Custome foreground color of selected item in ListView

I'm writing a listview:

<StackPanel Margin="8">
  <ListView Name="listView" ItemsSource="{Binding}">
    <ListView.View>
      <GridView>
        <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
        <GridViewColumn Header="Age" DisplayMemberBinding="{Binding Age}" />
        <GridViewColumn Header="Grade">
          <GridViewColumn.CellTemplate>
            <DataTemplate>
              <TextBlock Text="{Binding Grade}" Foreground="{Binding GradeColor}"/>
            </DataTemplate>
          </GridViewColumn.CellTemplate>
        </GridViewColumn>
      </GridView>
    </ListView.View>
  </ListView>
</StackPanel>

The foreground color of column 'Grade' is decided by the property GradeColor. It can be Green, Yello and Red.

When I select an item in the listview, the background color of the selected item turned to blue, and the foreground color of the first two column turned to white, but the foreground of the 'Grade' column didn't change to white, which cause the text is unreadable when the item is selected.

Is there any way that I can make the foreground of the 'Grade' column to be white like the other columns when the item is selected? Thx!

Hi tayyab, you can check out a Word's DLL for .NET framework.

It can both read and write RTF files in C# and the same goes for the HTML files.

For example check out this article that shows a rather simple way how to achieve a C# conversion between a HTML and Word files. You can use the same approach, the only difference would be that your input and output files need to end with an .RTF extension.

Refer this article at code project. Hope it helps

i found code from web
