Property not found in type

Question

0.00/5 (No votes)

See more:

<TextBox binding="{Binding FirstName}" canvas.left="93" canvas.top="8" height="23" x:name="_arFirstName" width="120" isreadonly="True" xmlns:x="#unknown" />

The above is a piece of XAML code to which I added Binding to a Property which exists only in my domain object. Incidentally where it says Textbox "Binding" and getting an error that says: The property Binding was not found in type 'TextBox'. What am I missing to get this to refer to my domain object property in my C# code?

Thanks.

*Note* Not all of my snippet was transferred property. The first part does indicate that it is a TextBox

I've fixed the formatting so your code snippet shows in its totality :-)

Solution 1

In your Window's constructor or Load event, you need to set the data-context to your business-object.

C#

this.DataContext = yourBusinessObject;

And it's assumed that yourBusinessObject will have the FirstName property in it.

Okay. So my class is Agent. It has a property in it called "FirstName". On formload then I need a declaration like this: this.DataContext = Agent; Right?

You need an instance of Agent there. Something like

this.DataContext = new Agent(...);

or

this.DataContext = someOtherInstance.GetAgent(...);

Since my UI is in XAML/WPF, how do I instantiate a new Form Load method to insert this.DataContext?

Put it in the constructor, after the call to InitializeComponent().
