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：

<style type="text/css">.csharpcode, .csharpcode pre{ font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em;}.csharpcode .lnum { color: #606060; }</style>

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！<style type="text/css">.csharpcode, .csharpcode pre{ font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em;}.csharpcode .lnum { color: #606060; }</style>
