Question

I have a Silverlight application which is a collection of form fields and buttons.

I’ve created a method stub that handles a click event in the xaml.cs. When I inspect sender during debug, I can see the base type is a TextBlock, and in the DataContext object within that textblock I see my custom type’s properties. One of them is GUID – this is the Sender’s type, so I cast to a TextBlock and I can see the DataContext, but I am not sure how to get my type’s field value out of this object:

private void someTextField_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {

        var dataContext = (TextBlock) sender;
        var assetGUID = dataContext.DataContext.  /
        // intellsense does not show any fields, indexers, or getters - Just says "Get or Set datacontext fields in a datacontext".

    }

As stated, if I debug and place a watch on Sender, go two levels deep I can see my objects fields.

Thanks.

Answer 1

if you can see in Debug mode, that the DataContext of the TextBlock is your needed Object, then you just have to cast it to your object.

private void someTextField_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {

        var dataContext = (TextBlock) sender;
        var assetGUID = ((YourObject)dataContext.DataContext).getGuid()  /
        // intellsense does not show any fields, indexers, or getters - Just says "Get or Set datacontext fields in a datacontext".

    }

You need to do this, because DataContext is defined with the return value Object (DataContext)

Is this what you need?
