[DevExpress]条件设置GridControl RepositoryItem是否可编辑

在项目开发中,并不是每个RepositoryItem都可以编辑,往往是有条件性的,需要譬如当A列等于“AA”的时候,B列才可编辑,实现起来在ShowingEditor事件中最为方便,并且加入toolTip提示显得人性化。

代码如下:

        private void gvLampConfig_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e)

        {

            GridView _view = sender as GridView;

            if (_view.FocusedColumn.Name == "colSavePowerGp1")//当列等于colSavePowerGp1

            {

                string _type = _view.GetRowCellDisplayText(gvLampConfig.FocusedRowHandle, "OptStatusText_gp1");

                if (!_type.Equals("节能"))//当列OptStatusText_gp1的列值不等于OptStatusText_gp1

                {

                    e.Cancel = true;

                    ShowToolTip(toolTipController, "提示", "当是【调光状态】是节能模式情况,可以设置该值!");

                }

            }

        }

        public static void ShowToolTip(ToolTipController toolTip, string title, string content)

        {

            Point _mousePoint = Control.MousePosition;

            toolTip.ShowHint(content, title, _mousePoint);

        }

代码效果:

为了调高代码复用性,方便后续使用,可以这样子封装一下:

        /// <summary>

        /// 设置RepositoryItem是否可编辑

        /// 说明:

        /// 在ShowingEditor事件中使用

        /// </summary>

        /// <param name="view">GridView</param>

        /// <param name="focusedColumnName">需要设置的列名称</param>

        /// <param name="conditonHanlder">判断委托</param>

        /// <param name="toolTip">ToolTipController</param>

        /// <param name="title">当条件委托成立的时候提示标题</param>

        /// <param name="content">当条件委托成立的时候提示内容</param>

        /// <param name="e">CancelEventArgs</param>

        private void CustomShowingEditorWithToolTip(GridView view, string focusedColumnName, Func<object, bool> conditonHanlder, ToolTipController toolTip, string title, string content, CancelEventArgs e)

        {

            if (view.FocusedColumn.Name.Equals(focusedColumnName))

            {

                if (conditonHanlder(view.GetFocusedRow()))

                {

                    e.Cancel = true;

                    Point _mousePoint = Control.MousePosition;

                    toolTip.ShowHint(content, title, _mousePoint);

                }

            }

        }

代码使用:

        private void gvLampConfig_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e)

        {

            GridView _view = sender as GridView;

            CustomShowingEditorWithToolTip(_view, "colSavePowerGp1", arg => ((LampSelfRunCfgParamter)arg).OptStatusText_gp1 != "节能", toolTipController, "提示", "当是【调光状态】是节能模式情况,可以设置该值!", e);

        }

希望有所帮助!
