Devexpress在页面上查找所有控件

Question

如何在ASP.NET页面上找到所有DevExpress ASPxWebControls？

我试过这段代码：

foreach (var item in Page.Controls)
{
    if (item is ASPxWebControl)
    {
        (item as ASPxWebControl).Theme="Metropolis";
    }
}    

但它不起作用。

private void changeTheme()//this metod working in MasterPage.
        {
            for (int i = 0; i < Page.Controls[0].Controls.Count; i++)//returns masterpage
            {
                if (Page.Controls[0].Controls[i].GetType().ToString() == "System.Web.UI.HtmlControls.HtmlForm")//find htmlform in masterpage
                {
                    foreach (var item in Page.Controls[0].Controls[i].Controls)//find all controls in htmlform
                    {
                        if (item is ASPxWebControl)//reach all devexpress controls
                            (item as ASPxWebControl).Theme = "Metropolis";//change their theme
                    }
                    break;
                }
            }
            for (int i = 0; i < this.ContentPlaceHolder1.Controls.Count; i++)//find derived page's controls from masterpage
            {
                if (this.ContentPlaceHolder1.Controls[i] is ASPxWebControl)//and reach them
                    (this.ContentPlaceHolder1.Controls[i] as ASPxWebControl).Theme = "Metropolis";
            }
        }
