How to check dates

Question

How to check date should not be greater than today date using compare field validator i:e Client side validation in asp .net

I have used this

<asp:comparevalidator ID="Comparevalidator2" runat="server" errormessage="The date must be greater than today"

controltovalidate="txtRegDate" type="Date" Operator="GreaterThan"

valuetocompare='<%= DateTime.Now.ToShortDateString() %>' />

Getting Error

The value '<%= DateTime.Now.ToShortDateString() %>' of the ValueToCompare property of 'Comparevalidator2' cannot be converted to type 'Date'.

Try like that: asp:CompareValidator ID = Comparevalidator2 runat = server ErrorMessage = The date must be greater than today ControlToValidate = txtRegDate Type = Date Operator = GreaterThan ValueToCompare =   /> Add below code in your code-behind page: protected void Page_Load( object sender EventArgs e) { Page.DataBind(); }
