    Ext.Net.DateColumn Format issue

    Danil posted that the Format property of the DateColumn should use the .NET date format located here:

    However, I found that using lower case m "m" or "mm" uses the month instead of the minute as specified in the .NET specification. Using "n" or "nn" does work however...just thought i'd document that as a bug to help anyone that might run into the same problem.

    "mm" appears to be working fine for me.

    But, really, there is a problem with "m". According to .NET specifiers "m" is "the minute, from 0 through 59."

    However, there is no such format in ExtJS (PHP), there is only the minute with leading zeros, i.e. from 00 to 59.

    Therefore the Format="m" is just not converted and stayed "m" on client side, which means the month with leading zeros.

                    new object[] { DateTime.Now },
                    new object[] { DateTime.Now.AddMinutes(1) },
                    new object[] { DateTime.Now.AddMinutes(2) }

                        <ext:DateColumn Header="Minutes" DataIndex="test" Format="mm" />

    Please clarify do you mean .NET specifiers here or ExtJS (PHP)?
    Using "n" or "nn" does work however

    OOPS - My Mistake - you are right!

    I must have been getting confused with the PHP vs. .NET - i knew that "m" wasn't working, and i thought i tried "n" and it worked, but i must have been looking at something be clear "mm" is the ONLY format you can use for minutes. i.e.:

         Ext.Net.DateColumn c = new Ext.Net.DateColumn();
         c.Format = "M/d/yyyy h:mm A";
    "n" and "nn" are the PHP codes for month i.e.:

         rdr.Fields.Add(colName, Ext.Net.RecordFieldType.Date, "n/j/Y g:i:s A");
    Sorry Danil!
