Validator for RadNumericTextBox created dynamically

[iomega 55]

Hi:

I'm creating codebehind a radnumerictextbox, and I need to have mandatory a positive value between 0 and 100. I found if a set you can still leave empty the textbox and radnumeric doesnt complaint about it, also you can write the negative sign (-) and it permits you write it

- how do I need to configure in my radnumeric for complaint when I have an empty value
- how do I need to configure in my radnumeric for complaint when I write a negative sign
- how can I create a dynamic custom o request validator in the codebehind for a radnumeric textbox
- does the radnumeric have an attribute or method for defining a message when it has an error or warning


Thanks in advance.

Hello,

Try the following approach and see whether it suits your need.

- Added OnKeyPress event in order to prevent the negative sign(-) from entering into the textbox.
- Attach OnError client event for displaying the error message when it has an error or warning.
- Added RequireFieldValidator for ensuring that the textbox has value when page is submitted.

C#:

    RadNumericTextBox textbox = new RadNumericTextBox();
    textbox.ID = "textbox1";
    textbox.MinValue = 0;
    textbox.MaxValue = 100;
    textbox.ClientEvents.OnError = "OnError";
    textbox.ClientEvents.OnKeyPress = "KeyPress";
    this.form1.Controls.Add(textbox);

    RequiredFieldValidator rfv = new RequiredFieldValidator();
    rfv.ControlToValidate = "textbox1";
    rfv.ID = "RequiredFieldValidator1";
    rfv.ErrorMessage = "Textbox cannot be blank";
    this.form1.Controls.Add(rfv);

JavaScript:

<script type="text/javascript">
function KeyPress(sender, args)
{
  if(args.get_keyCode() == 45)
  {
    alert("Enter non-negative numbers only");
    args.set_cancel(true);
  }
}
function OnError(sender, args)
{
   alert(args.get_reason());
}
</script>
