VS 2010 : Saving Changes Made In DataGridView To MS Access Database?
Oct 24, 2011
I have a MS Access database file that I can view with a DataGridView, but I can not save the changes made. User should be able to modify data, and when pressing the "Save" button, these changes should be reflected on the database. That is not happening.I know this is a common question, but I have read dozens of pages trying yo get this to work.
Imports System.Data.OleDb
Public Class Form1
Dim con1 As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:JaimeTest.mdb;Persist Security Info=False")
Dim sql As String = "SELECT * FROM Table1"

I've seen used the datagridview to save the changes.
I don't use a dgv, but rather I connect directly to access and when a text field has text in it, it takes that text and searches, and updates various text boxes with the according information (finds a row, and takes all the data in the columns and adds it into their respective box). There are approximately 5-7 text boxes being used at the same time, and only a few will be changed.
How would I go about updating and saving through the VB program?
Here are some relevant pieces of code:
Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=C:\InventoryMusic.mdb")

I use a DataGridView to Add/Edit/Delete records from an Access database. Doing those 3 things is working just fine. When I try to update the database with the new Table data, nothing happens. I need to basically overwrite the table in the database with the data that was added, edited or deleted in the DataGridView. I opened the connection and got the table data like this

I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:

There are no problems during build or run time, but I do not see changes to database after the program runs.

I have a DGV bound to a data adapter. I have a button that loads a form with a reference to the DGV row. When the form is loaded, it has a TextBox to type a value, that modifies one of the cells of the row. When the form closes, the cell.value is properly modified, but saving the DGV doesn't save the new value of the cell to the DB table. I'm assuming this happens because the DGV hasn't had physical interaction. Also, this particular field is a password field, so the whole column is being hidden from the view.It seems that a DGV change is noted by physically clicking in a cell and it stores some data telling the adapter there have been changes. The thing is, this is done on a per cell basis, and only if the cell has been clicked. Well, this cell is hidden, so even though the value will be changed, you could never click or select that cell.Is there any other way to force the DGV to accept changes made to it from outside actions of just assigning the cell.value from a button click and not phsyically changing it in the DGV?

What is the best way on saving changes in datagridview into database? Whatever the user made changes in the datagridview will reflect right away in the database? The fastest and accurate way.

I have read all the posts on this and tried a million different suggestions from the posts and I still can't get this and I don't know what I am doing wrong. I am new to working with DataGrids, Table Adapters, and Binding Sources so please bear with me.I have a form with a datagrid that loads when someone makes a selection in a combobox. I want the ability to make changes in the grid when they hit the save button. This is my data connection and variables, etc.

My program runs with no errors, but the actual .accdb file does not reflect changes when I make them in the running program. Also when I fill in the text boxes and click the "Add New Item" Button, the "ID" text box displays a -1. "ID" is the primary key in my Access Database.

what I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.

I'm struggling to work with data in VB 2008, and find it extremely complicated! At first I couldn't even get a database to load, as VB 2008 kept complaining it was created with an older Jet engine.OK, I converted it to a newer Access format that VB 2008 finally accepted.
In trying to find out why changes weren't saved, I found a common problem was VB 2008 wiping out changes.OK I have told the compiler not to copy the older database file back over but to copy newer.Updates then supposedly happened --- no errors were reported --- but the changes were still not saved.It appears the update method didn't exist in the datatableadapter, but I got no error messages about that.
No update done.
I've used the tools to configure the dataset and datatableadapter.Automatic generation of methods like update, add new, delete, etc. were supposedly done.Now, when trapping the error, I'm told the update method isn't a valid one.I found little information on that. It suggested primary keys could be a cause, but adding or deleting a primary key has no effect.I can see the fill method, and it works fine.I can't see the update method. (Apparently it is in SQL which I don't know anyway.)

I'm using a MaskedTextBox, named txtDOB, into which the user types a date (the mask property is "00/00/0000"). This value is then stored in an array
Dim NewStudentFields(37) As Object
NewStudentFields(4) = txtDOB.Text
And the array is passed to a subroutine which uses the data to put into a new table row.
Some of the code from this sub:
da.InsertCommand = New OleDbCommand("INSERT INTO tblStudentInfo (FullName, FirstName, LastName, Gender, DateOfBirth, etc.etc.) VALUES (@FullName, @FirstName, @LastName, @Gender, @DateOfBirth)")
da.InsertCommand.Parameters.Add("@DateOfBirth", OleDbType.DBDate, "DateOfBirth")
If NewStudentFields(4) <> " / /" Then
dsNewRow.Item("DateOfBirth") = DateTime.Parse(NewStudentFields(4))
Else
IsDBNull(dsNewRow.Item("DateOfBirth") = True)
End If
The code executes as far as the red line which triggers the error message "Conversion from string "DateOfBirth" to type 'Integer' is not valid." There's probably something wrong with the final "If...End if", too!

Essentially what I'm trying to do is to save the value of a string() to a cell in the datagrid view. The problem is that when I close the program and reopen it the changed value isn't there... It's not saving properly.
Here is my code.
Dim BOCHURSTOTAL As Double = ((BochurimBindingSource.Current("Give_To_Bochur_Quant") * (bochurpr)) + _
(BochurimBindingSource.Current("Reg_Quant") * (regularpr)) + _
(BochurimBindingSource.Current("Priv1_Quant") * (private1pr)) + _
(BochurimBindingSource.Current("Priv2_Quant") * (private2pr)) + _
(BochurimBindingSource.Current("Priv3_Quant") * (private3pr)))
DataGridView1.CurrentRow.Cells("DGV1TotalColumn").Value = BOCHURSTOTAL
Me.Validate()
Me.BochurimBindingSource.EndEdit()
Me.BochurimTableAdapter.Update(Me.PuterDataSet.Bochurim)
