User input date Validating

[Tamer Ibrahim]

Hi,

I'm trying to validate user input date using range validator on a text box .
This code is throwing this exception

"The value 'DateTime.Now;' of the MaximumValue property of 'rvQDate' cannot
be converted to type 'Date'. "

<asp:TextBox ID="txtQDate" runat="server" Enabled="False" ></asp:TextBox>

<asp:Image ID="iQDate" runat="server" ImageUrl="~/images/Calendar.png"
Visible="False" />

<cc1:CalendarEx tender ID="calQDate" runat="server" BehaviorID="cal QDate"
TargetControlID ="txtQDate" PopupButtonID=" iQDate" Format="dd/MM/yyyy">

</cc1:CalendarExt ender>

<asp:RangeValid ator ID="rvQDate" runat="server" ControlToValida te="txtQDate"
Display="Dynami c"

ErrorMessage="I nvalid QDate." MaximumValue="D ateTime.Now;" Type="Date"
CultureInvarian tValues="True"> *</asp:RangeValida tor>

How can I solve this ?

You can not set the MaximumValue="D ateTime.Now" like that (declaratively) .
This will cause the value to be set to the literal string value, which
throws an error.

You can set it programmaticall y, though.
Leave the MaximumValue empty, and add this line to the Page_Load event:
rvQDate.Maximum Value=DateTime. Now
