Hi Edward,
Thank you for the question.
Currently, RadGridView does not offer the described grouping customization built-in. Nevertheless, you could implement such scenario. For example, you could add one calculated column which takes one of the needed values (today, yesterday, last week etc.) according to the some data field and then apply grouping on this column.
If you have other questions, do not hesitate to contact me again.

In such a case, how can grouping be configured ot use a different field? For example... I display a regular date in the grid (10/12/2007, etc.), but when the user groups by that field, I want to use a hidden field that contains a string like "Today, Yesterday, etc." How can a group by expression be configured to use a custom field other than the one that was dragged and dropped? Otherwise I don't see a way to do what you are describing without eliminating the standard formatted date altogether.

Hi Levi,
Thank you for writing.
RadGridView does not support the described scenario. You cannot drag a column in the grouping area and apply grouping criteria based on another field. Nevertheless, you could add a column with expressions depending on DateTime column. After that apply grouping on this column. Please, find attached example project that demonstrates this approach.
Contact me again if you have other questions.

I keep receiving an error opening this project.
(Cannot create an instance of the abstract class or interface 'Telerik.WinControls.UI.GridViewDataColumn)
Do you have a version of this that would work with VS2010? I believe this project may answer my question

Hello,
you cannot create an instance of this. You will need to create an instance of a specific type such as GridViewTextBoxColumn or GridViewDecimalColumn for exmaple.
Hope that helps but let me know if you need more information.
