WPF Binding To Object Not Working

=?Utf-8?B?UGhpbCBKb2huc29u?=

Hello,

My first attempt to bind a 'detail' form to the properties on an object and
the binding is not working.

I have the following grid:

<Grid x:Name="MainGri d">
<StackPanel FlowDirection=" LeftToRight">
<TextBlock Foreground="#FF FFFFFF">First name:</TextBlock>
<TextBox Text="{Binding Path=UserName}" ></TextBox>
</StackPanel>
</Grid>

And the code behind on the load for the form runs the following... its
definitely executing and the UserName property of _user is set to "Phillip",
but nothing displays in the text box detailed above!

this.MainGrid.D ataContext = _user;

Is there some obvious properties or calls I need to set or make to get a
simple binding app like this to work? Or am I missing something else?

Thanks.

I'm no expert on this, but I think you need to specify the object that
has the UserName property in your Binding regardless of the
DataContext. Also, is UserName a DependencyPrope rty? You should
probably invest in some WPF books to get you started.

Thanks for the response...

I've read a bit about it in Essential Windows Presentation Foundation by
Chris Anderson and I'm also looking at this tutorial....

http://coredotnet.blogspot.com/2006/...-tutorial.html

The only thing different in my code is my object does not currently
implement the INotifyProperty Changed interface, but in Chris Anderson's book
he says that's optional.

Might try implementing the interface and seeing if it binds... not too
hopeful though. If anybody has any ideas I would be grateful.

Data Binding to a object...

by: Simon Verona | last post by:

I'm not sure if I'm going down the correct route... I have a class which exposes a number of properties of an object (in this case the object represents a customer). Can I then use this object to databind to text boxes etc? I can't use a dataset as the object has loads of derived logic, for example updating one property may actually update several database fields for example.

Data binding with enums?

by: David Veeneman | last post by:

I want to data bind a user control and a business object, using a BindingSource control. The control has a 'Priority' property that takes a 'Priority' enum (High, Normal, Low). The business object has a property with the same name, which takes an identical enum. Data binding isn't working, and I think it's because the two enums are different. Even though they have the same name and the same elements, they are declared under different...

Binding behaviour regarding exceptions

Is there any way to enable exception throws in VS 2005, that occur during binding operations? I am upset that i can't see exceptions that are thrown during binding operations. It's very hard to track down erroneous behaviour of your app if you can't see where the problem is... i mean it's realy hard to debug binding issues and it would be realy of help if i could somehow enable this during debug session.

Data Binding Question

by: =?Utf-8?B?VGVycnk=?= | last post by:

Think it is great the way that you can set up a datsource, value member, and display member for a combobox, and map a 'code' to a 'description' and back again by binding the combobox to a datasource that contains the code. Now suppose that you want it to be read-only? That is, you have the 'code' in your DB, want the associated 'description' to display, but not let the user change it on this particular form. There is no read-only...

This form is 'tied' together with a search form, and the user can go back and forth. When the user hits ok, the form is hidden and the search form is shown and visa-versa. The problem is that when the form is hidden when the labels visible property is False, and then...
