[RESOLVED] Issuing with updating textbox data in visual studio linked to mysql database

Hello,

I am using a MySQL database which is connected to Visual Studio Community Edition 2017. I have a TabControl Form with several tabs in it. I have used the following vb.net code to update textbox data: -

Private Sub btnEmployeeUpdateDetails_Click(sender As Object, e As EventArgs) Handles btnEmployeeUpdateDetails.Click

If incrementdecrement = -1 Then
incrementdecrement = 0
End If

Dim conn As New MySqlConnection
conn.ConnectionString =
"server=localhost;Port=3306;database=winery_trackers;userid=root;password=mypassword;persistsecurity info=True"
Dim da As MySqlDataAdapter = New MySqlDataAdapter("SELECT * From Employees", conn)
Dim cb = New MySqlCommandBuilder(da)


'To update the records in the mysql database
ds.Tables("Employees").Rows(incrementdecrement).Item(1) = txtEmployeeProfile.Text.ToString
ds.Tables("Employees").Rows(incrementdecrement).Item(2) = txtEmployeeName.Text.ToString
da.Update(ds, "Employees")

MsgBox("Data Updated", MsgBoxStyle.OkOnly)
End Sub

However, after I have added a Binding Navigator menu to my form, this update button control no longer works.

Thank you in advance.

Please use appropriate formatting tags when posting code snippets.

vb.net Code:

Private Sub btnEmployeeUpdateDetails_Click(sender As Object, e As EventArgs) Handles btnEmployeeUpdateDetails.Click
 
        If incrementdecrement = -1 Then
            incrementdecrement = 0
        End If
 
        Dim conn As New MySqlConnection
        conn.ConnectionString =
       "server=localhost;Port=3306;database=winery_trackers;userid=root;password=mypassword;persistsecurityinfo=True"
        Dim da As MySqlDataAdapter = New MySqlDataAdapter("SELECT * From Employees", conn)
        Dim cb = New MySqlCommandBuilder(da)
 
 
        'To update the records in the mysql database
        ds.Tables("Employees").Rows(incrementdecrement).Item(1) = txtEmployeeProfile.Text.ToString
        ds.Tables("Employees").Rows(incrementdecrement).Item(2) = txtEmployeeName.Text.ToString
        da.Update(ds, "Employees")
 
        MsgBox("Data Updated", MsgBoxStyle.OkOnly)
    End Sub

Please define "no longer works". Have you debugged that code? Have you placed a breakpoint on the first line and then stepped through the code line by line, testing the state at each step? Does the code get executed at all? If it does, exactly where and how does the actual state differ from the expected state?

To be honest, I'm not seeing why you have that code at all. The whole point of binding is that the data is moved back and forth between the data source and the UI automatically. If you enter text into those TextBoxes and they are bound to your BindingSource then that text will be automatically pushed down to the current item in your data source. You just need to make sure that you call EndEdit on the BindingSource to commit any pending changes before saving. Why do you think you need to do any manual moving of data in this case?

Yes, you are right.I have to use the Save button control. Thanks.
