Hi, (Sorry for the double post)<BR>I&#039;m reading the article:<BR>http://aspnet.4guysfromrolla.com/articles/072603-1.aspx<BR>to include subheaders in the datagrid.<BR><BR>I have two columns: C1 a date column with DataFormatString="{0:T}" and C2 an integer column. I want to use subheaders in order to group the times in C1 by date. So in the subheader row I want to display Thu, Nov 25 2004. However the DataFormatString property of C1 kicks in and instead of "Thu, Nov 25 2004" I get "12:00:00"<BR>Can the DataFormatString be set conditionally? Is there a workaround?<BR>Thanks.
