@Keboo thanks for the combobox advice, it works; on the other hand, ClassicMode does not work with Filled style

Hi Can you provide some list example?

Hello everyone!!

I have an issue calling a DialogHost from ItemTemplate button

here is some code

              <ListView.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <Button Command="{x:Static materialDesign:DialogHost.OpenDialogCommand}"/>
                        </StackPanel>
                    </DataTemplate>
                </ListView.ItemTemplate>

Said1996

@Said1996

and somewhere out of listview scope I got this

   <materialDesign:DialogHost CloseOnClickAway="True">
       <materialDesign:DialogHost.DialogContent>
           <Grid Margin="20">
               <TextBlock Text="My first Dialog" />
           </Grid>
       </materialDesign:DialogHost.DialogContent>
      </materialDesign:DialogHost >

The problem probably lies that the list item is in another scope where it can't see the dialog Host

the problem is that I don't know the exact syntax to reach it out of listview scope

I ve also tried this

<ListView.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                             <materialDesign:DialogHost CloseOnClickAway="True">
       <materialDesign:DialogHost.DialogContent>
           <Grid Margin="20">
               <TextBlock Text="My first Dialog" />
           </Grid>
       </materialDesign:DialogHost.DialogContent>

       <Button Command="{x:Static 
                materialDesign:DialogHost.OpenDialogCommand}"/>
                    </materialDesign:DialogHost>
                        </StackPanel>
                    </DataTemplate>
                </ListView.ItemTemplate>

Said1996

@Said1996

but the output wasn't as I wanted because it treated each item in the list as a view

Shreyasj96

@Shreyasj96

@Said1996 You can check out the first sample in Dialogs section of the DemoApp.

Said1996

@Said1996

Yes thats exactly the output that i dont want

i want the output to be like the 2nd example

@Shreyasj96

Shreyasj96

@Shreyasj96

@Said1996 You can try Command Binding of the button like so Command="{Binding ElementName=yourOutOfScopeDialogHostName,Path= materialDesign:DialogHost.OpenDialogCommand}". Im not sure if this works tho'.

Said1996

@Said1996

@Shreyasj96 Thanks so much ill give it a shot and tell you the result

Said1996

@Said1996

@Shreyasj96 No, not working

Shreyasj96

@Shreyasj96

@Said1996 Where have you put your dialogcontent?

Said1996

@Said1996

inside dialogHost

I tested the binding, the binding isn't working

Shreyasj96

@Shreyasj96

@Said1996 Then you might have to do it from the ViewModel itself if you are following MVVM or from the code behind by setting the IsOpen of the DialogHost to true.

Said1996

@Said1996

is there any way around that?

Shreyasj96

@Shreyasj96

Can you post the whole xaml?

Said1996

@Said1996

I wrote all the parts thats related to DialogHost ... no other part uses that

the whole problem is that i am binding to a button in a datatemplate so its normally binded sourcelist

and binding to element name could work if we could find the correct path ... I tried your example + path = OpenDialogCommand still no clue

Shreyasj96

@Shreyasj96

@Said1996 It's a bit confusing what you're trying to do and i don't think it can be done the way you are trying to do right now.

Said1996

@Said1996

it's not confusing all I have is a list of where each item contains some labels and a button and i want to open a dialog host when any of those buttons are pressed

that's basic I guess

Shreyasj96

@Shreyasj96

Any progress?

Said1996

@Said1996

ummm no but ill guess ill do it from code behind

Thanks a lot for helping, I guess its the only way now

Hello Guys. Does someone help me to understand why DialogHost.Show is aysnc? When it is not on GUI thread?

Kevin B

@Keboo

@garywu123 unlike the message box (which blocks) the thread, it is async to allow for the UI thread to continue. This allows for things like animations to continue running on the UI thread, while the dialog is shown and provides for a convenient way to return a result from the dialog when it is closed.

Hi all, I try to use PopupBox, though 2 examples from 3.1.2 demo are broken (Buttons->PopupBox->round buttons). Is there way to pass DataContext (even by RelativeSource) to the popup? It is created outside of the visual tree (PopupRoot). It seems to be working (sometimes?), but VisualStudio debugger complains about RelativeSource not being found. So, I am not sure - is it working or not?

ah, and native wpf Popup can use PlacementTarget to bind DataContext to itself, but there is no PlacementTarget in PopupBox

To be more precise - it kinda works, but VS debugger reports binding errors (relativesource not found).

and second question - close command in PopupBox is using RoutedCommand - but I use it in DataGrid header and it triggers DataGridColumn click (I think) which is not in visual tree which throws exception and crashes - System.Windows.Documents.Run” is not Visual or Visual3D.'

Miosss

@Miosss

materialDesign:DataGridAssist.EnableEditBoxAssist="False" fixes the issue, because AllowDirectEditWithoutFocus was in the call stack of this bubbling event; not ideal though

Kevin B

@Keboo

@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

@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

@jespersh

@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!
