Description
I have two buttons:
<Button
Text="Button1"
Command="{Binding TheCommand}"
IsEnabled="False" />
<Button
Text="Button2"
IsEnabled="False"
Command="{Binding TheCommand}" />
For some reason, the IsEnabled property is overwritten in Button2 - this enables the button incorrectly.
Button1 is disabled this way, but when I trigger TheCommand.ChangeCanExecute(), the button enables.
Expected Behavior
Both buttons stay disabled.
The matrix of this should be an && operation:
| TheCommand.CanExecute() | IsEnabled | Final State |
|---|---|---|
| True | True | Enabled |
| True | False | Disabled |
| False | True | Disabled |
| False | False | Disabled |
Actual Behavior
The button with the command applied later overwrites the enabled state.
