[WinForm][DevExpress][GridControl]CustomColumnDisplayText Helper

标签：winform   style   blog   http   color   使用   

在实际开发中，有时候需要对GridControl中列值进行转义，譬如1转义成完成等等，一般在诸如CustomColumnDisplayText事件中能够轻松完成，为了提高代码复用性，所以对CustomColumnDisplayText进行包装

关键代码：

        /// 

        /// CustomColumnDisplayText Helper
        /// 
        /// GridView
        /// 委托
        /// 展现文字
        /// CustomColumnDisplayTextEventArgs
        public static void CusColDisplayTextHelper(this GridView girdview, Predicatestring

> fieldNameHandler, Funcobject, string> dispalyTextHandler, CustomColumnDisplayTextEventArgs e) { if (fieldNameHandler(e.Column.FieldName)) { e.DisplayText = dispalyTextHandler(e.Value); } } ///

/// CustomColumnDisplayText Helper /// /// GridView /// 委托 /// 委托 /// CustomColumnDisplayTextEventArgs public static void CusColDisplayTextHelper(this GridView girdview, Funcobject, Type, bool> valueHandler, Funcobject, string> dispalyTextHandler, CustomColumnDisplayTextEventArgs e) { if (valueHandler(e.Value, e.Value.GetType())) { e.DisplayText = dispalyTextHandler(e.Value); } } ///

///CustomColumnDisplayText Helper /// /// GridView /// 委托 /// 展现文字 /// CustomColumnDisplayTextEventArgs public static void CusColDisplayTextHelper(this GridView girdview, Funcobject, Type, bool> valueHandler, string curdispalyText, CustomColumnDisplayTextEventArgs e) { if (valueHandler(e.Value, e.Value.GetType())) { e.DisplayText = curdispalyText; } }

代码使用：

        private void gvLampConfig_CustomColumnDisplayText(object sender, CustomColumnDisplayTextEventArgs e)
        {
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("LampViDirection"), value => value.ToInt(1) == 1 ? "正向" : "反向", e);
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("LampWorkStatus"), TranLampWorkType, e);
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("CTUChNo"), value => string.Format("第{0}回路", value), e);
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("LampPhase"), TranLampPhase, e);
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("LampDeviceType"), TranLampDeviceType, e);
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("LampPower"), value => string.Format("{0} W", value), e);
            gvLampConfig.CusColDisplayTextHelper(name => name.Equals("LampIntensity"), value => string.Format("{0} %", value), e);
            gvLampConfig.CusColDisplayTextHelper((value, type) => value.ToInt(-1) == -1 && type == typeof(Int32), "不修改", e);
        }
        private string TranLampDeviceType(object type)
        {
            int _type = type.ToInt(-1);
            if (_type == 1) return "钠灯";
            if (_type == 2) return "LED灯";
            if (_type == 3) return "无极灯";
            return "--";
        }
        private string TranLampPhase(object type)
        {
            int _type = type.ToInt(-1);
            if (_type == 0) return "未知";
            if (_type == 1) return "A相";
            if (_type == 2) return "B相";
            if (_type == 3) return "C相";
            return "--";
        }
        private string TranLampWorkType(object type)
        {
            int _type = type.ToInt(-1);
            if (_type == 0) return "关闭但不删除";
            if (_type == 1) return "启用";
            if (_type == 2) return "删除";
            return "--";
        }
