Hi,

I want to compare two dates (two textboxes) using compare validator.
I use the code:

XML

<asp:comparevalidator id="valCmpDate" runat="server" controltocompare="txtExpiryDate" controltovalidate="txtDateOfIssue" ErrorMessage='Please enter a date lessthan exipry date' Operator='LessThan' Type='Date' />

But it checks only the date portion, not month and year.
For example:
If txtExpiryDate=2010-06-23 and txtDateOfIssue=2009-06-25

I got the result txtDateOfIssue is greaterthan txtExpiryDate

Please Help

Thanks in advance.... :)

hi u can use custom validator instead of compare validator.

XML

<div>
       expiry date: <asp:TextBox ID="TextBox1" runat="server" ></asp:TextBox>
        issue Date :<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:CustomValidator ID="cus" runat="server" ErrorMessage="Please enter a date lessthan exipry date" OnServerValidate="validateExpiryDate" ></asp:CustomValidator>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
    </div>

the date format should be : mm/dd/yyyy or mm-dd-yyyy
ex. 06/25/2010 or 06-25-2010

the code behind is :

protected void Button1_Click(object sender, EventArgs e)
{

}
protected void validateExpiryDate(object source, ServerValidateEventArgs args)
{
DateTime issuedate;
DateTime expirydate;
DateTime.TryParseExact(TextBox1.Text.Trim(), new string[] { "MM/dd/yyyy", "MM-dd-yyyy" }, null, System.Globalization.DateTimeStyles.AllowWhiteSpaces, out expirydate);
DateTime.TryParseExact(TextBox2.Text.Trim(), new string[] { "MM/dd/yyyy", "MM-dd-yyyy" }, null, System.Globalization.DateTimeStyles.AllowWhiteSpaces, out issuedate);
args.IsValid = issuedate < expirydate;
}
