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>
-= operator. You can see some examples and documentation here
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 ?
@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.
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.

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
<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>
@stany9g Hi! I can replicate you issue. It's because UI thread try to redraw all rows and columns controls inside DataGrid.
My case was when i try to show left dialog panel over the datagrid, but not the datagrid inside dialog content. When you re-set your UserControl (even if it was initialized) in dialog host, this control redraw what you past in it. Redraw all rows is a costly operation for datagrid with 1000 rows even if this control is virtualized. You can try to implement this collection if applicable for data grid (for listview or listbox i think yes):
https://www.codeproject.com/Articles/34405/WPF-Data-Virtualization
And you can check that UI thread just draw each row and it's costly operation with Material designed DataGrid.
Try to disable material styles for each sub-elements by merging this resources:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<materialDesign:BundledTheme
BaseTheme="Light"
PrimaryColor="DeepPurple"
SecondaryColor="Lime" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.DialogHost.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>DialogHost.xaml only in your demo app. After that try to open first, then second dialog with datagrids. It should be a little bit faster with default styles.
DataGrid. For now, I have set the MaxWidth and MaxHeight of the underlying PART_PopupContentElement (Card) in the style and removed the VisualTransition with that I reached a quite the "optimization" still not perfect as a just opening the same dialog as when switching between content of dialog. Anyway, thank you for the help I really appreciate your time and effort.
to be more exact, i want to remove the focus/tab navigation dotted border from all controls like buttons, sliders etc.
For example:
<!--In Defaults.xaml-->
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource MyStyledButton}" />
<!--Your style-->
<Style x:Key="MyStyledButton" TargetType="{x:Type ButtonBase}">
</Style>
<!--In app.xaml, merged dictionaries-->
<ResourceDictionary Source="pack://application:,,,/WpfApp1;component/ResourceDictionaries/Defaults.xaml"/>
