assign date to TextBox textmode="date" using code

when i assign the date to textBox of textmode= "date" ,it doesn't display and displays "mm/dd/yyy" although the textBox has the correct date in debugging and autopostBack is enabled .
DataTable dt= DepartMentDB.GetDepartmentById(ddlDepartment.SelectedValue.ToString());
string Managername = dt.Rows[0]["Dept_Manager"].ToString();
DateTime d = DateTime.Parse(dt.Rows[0]["Manager_hiredate"].ToString());
txtHiredate.Text = d.ToString("mm/dd/yyy");

You want "MM/dd/yyy" (notice the capital M. otherwise it would convert to minutes once its working). If it's still not working, use an invariant culture to force the conversion (since you are specifying the format directly). i.e.:
txtHiredate.Text = d.ToString("MM/dd/yyy", CultureInfo.InvariantCulture);
EDIT: Actually, it is because the textmode of date only support a specific format. Mainly yyyy-MM-dd or whatever the user specified in their culture settings. See https://stackoverflow.com/a/22747762/3419825
So either work with the text mode and go with yyyy-MM-dd, or remove the textmode, or use a framework like jQuery to add a mask

Cast your value to DateTime object

C# Date Time Picker to Text?

Im trying to get a text from a file into date format for a label.
What i currently have works great for a DateTimePicker however im wanting to now use a label to display the date rather than a DateTimePicker.
This is what currently works when getting the value to a DateTimePicker:
dateTimeMFR.Value = this.myKeyVault.MFRDate;
and this is what im attempting to make work in a label:
DateTimePicker myDate = new DateTimePicker();
myDate.Value = myKeyVault.MFRDate;
txtMFR.Text = myDate.Text;
Thanks for any help on the matter.

It depends on the format which you want to show the date in. If it should be default user format, then this:
txtMFR.Text = myKeyVault.MFRDate.ToString();
is sufficient.
You can also manually format DateTime as date or time by calling ToShortTimeString or ToShortDateString or combinations of them. Or you can provide one of the predefined string formats as explained here or here. For example:
txtMFR.Text = myKeyVault.MFRDate.ToString("T");

I don't understand why are you not just calling DateTime.ToString.
txtMFR.Text = myKeyVault.MFRDate.ToString();
If you want custom format, you can specify it like this
txtMFR.Text = myKeyVault.MFRDate.ToString("yyyy MMM dd HH:mm:ss");

First pick the format you would like to display it as:
http://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx
Then do:
txtMFR.Text = myKeyVault.MFRDate.ToString([put your selected format here]);

label1.Text = dateTimePicker1.Value.ToShortDateString();
This will do it.

datetime value in database

I updated the datetime to the datebase. It's 5/2/2012. But when I want to show this value from that database into a textbox it will show me : 05/02/2012.
Please help me to solve this problem. I want to show it's value into the textbox like the format has been updated : 5/2/2010
Thanks in advance

If you have the data as a DateTime object, then you can format its output using its ToString(string) overload with the format string "d/M/yyyy" or any other format as described here: http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx

SELECT CAST(DATEPART(MM,GETDATE()) AS VARCHAR(2))+'/'
+CAST(DATEPART(DD,GETDATE()) AS VARCHAR(2))+'/'
+CAST(DATEPART(YYYY,GETDATE()) AS VARCHAR(4))

Try this :
Textbox1.Text=datevalue.ToString("MM/dd/yyyy");

Try this ToString("d/M/yyyy") to give desired format.
If you can show me your code then I can help you more.

