Textbox textmode is DateTimeLocal
提问by Dinesh Persaud
I have a textboxand i would love it to be formatted. fortunately for me, i can get this done by changing the textmode = DateTimeLocal. Exactly what I want. Additionally, I would like to load this textbox with default values rather than leaving it with dd/mm/yy __:__:__. I can change the text if it is a regular textbox (single mode) or even a datetime textbox. but i cannot change it with DateTimeLocalmode. some help please. thank you.
我有一个textbox，我希望它被格式化。对我来说幸运的是，我可以通过更改textmode = DateTimeLocal. 正是我想要的。此外，我想使用默认值加载此文本框，而不是将其保留为dd/mm/yy __:__:__. 如果文本是常规文本框 ( single mode) 甚至日期时间文本框，我可以更改文本。但我不能用DateTimeLocal模式改变它。请一些帮助。谢谢你。

You will have to format the DateTime to a valid Date and Time string that can be parsed, here is one that works:
您必须将 DateTime 格式化为可以解析的有效日期和时间字符串，这是一个有效的：
txtDateTimeLocal.Text = DateTime.Now.ToLocalTime().ToString("yyyy-MM-ddTHH:mm");
For more details on what other attributes you can set, see: http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#local-date-and-time-state-(type=datetime-local)

Try setting the whole datetime format including seconds and milliseconds, worked for me.
尝试设置包括秒和毫秒在内的整个日期时间格式，这对我有用。
txtStartTime.Text = DateTime.Today.ToString("yyyy-MM-ddTHH:mm:ss.ss");

If you want to set a TextBox's DateTime dynamically from a database then you can use this code:
如果要从数据库动态设置 TextBox 的 DateTime，则可以使用以下代码：
DataTable dtTemp = (DataTable)ViewState["DataSet"]; // this are temporary table
TextBox txtFromDate = (TextBox)gridEditBloackHomework.Rows[e.NewEditIndex].FindControl("txtFromDate");
TextBox txtToDate = (TextBox)gridEditBloackHomework.Rows[e.NewEditIndex].FindControl("txtToDate");
string c = dtTemp.Rows[e.NewEditIndex]["FromDate"].ToString();
DateTime FromDate = Convert.ToDateTime(dtTemp.Rows[e.NewEditIndex]["FromDate"]);
DateTime ToDate = Convert.ToDateTime(dtTemp.Rows[e.NewEditIndex]["ToDate"]);
DateTime dtFromDate = FromDate.AddHours(-2);
DateTime dtToDate = ToDate.AddHours(-2);
txtFromDate.Text = dtFromDate.ToLocalTime().ToString("yyyy-MM-ddTHH:mm").ToString();
txtToDate.Text = dtToDate.ToLocalTime().ToString("yyyy-MM-ddTHH:mm");
