Updating database through datagrid vb net

Recommendation would be to create the dataset as a permanent item in your project (it becomes a separate editable item in your project), with the tables registered in there.

Once you do that, the datagridview will allow you to do updates (several of my CRUD applications have dozens of this kind of setup going on).

In short - any unique, non-nullable column would work.

OK) End Try End Sub Private Sub cmd Update Profile_Click(By Val sender As System. it meets the criteria, and could have been picked as the primary key).

Form 'SQL Connection Public cs As New Sql Connection("Data Source=PC\SQLEXPRESS; Initial Catalog=my Database; Integrated Security=TRUE") Public da As New Sql Data Adapter("SELECT * FROM tbl Prod", cs) Public ds As New Data Set Public cmb As New Sql Command Builder(da) 'Access Connection Dim Conn As Ole Db Connection Dim Comm As Ole Db Command Dim Olea As Ole Db Data Adapter Dim Sql As String Private Sub My Conn() Try Conn = New Ole Db Connection("Provider = oledb.4.0; Data Source = C:\my ") Conn.

You define the tables, and their data access procs for each type of CRUD, once in a single place: the datagridview then automatically know which procedures to use and how to call them (which parameters to send and what populates the params).

For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.

Note: Keep in mind that this Update is different than a SQL UPDATE statement.
