Web Forms :: Compare Date To Another In String Format
Jan 21, 2011
I have a textbox control with a calendarExtender. I want to make the user select a date subsequent to Today. I have a public function, called display_error, written that displays some text in case of validation not successfull. So in this case, the validation of the date inserted by user would look like
[Code]....
So, my textBox.text is a string, which I need to convert to Date to compare it to Today. Here's what I've written
[Code]....
I've tried different methods, like Parse, but I keep getting the same error, String was not recognized as valid DateTime.
Dim script = "<script language = javascript>" & _ "window.setTimeout('ShowTime(true, [?????])', 1000);</script>" ClientScript.RegisterStartupScript(Me.GetType, "iniciar", script)
I must write a dateTime parameter in string format, but I'm not achieving the goal. I've tryed various time formats (Eg. 2011/02/10 17:05:00), without success. Ps: I know... when I try with only the date, its ok. But I need the time too.
Here is what I'm trying to achieve: The user enters in the textbox a date. It can be: 20.04.2010 or 20/04/2010 or 01Apr2010 or Apr 01 2010...
Any other formats should be forbidden. When the user leaves the textbox then the date should be displayed as 01-Apr-2009. I already tried but I got only when am entering the numbers only like (21-04-2010) but I want to entering the string like apr, jan, nov .
I am getting error while inserting date in sql database :
My SQL Table Structure isÂ
Column Name | DB TYPEID ---- INT -----Autogenerated -- PKey
Proj_StartDate ---- Date
In Application i have created a class for holding variable properties then linking this class to another class where my insert method is residing :
public class ProjectMaker {Â public string Proj_StartDate { get; set; } }
Now the Class in which i am linking above Class Property is :
 public class ProjectMaker_DB { public static void InsertRecord(ProjectMaker model) { var cmd = new SqlCommand { CommandType = CommandType.StoredProcedure, CommandText = "[dbo].[sproc_INSERT_d_project_p]"
[Code] ....
That was my Class library project , Now here's my Coding for button click event in startup project :Â
protected void SubmitProject_OnServerClick(object sender, EventArgs e) { if (SubmitProject.InnerHtml.Contains("Submit")) { #region Submit Section try { var rec = new ABC_Library.ProjectMaker()
[Code] ....
I am getting start date from Ajax calendar extender toolkit's Selected Date .
After clicking Submit Button it gives me error : "Input string was not in a correct format" ...
I am trying to check for a condition such that a date in an input control (textbox) is not greater from a date 1 years from current date(exactly) and also it should not be less than a date 1 year back from current date. for eg. if today's date is "21/dec/1990" then usen cannot enter a date in textbox which is less than 21/dec/89 and it should not be greater than 21/dec/1991. for this i first tried to confirm the greater than condition, i wrote the following code:
I have a program that is using credit card info and the expiration date is selected by the user clicking a dropdownlist for the month and a dropdownlist for the year. I want to show a label message if the user tries to proceed while the month and year are evaluated as being earlier that the current month/year.
I have this example and it gives me exception "Conversion from string x to dateTime is invalid"
here is my method to validate Datetime.
Example Date string : "27/03/1985"
Public Function validateDateColumn(ByRef FieldName As String) As Boolean
Try If IsDate(FieldName) Then Dim actualDate As DateTime = CDate(FieldName) Dim DtLicExp As DateTime = CDate(actualDate.ToString("d", Thread.CurrentThread.CurrentCulture)) FieldName = DtLicExp.ToString("MM/dd/yyyy") Return True End If Catch ex As Exception 'FieldName &= "Format must be MM/dd/yyyy" Return False End Try End Function
validate this date string formate to datetime.
I want to convert this date "27/03/1985" to datetime.

I have the following date in string format "2011-29-01 12:00 am" . Now I am trying to convert that to datetime format with the following code:
DateTime.TryParse(dateTime, out dt);
But I am alwayws getting dt as {1/1/0001 12:00:00 AM} , Can you tell me why ? and how can I convert that string to date.
EDIT:
I just saw everybody mentioned to use format argument. I will mention now that I can't use the format parameter as I have some setting to select the custom dateformat what user wants, and based on that user is able to get the date in textbox in that format automatically via jQuery datepicker.
dates appearing in this gridview display as M/d/yyyy + time for example 12/31/2010 00:00:00
My Question: i need a way to display date as d/M/yyyy with no time for example 31/12/2010 usually i do this by setting the gridview properties htmlencode=false and dateformatstring="{0:M-dd-yyyy}" but in this case the gridview dont show any field because it bind data only at run time
