@Miosss in regards to the popup box that sort of makes sense, the VS designer has historically been a pain to work with. What version of Visual Studio are you on? I know some of the later version (16.8+) have had some significant rework and it may be worth taking another stab at addressing the design time of the controls.

For the second issue that sounds like a bug, do you mind opening an issue for it?

Miosss
@Miosss
@Keboo yup, the designer can be problematic, but this also occurs during runtime - debugger complains about it in binding errors
@Keboo but what should I expect about DataContext in PopupBox? should it inherit parent DataContext? should RelativeSource be obtainable in it? or is it completely detached from the visual hierarchy
Kevin B
@Keboo
@Miosss good question, i would expect it to match the behavior of the normal WPF Popup control (since PopupBox is just a fancy wrapper of a ToggleButton and a Popup), but I am not sure what that behavior is.

@KatoFett
Hello. How do I change the style of a PopupBox's ToggleButton? I want to apply a certain style to it and have text as opposed to an icon. I've tried tampering with the ToggleContentTemplate property and while it looks correct, I get runtime errors when I click. What's the best way to go about this?
KamilGadawski
@KamilGadawski
I need help. I have this code var service = new ItemMenu ("Service", menuService, PackIconKind.ApplicationSettings); and I need to set the icons. I don't know where to look for the icons defined in PackIconKind class. Unfortunately there are no equivalents from the above mentioned class on the website

@Keboo How are the .props files used? I don't see them imported
oh, it is implicit

Hello everyone! Happy New Year, I wish you all the best! Is there any way to limit WPF MaterialDesign TimePicker to only 30 minute intervals. For example, only 7:00, 7:30, 8:00... are possible choices, nothing in between? How to do it? Thanks in advance!
Trần Quảng Dũng
@ctdungqs
Hello
Vasilije Bursac
@VasilijeBursac
Can somebody help me with this please?
I tried to find where in implementation of TimePicker I should redefine it, but there is so many classes....
Kevin B
@Keboo
@KatoFett you can do that by setting the ToggleContent. I have an example of that here
Kevin B
@Keboo
@KamilGadawski there are two easy ways to view the icons in this library. The first is by going to: https://materialdesignicons.com/ the second is within the demo app there is an icons page where you can see all of them.
@jespersh I assume you already found them but there are a couple magical file names that get automatically picked up. https://docs.microsoft.com/en-us/visualstudio/msbuild/customize-your-build?view=vs-2019
@VasilijeBursac there is an open issue #1035 for that, but nothing there right now
Kevin B
@Keboo
As for the files to modify. XAML templates/style for the TimePicker can be found here. The control itself is here. I suspect you will also want to look at the clock control as well. Its XAML is here and the code behind for it is here
Vasilije Bursac
@VasilijeBursac
@Keboo Thank you very much for your response! I will check these links out and try to make it work!

@artipo
Hey @Keboo , I think that that #2170 can be close now that you have merged my pull request (MaterialDesignInXAML/MaterialDesignInXamlToolkit#2192)
Drise13
@Drise13
@Keboo is there a ways to target a DatePickerTextBox and set it to read-only?
same for the time picker
Drise13
@Drise13
I want to be able to only allow a user to use the picking part and not be able to hand edit the date/time
Kevin B
@Keboo
@Drise13 yes but it is not really intuitive. In the templates it uses the DynamicResource to look up the style for the TextBox. This subtlety gives you an injection point to insert your own style. As long as you base your style on the original one it lets you toggle stuff. Something like this:
<DatePicker
    Width="100"
    materialDesign:HintAssist.Hint="Pick Date"
    Style="{StaticResource MaterialDesignFloatingHintDatePicker}">
    <DatePicker.Resources>
        <Style x:Key="MaterialDesignDatePickerTextBox"
                BasedOn="{StaticResource MaterialDesignDatePickerTextBox}"
                TargetType="{x:Type DatePickerTextBox}">
            <Setter Property="Background" Value="Red" />
        </Style>
    </DatePicker.Resources>
</DatePicker>

Is it just me? The latest Master branch having compilation errors
Andrey Nasonov
@Erapchu
Hi to all! How can i increase performance when drawer host is used in window? I use drawer host in my window and it's looks like in main WPF demo app. I compared sliding of drawer host (from the left in my case) when window doesn't have any controls inside - it's very smooth and when window have many other controls like buttons, datagrids, etc. - it's not very smooth and lagging.
Kevin B
@Keboo
@jeeshenlee_twitter the master branch appears to be compiling just fine for me. What issues are you seeing?
@Erapchu there are lots of things that can affect performance, especially if there are lots of controls that are being rendered. Are you able to provide a sample that shows the issue?
@Ezario in general unsubscribing from event handlers is done in C# by simply using the -= operator. You can see some examples and documentation here
Evgeniy
@Ezario
@Keboo Here is a video with a visual explanation of the problem https://youtu.be/DsFlfLZDz7Y. I solved the problem with DialogOpen using DialogHost.DialoOpenAttached, but closing after some time is obtained only through DialogHost directly and I would like to solve this problem, since I did not find an unsubscribe from the event handler in the documentation, because I can not understand which field should be used to unlink xD
Andrey Nasonov
@Erapchu
@Keboo this is not an issue i think on low-performance PC (Nvidia MX150 - notebook and Intel integrated graphic). I just disable animation for opacity in drawer host by creating a new template for this control. And i added duration="0" when going to state "AllClosed". I really need very fast, simple and beautiful (thanks for material design in XAML), but when i use datagrid stretched in window with data (>200 rows) and 7 buttons + some other controls and maximize or stretch window on two screens (just for test) - the window area has increased, then i click on button that open left drawer panel - it's lagging. By disable animations i've achieved my purpose - left drawer panel sliding animation is not lagging so.

