Enabling Required Field Validator prob.

lucho1970 · October 21st, 2004, 10:03 AM

I have a check box on a form that, when checked, enables a bunch of fields on the form. These fields have Required Field Validators attached to them.

I have no problem enabling them and disabling them based on the check box, the problem I am having is that as soon as they are enabled, they are all validated and their messages displayed.

In other words, I don't want to see a message or any indication that they are invalid simply by enabling them. I want this to happen once they try to submit the form, or when they leave the text box without populating it.

Any Suggestions?

Luis

Are you enabling a linkbutton control at all, or another form of a button?

<%@ Page Language="VB" %>
<script runat="server">

    ' Insert page code here
    '

    Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs)
        TextBox1.enabled = not TextBox1.enabled
        TextBox2.enabled = not TextBox2.enabled
    End Sub

</script>
<html>
<head>
</head>
<body>
    <form runat="server">
        <p>
            <asp:CheckBox id="CheckBox1" runat="server" OnCheckedChanged="CheckBox1_CheckedChanged" AutoPostBack="True"></asp:CheckBox>
        </p>
        <p>

sorry this is the correct code:

<%@ Page Language="VB" %>
<script runat="server">

    ' Insert page code here
    '

    Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs)
        TextBox1.enabled = not TextBox1.enabled
        TextBox2.enabled = not TextBox2.enabled
    End Sub

</script>
<html>
<head>
</head>
<body>
    <form runat="server">
        <p>
            <asp:CheckBox id="CheckBox1" runat="server" OnCheckedChanged="CheckBox1_CheckedChanged" AutoPostBack="True"></asp:CheckBox>
        </p>
        <p>
            <asp:TextBox id="TextBox1" runat="server" Enabled="False"></asp:TextBox>
            <asp:TextBox id="TextBox2" runat="server" Enabled="False"></asp:TextBox>
        </p>
        <p>
            <asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>
        </p>
        <p>
            <asp:RequiredFieldValidator id="RequiredFieldValidator2" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox2"></asp:RequiredFieldValidator>
        </p>
        <p>
            <asp:Button id="Button1" runat="server" Text="Button"></asp:Button>
        </p>

    </form>
</body>
</html>
