I'm working on a Leadingicon for the Button control and it's working fine in runtime, but the XAML designer is showing me strange behavior. I guess it has something to do with me overriding the ContentTemplate

This is in runtime (don't mind the Flat and Outlined style, it's still a WIP)
In the XAML designer, I get this
image.png
So it seems like the designer can't resolve the Icon and the visibility property I have set on the button
any thoughts?
<wpf:PackIcon
    x:Name="LeadingIcon"
    Margin="0 0 8 0"
    Kind="{Binding Path=(wpf:ButtonAssist.LeadingIcon), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}}"
    Visibility="{Binding Path=(wpf:ButtonAssist.HasLeadingIcon), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}, Converter={StaticResource BooleanToVisibilityConverter}}"
    VerticalAlignment="{TemplateBinding VerticalAlignment}" />
code from inside the DataTemplate of the ContentTemplate setter

@MichelMichels send like the designer is possibly loading (or holding onto) an older version. Normally when I have seen designer issues with the pack icon it simply does not sure. But the fact it is showing the wrong icon is a little odd
Michel Michels
@MichelMichels
@Keboo yes, it is showing the "Abacus" PackIcon, which is the first one

Hello, I've noticed that the DialogHost adjusts itself upwards in the presence of an onscreen keyboard. This is great! However, it only does it when the app is NOT maximized. How can I make it do so also when maximized?

It is not related to MaterialDesign but if someone can give some light on this one please ? : https://stackoverflow.com/questions/65864630/form-with-validation-of-models-wrapped-in-viewmodels-with-one-to-many-relation

Hi, maybe some margin (DialogMargin ?) is preventing it from moving?

@AmraniRiyad I am not aware of any DialogMargin. But it works in windowed mode :/

hello, "IsIndeterminate" option value of component named UniqueKey="progress_2" need to be change to false.
because if that option was true, that make a 'Material Design Demo' run slow in on 'Progress Indicator' Tab

How do I change the burger icon for the Style = MaterialDesignHamburgerToggleButton? For some reason it is a different size? The middle line is bigger than the top and bottom lol
iDanny
@iDanny07
<ToggleButton
     Margin="24,0,0,0"
     x:Name="LeftMenuToggleButton"
     AutomationProperties.Name="HamburgerToggleButton"
     IsChecked="False"
     Style="{StaticResource MaterialDesignHamburgerToggleButton}" />

In VS it looks normal lol
Kevin B
@Keboo
@alizeynalli_gitlab we would need to see your project to tell. It is difficult to know what the problem is just from that description.
Kevin B
@Keboo
@alphabet1201 Thanks for the heads up. you are correct that indeterminate progress bar can slow down an application due to their constant animation, however in this case that progress bar is meant to show off how an indeterminate progress bar looks. To address the performance of it, I did adjust the size of containing grid as that was also contributing to the slowness.
@iDanny07 possibly a layout rounding issue? I would try setting UseLayoutRounding ="True" on your window
iDanny

@Keboo No that did not help.
Also how would I be able to change the size of the PopupBox icon? (3 vertical dots)
I tried width and height on it but it only changed the container not the icon

I am having a problem with the github version of the material with caret, if I create a TextBox that saves the text of my application, when my application opens with the text in the TextBox the caret is shown at the beginning of the TextBox.

Example that happened to someone else who posted on github

@iDanny07 there is a property on the PopupBox called ToggleContent that can be set to any content that you like. The default is just a PackIcon with Kind="DotsVertical" and a size of 24x24. So if you want to change the size simply set your own PackIcon with your desired size. You can see an example of setting the ToggleContent here.

@pablokentch that appears to be the outstanding bug #1519. Currently there is not a fix for it.

Good morning, I was wondering if there's a setting to fix the following issue with Snackbar? I'm limited to a very tight space and it looks like Snackbar is hardcoded to minimum width
image.png
ActionButtonPlacement="Auto" or "SeparateLine" doesn't fix the truncation. Thank you
Federico Rossi
@artipo
@Keboo I've looked into the #1519 and I think I've found the cause of the bug.
It all boils down to VerticalContentAlignment being set to Top inside TextBox styles.
There's also the ControlTemplate trigger that occur when TextFieldAssist.HasOutlinedTextFieldthat set VerticalContentAlignment to Top.
I would submit a PR to solve this but I fear that setting VerticalContentAlignment to Stretch would cause unwanted behaviour and/or style appearance.
Anyway I'll attach an image showing that with VerticalContentAlignment being set to Top, the underlying TextBoxView doesn't use the entire available vertical space. Since that control is responsible for the CaretIndex change, missing the HitTest cause the use of default CaretIndex position, which is 0.

Hello, I am trying to override "TextFieldCornerRadius" of "MaterialDesignOutlinedComboBox" and I am able to see the change in VS Designer of the user control. But in the designer of the mainwindow and runtime, it fell back to the default style. Really appreciated if you can provide some pointers.

            <Style x:Key="MaterialDesignOutlinedComboBox" TargetType="{x:Type ComboBox}"
                   BasedOn="{StaticResource MaterialDesignOutlinedComboBox}">
                <Setter Property="materialDesign:TextFieldAssist.TextFieldCornerRadius" Value="50"/>
            </Style>

Is there a NumericUpDown control? I see some source that eludes to a NumericUpDown, but I don't see an example in the demos.
Federico Rossi
@artipo
@GnahZn1x I don't think naming your custom style with the base style name it's a good idea. The latter get overridden by yours and this could be the reason why th style seems incorrect at runtime

hi guys, I am using a PopupBox in a CellTemplate for a DataGridTemplateColumn. The PopupBox shows up as expected, but when clicking the Save-Button defined as

<Button Content="_Save"  Command="{x:Static materialDesign:PopupBox.ClosePopupCommand}" />

a get an InvalidOperationException: System.Windows.Documents.Run is not a Visual or Visual 3D

When I use the same PopupBox-XAML-code outside of the DataGrid the button works as expected. Do I need to do something special to get it to work within a DataGrids CellTemplate or could this be a bug?

@GnahZn1x
@artipo thanks for the suggestion. I will take a try.
