Question

I have a custom control that inherits from a datagrid. I have to evaluate a property each time the data is bound the grid. I am currently binding using DataSource=”{Binding….}”

Is there a way that I can create a new dependency property (?) which which will be evaluated each time the DataSource property is changed? Can I somehow “attach” my method to the DataSource Property?

I hope my intent is clear.

Thanks for any thoughts.

Answer 1

I was able to handle this by overriding OnPropertyChanged and using the following code along with my new dependencyproperty –

if(e.Property.Name = "DataSource")
{
// Invoke my new method
}
