Update A Database From A Datagrid
Aug 14, 2008
I am having a problem getting updates and deletions to go back to my SQL database.Adding a new record is fine.But if I try to delete or change a record and then use a button to update I get this error:Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.I have tried to use the update command that is part of the SQL command builder but it gives me an error as well.[code]

I am trying updating a record. It seems like I did all the right things but I can't seem to update my database. I'm not sure if my update button is functioning as it should be.
Private Sub UpdateButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpdateButton1.Click
Dim cb As New OleDb.OleDbCommandBuilder(da5)
While count5 < MaxRecords5
cells5 = 0
[Code] .....
Whenever I edit the datagrid, and press update, it doesn't really update the database.

I'm at the moment busy with a project for school. Well I have a datagridview that displays all of the employees within the company. But I want to be able to change, delete or add new employees in the datagridview and then save it in the actual database. I used this code to do that.
Me.Validate()
Me.TblPersonnelBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.DtsPersonnel)
But when I run my program and click on the save button I get this error message:
Application Exception was unhandled
TableAdapterManager contains no connection information. Set each TableAdapterManager TableAdapter property to a valid TableAdapter instance.How can I get around this? I think it has to do that my dataset exists out of 1 table but actually it contains items from 2 tables. Would this be the problem?I need to have the dataset like that though otherwise other parts of the program won't work.

I have this program im making it is supposed to be a basketball game monitor. The user enters two teams and the 12 players on each team then it has you pick the 5 active players and takes you to the run form where you can start the game once started you can add things like fouls and baskets made and attempted if a player gets 5 fouls or you hit stop clock you change which players are active and its supposed to update the database through the dataset and dataadapter but it doesnt seem to update the database with the info put in the datagrid view.
Here is the code of the run form i will also attach source in zip file if needed to point out mess ups
Update: When you hit resume game after change of players is when it puts zero on everyone again.

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I have a main form with player information (it's a sports application). To add or edit a player the user presses a button which opens another form. They either add or edit from this point. When they click 'OK', it saves the data to the database table then goes back to the main form. The amended or new info doesn't appear. If they close the application, then reopen, the new info appears in the datagrid now.
how I can get the datagrid to refresh once I press 'OK' on the input form?

I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?

I have a mature VB6 program that depends heavily on flexgrids for the display.It appears that DataGrids are somewhat of a replacement for flexgrid?I need to update individual cells over and over and I don't see how to address a single cell. Appears to me that most samples are tied to a database which I don't have.If I set up a datagrid that is say 3x3, how do I read and write from and to say the center cell?

I have a datagrid that is populated using a stored procedure.

I'm trying to refresh the datagrid after using the SQL UPDATE statement. The data changes physically in the database but the datagrid is not affected. The data is changed only after i restart the program.
How can i get the datagrid to refresh or update? I have tried using, among other code, the refresh() method, but it does not work.
