✅ How to deserialize JSON in .NET when my base class is generic?

I have a concrete class, ClientEventInfo derived from a generic. So I tried to deserialize a JSON file with System.Text.Json.JsonSerializer.Deserialize<ClientEventInfo>("url"), but I get System.TypeInitializationException. Seems the generic can't be initialized. Is there a way around it? I don't know what's going on here.

❔ Can't get root XAML element of UserControl for binding

I have a user control that declares a property that I need to bind properties of its children to. I was trying "{Binding Property, ElementName=window}" for my binding expression. But that seems to fail. It seems user controls don't have a window element. I tried {Binding Property, RelativeSource={RelativeSource AncestorType=UserControl, AncestorLevel=20}} as well, but that doesn't work either. I don't know why. Can someone help? Technically, UserControl isn't my immediate base class. So I tried the intermediate base class as well, but that didn't work. I also tried the derived class to no avail.

✅ How do you control which WPF property is the default for that class?

Examine the following XAML:

<SomeClass>
  PropertyValue
</SomeClass>
<OtherClass>
  <OtherClass.Property>
    PropertyValue
  </OtherClass.Property>
</OtherClass>

<SomeClass>
  PropertyValue
</SomeClass>
<OtherClass>
  <OtherClass.Property>
    PropertyValue
  </OtherClass.Property>
</OtherClass>

If SomeClass where derived from System.Windows.Controls.Control, the property being set would be Content. But in other WPF classes, it might be something like Text. How do I specify my class's default property? The only thing I can find is for Windows Forms. Google happily found results for the default value, but I don't need that. I want the second example in the source above to resemble the first. In this case, I am deriving from System.Windows.Controls.UserControl, but as an abstract class. I don't want the derived class setting Content as that would mess up the base class.

❔ ✅ WPF Class derivation where both classes have XAML pages

Is it OK for base WPF class to have a XAML page and its derived class to also declare one? So we'd have X deriving from Y with the following files existing: x.xaml.cs, x.xaml, y.xaml.cs, and y.xaml.

✅ Abstract classes as the WPF DesignContext?

Does it matter if the value in d:DesignContext="{d:DesignInstance Type=X}" is an abstract class. I can't get the WPF design to acknowledge my type. I know some of you guys have said not to rely on it, but it does help from time to time and I at least like the design context set. I've tried deleting the bin and obj folders for that project and restarting VS. Didn't help.

✅ Null check not enough to safely convert from nullable enum

I have a class declaring an enum and a nullable value for that enum:

public readonly StdModeTypes? smt;

public readonly StdModeTypes? smt;

I then try to reference that field from a second class:

if(cmodeCur.smt != null)
    mapModesWithStdTypes[cmodeCur.smt] = cmodeCur;

if(cmodeCur.smt != null)
    mapModesWithStdTypes[cmodeCur.smt] = cmodeCur;

Yet even with the null check, the IDE is insisting that smt could be null and won't let me use the value:

Error    CS1503    Argument 1: cannot convert from 'BestChat.IRC.Data.Defs.ChanMode.StdModeTypes?' to 'BestChat.IRC.Data.Defs.ChanMode.StdModeTypes'

Error    CS1503    Argument 1: cannot convert from 'BestChat.IRC.Data.Defs.ChanMode.StdModeTypes?' to 'BestChat.IRC.Data.Defs.ChanMode.StdModeTypes'

What's going on?

✅ WPF MouseOver expansion of item isn't working

I have a window with a bar that needs to hide down to a separator until the user mouses over it or checks a checkbox (which pins the bar to "open"). However, WPF seems to be claiming if the mouse is over the margin for the separator, it's not over the bar. The code is below.

                <Grid
                    x:Name="gridExtended"
                    DockPanel.Dock="Bottom"
                    IsMouseDirectlyOverChanged="OnExtendedToolBarMouseDirectlyOverChanged">
                    <Grid.RowDefinitions>
                        <RowDefinition
                            Height="10" />
                        <RowDefinition
                            Height="{Binding ExtendedToolBarRowTwoHeight, ElementName=window, NotifyOnSourceUpdated=True, NotifyOnTargetUpdated=True}" />
                    </Grid.RowDefinitions>
                    <Separator
                        VerticalContentAlignment="Center"
                        HorizontalContentAlignment="Stretch"
                        Grid.ColumnSpan="25"
                        Height="1" />

