Highlighting data on mouse-over keeps your grid readable. If you don't like built-in mouse hover style of DataGrid for WPF, you can quickly change it to match your theme, or disable it completely. It only takes a line of code, or a single property set in your XAML markup. In XAML view, locate your tag. It should look something like the following: Add MouseOverBrush="Yellow" to the markup: And you're done! When you run your application, moused over cells will be highlighted in yellow. If you prefer working in code, try adding the following to your project: Visual Basic
Me.c1datagrid1.MouseOverBrush = New System.Windows.Media.SolidColorBrush(Colors.Yellow)
this.c1datagrid1.MouseOverBrush = new System.Windows.Media.SolidColorBrush(Colors.Yellow);
Again, that's it! When you run your application and mouse over a row or column, it'll look like the following image: For more easy ways to customize your Grid, including information on templates, check out the documentation.
