How can I access a DataSource object in code behind

Question

I specify the object for my DataSource in XAML like this.

<Grid.Resources>

  <c:SpectralDeviceFilterBinding x:Key="DataSource"/>

</Grid.Resources>

I would like to access that object (SpectralDeviceFilterBinding) from code behind, but can't determine how to name or otherwise reference the instance that the page creates when it loads.

How To?

Thanks

 

 

 

 

Answer 1

Did you try FindResource("DataSource")?

Answer 2

That throws an exception

System.Windows.ResourceReferenceKeyNotFoundException was unhandled by user code
  Message="'DataSource' resource not found."

This works

  TheGrid.TryFindResource("DataSource");

 

 

 

Answer 3

Any thoughts/explanation on FindResource not working?

Answer 4

FindResource looks into the current object resources (Window/Page) and then Application's resources etc. It will not find anything because the resource is defined in the Grid - and this is why TheGrid.FindResource works.

You should check the documentation to see how the resource lookup works:

Answer 5

I was simply following the suggestion in the initial reply to my question, which did get me to the right answer at least.

Thanks for the info and doc link.
