When MinValue RadNumericTextBox postback even if no change

[CSurieux]

Hello,

I discovered that my radNumericTextBoxs postback when user try to decrease the value under the minimum, even if the result is no change in value.
How could we avoid this, it should not postback if no change occurs in the displayed value, it has great network cost on my app.

Is this a bug, should I open a ticket

Thanks for help.

Hello Christian,

You are correct that the RadNumericTextBox postbacks when AutoPostBack="true" and the user enters a value that is out of the valid range. However you can change this behavior using both OnValueChanging or OnValueChanged events with the following code as an event handler:

function ValueChanged(sender, args)
            {
                if (args.get_newValue() < sender.get_minValue())
                {
                    args.set_cancel(true);
                }
            }

You can learn more about those events in the following help topics:

OnValueChanging

OnValueChanged

I hope this helps.

Hello Martin,

Thanks for answer, the default behavior should be to not post when nothing change, and we should not be obliged to add again 2 lines of javascript: my pages are full of theses javascript corrections.
May I request a change for this.

Anyway thanks

Hello Christian,

To avoid using the Javascript approach as per my last post please log into your account and download the latest internal build of the controls or just click here. Then set AllowOutOfRangeAutoCorrect="false" of the RadNumericTextBox control. This setting will prevent the the unwanted postback when invalid value is entered.

I hope this helps.
