有没有办法改变RadChart图例文本的颜色？

<style>
    .legend-text {
        color: red;
    }
</style>

<telerik:RadChart>
    <PlotArea>
        <Series>
            <!-- series configuration -->
        </Series>
        <Legend>
            <Appearance>
                <TextAppearance TextElementCssClass="legend-text" />
            </Appearance>
        </Legend>
    </PlotArea>
</telerik:RadChart>

protected void Page_Load(object sender, EventArgs e)
{
    RadChart1.Legend.Appearance.TextAppearance.TextStyle.ForeColor = System.Drawing.Color.Red;
}
