I have a customcontrol which render a textbox. I've also a style that set the color of the background based on some conditions as follows:
<Style x:Key="ArtParamStyle" TargetType="av:DC_Base">
<Setter Property="Background" Value="{StaticResource EditableAreaBrush}" />
<Style.Triggers>
<DataTrigger Binding="{Binding Path=Info.Upd.IsAutoCalc}" Value="True">
<Setter Property="Background" Value="Red" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=Forced}" Value="True">
<Setter Property="Background" Value="LightGreen" />
</DataTrigger>
</Style.Triggers>
</Style>
Initially as the value of my textbox is autocalculated, the background is correctly red. If I also set the Forced as true (by ticking a chebckbox) I've a weird result, the border of textbox is lightgreen but background not.
It seems to be a strange color, a combination of red and lightgreen. As test, if I set the "IsAutoCalc" color as Transparent, the trigger works correctly. How can I solve this?
your code seems to be correct. But I provide you my sample:
XAML:
<Window.Resources>
<Style x:Key="ArtParamStyle" TargetType="TextBox">
<Setter Property="Background" Value="Yellow" />
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding Bool1}" Value="True"/>
<Condition Binding="{Binding Bool2}" Value="False"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="Red" />
<Setter Property="BorderBrush" Value="Red" />
</MultiDataTrigger>
<DataTrigger Binding="{Binding Bool2}" Value="True">
<Setter Property="Background" Value="LightGreen" />
<Setter Property="BorderBrush" Value="LightGreen" />
</DataTrigger>
</Style.Triggers>
</Style>
</Window.Resources>
<Grid>
<StackPanel>
<TextBox Style="{StaticResource ArtParamStyle}" Height="50" Margin="4"/>
<CheckBox IsChecked="{Binding Bool1}"/>
<CheckBox IsChecked="{Binding Bool2}"/>
</StackPanel>
</Grid>
In this case I used Multidatatrigger to set red background when Bool2(your forced) is not checked.
MainWindow.cs:
public partial class MainWindow : Window, INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChaged(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
private bool bool1;
public bool Bool1
{
get { return bool1; }
set { bool1 = value; RaisePropertyChaged("Bool1"); }
}
private bool bool2;
public bool Bool2
{
get { return bool2; }
set { bool2 = value; RaisePropertyChaged("Bool2"); }
}
public MainWindow()
{
InitializeComponent();
this.DataContext = this;
}
}
Probably your problem is related to your custom control.
