Re: Disable ComboBox Hyperlinks

What's wrong with binding the IsEnabled property on the Hyperlink to a property on your view-model?

Re: Disable ComboBox Hyperlinks

It would need to be bound to a property on the entity - except there is no entity. I'm loading the combo box with enums.

If it's not broken, fix it until it is.

Use a DataTemplateSelector as the ComboBox.ItemTemplateSelector.
The SelectTemplate() method will be passed each item, (the enum in your case).
Select a data template specific to each case you want.

WPF DataGrid - Stretch Row Details Vertically

Get MainWindow from Executing Assembly

I've got Row Details section in a DataGrid. The DataGrid's width is set to 1500, yet the row details content stretches off the right side of the grid. Here's all the XAML.

Here's a screen shot

How do I make the Row Details content wrap?

Re: Get MainWindow from Executing Assembly

23-Jul-21 8:59

Is it possible to get the MainWindow from the exeucting assembly?

I am opening a dialog contained in another assembly and in that dialog I want to set the Owner to the Main Window of my executing app.

I know in the dialog I can do

var callingAssembly = Assembly.GetCallingAssembly();

which gives me the assembly of my main app. But Can I then somehow get access to that assembly's Application.Current.MainWindow?

What I'd really like, in my dialog, is something like this:

public MyDialog()
{
    var window = //??? Get the calling assembly's Application.Current.MainWindow

    this.Owner = window;
}

Thanks!

Assuming you're not using a separate AppDomain to load the assembly, Application.Current.MainWindow should still work from the other assembly.

Not sure why you would not use Visual Studio Community Edition to manage/edit your WPF files and projects. that has everything, and is free. Visual Studio Community 2019 - Free IDE and Developer Tools[^]

But, if Visual Studio is out of the question, then there is always this:

Building WPF Applications in Visual Studio Code with PowerShell[^]

if you just want to edit the actual xaml files then Visual code should be good.

both are free as far as I know.

Looks like the SmithHtmlEditor project has moved to GitHub:
GitHub - adambarath/SmithHtmlEditor: The source code is about html editor usage in WPF application.[^]

It doesn't seem to have much detail there, and is still pointing to the (now defunct) CodePlex archive for more information. But the GitHub version seems to have been updated more recently.

There don't seem to be a huge number of other options - there's this one[^] from 2015, and this one[^], also from 2015, but beyond that Google is only suggesting commercial products.

I've not tried it, but you might have better luck embedding a WebView2[^] control and using a Javascript HTML editor.

I considered the CodeProject one but settled on the smithhtmleditor. Seems to be working Ok, a little quirky with fonts but other than that fairly easy to use. All I need is some basic editing for keeping notes in the app I'm working on.

Installing Test Mode vs Production Mode

Kevin Marois19-Jul-21 8:55

19-Jul-21 8:55

I'm working on a WPF app that we now want to have a 'Test Mode'.

Right now, I have an 'IsTestMode' property in the app.config. If I set it to True, then the login window's border is red, and there's a red TEST MODE banner across the top of the main window. The Test Mode copy is installed in a different location then the production copy.

In the code behind of the Main Window I have:

Uri iconUri = null;
if (AppCore.IsTestMode)
{
    iconUri = new Uri("my_test.ico", UriKind.Relative);
}
else
{
    iconUri = new Uri("my.ico", UriKind.Relative);
}

this.Icon = BitmapFrame.Create(iconUri);

This changes the Taskbar Icon, not the desktop icon

This all works fine.

Now I want to add an installer project, but I'm stuck on how to make the Test Mode changes during installation. I'd like to do the following during installation and not let the user change them:

Set the installation location
Set the IsTestMode setting
Change the desktop icon.

Can anyone shed some light on how to do this?

Thanks

Routed Event Args Null

Kevin Marois28-Jun-21 16:28

Re: Routed Event Args Null

28-Jun-21 16:28

I have a user control with a custom Routed Event. I'm trying to pass event args:

public class NavigationViewFilterEventArgs : RoutedEventArgs
{
    public List<LookupEntity> StatusFilters { get; private set; }

    public List<LookupEntity> FilterItems { get; private set; }

    public NavigationViewFilterEventArgs(RoutedEvent e, List<LookupEntity> statusFilters, List<LookupEntity> filterItems) :
        base(e)
    {
        StatusFilters = statusFilters;
        FilterItems = filterItems;
    }
}

Here's the UserControl code behind:

public static readonly RoutedEvent FilterExecutedEvent =
            EventManager.RegisterRoutedEvent("FilterExecuted",
            RoutingStrategy.Bubble,
            typeof(RoutedEventHandler),
            typeof(NavigationView));

public event RoutedEventHandler FilterExecuted
{
    add { AddHandler(FilterExecutedEvent, value); }
    remove { RemoveHandler(FilterExecutedEvent, value); }
}

private void RaiseFilterExecutedEvent()
{
    var args = new NavigationViewFilterEventArgs(FilterExecutedEvent, StatusFilters, FilterItems);
    RaiseEvent(args);
}

The control is on the Main Window:

<ctrls:NavigationView Grid.Row="7" 
                        Caption="Companies"
                        StatusFilters="{Binding DataContext.CompanyStatusFilterItems, 
                                                ElementName=window, Mode=TwoWay, 
                                                UpdateSourceTrigger=PropertyChanged}">

    <i:Interaction.Triggers>
        <i:EventTrigger EventName="FilterExecuted">
            <i:InvokeCommandAction Command="{Binding DataContext.CompanyFilterExecutedEventCommand, 
                                                        ElementName=window}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>

</ctrls:NavigationView>

And finally the handler in the Main Window view model:

private ICommand _CompanyFilterExecutedEventCommand;
public ICommand CompanyFilterExecutedEventCommand
{
    get
    {
        if (_CompanyFilterExecutedEventCommand == null)
            _CompanyFilterExecutedEventCommand = new RelayCommand<NavigationViewFilterEventArgs>(p => CompanyFilterExecutedEventExecuted(p), p => CompanyFilterExecutedEventCanExecute());
        return _CompanyFilterExecutedEventCommand;
    }
}

private bool CompanyFilterExecutedEventCanExecute()
{
    return true;
}

private void CompanyFilterExecutedEventExecuted(NavigationViewFilterEventArgs args)
{
}

When I run this and click the button, the event reaches the Main Window VM's CompanyFilterExecutedEventExecuted method, but the param is always null.

I could use some help here.

How to change background color in combobox in code behind?

28-Jun-21 22:34

The problem isn't that the EventArgs object is null; it's that the EventArgs object isn't being passed as the command parameter to your RelayCommand.

If you're using the Microsoft.Xaml.Behaviors.Wpf[^] package, you need to set PassEventArgsToCommand="True" on your <i:InvokeCommandAction> element.

If you're using Prism, that will pass the event args automatically if the command parameter is not set. But that would use a different namepsace prefix on the InvokeCommandAction element.

As it is now, the textbox will change it width but not it's height, due to it being set to 225 in the grid definition. However, I am unsure how to set the grid so that it will take up the space but leave the bottom controls visible. Basically I want it to be as it is now but able to resize.

I am thankfull for any suggestions.

Have a nice day!
