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

I am trying to print pdf report using itextsharp pdf and all the values are correct except the values from column "Date" and "Time".
The date and time is displayed in a format like "dd/MM/yyyy tt hh:mm:ss" for eg. Date is: 08/10/2021 AM 12:00:00 and Time is: 30/12/1899 AM 07:46:37.
I have done everything mentioned below:
Inserting the date value from the datetimepicker as datetimepicker.Value.ToString("dd/MM/yyyy") and time value to be DateTime.Now.ToString("hh:mm:ss tt")
My datatype for Date and Time column in MS Access database is Date/Time
My database is showing correct formatted value and datagridview has incorrect format of Time column and generated pdf report have incorrect date and time format. My only question is how can this be possible as database consist of correct data but after displaying it in datagridview the format changes and even after printing it. Below I have attached images that will help you get the scenario.
Datatype for the column from database↓
Values in database↓
Values in Datagridview↓
you can try to set the DefaultStyle property like this
dataGridView1.Columns["YourColumn"].DefaultCellStyle.Format = "HH:mm:ss";
Or set it in the designer, whatever you like most.
In your database your Time column seems to have only a time value, but it has not. It uses the lowest possible date value, which is 30/12/1899 for an Access Database.
This happens when you only feed that column with a time, and no date. Acces (and other databases also) will simply use their lowest possible date value to fill up the missing date value.
The DataGridView therefor has no choice but to also show the date along with its time.
The property above will simply instruct the DataGridView to not show the date part, only the time part.
If you need to display the time in code in C#, you could use this
YourDateTimeVariable.ToString("T");
But, since you are storing both date and time in datetime columns, why do you store them seperate ?
You could just store them in one column, and show/use only the part you need.
EDIT
to respond to the code you posted in the comments (please add this code in your question, not in the comments)
change this
invoicesDatagridview.Rows[i].Cells[1].Value.ToString())
into this
((datetime)invoicesDatagridview.Rows[i].Cells[1].Value).ToString("T"))
in case this column can by null you will need some extra checks to avoid cast errors.
Also, the format in the GridCell willl never be used in a ToString(), you are doing the ToString() on the value, not on the display text.
Try the code above to fix this
EDIT
To respond to your comment below:
Printing code is not the point. I just want to know that how can datagridview cell value and print value be of different format –

By setting the DefaultCellStyle you tell the DataGridView what format to use to display the value. When you print this value with your own code using ToString(), how on earth should this ToString() know of the DefaultCellStyle setting ? The print code with ToString() has absolutly no connection with the DataGridView, you just pass it the value nothing more.
Look at this example
invoicesDatagridview.Rows[i].Cells[1].Value.ToString())
this can be written like this
var someValue = invoicesDatagridview.Rows[i].Cells[1].Value;
someValue.ToString();
now tell me, how should someValue.ToString() know of any format ?
The epoc of data type Date in Access is 1899-12-30, and as you display both date and time, that date is displayed as well.
In .Net you can apply the format string "T" to display hour-minute-second only. For example:
DateTime time = new DateTime(1899, 12, 30, 8, 12, 16);
Console.WriteLine(time.ToString("T"));
// 08:12:16
I get a DateTime in SQL Server DataBase and want to display it in Input:
<input class="form-control" type="date" name="ExpireDate" id="expiredate" runat="server" value="31/12/2016" style="height: 30px; width: 267px">
and here is my C# codes:
Medicine med = new Medicine();
int a = GridView1.SelectedIndex;
med.ID = int.Parse(GridView1.DataKeys[a].Value.ToString());
DataProcess bal = new DataProcess(); DataTable dt = bal.getInfo(med)
expiredate.Value = Convert.ToDateTime(dt.Rows[0][5]).ToString("dd/MM/yyyy");
I put a break point just after the last line , I saw dt.Rows[0][5] got "{2017/5/31 0:00:00}" and expiredate.Value got "31/05/2017",but it just shows nothing without error in webpage. And this DateTime record is inserted into DataBase through exactly the same Input, I just don't know how to display it in the same Input when I pull it out from DataBase.
First time to ask, many thanks!
The problem here is the format of html date input and asp.net DateTime doesn't match. Html date input displays mm/dd/yyyy but the format behind is yyyy-MM-dd.
Try using expiredate.Value = Convert.ToDateTime(dt.Rows[0][5]).ToString("yyyy-MM-dd");
Hope this helps.
