VB.NET-将Datagridview中的更改保存到数据库

Question

I have set Oracle connection to DatagridView, via manager. Line for this is:

  Me.UsersTableAdapter.Fill(Me.MyDataSet._Users)

Now I want to save all changes made in Datagridview to DB. Tried this but not working:

 Me.UsersTableAdapter.Update(Me.MyDataSet._Users)

What am I missing here ?

Answer 1

1.Maybe you are missing validate() and endEdit() ?

Try
    Me.Validate()
    Me.UsersBindingSource.EndEdit()
    Me.UsersTableAdapter.Update(Me.MyDataSet._Users)
    MsgBox("Update successful")

Catch ex As Exception
    MsgBox("Update failed")
End Try

2. Do you have primary key for the table?

Update

Fix the code I present -

Me.UsersBindingSource.EndEdit()

Answer 2

Solved. Correct synthax is:

Try
    Me.Validate()
    Me.UsersBindingSource.EndEdit()
    Me.UsersTableAdapter.Update(Me.MyDataSet._Users)
    MsgBox("Update successful")

Catch ex As Exception
    MsgBox("Update failed")
End Try
