Misunderstanding or problem w/ DataBinding collection

I've got a form with a number of different controls (UltraTextBox for instance) that are bound to a data source. There's also a grid bound to the same datasource.

As I change values in the controls, I'm using the following code to update the datasource and display in the grid the values that were entered into the controls.

IF VALID-OBJECT(curControl:DataBindings) THEN curControl:DataBindings:WriteValue().

Included on the form are UltraCheckBoxes. These controls are bound using CheckedValue rather than Value. Now, in my code I have to test for a DataBinding type of CheckedValue as well as Value.

I'd like to just test for the first DataBinding item for the control (System.Windows.Forms.Control) using:

IF VALID-OBJECT(curControl:DataBindings[0]) THEN curControl:DataBindings[0]:WriteValue().

but this throws a syntax error stating that the "The specified indexer type does not match any type required by this object. (13811)".

In the class browser, the DataBindings collection shows both a character and integer property for retrieving the System.Windows.Forms.Binding from the collection object:

PUBLIC PROPERTY Item AS System.Windows.Forms.Binding

PUBLIC PROPERTY Item AS System.Windows.Forms.Binding

Is there something I'm not doing correctly with regard to the integer property that's causing it to not work?

Thanks,
