Is it possible to call a server side method in a client side comparevalidator in ASP.

Hi All,

I have the following validator in my project which validates the dates entered in two fields like so:

<asp:CompareValidator ID="CompareValidator10" runat="server"  ValidationGroup="dateDaysGroup" ControlToValidate="EndDate" ControlToCompare="StartDate" Type="Date" Operator="GreaterThan" ErrorMessage="End Date must be after Start Date." Display="Dynamic"></asp:CompareValidator>

is there a way i can call a method from the server side to only trigger the validator above if the start and end date are different? i.e

could i do something like this:

public void CheckDates()
{
  if(startDate != endDate)
{
  //trigger validator (basically make it active)
}

}

is there a way i could call the CheckDates() in the CompareValidator in the client side? is this even possible?

What I have tried:

I'm not really if this is possible but i have tried to research on googl.com
