Hi gang, I'm using <DataGrid ... /> in what I think is a fairly stock configuration and selecting isn't working as I'd like. A row is only selected when a column like a textbox or dropdown is clicked, not when the mouse is left clicked anywhere on the row. The behavior I'm trying to engage is for a doubleclick to execute a command (which works fine) except when the code runs, SelectedItem is only set when the click happens over an element like a textbox or combobox (probably others, I haven't done the exhaustive investigation). Suggestions/

I am performing a fairly large refactoring/reorg on my application which uses MaterialDesignInXaml. I currently use my own ad-hoc lightweight MVVM implementation. I am considering migrating over to use ReactiveUI, but I was curious if there are any incompatibilities or problems that might be introduced when changing to a completely different binding convention. Is anyone here "all-in" on MaterialDesignInXaml and RectiveUI? Or does this require some fiddling to make it all work?

@JinZeping a couple follow up question? which input method program are you using in those screenshots? Does it work in the demo app if you scroll all the way to the right to SAMPLE 5 (this sample uses a different dialog that is not in a popup)?

@Keboo
@howardalt I might need to see some XAML but based on your description I suspect you are clicking on the section of the row that is to the right of your columns (where there is no column). Unforuently this is actually normal WPF behavior. If you test without material design you will notice that the row selection on the default DataGrid only shows the row selection through the cell that are in column, and no row selection outside of that. The difficult part here is the DataGrid does not raise the events needed to make this work (if other people find a work around I would love to hear about it). The easiest "fix" is to simply set the width of one of your column to fill the extra space (Width="*"). Alternatively you can throw in an extra column for not other purpose than to fill the remaining space (though depending on your UI this may or may not work).
@Awsmolak I have used ReactiveUI on a few small things, never on a major project, but I have not run into any incompatibility. This library aims to be agnostic of any MVVM library (or even no MVVM if people want to go that route), so if there are issue please raise them.

@Keboo Thanks! Will do.

@howardalt
@Keboo ahhh yes, awesome, i'll give that a try, thanks for the thought!

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

@JinZeping
@Keboo The SAMPLE5 dialog can work, Thank you very much!

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
Shreyasj96
@Shreyasj96
<ListView ItemSource={Binding YourItemSource}">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Label Content="{Binding YourLabelConent}"/>
<Button Command="{Binding YourButtonCommand}"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

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?
