[Solved] Retrieve Property value from a Style

[Voss Grose]

Is it possible to retrieve the Value of Property that is a child of a Style.Setter node from code?

I was trying to do something like this to found out what the background color of a row was based on the style, but couldn't figure it out:
//Setter backgroundStyleColor = (from setter in row.Style.Setters where setter.???? == "BackGround" select setter).FirstOrDefault() as Setter;

Here are my styles:


   <UserControl.Resources>
        <Style TargetType="gridView:GridViewRow" x:Key="RowStyle">
            <Setter Property="MinHeight" Value="20"/>
            <Setter Property="BackGround" Value="#FFFFFF"/>
        </Style>
        <Style TargetType="gridView:GridViewRow" x:Key="AlternateRowStyle">
            <Setter Property="MinHeight" Value="20"/>
            <Setter Property="BackGround" Value="#EDF4FA"/>
        </Style>
        <Style x:Key="GroupRowStyle" TargetType="gridView:GridViewGroupRow">
            <Setter Property="HorizontalAlignment" Value="Left" />
        </Style>
    </UserControl.Resources>

Thanks.

Hi Voss Grose,

Unfortunately Silverlight does not support this. I could get the correct setter, i.e. the one for the background but its value is always null, which is a Silverlight glitch and I hope that MS will address this sooner or later.

The only thing that I can think of is to use a static resource for the Setter.Value and then use this same resource in your code-behind, since I suppose that you want to color something else in the same color as the row:

    <UserControl.Resources>
        <SolidColorBrush x:Key="MySharedBrush" Color="Red"/>
        <Style TargetType="gridView:GridViewRow" x:Key="RowStyle">
            <Setter Property="Background" Value="{StaticResource MySharedBrush}"/>
        </Style>
    </UserControl.Resources>

Or you can read the value from the GridViewRow.Background property itself. That's all about I can think of. If this does not help -- can you please share why exactly do you need to read the value from the setter and I will try to think of a workaround.

Thanks Ross....I found a work around similar to what you suggested.

It wasn't a big deal, but thought I would try to do it the right way first before hacking it out.

thanks.
