Using RADNumericUpDown

[Ivan]

Hello everybody!
My radnumericcontrols have a strange behaviour . For example : if i insert the value 20, when the control lost focus, the value is set to 200%, wich isn't the correct value, at least the value I want. There is another issue here . What is the default decimal separator ?If I try to use the normal "comma", nothing happens . If I insert the value "10,23", the control doesn't accept my comma , so, instead of having the value "10.23", I get the value 1023 .

Any suggestions ?

Hi Ivan,

About your first question - this is actually the intended behavior of the control. We tried to replicate the Excel's behavior. If you open Microsoft Excel and set formation of a cell to be percentage you will see that it behaves exactly the same way - if you enter 3, the value will become 300%. This is because some programs need this behavior and use it.

To accomplish the behavior you desire you can use the NumericUnit property and set it to "%" .  The default separator is not a comma but dot. If you want to change it you can use this line of code:

numeric.NumberFormatInfo.NumberDecimalSeparator = "," ;

This will overwrite only the visual look, however, you will still have to use numpad's dot to put the separator.

With all of my respect, but why I can use only numpad decimal separator ? why I cannot use , or . keys on the keyboard ? - most of our users are using notebooks and difficult to press numpad decimal separator.

Hello Dogu,

The problem with the decimal point comes from the Silverlight framework itself. In case you are using a laptop and press the decimal point key you will get an Unknown key as an argument in the KeyDown event handler. We have find a workaround to this problem using the virtual-key codes table. Unfortunately, we have resolved the problem in case your operating system is Windows, because the virtual-key codes depends on the operating system itself. If you are using MAC OC X, you should wait a little bit to get the things in the right way. In case you need that functionality really urgent, we can provide you with an internal built that will resolve the problem until our official release is out later this month.

Hello Ercument Berktas,

That is quite strange because I have tested the problem using my Dell vostro 1500. Moreover, if I go to the Silverlight demo website and I try to input decimal point using the laptop keyboard it doesn't seem to have any problems with it. What I can ask you is to create a simple textbox and wire up to the KeyDown event, and check the PlatformKeyCode of the KeyEventArgs. What you should get is PlatformKeyCode = 0xBE or 190 in integer. As its specified in the Virtual-Key codes by Microsoft this is the keycode of the decimal point in any Windows operating system here. If your keyboard returns different PlatformKeyCode then the one I mentioned, you are having some troubles with the layout of your keyboard. Get back to me as soon as possible so we can investigate this problem further, in case you are having really though time making it work, you can write me at hristo.borisov at telerik.com, so we can fix it, and post the solution here so everybody can access it.

con esto corrigen el problemas de los decimales.

COORDENADAS_X.NumberFormatInfo.NumberDecimalDigits = 6;

COORDENADAS_X=es el nombre del control
NumberFormatInfo=referencia a la cultura
NumberDecimalDigits=para que acepte los numero decimales
6= la cantidad de decimales que quieres que aceptes

Hello Boyan,

I want to know if is it possible to do that RadNumericUpDown accepts dot AND comma ?

I see this code on the web :

if (e.KeyChar.Equals('.') || e.KeyChar.Equals(','))
{
    e.KeyChar = ((System.Globalization.CultureInfo)System.Globalization.CultureInfo.CurrentCulture).NumberFormat.NumberDecimalSeparator.ToCharArray()[0];
}

 

With this code, i did it :

private void tbOpeSurValeur_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key.Equals('.') || e.Key.Equals(','))
    {
        e.Key = (Key)((System.Globalization.CultureInfo)System.Globalization.CultureInfo.CurrentCulture).NumberFormat.NumberDecimalSeparator.ToCharArray()[0];
    }
}

But :

- I havn't got '.KeyChar' => I put 'Key'

- 'e.Key' is in ReadOnly, i can't change his value..

 

Can you help me ?

Thank you.

 

Valentin.
