calling function from gridview

[tarscher]

Hi all,

I have a label in a gridview that contains the duration of a run. I use
Text='<%# CalculateDuration(Convert.ToDateTime(Eval("StartTime")),
Convert.ToDateTime(Eval("EndTime"))) %>'>

The gridview also contains
<asp:BoundField DataField="StartTime" HeaderText="Start Time"
SortExpression="StartTime" />
<asp:BoundField DataField="EndTime" HeaderText="End Time"
SortExpression="EndTime" />

When I debug CalculateDuration(DateTime start, DateTime end) is see the
function is called but the datetime is always 01/01/0001 0:00:00. I
guess the time isn't passed correctly.

Someone knows why?

regards,
Stijn
