The object model can be pictorially described as: The data residing in a data store or database is retrieved through the data provider. Net applications for retrieving, accessing and updating data. Net object model is nothing but the structured process flow through various components.But to apprehend you need to come after the previous tutorial. So, we can move to the Data Grid View Update Database tutorial.
First of all, we will need to open the existing project.
Tag = int St Id 'changing button name from add to update btn Save.
Add some record first", "Edit Denied", Message Box Buttons. Error) End If End Sub Private Sub btn Save_Click(sender As Object, e As Event Args) Handles btn Save.
Show("Enter the ID", "Input Error", Message Box Buttons.
Show("Enter the Name", "Input Error", Message Box Buttons.
Show("Enter the Course", "Input Error", Message Box Buttons. Please consult 'SQL Server' tutorial for creating databases and database tables in SQL Server. Take the following steps: When the application is run using Start button available at the Microsoft Visual Studio tool bar, it will show the following window: In this example, let us access data in a Data Grid View control using code. Load 'TODO: This line of code loads data into the 'Test DBData Set. String", "Student City") ' adding rows Add New Row(Students, 1, "Zara Ali", "Kolkata") Add New Row(Students, 2, "Shreya Sharma", "Delhi") Add New Row(Students, 3, "Rini Mukherjee", "Hyderabad") Add New Row(Students, 4, "Sunil Dubey", "Bikaner") Add New Row(Students, 5, "Rajat Mishra", "Patna") Return Students End Function Private Sub Add New Column(By Ref table As Data Table, _ By Val column Type As String, By Val column Name As String) Dim column As Data Column = _ table. New Row() newrow("Student ID") = id newrow("Student Name") = name newrow("Student City") = city table. Add(newrow) End Sub Private Sub Button1_Click(sender As Object, e As Event Args) Handles Button1.Click Dim ds As New Data Set ds = Create Data Set() Data Grid View1.
