Rangevalidator date problem.

Last Modified: 2013-11-27
I asked this question before about checking the date with a range validator.  I need the maximum value to be set to yesterday's day in my form!  It seems to be setting the date correctly, but I do NOT get the range validator text warning msg when I enter today's date or a future date.  Please help me.

This seems to be happening at when the month changes.  If I set the date in my code -2 days which would be 9/30/2007, but then type in 10/01/2007 in the textbox, the warning msg does not appear.  I tried setting the type in the range validator to date, but I get a string error.  Please help.

        RangeValidator1.MaximumValue = DateTime.Now.AddDays(-2).ToShortDateString();

Watch Question


you need to set RangeValidator's minimum value too:
public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
        RangeValidator1.MaximumValue = DateTime.Now.AddDays(-2).ToShortDateString();    


also set validator type to "Date"

        <asp:TextBox ID="txtToDate" runat="server">10/01/2007</asp:TextBox>
        <asp:RangeValidator ID="RangeValidator1" runat="server" Type="Date" ControlToValidate="txtToDate"

<asp:TextBox ID="txtToDate" runat="server"></asp:TextBox><br />
<asp:RangeValidator ID="RangeValidator1" runat="server" ErrorMessage="Error!!!!!!" Type="Date" ControlToValidate="txtToDate" MaximumValue="2010-10-01" MinimumValue="1000-01-01"></asp:RangeValidator></div>

Thanks, but I figured it out.  I set the date and set the minimum to a crazy early date and set the maximum to yesterday's date using the datetime function.  It works fine.  I will award you the points.
