Wow, that's looking really great. I especially like the possibilities of the TextFormatString property!

Any examples in text i.e. not Video?

I am having  an error while trying to use the combo box inside a DetailsView control when the multi column feature is enabled. Setting the combo's property: Value='<%# Eval("SomeID") %>' seem to trigger the error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

The error goes away if i set DetailsView EnableViewState="False" or remove the multiple columns. Is this a bug?

Hi Mehul,

Thanks for making the video. I've implemented a multi column combo box column in a gridview. It works great, except I am not able to change the display format for columns in the combo box, especially when data types are

  boolean --- showed as True/False while users want Yes/No

  small money  -- scale showed four digits instead of two, e.g. 25.0000 instead of 25.00

The gridview is Is there any way to control the format in this version or in a newer version?
