    Dear Sir,

    I use RadNumericUpDown control in RadGridView / GridViewDataColumn / CellEditTemplateSelector

    <DataTemplate x:Key="DtNumberKuendigungsfrist" >

               <Controls2:RadNumericUpDown Value="{Binding Path=Kuendigungsfrist, Mode=TwoWay}"

                                            IsEditable="True" Minimum="0" Maximum="9999" SmallChange="1" LargeChange="4"

                                            ValueFormat="Numeric" NumberDecimalDigits="0"/>


    Every time I press the small arrows up or down, the value in my viewmodel is changed immediately. How can I change the behavior of this control, to update the viewmodel only, when the focus in RadNumericUpDown is lost?

    Best Regards

    Hello Thomas,

    I'm afraid that this behavior of RadNumericUpDown cannot be modified - the ViewModel is updated as soon as the value is changed.
