NumericUpDown SelectAllOnFocus doesn't work

[fredericoregateiro]

What steps will reproduce this issue?

Setting the SelectAllOnFocus="True" property on a NumericUpDown control has no efect, on other and using the Controls:TextBoxHelper.SelectAllOnFocus="True" work as expected, selecting all text.

Expected outcome

Setting the SelectAllOnFocus="True" on a NumericUpDown control should have the same behavior like the Controls:TextBoxHelper.SelectAllOnFocus="True"

Environment

• MahApps.Metro v1.2.4
• Windows 10
• Visual Studio 2013
• .NET Framework 4.5

@punker76 I saw that you introduced the SelectAllOnFocus property in NumericUpDown. Wouldn't it be better to remove it, because no other control (also .NET internal controls) has such a property and completely rely on TextBoxHelper.SelectAllOnFocus

@xxMUROxx I'll look on this

Hi,
I cannot enable the "select all on focus" for NumericUpDown control, it won't work neither with latest release 1.3 nor 1.4.0-ALPHA026�
<NumericUpDown metro:TextBoxHelper.SelectAllOnFocus="True" SelectAllOnFocus="True"�/>
Do you have any ideas?
Thanks,
collegedude

@collegedude You need only metro:TextBoxHelper.SelectAllOnFocus="True" the other one is obsolete. It works at the main demo.

<Controls:NumericUpDown Controls:TextBoxHelper.SelectAllOnFocus="True"
                        ButtonsAlignment="Left"
                        Interval="5"
                        Value="500" />

Hi again,
Thank you! The demo application is in fact working, but not my own application (also with MetroWindow). I will try to reproduce the problem with the demo application...
I have added both, the obsolete property and the TextBoxHelper, just to show that they are both not working.

Hello everyone,

i want to say thanks for your effort for this amazing work.
Like @collegedude say, the attached property Controls:TextBoxHelper.SelectAllOnFocus is working fine on the application demo, but i cannot use it in my own applications.

Also, the control won't take focus even if i simply click on it, but just when you click the contained value.

Hello @Cicciomnz,
In my case it works if I add the following line in every UserControl that makes use of the TextBoxHelper:

    <UserControl.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </UserControl.Resources>
�

In my case it was not enough to have this line in App.xaml or MainWindow.xaml

[Cicciomnz]

It works! Thanks a lot @collegedude

@Cicciomnz @collegedude It should also work if this resource is added in App.xaml

Also, the control won't take focus even if i simply click on it, but just when you click the contained value.

That's the behavior of all TextBoxHelper stuff like clear button or search button on TextBoxes.
