.

Any pointers in the right direction would be greatly appreciated.

Hi,

You need to redefine the template and change the Background/BorderBrush of the ColorPicker popup.
You can find the ColorPicker template in :
-Xceed.Wpf.Toolkit/ColorPicker/Themes/Aero2.Normalcolor.xaml (for windows 8)
-Xceed.Wpf.Toolkit/ColorPicker/Themes/Generic.xaml (for other windows)

Look for
-PanelBackgroundBrush and PopupDarkBorderBrush (in Aero2.NormalColors.xaml)
-PopupBackgroundBrush and ColorPickerDarkBorderBrush (in Generic.xaml)
which are the default Background/BorderBrush colors.

Hi,

The MaterialButton (as well as Material Controls) from the Toolkit are part of the "Toolkit Plus Edition". This means that you need a License Key in order to use them.
What does the inner exception says when you are faced with the exception ?
Is it something like :
"Xceed.Wpf.Toolkit.Licenser.LicenseKey property must be set to a valid license key in the code of your application before using this product. Please refer to the Licensing topic in the documentation for more information on this exception."
If so, please buy the "Toolkit Plus Edition" and set the License key.

The "##INCLUDE_OPEN_SOURCE" tag stands for code that will be executed only on the Opensource version (Toolkit Community Edition). In this case, an image will be shown instead of the control itself. If you use the "Toolkit Plus Edition" (with a license Key), the MaterialToolTip control will be used instead of an image of the control.

Everything works well except this : after typing a new value, this value is lost when going out of the combo.

This is throwing an XamlParseException that says "Failed to create a 'Type' from text 'xctk:MaskedTextBox'. The inner exception says that it is unable to find the type specified.
