Event to Command Behavior Not Working?

[EmberLynn]

I'm trying to use the EventToCommandBehavior on an Entry field. My code is as follows:

I know that TextChanged is the event that fires whenever something is typed into the Entry. However, I cannot get the ToggleIsSubmitButtonEnabledCommand to fire (It does work, I can fire it through a Command Property on a button). Does anyone have any advice as to why the Community Toolkit behavior won't work on this?

P.S. I removed the TextChanged="OnTextFieldChanged" from the Entry, but that did not solve the problem.

You need to pass context to the command. Sample: https://github.com/xamarin/XamarinCommunityToolkit/blob/main/samples/XCT.Sample/Pages/Behaviors/CharactersValidationBehaviorPage.xaml#L57

@EmberLynn, is this project on GitHub? That way we can take a look at it.

I apologize, this isn't available on github. This is a company project I'm working on.

So, from your screenshot, I believe the ContentPage.BindingContext is AddEditRequestMockupViewModel. So, Behaviors don't inherit the BindingContext from its parent, you need to do it.

<ContentPage  x:Name= "this">

<Entry>
   <Entry.Behaviors>
          <t: EventToCommandBehavior Command="{Binding YourCommand, Source={x:reference this.BindingContext}}" />
   <Entry.Behaviors>
</Entry>
</ContentPage>

So, here's a snippet of the code, I think this will work for you

Thank you for your recommendation. Unfortunately, I was not able to get it to work. Here is what my code looks like after making the suggested change:

<DataTemplate x:Key="EntryFieldTemplate">
    <VerticalStackLayout Padding="5"
                         x:DataType="model:CustomFormField">
        <Label Text="{Binding Name}"/>
        <Entry Placeholder="Enter your sentence here"
               Text="{Binding TextValue}"
               BindingContextChanged="OnTextFieldChanged">
            <Entry.Behaviors>
                <toolkit:EventToCommandBehavior
                    EventName="TextChanged"
                    Command="{Binding ToggleIsSubmitButtonEnabledCommand, Source={x:Reference this.BindingContext}}"/>
            </Entry.Behaviors>
        </Entry>
    </VerticalStackLayout>
</DataTemplate>

Also, I included x:Name="this" to reference the ContentPage as you suggested.

try something like this: https://github.com/VladislavAntonyuk/MauiSamples/blob/main/MauiBank/Views/CardPage.xaml#L102

if it doesn't work please include a small repro
