DevExpress控件GridControl中的布局详解

zhu6006 · 发表于 2013-11-1 21:42:32

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");
      }
