Can't bind column to external control when grid created in code
posted

Although I have no problem binding WebDateTimeEdit control to a column when the grid was declared in the HTML, the same code throws a null exception on the .EditControlID reference when the grid was built in code. The value of the .EditControlID property is nothing at the time the exception is thrown. I'm using version 6.2. Here is a simple HTML/VB example. Am I missing something?

Thanks
