时分秒(HHHH:mm:ss)控件的2种实现方式

Posted 2020-06-07

_{方式一、基于DEV TextEdit控件实现时分秒控件}

public virtual void textEdit1_FormatEditValue(object sender, DevExpress.XtraEditors.Controls.ConvertEditValueEventArgs e) {
            TextEdit objectControl = sender as TextEdit;
            int hour = 0;
            int minute = 0;
            int seconds = 0;
            if (e.Value != null && !string.IsNullOrEmpty(e.Value.ToString())) {
                if (!e.Value.ToString().Contains(":") || e.Value.Equals("0")) {
                    GetHourMinutSeconds(ref hour, ref minute, ref seconds, Convert.ToInt32(e.Value));
                    e.Value = hour.ToString().PadLeft(4, ‘0‘) + ":" + minute.ToString().PadLeft(2, ‘0‘) + ":" + seconds.ToString().PadLeft(2, ‘0‘);

                    if ((hourArr[2]!=null && Convert.ToInt32(hourArr[2]) > 59) || (hourArr[1]!=null && Convert.ToInt32(hourArr[1]) > 59)) {
                        GetHourMinutSeconds(ref hour, ref minute, ref seconds,e.Value);
                        if (hour < 10000) { //时间不能大于9999:59:59
                            e.Value = FormatTime(hour, minute, seconds);
                        } 
                    } 
                }
            } else {

        private void GetHourMinutSeconds(ref int hour, ref int minute, ref int seconds, object initializeHour) {
            if (initializeHour != null) {
                string[] hourArr = initializeHour.ToString().Split(‘:‘);
                TimeSpan ts = new TimeSpan(Convert.ToInt32(hourArr[0]), Convert.ToInt32(hourArr[1]), Convert.ToInt32(hourArr[2]));

方式二、使用key_down,key_press,key_up事件实现时分秒控件_{（该方式控制光标显示不友好）}

                DevExpress.XtraEditors.TextEdit editTxt = (DevExpress.XtraEditors.TextEdit)(sender);
                char[] txtArray = editTxt.Text.ToCharArray();
                if (editTxt.SelectedText.Contains(":") || (editTxt.SelectionStart < txtArray.Length && txtArray[editTxt.SelectionStart].Equals(‘:‘))) {
                    e.Handled = true;
                }
            }
        }

        int oldSelectionStart = -1;//记录keyPress事件中的光标的起始位置
        string newEditTxt = string.Empty;//记录当光标没有选中字符，则替换掉同光标的位置的字符后的新的字符串
        /// <summary>
        /// 控制修改后的时间符合标准格式

                        if (editTxt.SelectionLength == 0) {

                            if (editTxt.SelectionStart < txtArray.Length && (!‘:‘.Equals(txtArray[editTxt.SelectionStart]))) {

                                    isSelectFirstColon = true;//表示光标停留在第一个冒号的位置
                                } else {
