Hi Yanko Nikolov ,

Thanks for your reply.

I am using unbound field and in the field settings i am using edit as type as  shown below

EditAsType="{x:Type sys:Int16}"

I have also noticed this issue in WPF netadvantage feature browser under xamdatgrid->Data Binding and Interactions-> Unbound Fields, check any filed like Price,Quality etc.

Thanks in advance
 

Hello Manuj,

Hello Manuj,

Thank you for your reply. I assume that you would like not to change the value with the up arrow key when it is null in the unbound field. If it is true, I can suggest you define a style for the XamNumericEditor and define a EcentSetter for the ‘PreviewKeyDown’ event like :

  <Style  TargetType="{x:Type igEditors:XamNumericEditor}">

            <EventSetter Event="PreviewKeyDown" Handler="KeyDownEvent"/>

        </Style>

…

void KeyDownEvent(object sender, KeyEventArgs e)

        {

            if ((sender as XamNumericEditor).DisplayText == "" && e.Key== Key.Up)

            {

                e.Handled = true;

            }

        }

This way when the value is empty and press the ‘Up’ arrow, the value won’t become – 9999999.

If you need any further assistance on this matter, feel free to ask.