It seems that you are pushing a date inside a input field which is date type. But this won't work. Because html do not support the default value for raw date format. So you have to customize the date field using a javascript. However if ou take any help from Razor Html helper then you would be able to do this either not as you are on .NET framwork. Easily you can take help from previous answers jQuerydatepicker, here you can set a default date through javascript, which will show on your input field.
So I'm populating a DATE field in MySQL table from the DateTimePicker and on the other form I need to show the date in the textbox in "dd.MM.yyyy" format, but for some reason it populates the textbox in "MM/dd/yyyy HH:MM:SS" format.
I'm populating it simply like this:
tbDate.Text = dt.Rows[0][14].ToString();
How do i change the format?
Try following code
tbDate.Text = ((DateTime)dt.Rows[0][14]).ToString("dd.M.yyyy");
I need to show the date in the textbox in "dd.MM.yyyy" format
you need to first cast the value into DateTime type and then pass your Custom Date Format String to the ToString() function
Try This:
tbDate.Text = ((DateTime) dt.Rows[0][14]).ToString("dd.MM.yyyy");
Instead of changing the format in your C# code, directly fetch the date in the required format from database.
You can use the following query to fetch the date in dd.MM.yyyy format
select DATE_FORMAT(date_column,'%d.%m.%Y') FROM table_name;
Please refer this SQLFiddle Example
And then you can use your following code as it is,
tbDate.Text = dt.Rows[0][14].ToString();
Hope this helps :)
I have this 21/10/1999 value manually inserted into the SQL database and when I retrieve it like this:
txtDOB.Text = readPatient["pDOB"].ToString();
It displays everything along with the time 12:00:00 AM. My data type for my date column is date, not datetime. So why is it displays the time as well?
((DateTime)readPatient["pDOB"]).ToString("d");
For a list of supported formats see: http://msdn.microsoft.com/es-es/library/zdtaw1bw(v=vs.110).aspx
You may try
txtDOB.Text = Convert.ToDateTime(readPatient["pDOB"]).ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
Edit: Thanks to comments saw that forgot to cast to datetime
It looks like you got your answer on how to properly format the value to a string without the time portion. But, no one has answered your other question:
So why is it displays the time as well?
This is because of mappings between SQL and .NET. In .NET a SQL "date" is stored in a DateTime object which does have time as well. To see all mappings between SQL and .NET see this: SQL Server Data Type Mappings
you can try this
txtDOB.Text=Convert.toDateTime(readPatient["pDOB"]).ToString("d/MM/yyyy");
You can use the string format parameter of the ToString to achieve any format you like,
like this:
TextBox1.Text =Convert.toDateTime(readPatient["pDOB"]).ToString("d/MM/yyyy");
Click on the datetimepicker then go to properties. There you can format your datetimepicker. Change format to custom (there few selection there) then set custom (provided in the properties menu) table with yy-MM-dd,an
DateTime dt = Convert.ToDateTime(sqdr["invdate"].ToString());
dt.Date; //To get the date only
I'm not sure how I can make the title of this question more specific.
I am working on an ASP.NET MVC3 application. There I use jQuery grid to show data from the database and have few filters. One of them should allow the user to search by date.
In my database the Date column looks like this :
I pass the selected date to the back end where I parse the date string like this :
else if (property.PropertyType == typeof(DateTime))
{
DateTime value;
if (DateTime.TryParse(rule.Data, out value))
{
selector = ExpressionEquals<T>(rule.Field, value);
}
}
Where the variable value looks like this : 03/06/2013 12:24:30.
The problem is that in my database the Date column has a different format at least from what I can see in the Management Studio, and along with that in fact I don't want to filter so specifically (The time is only for user information, but in fact I need only the date).
I need make the data from the jQuery grid usable for the kind of search I want. In fact the date string that comes from the grid looks exactly like the parsed value. In other words the rule.Data value is "03/06/2013 12:24:30".
How can use this data to filter data only by date but keeping the table column type of datetime?
Filter by range between "03/06/2013 00:00:00.000" and "03/06/2013 23:59:59.999"
Hey Leron use date format like this "03/06/2013 00:00:00" and "03/06/2013 23:59:59" may be it will help
you can use convert function sql sever e.g
SELECT field1, field2, field3, datetimefield
FROM table1
WHERE Convert(date, datetimefield) = Convert(date, #datetimeparamter)
