why my compare validator control post back when EnableClientScript="true".

<asp:CompareValidator ID="CompareValidator1" runat="server" EnableClientScript="true"
                       ControlToCompare="txthdnREsult" ControlToValidate="txtCaptcha"
                       ErrorMessage="Invalid Captcha Entered."></asp:CompareValidator>

after click on submit button it goes to button click event handler why it is not compare at client side

 Protected Sub btnCheck_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnCheck.Click
        Label1.Text = ""
        Page.Validate()
        If Not Page.IsValid Then
            Return
        End If
End Sub

Solution 1

two or three things are missing in your code that you may try.

add validation group on button and validation control
add operator & type property for the compare Validator.

it will define that what datatype you want to compare and what case do you want to compare.

ASP.NET

<asp:comparevalidator id="CompareValidator1" runat="server" enableclientscript="true" xmlns:asp="#unknown">
                       ControlToCompare="txthdnREsult" ControlToValidate="txtCaptcha"
                       ErrorMessage="Invalid Captcha Entered." Operator="Equal" Type="String" ValidationGroup="groupname"></asp:comparevalidator>
