I am using the sample datetimepicker code from the Microsoft web site in a databound datagridview. This works fine if I use the combobox dropdown button and select a date. Is there a way to use today's date by default and not specifically selecting it?
[Code]...
I need to compare the date that is entered with today's date minus some number of work days.
I used dateinterval.day, but that is the actual day, not the work day. i don't see a "simple" way to get work days.
For example, my number is 3, so i want 3 work days (M-F) not 3 days.
We have a very massive system where reports are run off dates from specific days through to today's date using various definitions of "GenerateSalesReport(DateStart, Date.Now)". For debugging purposes I want to simulate reports that occurred in the past so I need to change the object "Date.Now" to a specific date from the past on my development environment. Can you override date.Now?

I'm working in visual studio 2005 and developing a windows form that has a datagridview on it.
One of the cells is a Calendar Column type (custom made). I pulled the code for it off the internet - it basically allows the user to select the date from a small calendar.
When the date is changed, it gets the correct value and it also saves into the database with the correct value.
The problem is that it doesn't load onto the grid with the correct value. In fact, no matter what date I enter in, it always displays it as 1 day earlier. e.g. If I saved it to the database as 4/19/2012, it displays it as 4/18/2012.
I verified that there's no other column in the query that retrieves the data for the grid that contains the value it's displaying.
I have been on a database project for a while now. I wanted to be able to make changes to my database using the update command of a Datagridview control.However, I have been faced with a series of unsuccessful outcomes.I want to do this how do I go about it?

View 5 RepliesI am beginning to work with .NET technology after several years of VB6 and C++ and I want to learn as fast as possible.
My problem is with a DGV. It shows the prices of several store items, and I intend to let the user modify those prices by entering a % in a textbox (radio button states if that % is positive or negative) or by editing cell by cell manually.
As editing prices is kind of sensitive, what I do is loop through the DGV, add or substract the % engtered in the corresponding column and ask for a confirmation after whole DGV loop is done. If user agrees, DB is updated with new values. No problem here.
If user denies (in case he/she made a mistake), I restore grid's DataSource to a copy I made before calculating new percentages and this automatically refreshes my grid to its original state.
The issue is that if a user denies the operation for a 2nd time, this 2nd execution of the code fails at showing the original values, disabling the pseudo-rollback function.
Here is the code:
