[Solved] How to swith IsRequired off ?

[juststarting]

Hi,

I have 3 fields on a webpage. I need to make sure that at least 2 of the 3 being completed (any combination). So I added a RadInputManager and added the TargetInput Controls for all 3. This require the client to complete all 3. Is there a way to do this that only 2 of the 3 needs to be completed?

Thanx in advance for all help.

Hello,

Try the followong approach by using CustomValidator control in order to validate the textboxes.

ASPX:

    <telerik:RadTextBox ID="RadTextBox1" runat="server">
    </telerik:RadTextBox><br />
    <telerik:RadTextBox ID="RadTextBox2" runat="server">
    </telerik:RadTextBox><br />
    <telerik:RadTextBox ID="RadTextBox3" runat="server">
    </telerik:RadTextBox><br />
    <asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="validate"
        ErrorMessage="CustomValidator"></asp:CustomValidator>
    <asp:Button ID="Button1" runat="server" Text="Button" />

JavaScript:

<script type="text/javascript">
function validate(sender, arg)
{
    var textbox1 = $find("<%= RadTextBox1.ClientID %>");
    var textbox2 = $find("<%= RadTextBox2.ClientID %>");
    var textbox3 = $find("<%= RadTextBox3.ClientID %>");
    var value1 = textbox1.get_value();
    var value2 = textbox2.get_value();
    var value3 = textbox3.get_value();
    if((value1=="" && value2=="")||(value1=="" && value3=="")||(value2=="" && value3==""))
    {
        arg.IsValid = false;
    }
}
</script>
