DataGridView.SelectAll Method ()

 

Selects all the cells in the DataGridView.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

Public Sub SelectAll

When the DataGridView is in column-selection mode and this method is called, each column's Selected property is set to true, and each row's Selected property is set to false.

Conversely, when the DataGridView is in row-selection mode and this method is called, each row's Selected property is set to true, and each column's Selected property is set to false.

The following code example demonstrates the use of the SelectAll method. To run this example, paste the code into a form that contains a DataGridView named dataGridView1 and a Button named selectAllButton, and ensure all events are associated with their event handlers.

Private Sub selectAllButton_Click(ByVal sender As Object, _
    ByVal e As EventArgs) Handles clearSelectionButton.Click

    dataGridView1.SelectAll()

End Sub
