Grid not formatting nullable datetime column

[Kevin]

I am having trouble with formatting a column that is bound to a nullable datetime field. The grid is bound on the client side using ajax. Wondering if anyone has seen this behavior before, and if so, what the solution was.

Here is the part of the grid instantiation code that formats the nullable datetime field:

columns.Bound(c => c.MediaFileVersion.MediaFile.LastCheckOutDate).ClientTemplate("<#= $.telerik.formatString('{0:MM/dd/yyyy - hh:mm tt}', GetDateFrom(LastCheckOutDate)) #>").Title("Check-out Date");
                        

The LastCheckOutDate field is of type nullable datetime.

The page has a javascript error like this:

Uncaught ReferenceError: LastCheckOutDate is not defined

It seems that Telerik grid does not know how to render a nullable datetime field. Would appreciate any help or ideas relating to the above problem.

Thank you

Hello Kevin,

The GridDateTimeColumn supports nullable values and should display empty cell if the value is null. I am attaching a sample project where the RadGrid has a GridDateTimeColum with null values.

From the provided code it would be hard to determine what is the reason for the error. Could you share your markup with the code behind so we could further investigate the issue and help you find a solution?
