[Solved] Issue with Font on RadGridView with Vista Theme

[Jeremy]

I am using the Vista theme for my application and am overriding the font size on the RadGridView Control.  When I updated to the 2009_1_0526_hotfix binaries the override of the font size no longer works (foreground does not seem to work either).  When I turn off the Vista theme and use the default (no theme specified) the font overrides will then work for the column headings, however they still do not apply to the data rows as it did in the 2009_1_0413 binaries.  In the 2009_1_0423 binaries they font size in the RadGridView applied to both the column heading text and the data row text.

Is this a known issue?  If so is there a fix and/or workaround?

Thank you for any help or information.

Vista Theme App.xaml.cs constructor

        public App() {
            this.Startup += this.Application_Startup;
            this.Exit += this.Application_Exit;
            this.UnhandledException += this.Application_UnhandledException;
            StyleManager.ApplicationTheme = ThemeManager.FromName("Vista");
            InitializeComponent();
        }

Default Theme App.xaml.cs constructor

        public App() {
            this.Startup += this.Application_Startup;
            this.Exit += this.Application_Exit;
            this.UnhandledException += this.Application_UnhandledException;
            InitializeComponent();
        }

Hi Jeremy,

I have tested your sample and indeed the FontSize is not being applied to the GridView cells. There are some changes in the templates which set the size of the font in different elements to enable better customization of the grid.

One workaround is to use cell style and apply it to the columns.

<UserControl.Resources>
    <Style x:Key="GridViewCellStyle" TargetType="grid:GridViewCell">
        <Setter Property="FontSize" Value="8" />
    </Style>
</UserControl.Resources>

The downside of this approach is that it will also apply the Office_Black template of the cell and you will have to restyle that one too.

That being said I will look into the changes we have made and try to revert that feature back to the state in 2009_1_0413 binaries without compromising the stylability of the grid.

I apologize for any inconvenience this might cause.
