The Data Adapter object uses Command objects to execute SQL commands.
The Data Adapter object loads the Data Set object with data and also updates changes that you have made to the data in the Data Set object back to the database.
First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.
But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
Edit Index = -1 'Bind data to the Grid View control. Sql Command Dim sql As String Dim reader As System.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.
When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.
But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.
New Edit Index 'Bind data to the Grid View control. Bind Data() End Sub Private Sub Create Data Table() Dim cmd As New System.
Dim dt = CType(Session("dt"), Data Table) 'Update the values.
