How to populate an asp:textbox in TextMode=“DateTimeLocal”

Question

In my ASP.Net app, I have a textbox set to be a datepicker: <asp:TextBox ID="uxDateTimeLocalTextbox" runat="server" TextMode="DateTimeLocal"></asp:TextBox>

When the user enters the datetime, initially its a string and must be converted to DateTime format before I send it back to my SQL Server table (where that column is in datetime format):

DateTime dateTimeOriginalEmail = Convert.ToDateTime(uxDateTimeLocalTextbox.Text);    

Now, I have created functionality that will do the reverse, and populate the textbox with a value stored in the SQL table. I would think that I need to take that value and convert it back to a string. So, I tried the below (no errors were thrown) but I don't see the textbox being populated with the value from my table. I am using this method on other textboxes and dropdowns and they work fine. Any suggestions on how to get this to work? (Note: MM/DD/YYYY HH:MM AM/PM)

uxDateTimeLocalTextbox.Text = ticketInfo.Rows[0]["DateTimeOriginalEmail"].ToString();

Answer 1

uxDateTimeLocalTextbox.Text = newDate.ToString（“ yyyy-MM-ddTHH：mm”）;

Answer 2

this worked for me: (VB code but easy to change to C#)

If IsDate(dr("cnnReminder")) = True Then txtNoteReminderTS.Text = Format(dr("cnnReminder"), "yyyy-MM-ddTHH:mm")

ps. dr is a DataRow and cnnReminder a SQL DateTime

txtDate.Text = DateTime.Now.ToLocalTime().ToString("yyyy-MM-ddTHH:mm");