You can use ToString("MM/dd/yyyy") while assigning the value.
If your textbox is Textbox1 and your date value is stored in DateTime object datevalue then you should do it like this.
Textbox1.Text=datevalue.ToString("MM/dd/yyyy");

When you store this data into sql server as datetime type then the original format is lost. However, if you want to show the data without leading 0's then you can do this for your textbox.
mytextbox.Text = dt.Month.ToString().TrimStart('0') + "/" + dt.Day.ToString().TrimStart('0') + "/" + dt.Year.ToString()

It's generally poor practice to go mucking with your data with a complex query or pre-format the data before reaching your application as you lose flexibility with the results.
The data coming from SQL is properly formatted as a generic DateTime stamp - allow the application to massage it for display purposes, as #Chris-Sinclair suggests with the link to examples.
The best aproach, if using WPF, is to allow the UI element to format the text as it sees fit, that way the content of your class instances remains unmodified. It's still a DateTime object so you can do DateTime "math" or other manupiations without losing the full value.
Here is an example from elegantcode.com where the WPF UI element determines it's format:
<TextBlock Text="{Binding Date, StringFormat={}{0:MM/dd/yyyy hh:mm tt}}" />
For your speficif purpose the correct line would read
<TextBlock Text="{Binding Date, StringFormat={}{0:M/d/yyyy hh:mm tt}}" />

For doing that the best way is saving datetime into the database as a string. then after retrieving the string I can convert that to datetime. and it will show the correct format.

How to separate Time portions for comboBox

C# problem ...I am recieving from a database a datetime type 1/1/1900 08:00:00 AM and I want to take only the time portion and populate three comboBoxes with HH MM (AM or PM). I have to do the same thing for two diffent sets of data I'm getting...Have no idea how to do it..
Can anyone help?
This is what i got for the moment...I am a newbie :0)
DateTime bh = Convert.ToDateTime(puf.GetResults["Begin_Hour"].ToString());
DateTime eh = Convert.ToDateTime(puf.GetResults["End_Hour"].ToString());
string bhs=bh.ToShortTimeString();
string ehs=eh.ToShortTimeString();

What you have ought to work fine to just get the time.
You could use the ToString() method which has an overload where you can give your custom formats. Refer to this MSDN link.
So you can use bhs.ToString("t"); to print the hour, minutes and AM/PM.

Use this (dt is your DateTime object)
bhs.Format("{0:t}", dt);
The result will be in your desired format:
"4:05 PM"
You can read more here: String Format for DateTime

If you're using objects/datatables, it might be a good option to just set the DisplayMember/ValueMember properties in conjunction with the FormatString property. Set the FormattingEnabled = true, FormatString = "t", DisplayMember = ValueMember = "[Begin_Hour|End_Hour]".
Note that [|] syntax is borrowing from Regex, meaning either value will work. Then just assign the underlying datasource to the ComboBox.DataSource property. It's usually a good idea to handle display/formatting on your UI elements and keep the data elements unchanged, which is why a lot of controls provide these various data display properties.

Converting the string to datetime using asp.net

string Edate = collection["effectiveDatePicker"].ToString();
string Cdate = collection["cancelDatePicker"].ToString();
The Date I am getting is 20101112 or 20101116
Then I am doign soemthign like this to assing my Datetime variable
h.Edate= DateTime.ParseExact(collection["effectiveDatePicker"].ToString(), "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture, DateTimeStyles.NoCurrentDateDefault);
h.CDate= DateTime.ParseExact(collection["cancelDatePicker"].ToString(), "yyyyMMdd", System.Globalization.CultureInfo.CurrentCult
After saving to the data base.. I am seeing the EDate and CDate fileds somethign like this
11/10/2010
11/15/2010
with the same dates when I Submit again I am getting Error in the ParseExact bec the string I am getting is 11/10/2010 but its expecting 20101010
Can any body help me out?

You can specify the format that your dates are coming in as like this:
string Edate = collection["effectiveDatePicker"].ToString("yyyyMMdd");
string Cdate = collection["cancelDatePicker"].ToString("yyyyMMdd");
This should ensure that you are working with strings that look like what you want.

I can tell you for sure that there is a reformatting problem. I don't fully understand your code and the steps it takes (I guess you are using data binding or something similar).
The point seems that dates are initially set as yyyyMMdd, but when you postback the ToString() operator is applied to these dates, converting them to your OS's native format MM/dd/yyyy.
You must force them to be converted into yyyyMMdd again, because by default ToString will use CurrentUICulture which is not good for you.
You should show us the update code

I'm not sure what your specific question is. Because you're using DateTime.ParseExact() and are specifying a format of 'yyyyMMdd', passing in a string such as '11/04/2010' will fail.