                <Grid
                    x:Name="gridExtended"
                    DockPanel.Dock="Bottom"

                        Grid.ColumnSpan="25"
                        Height="1" />

        public System.Windows.GridLength ExtendedToolBarRowTwoHeight
        {
            get
            {
                if(gridExtended == null || chkExtendedToolBarShow == null)
                    System.Diagnostics.Debug.WriteLine("Nulls");
                else
                    System.Diagnostics.Debug.WriteLine($"Extended: {gridExtended.IsMouseDirectlyOver
                        }\tCheckbox: {chkExtendedToolBarShow.IsChecked}");
                return gridExtended != null && chkExtendedToolBarShow != null && (gridExtended.IsMouseDirectlyOver
                    || chkExtendedToolBarShow.IsChecked == true) ? System.Windows.GridLength.Auto : new
                    (0);
            }
        }

        public System.Windows.GridLength ExtendedToolBarRowTwoHeight
        {
            get
            {
                if(gridExtended == null || chkExtendedToolBarShow == null)
                    System.Diagnostics.Debug.WriteLine("Nulls");
                else
                    System.Diagnostics.Debug.WriteLine($"Extended: {gridExtended.IsMouseDirectlyOver
                        }\tCheckbox: {chkExtendedToolBarShow.IsChecked}");
                return gridExtended != null && chkExtendedToolBarShow != null && (gridExtended.IsMouseDirectlyOver
                    || chkExtendedToolBarShow.IsChecked == true) ? System.Windows.GridLength.Auto : new
                    (0);
            }
        }

What's going on? It should work so that the bar stays open if the mouse is anywhere over the bar, not just the separator.

✅ WPF trees with some items that can't be selected

I'm building a UI with a tree view where some items exist only to group children. The tree will function as a kind of vertical tree control. When most items in the tree are selected, I'll show a control next to the tree. But the items that are only groups don't have a control to show. So I don't want to allow their selection. How do I pull that off?

✅ WPF TreeView only shows icon and only for the root item

have a tree declared with the following XAML and added from code behind a single item for the root. The root item does have children and a name for each item. But nothing appears beyond a single icon. XAML is reporting no binding failures. I've put breakpoints in for the Children, LocalizedName, and LocalizedLongDesc properties, but of those, only Children is called. What's going on?

✅ Representing an ongoing conversation in XAML and recording it

I'm working on an application in WPF that will show on going conversations much like what you see here. The conversation could go back in history infinitely far back in time (or at least to when it started). I also want to save it to a file. As posts in the conversation get older, it might be worth allowing garbage collection to remove them from memory until the user tries to scroll that far back. I also want a log file for the user to browse and search, if desired, with tools like GREP or PowerShell. Unfortunately, I don't think a human readable format will store enough information. So I may need a JSON log as well that I'd reload conversations from. All this needs to be shown with XAML. If the conversation is too short, I'd like some filler for the space above (below?) the existing posts until the posts fill the window. Any suggestions on how to implement that?

✅ How do I specify custom base class for user control?

I declared a custom base class derived from UserControl. Now in a second assembly, I need to derive from that. The base class doesn't provide a XAML page. Instead, the derived class would. So MyCtrl is derived from MyCtrlBase which in turn derives from UserControl. How do I specify that in the XAML? I tried the following, but it didn't work. Seems the designer doesn't see my custom base class.

The original plan was to declare it in the XAML, but I haven't figured out the equivalent syntax. Can someone tell me what I'm doing wrong? I tried both NotifyOnTargetUpdated as shown above and NotifyOnSourceUpdated. My orignal impression was the latter is for when the control needs to be notified the source has changed. But after reading the documentation, it looks like it's the other way around. With Data.NetworkMgr.mgr, Data is a namespace, NetworkMgr is a class, and mgr is the static instance of Data.NetworkMgr.

❔ DataGrid hyperlink cells without a Navigation Window

My dialog isn't a Navigation Window. But it does have two DataGrid instances each of which has DataGridHyperLinkColumn. Since I don't have the navigation window, how do I handle the hyperlink's Click event?

❔ Does System.Text.Json.JsonSerializer allow members to be serialized or do I need properties?

The problem is that my properties commonly have set accessors that do things like mark the item dirty. You can't have a property with both set and init, or am I misunderstanding something?

❔ d:DesignInstance errors on my forms' root element

I have some in my WPF forms (two of them). It's spitting out some errors that look like bogus. Can someone look at them and tell me what's going on?
