BooleanToVisibilityConverter to collapse/show a TabItem
0
In MainWindow.xaml I have the following...
<Window.Resources>
<BooleanToVisibilityConverter x:Key="BooleanToVisibility" />
</Window.Resources>
// Tab control
<TabItem x:Name="DebugTab" Header="Debug" Visibility="{Binding Path=DebugTabState, Converter={StaticResource ResourceKey=BooleanToVisibility}}">
// Some content
</TabItem>
In MainWindow.xaml.cs I have the following...
public bool DebugTabState
{
get
{
return AppData.EnableDebuggingCheckBox;
}
}
In DebugSettings.xaml I have the following...
<CheckBox x:Name="EnableDebuggingCheckBox" Content="Enable Debugging" IsChecked="{Binding Path=EnableDebugging}" />
In DebugSettings.xaml.cs I have the following...
public bool EnableDebugging
{
get
{
return AppData.EnableDebuggingCheckBox;
}
set
{
AppData.EnableDebuggingCheckBox = value;
}
}
And finally, in AppData.cs I have the following...
private bool _enableDebuggingCheckBox;
public bool EnableDebuggingCheckBox
{
get
{
return _enableDebuggingCheckBox;
}
set
{
_enableDebuggingCheckBox = value;
OnPropertyChanged("EnableDebuggingCheckBox");
}
}
Checking and unchecking EnableDebuggingCheckBox updates the value to true or false, as expected, but the DebugTab isn't hiding or showing. Am I missing something?
Thanks!

There is no OnPropertyChanged notification from MainWindow.DebugTabState

Somewhere you havelocal:DebugSettingsand then an additional property in the view? Why not binding directly to that control (just give it anx:Name):Visibility="{Binding DebugTabState, ElementName=debugSettings, ...}? I recommend you to look into MVVM earlier, it will help you to design better UI.

@Sinatr - The checkbox is in a usercontrol separate from MainWindow where I need to hide/show the tab. My thought was that updating a public variable that holds the last state of the checkbox and implements INotifyPropertyChanged would resolve the issue.

Sure, you can implementINotifyPropertyChangedin the class holdingDebugTabState, then subscribe toPropertyChangedevent of class withEnableDebuggingCheckBoxto rise notification forDebugTabState, but this is silly.

If Appdata is a public property in MainWindow, change the binding to:
<TabItem x:Name="DebugTab" Header="Debug" Visibility="{Binding Path=AppData.EnableDebuggingCheckBox, Converter={StaticResource ResourceKey=BooleanToVisibility}}">
// Some content
</TabItem>
You can then remove MainWindow.DebugTabState.
Alternatively, in MainWindow advise to INotifyPropertyChange from AppData and raise an PropertyChanged event if EnableDebuggingCheckBox changed