@Ezario
Hello guys. How can I extend this ListView.GridView? Because I have a lot of free space on the right and I want to stretch it to its full width. https://imgur.com/a/iSIhabz

@wjax
Hello all. I am a user of this wonderful library for some years now. Thanks for the work because it is just great!
I wanted to know if the library is being ported to .net5
and if you have any ETA... I am migrating a .net framework to .net core or .net5
Thanks again
Jesper Hansen
@jespersh
@wjax I already use it with .net5, so go ahead with using it now

Hi, I am trying to make a reusable "materialDesign:DialogHost" for a Yes / No confirmation Dialog. The only thing that would change on the control are the two texts inside two TextBlock. And I want to call it from the ViewModel and get the Yes / No result.
I followed the example called "DialogHost.WithResult" but it uses

<materialDesign:DialogHost.DialogContentTemplate>
    <DataTemplate DataType="system:String">
                <StackPanel Margin="20">
                    <TextBlock Text="{Binding}" />
                </StackPanel>
    </DataTemplate>
</materialDesign:DialogHost.DialogContentTemplate>

wich allow to pass only one string from the ViewModel.

So is it possible instead to make a reussable DialogHost and instead of setting the DialogContentTemplate with a string we pass two strings directly to DialogContent ?

Amrani
@AmraniRiyad
I could use the Tag property on the DataTemplate but it is not a clean solution.
Amrani
@AmraniRiyad
I don't know why I didn't think about it, I will just use a DataTemplate with a ConfirmationViewModel as DataType
Andrey Nasonov
@Erapchu

@AmraniRiyad Hi! You can create your own user control. For example
Code-behind:

var myUserControl = new MyUserControl("myFirstString", "mySecondString");
var result = await MaterialDesignThemes.Wpf.DialogHost.Show(myUserControl);

Custom user control's textblocks should binds to those strings.

<TextBlock Text="{Binding Text1, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:MyUserControl}}"/>
<TextBlock Text="{Binding Text2, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:MyUserControl}}"/>

In MyUserControl view (xaml.cs):

public string Text1 { get; }
public string Text2 { get; }

In main window just remove data content template.

@AmraniRiyad
@Erapchu Thank you 😉 this is exactly what I ended up doing when I need to call the DialogHost from code behind.
And to call it from a ViewModel I added my UserControl to a DataTemplate.
    <DataTemplate DataType="{x:Type toolsViewModels:ConfirmationDialogHostViewModel}">
        <controls:ConfirmationDialogHost HeaderText="{Binding HeaderText}" Text="{Binding Text}" />
    </DataTemplate>

Hello, im trying to override the default style of buttons but no matter what I put in MaterialDesignThemes.Overrides.xaml it does not change anything. Just for testing I have:

    <Style TargetType="{x:Type Button}" BasedOn="{StaticResource MaterialDesignRaisedButton}">
        <Setter Property="FontFamily" Value="Segoe UI" /> 
        <Setter Property="FontSize" Value="26" />
    </Style>

I also tried overriding other controls but nothing changes. The only thing I got to work is the example from github wiki:

    <Style BasedOn="{StaticResource MaterialDesignButtonTextBlock}" TargetType="{x:Type TextBlock}">
        <Setter Property="FontSize" Value="24" />
    </Style>

Any ideas why nothing works but the TextBlock? Im also using MahApps if that changes anything.

Yoooi0
@Yoooi0
oh, its probably because i do <Button Style="{StaticResource MaterialDesignRaisedLightButton}" ...?
man, i love wpf styles so much

Hey guys, can someone help me with this issue MaterialDesignInXAML/MaterialDesignInXamlToolkit#2211 ? I assume it is a problem that can solve also the DrawerHost problem if there is DataGridinside @Erapchu.
I tried to measure content in DialogHost and then setting the Height and Width of _popupContentControl I also tried to disable the animation but it still does not resolve the issue, showing the dialog is slow if the DialogContent changes.

Note: I am using the MaterialDesignEmbeddedDialogHost style

Andrey Nasonov
@Erapchu
@AmraniRiyad no problems) Nice iOS - style mockup! You may also decrease thickness between buttons (from 2 px to 1 px).
Andrey Nasonov
@Erapchu
@Yoooi0 Hello! You may create your own button style with key property
<Style TargetType="{x:Type Button}" x:Key="MaterialDesignRaisedOversizedFontButton" BasedOn="{StaticResource MaterialDesignRaisedButton}">
    <Setter Property="FontFamily" Value="Segoe UI" />
    <Setter Property="FontSize" Value="24" />
</Style>
<Button Style="{StaticResource MaterialDesignRaisedOversizedFontButton}">
    <TextBlock Text="ABC"/>
</Button>
