Accessing the selected content from the C# code

Hi

We are using CK editor 3.x trail version to explore the features available. We are facing issues in accessing the selected content from the C# code. The property value was returning as null whenever we are trying to access the content selected on the editor from c# code for further manipulation.

Could anyone suggest a way to access the selected content from the C# code?

Thanks in advance.
