How do I populate a Textbox with the current system date and time?

Hello, all! First I am a complete newbie and I have a project that I need help with. I am building a Windows form application to keep track of servers and their last maintenence date. I have a simple one table SQL Express database (empty). One of my rows is set up to store the date and time. But first, I need to know how to auto populate the system date and time to a TextBox control everytime someone opens the application. I have tried using the System.DateTime method in the Textbox event properties as a string but I am doing something wrong. Thanks in advance for your help and guidence!

Time added to Detailsview TextBox Date only field


Does anyone know why a time stamp is added to a textbox field that is bound to a SQL 2008 date datatype field?

I can view the data in the database and, as expected, it only contains a date. When I bind the textbox to the db field it tacks the time '12:00:00 AM' to the end of the date?


Time in TextBox passed with current date to ObjectDataSource


Dear All.

I am developping an ASP.NET Web-Application with Visual Studio 2010 and .Net Framework 4.0.
In one of the pages I have a gridview with template fields bound to an ObjectDataSource (ConflictDetection is set to "CompareAllValues").

In one of the TextBoxes, the user can view/edit a time value (Bind("Fieldname", "{0:HH:mm"}, datetime datatype in SQL Server). The problem is that the value is passed to the DataSource not only as a time (of date #1/1/1# or another fix "root"-date) but as the time of the current date. Since this also applies to the original values, any update operation fails, because the Where-Clause sent to SQL Server tries to find a record with the time of the current day which does not exist.

I would like to add the time entered to a fix root date (#12/30/1899# like in MS Access). Is this at all possible and can someone please tell me, how to accomplish this? Thanks in advance.

Kind Regards


Date and Time Functions in SQLSERVER

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

1 DATEPART Function
2 DATENAME Function
3 DAY, MONTH, and YEAR Functions
5 DATEADD Functions
6 DATEDIFF Function
7 More SQL Server Functions

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

Built-in Functions - Date and Time Functions

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

Essential SQL Server Date, Time and DateTime Functions

The essential date and time functions that every SQL Server database should have to ensure that you can easily manipulate dates and times without the need for any formatting considerations at all.

Date/Time Conversions Using SQL Server

There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you.

Date and Time Data Types and Functions

Retain DropDown,TextBox's previously selected values after redirected from another page.


 Hi People, How are you all doing?

I have 2 pages one is SearchPage & It has DropDowns, textboxes to specify the search criteria. From the search result the user is redirected to another page when he clicks the hyperlink in the search result  where he fills in the information and again redirected to SearchPage. Now the SearchPage is posted back with no state i just want to retain the search criteria and display when user comes back. Please give me some suggestion how to get this done. I've used ViewState to save the values and check them in Page_Load but they are null.   



 Update: I've come up with this code. But the problem is The values are being retained but the Button_Click event is not being handled properly. When i Check the code even after this "DropDownList1.SelectedValue = Session["Name"].ToString();" DownList1.SelectedValue is EMPTY"" samw with DropDownList2 . please Suggest something


    protected void Page_Load(object sender, EventArgs e)
        if (IsControlsEmpty())
            if (SessionExist())
                DropDownList1.SelectedValue = Session["Name"].ToString()

Convert Update Date/Time to VB.NET



I was wondering if someone could convert this into VB.NET for me.  I'm not a PHP pro and not entirely sure what's happening here nor do I know how to get this to display the same way.

The new field is within a DetailsView, so you can give me example code as well, I'll greatly appreciate it.

Thanks.. -Jeff

PHP Code:

function updFormat($tStamp) {
	$tsTime = (strftime('%I', $tStamp) + 0) . strftime(':%M %p', $tStamp);
	// 86400 == # of seconds in a day
	$tsDays = floor($tStamp / 86400);
	$nowDays = floor(time() / 86400);
	if ($tsDays == $nowDays) $updTime = "Today at $tsTime";
	elseif ($tsDays == $nowDays - 1) $updTime = "Yesterday at $tsTime";
	else $updTime = strftime('%b ', $tStamp) . (strftime('%d', $tStamp) + 0) . strftime(', %Y' , $tStamp);

	return $updTime;
<asp:DetailsView ID="dtv_LastUpdated" runat="server" Width="100%" 
    AutoGenerateRows="False" DataSourceID="ods_MVPParcelUpdate" 
    CellPadding="1" CellSpacing="1" GridLines="None">
        <asp:BoundField DataField="Update_time" HeaderText="Parcel Data:" 

Button to copy selected item in dropdown to textbox

Hi, I found this bit of code which I tried and it isn't working. I just want to place a button next to a dropdown, and when clicked, the selected item in the dropdown will put into another textbox. <head><title>Untitled</title></head><body><script type="text/javascript">function copy() {var sel = document.getElementById("names");var text = sel.options.value;var out = document.getElementById("output");out.value += text+"\n";}</script> <select id="names"><option>Product One</option><option>Product Two</option><option>Product Three</option><option>Product Four</option></select><input type="button" onclick="copy()" value="Copy"><textarea id="output"></textarea> </body></html>   I saved this as a file and opened it in IE to test and nothing went into the textarea. Also i tried it in Firefox and the textarea said undefined each time I click the button. Can someone help to get this working?

if 'other' from drop down is selected, the respective details textbox is now validated using a req

Hi, I'm developing a system with a number of drop down lists. One of the questions relates to the light conditions at the time of the incident (for example, it could be dark, poorly lit, dusk etc...)One of the options on the drop down list is 'other'. (i argue with my client that if they're using dropdown lists, don't use other, but they disagree)The next field is 'If other, please give details'. What i'm basically looking to acheive is to say that if you select 'other' from the dropdown list, the 'if other' field becomes required using a requiredfield validator. (and the reverse too, so if you choose a pre-poulated answer such as 'dusk', the 'if other' field is not required.)I have all my other validations working fine and my drop down list is populated from an SQLDatasource (not ASP.net Items)My dropdown list id= ddlLightMy 'other' field id= txtbxLightOtherMy required validator for the 'other' field id= requiredvalLightOthermy sqldatasource id= sqldatasourcelightI'm thinking something like this, but it's not quite working for me:If ddlLight.Text = ("other") Thentxtbxlightother...Any assistance would be great. I've done this before and i'nm frustrating myself as i can't seem to work it out!ThankMike
