Why does emptymessage property do auto validation?

Question

I am using Radnumericbox like that,

 <telerik:RadNumericTextBox CssClass="app-input" ID="txtUnivaPerfTreshold" runat="server" MaxValue="100" MinValue="1" MaxLength="4" Value="30" EmptyMessage="between %1 - %100" Width="130px" Type="Percent">

When I add EmptyMessage property to radnumerictextbox , on page submit textbox do auto validation. And red border appears out of textbox. If I dont add empty massage property to radnumerictextbox on page submit textbox is not do autovalidation. I want to use Empty message property but I dont want any validation and red border.

how can I do that?

Answer 1

I find the solution. If you are EmptyMessage and MaxLenght property in same item, telerik use autovalidation it's own. If you delete one of EmptyMessage or MaxLenght propery in item, autovalidation does'nt work. There is no way for use EmptyMessage and MaxLenght in same item without autovalidation.

Answer 2

I tried this

    <telerik:RadNumericTextBox CssClass="app-input" ID="txtUnivaPerfTreshold" runat="server"
                               MaxValue="100" MinValue="1" MaxLength="4" Value="30" EmptyMessage="between %1 - %100" Width="130px" Type="Percent">
    </telerik:RadNumericTextBox>
    <asp:Button ID="Button1" Text="submit" runat="server" />

and

protected void Page_Load(object sender, EventArgs e)
{
    System.Threading.Thread.Sleep(3000);
}

to make sure I see any such styling, but none was added. Take a look at the surrounding code to see if anything else is affecting the control (custom validators, validation being set in the code-behind, etc.).

Finally, examine the rendered HTML to override the CSS you do not like. I think riError is the class the input will get when invalid, so you can remove borders and any other styling you don't want.
