Formatting text in a TextBlock

Question

Hi All.
I would like format string for EmployeeTextBlock. I created code

var bc = new BrushConverter();

TextBlock tb = new TextBlock();
tb.FontSize = 24;
tb.TextWrapping = TextWrapping.Wrap;
tb.Foreground = ((Brush)(bc.ConvertFrom("#FF1E59D6")));
tb.Inlines.Add("Edit employee ");
tb.Inlines.Add(new Run(data.Name) { FontWeight = FontWeights.Bold });

but when I assign that formated string to textbock

EmployeeTextBlock = tb;

I didn't get the result. How to fix the problem?

Thanks.

You may need to remove the old EmployeeTextBlock and add the new one into the UI.I do a little changes for your code to see the formated TextBlock:
My Xaml code is:

  <Grid Name="myGrid">  
        <TextBlock Name="EmployeeTextBlock" Width="200" Height="60" Background="Azure" MouseDown="EmployeeTextBlock_MouseDown" ></TextBlock>  
    </Grid>  

The event EmployeeTextBlock_MouseDown code is:

private void EmployeeTextBlock_MouseDown(object sender, MouseButtonEventArgs e)  
        {  
            var bc = new BrushConverter();  
            TextBlock tb = new TextBlock();  
            tb.FontSize = 24;  
            tb.TextWrapping = TextWrapping.Wrap;  
            tb.Foreground = ((Brush)(bc.ConvertFrom("#FF1E59D6")));  
            tb.Inlines.Add("Edit employee ");  
            tb.Inlines.Add(new Run("data.Name") { FontWeight = FontWeights.Bold });  
  
            myGrid.Children.Remove(EmployeeTextBlock);  
            EmployeeTextBlock = tb;  
            myGrid.Children.Add(EmployeeTextBlock);  
        }  

The result picture is like:

Try this approach too:

EmployeeTextBlock.Inlines.Clear();
EmployeeTextBlock.FontSize = 24;
EmployeeTextBlock.TextWrapping = TextWrapping.Wrap;
EmployeeTextBlock.Foreground = (Brush)bc.ConvertFrom( "#FF1E59D6");
EmployeeTextBlock.Inlines.Add( "Edit employee ");
EmployeeTextBlock.Inlines.Add( new Run( data.Name) { FontWeight = FontWeights.Bold });

Some of the properties can be set in the Designer (XAML), such as Font, Wrapping, etc. The the coding is simpler.

Sometimes you can also define a text block in XAML having some preformatted child <Run x:Name="…"> elements. Then you can access a <Run> element directly by name to change its text.
