I am filtering dataview using my Date Column but the result is not proper because the Field value also stores time, so I want to convert this Date Field to only Date during Filter. How can I achieve this? Here is my code. And the actual value I am getting in the Dataset Field "CreationDate" is a DateTime field which is like
2010-01-21 14:35:25.203
2010-01-22 12:55:18.033
2010-01-26 12:10:06.990
But I only want to neglet time value and want to compare Date only.
[Code]....
I'm trying to set the "time" value stored in a date time field, in other words, I want to change the value
05-13-2010 08.47.34
to
05-13-2010 00.00.00
or
05-13-2010 23.59.59
What statement would I use to accomplish this?
This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then
Try
If pasDate <= System.DateTime.MinValue Then
Return Nothing
Else
Return CType(pasDate, DateTime)
End If
Catch ex As NullReferenceException
Return Nothing
End Try
Else
Return Nothing
End If
End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.
My work is done properly all good with this query

I have some issues about retrieveing and storing date information to my database (ms sql server 2005).My data column is a DateTime, and i have set my web.config globalization culture is set to "en-gb"
When i retrieve date from the datebase it appears as dd/MM/yy, that's fine. But i cannot insert a new date as same format?! It will only accept MM/dd/yy or yy/mm/dd.Right now i'm using this code to correct the error:

I'm using VS 2005 and SQL SERVER 2005,now i have a table with only two columns (their types: DateTime and SmallDateTime)
i key in some new records.Now I want to use GridView to retrieve that table, and use Calendar.SelectedDate as a parameter used in WHERE statement,I press "Test Query" and pop out a window "Parameter Values Editor",
here comes the problem.. how come the "DbType" is always 'Date'?After i click the list and select 'DateTime', but next time it will recover back to 'Date'I have to go to the source code find the "Dbtype" and change from "Date" to "DateTime" manually EVERYTIME~
Like This:
From:<SelectParameters>
<asp:ControlParameter ControlID="Calendar1" DbType="Date" Name="Date" PropertyName="SelectedDate" />
</SelectParameters>
To:<SelectParameters>
<asp:ControlParameter ControlID="Calendar1" DbType="DateTime" Name="Date" PropertyName="SelectedDate" />
</SelectParameters>
if i don't do this, it will lead to error:the version of sql server in use does not support datatype 'date'
It's weird that my original datatype is "DateTime" but the Dbtype is ALWAYS "Date" and lead to error everytime.
I'm looping through an ArrayList and creating a column in a DataTable from each field. One of my fields is a DateTime field, and I've noticed that when I create the columns, it's being changed to a String, but I need it to still be a DateTime field for sorting. I'm trying to do this, but it's not quite working.

View 1 RepliesI am very new to ASP .NET and am getting above error when trying to insert a new record into a SQL database. I have turned on Option Explicit On so the default date of 01/01/1900 does not get assigned to this field automatically. Since most of the people in the database will not have a date of death, I need to have "blank" deathDate. When I run the stored procedure within SQL and choose pass null value, the Insert Procedure works fine. When I attach to Web Form, however, I get String was not recognized as a valid DateTime error. How can I set it so Null values are accepted into this date field.
