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

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="<%# DateTime.Now.ToShortDateString() %>" />
Add below code in your code-behind page:
protected void Page_Load(object sender, EventArgs e)
{
   Page.DataBind();
}

Operator="GreaterThan" type="String" ControltoValidate="EndDateTextBox"
 ErrorMessage="The 'End Date' must be after today" 
runat="server" />

.NET:

(In Page_Load method)

CompareEndTodayValidator.ValueToCompare = DateTime.Now.ToShortDateString();
