[hazardvn]

<ext:DateField ID="dfFrom" runat="server" Width="100" FieldLabel="From" Format="MM/yyyy"
                AllowBlank="false" />

If today is last month and days of month = 31 days. When I chose other month,which has days smaller than 30 then it automatically jump to other months. Can you have a solution for this error.
