VS 2005 What Approach For Passing Null Value To Date Field
Mar 25, 2009i'm not 100% sure about sql server but i think it doesn't accept null value for date type columns but in oracle, a date column can accept a null value. and since i'm using oracle, this is causing some problems because in my form, a textbox item bound to a date column will not accept a null value. reading thru some threads, it would seem that it is not possible to pass a null value to a date type in .Net.

May 28, 2009I'm working with a DataGridView. The DataSource for the DataGridView is set to a DataTable that I've populated with the results of a SQL query.
Then, I add an extra column to the DataGridView, a DataGridViewCheckBoxColumn. This allows the user to select a number of records in the datatable in order to save out selected files, represented by the rows of the datatable/DataGridView.
I have buttons that will programmatically check/uncheck all of these CheckBoxes, as there are frequently several hundred rows in the DataGridView. The user can also check/uncheck any number manually.[CODE..]

View 1 RepliesGetting A Value From A Grid View Into Database?
Mar 13, 2012I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.
SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1 FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName WHERE (StaffDetails.StaffID = @staffID) GROUP BY StaffDetails.StaffID, HolidayRequests.ApprovalStatus HAVING (HolidayRequests.ApprovalStatus = N'approved')

.net - Selecting A Row(s) With Multiple Columns From A Grid View And Add Them To Another Grid View?
May 6, 2009I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

Insert NULL Into Database If Form Field Is Empty Using ASP.NET & VB?
Jan 18, 2011I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into SQL it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction?
Here is the required part of the code, if you require more just let me know.
Dim rdr As SqlDataReader
Dim cmdInsert As SqlCommand = New SqlCommand()
cmdInsert.CommandText = "spPersonalDetailsInsert"
[Code].....
So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL. What does an empty form field equal? in classic ASP it was always "".
