In My Application server side validation function is not working.even function is not called. i have put debugger on thuat function but it is not stopped ny debugger .ie function is not called

<asp:TextBox type="text" ID="txtMobilePhone" runat="server" ClientIDMode="Static" CausesValidation="true"/>
                        <asp:CustomValidator ID="cvMobilePhone" runat="server" OnServerValidate="cvMobilePhone_ServerValidate" 
                            Text="Mobile Phone already exist in this Reward Program." ErrorMessage="Mobile Phone already exist in this Reward Program."
                            Display="Dynamic" ValidationGroup="vgStep2" ControlToValidate="txtMobilePhone" CssClass="error"></asp:CustomValidator>
                        <asp:RequiredFieldValidator ID="rfvMobilePhone" runat="server" ControlToValidate="txtMobilePhone"
                            ErrorMessage="Mobile Phone is required." CssClass="error" ValidationGroup="vgStep2"></asp:RequiredFieldValidator>
                        <asp:CustomValidator ID="cvMobilePerVal" runat="server" ClientValidationFunction="validateEmailOrMobilePerVal"
                            Display="Dynamic" ValidationGroup="vgStep2"></asp:CustomValidator>


 <asp:Button ID="btnStep2Upper" runat="server" ClientIDMode="Static" OnClick="btnSaveContactClick" Text="Save" ValidationGroup="vgStep2" vg="vgStep2" OnClientClick="return ClientValidate();" />

Server Side Code

    protected void cvMobilePhone_ServerValidate(object source, ServerValidateEventArgs value)
        {  /* I have put debugger here but control is not coming here*/
            /* my validation logic*/
protected void cvMobilePhone_ServerValidate(object source, ServerValidateEventArgs value)
    {
        if (txtMobilePhone.Text.Trim() != "")
        {
            RewardProgramDataContext db = new RewardProgramDataContext();
            Boolean f = false;
            string MobilePhone = cmnFunc.RemoveMobilePhoneFormat(txtMobilePhone.Text.Trim());
            if (Request["id"] != null)
            {
                var cData = db.spContactSelectAllSingle(new Guid(Request["id"])).SingleOrDefault();
                if (cData != null)
                {
                    if (cmnFunc.RemoveMobilePhoneFormat(cData.MobilePhone) == MobilePhone)
                    {
                        f = true;
                        value.IsValid = true;
                    }
                }
            }
            if (f == false)
            {
                var res = db.spContactDuplicateMobile(new Guid(ddlContactList.SelectedValue), MobilePhone).SingleOrDefault();
                if (res.Column1 <= 0)
                {
                    value.IsValid = true;
                    customIsValid = true;
                }
                else
                {
                    value.IsValid = false;
                    customIsValid = false;
                }
            }
        }
    }

Answer 1

You forget to set the ControlToValidate property?

<asp:CustomValidator ID="cvMobilePhone" runat="server" ControlToValidate="txtMobilePhone" OnServerValidate="cvMobilePhone_ServerValidate" 
                            Text="Mobile Phone already exist in this Reward Program." ErrorMessage="Mobile Phone already exist in this Reward Program."
                            Display="Dynamic" ValidationGroup="vgStep2" CssClass="error"></asp:CustomValidator>

Answer 2

You have a combination of two different things causing this behaviour.

Firstly, note that although—as has been said by others—you do not have to specify ControlToValidate , doing so restricts the circumstances in which the server-side custom validation event will fire. Specifically, if you leave it unset, the event always fires on postback, whereas if you set it, the event only fires when the control identified by ControlToValidate has a non-empty value .

Secondly, by specifying OnClientClick, you are telling the framework that you will take care of client-side validation, which will now not fire unless you call it from your OnClientClick function. Although you have not included your ClientValidate function in your question, I suspect you are not doing so, which leaves your RequiredFieldValidator powerless to prevent the postback.

In combination, these two things mean that

• the postback occurs despite the empty textbox, and
• the server-side custom validation does not fire on postback, because of the empty textbox.

You can call the client validation from your custom function using Page_ClientValidate()) , which will be present in your page script since the page contains validators.

function ClientValidate() {
    if (Page_ClientValidate()) {
        //do custom validation, maybe return false 
        return true;
    }
    else {
        return false;
    }

}
