VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?
Jul 30, 2010How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console.

View 1 RepliesUnbound DataGridView + CSV
Nov 15, 2011First form has 1 listbox and 2 buttons. Second form has 1 datagridview and 1 button. The first form opens the csv and list the location+filename of the CSV file. When the CSV files are listed in the listbox, the user can edit the selected csv file in listbox through edit button, when edit button is pressed, the second form will show as dialog and automatically opens the CSV files in DataGridView. The user will edit some fields and save and the second form will autoclose. Now here's the problem, when i select another CSV file in the listbox and press the edit button, the previous CSV still shows, even other CSV files I select, still the previous CSV file was showing.

Unbound Checkboxes In DataGridView?
Jun 21, 2010I'm working on a project where I've loaded a database into a DGV. I also have an additional unbound checkbox column for the users to select entries with. I have code in place to read the selected rows and save them into a CSV string, which is then saved in the usersettings. All this works fine.
PROBLEM AREA:
I'm trying to reverse this effect so that when the DGV loads, the checkboxes that the user selected previously are checked (and the others left unchecked). I've debugged this extensively, and using watches have confirmed that all the values in the loops are right, and the conditionals are all kicking correctly, but it seems the code I'm using to actually check the boxes doesn't work. I've searched dozens of web pages, msdn white papers, and forums, but no suggestions will check the darned box. Below is some example code.[CODE...]
In debugging, it seems the value for the Cells IS changed, but the checkbox never gets selected. The try/catch was just to pick any error messages (but there are none with this code). What am I doing wrong here?
