【原创】DevExpress控件GridControl中的布局详解

在进行DevExpress控件GridControl的使用时，因控件的灵活性，所以用户会经常进行拖动控件的列，以达到自己满意的样式，

但下次再打开时系统就会重新还原到原有的布局风格，为了能够保持用户之前设置的风格，下次再打开时依然保持原有的风格。

在gridView中有两个方法：SaveLayoutToXml（保存布局）,RestoreLayoutFromXml（恢复布局)

 以下是具体的代码：

        private string systempath = "C:\\Program Files\\";
        /// <summary>
        /// 保存风格
        /// </summary>
        /// <param name="moduleid"></param>
        /// <param name="saveType"></param>
        private void SaveLayout(string moduleid, string saveType)
        {
            string path = systempath + "窗体风格\\" + moduleid+"\\";
            string file = saveType + "view.xml";
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
           m_gridView.SaveLayoutToXml(path+file);
        }
        /// <summary>
        /// 加载风格
        /// </summary>
        /// <param name="moduleid"></param>
        /// <param name="saveType"></param>
        private void LoadLayout(string moduleid, string saveType)
        {
            string path = systempath + "窗体风格\\" + moduleid + "\\";
            string file = saveType + "view.xml";
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            if (!File.Exists(path + file))
                return;
            m_gridView.RestoreLayoutFromXml(path + file);
        }
        /// <summary>
        /// 布局变化时产生事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void m_gridView_Layout(object sender, EventArgs e)
        {
            SaveLayout(m_controlManager.Owner.ModuleId, "Master");
        }

        /// <summary>
        /// gridcontrol load Event
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param>
        private void m_gridControl_Load(object sender, EventArgs e)
        {
            SaveLayout(m_controlManager.Owner.ModuleId, "Default");

            LoadLayout(m_controlManager.Owner.ModuleId, "Master");
        }
