            for (int i = 0; i < tmp.Length; i++)

            }

            textBlock.FontSize = 16;
            textBlock.FontWeight = FontWeights.Black;
            SolidColorBrush scbrush = new SolidColorBrush();
            scbrush.Color = Colors.Black;
            textBlock.Foreground = scbrush;

            textBlock.HorizontalAlignment = HorizontalAlignment.Center;
            radwindow1.Header = textBlock;
            radwindow1.Show();
        }


        private void radwindow1_LocationChanged(object sender,RoutedEventArgs e)
        {
            moreInfo.InvalidateArrange();
        }


        #endregion

//左键菜单
graphic.MouseLeftButtonDown += new MouseButtonEventHandler(sw_graphic_MouseLeftButtonDown);
 graphic.MouseLeftButtonUp += new MouseButtonEventHandler(sw_graphic_MouseLeftButtonUp);

void sw_graphic_MouseLeftButtonDown(object sender,MouseButtonEventArgs e)
{
         e.Handled = true;
}

 void sw_graphic_MouseLeftButtonUp(object sender,MouseButtonEventArgs e)
 {
            Graphic g = sender as Graphic;
            string url = "../ysq/page2.aspx?stype=2&ylz=" + HttpUtility.UrlEncode(g.Attributes["YLZMC"].ToString());
            //弹出窗体
            ClickOpenDetailInfo(g.Attributes["YLZMC"].ToString(),url);
}

效果如下图，这个窗口能保证每次只弹出一个。
