DataGridView in Visual Basic .NET

This lesson describes the DataGridView control


This control displays a table-like grid display while the data can come from a data source such as a DataSet or BindingSource.
Of course, you can add rows and columns directly to the control without using the mentioned data source objects.

The DataGridView provides many properties for customizing appearance of the grid.
For example, you can change column header styles and cell border styles, determine whether rows and columns are resizable, and determine whether the control displays tooltips and errors in data cells.

Visual Basic can automatically create a DataGridView bound to a BindingSource and associated with a BindingNavigator.
To do this, create a data source and drag a table from the Data Sources window onto a form.

First click the little "Add New Data Source" button in the Data Source window, and then in the new dialog choose the database as data source type:

data source

Click next so you can select the data you want to retrieve:

data source objects

Now just drag and drop the table to the form:

data source table



Note: you could do the very same with the code below:

    Dim table As New DataTable
    Dim connection As New SqlConnection(My.Settings.ConnectionString)
        Dim command As SqlCommand = connection.CreateCommand
        command.CommandText = "SELECT * FROM Students"
        StudentsGrid.DataSource = table
    Catch ex As Exception
    End Try
