Question

I want to check text value of text block if value is xyz. i don not want any operation but if text value is '#FF84312F' i want to set this text to foreground color of Text.
Below is my code.
How can i achieve this . Please Help me.
<TextBlock Text="#FF84312F">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=Text, RelativeSource={RelativeSource Self}}" Value="*#">
<Setter Property="Foreground" Value="Red"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>

Answer 1

Try this:
<TextBlock Text="#FF84312F">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Setter Property="Foreground" Value="{Binding Text,RelativeSource={RelativeSource Self}}" />
</Style>
</TextBlock.Style>
</TextBlock>
Or this:
<TextBlock Text="#FF84312F">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<Trigger Property="Text" Value="#FF84312F">
<Setter Property="Foreground" Value="{Binding Text,RelativeSource={RelativeSource Self}}" />
</Trigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
It will set the Foreground to the value specified by the Text property, either unconditionally or conditionally (using a Trigger).

You can use a converter to convert your string to a SolidColorBrush:
Converter class:
public class TextToSolidColorBrushConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
var color = Brushes.Black;
try
{
var converted = new BrushConverter().ConvertFromString(value?.ToString());
color = converted != null ? (SolidColorBrush) converted : Brushes.Black;
}
catch (Exception e)
{
// ignored
}
return color;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
XAML:
<Window.Resources>
<local:TextToSolidColorBrushConverter x:Key="TextToSolidColorBrushConverter"/>
</Window.Resources>
<TextBlock Text="Any text">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Setter Property="Foreground" Value="{Binding Text,RelativeSource={RelativeSource Self}, Converter={StaticResource TextToSolidColorBrushConverter}}" />
</Style>
</TextBlock.Style>
</TextBlock>

based on your Comment:
What i want is . I have to check textblock text and if text block text
is color code then assign that color code to foreground. That's it
This will change the Color of your Textblock Foreground if Binded Text Value is a Color code else default color will shown.
<TextBlock Text="{Binding Text}" Foreground="{Binding Text, RelativeSource=
{RelativeSource Self}}"/>
or
<TextBlock Text="#0FFFFF" Foreground="{Binding Text, RelativeSource=
{RelativeSource Self}}"/>
