I am using the DevExpress aspxgridview in work.The documentation says you need to specify a key field name but I cant find a reason beyond, because we said so. Does anyone know what this is for? Do I only need one, or one for each field?

I have an aspxgridview which groups first by year and then by month. Basically my query returns Month and year as seperate columns. Now if I return month as "January or February" then ASPxGridview does not know how to sort this.
I heard of custom sorting, but even then if I return month column as a number and use dataitem template to convert it to a name...it works but then when exporting it only exports the number not the dataitemtemplate.
I am trying to display an error message in the edit section of a ASPxGridView when a user has tried to submit invalid data.I have been looking around and have found one blog that allows me to place an error message in red once it has filed validation by throwing a New InvalidOperationException.
I am using the rowUpdating method as described in the blog, but the exception forces my code to stop the code in visual studio (like you would at a break point) and displays the message. Once I click play again, the code carries on and the program continues. How do I stop the application from stopping once the exception has been called and carry on.

Any resolution to make the cascading dropdowns work as expected when used inside edit mode of AspxGridview. I am using DevExpress Controls.
My requirement is as follow:
If I select country="United States" then populate the "State" combobox and on selection of "State" populate the "City" combobox.
If I select "country" other then "United States" then populate only "City" combobox with cities of selected "country" and no need to populate the "State" combobox. Also I need to hide the "State" combobox. i.e. like
Country State City
ROW1 united states Alaska Douglas
ROW2 Canada Toronto
ROW3 Australia Sydeny
ROW4 united states California Yuba City
Same is required in Editmode also.
I'm trying to change the value in an editform before it becomes visible to the user. However the aspxgridview is always overwriting this.
This is my solution:

If (e.RowType = GridViewRowType.EditForm) Then
