Hello

When setting the IsEnabled property of a RedNumericUpDown control to false, there is almost no visual change. Only the control does not change its border any more when hovering over it. But there is no gray background or anything like that.
When we experienced that, we tried to do it using a trigger and setting the Background property but the Background property does not seem to work.

Is there any simple solution to that apart from putting a whole new ControlTemplate?

Best regards

Christian

Hi Hristo

Thank you for your feedback. We have tested the Background property of the Q2 Version now and it's working.

It seems, that in Q1 2012 it doesn't work again. I have the same problem and after switching from IsEnabled=true to false there is no change in layout.

I'm using Summer template.

Hi Grzesiek,

I have tested this issue with the latest assemblies, but there seems to be no problem. Could you please elaborate more on the issue.
By design the Summer theme has no dark background when the NumericUpDown is disabled, only the buttons get greyed out.

All the best,

Hi, I have experienced similar issue on office_blue theme.

http://rad-studio.pl/Media/radnumericupdown.wmv <--- video file presenting the problem, couldnt attach it to the post

IsEnabled property of the radnumericupdown is attached to a boolean property of a viewmodel, which is initially set to true. As you can see, it has reamarkably "dark"/blue/inactive background, but it should not. When I enter mouse in the area of the control, it gets white/active/proper background. Changing value of combobox should sett mentioned bool property to false. And it causes controls' inactive state - but it impacts updown buttons only.

I'm using latest hotfix for q1.

Hello Mateusz,

I wasn't able to reproduce the issue using the Q1 2012 SP1 version of the control. Instead of ComboBox I have bound the NumericUpDown control to a CheckBox and to the ViewModel.
Please find attached a short video which illustrated my attempt.
If you could send us a sample project which reproduces the issue it will be very helpful for tracking down the source of the problem.

All the best,

Guys, are you kidding me?

I didn't have time to investigate this case, but many people are writing about this problem and you can't bind two controls together to check if it works properly on your newest radcontrols?

And why can't I attach zip file?

http://rad-studio.pl/Media/RadControlsWpfApp1.zip link to solution presenting this problem

<StackPanel Orientation="Horizontal">
    <telerik:RadToggleButton x:Name="toggleButton" Content="change updown isenabled"/>
    <telerik:RadNumericUpDown IsEnabled="{Binding ElementName=toggleButton, Path=IsChecked}"/>
</StackPanel>

this piece of xaml is more than enough to show issue. tested on sp1 and latest internal build, behaviour same as shown on video. and you can't tell me it's expected behavior. either you don't disable "inside textbox" at all, or you deal it correctly.

In addition, I'm creating official bug report.

Hello Mateusz,

Thank you for the sample project.

Initially, when you need to attach a file you have to open a support ticket, as you already did. We will research the issue and provide a fix in one of the next internal builds.
Sorry for the caused inconvenience.
