To access the values of the selected rows in a grid, you must access the SelectedRows collection.

Use the following code to write each of the selected rows to the Debug window:

To write code in Visual Basic

Dim row As Integer
For Each row In Me.C1TrueDBGrid1.SelectedRows
    Debug.WriteLine(Me.C1TrueDBGrid1.Columns(0).CellValue(row))
Next

To write code in C#

int row; 
foreach (int row in this.c1TrueDBGrid1.SelectedRows) 
{ 
    Debug.WriteLine(this.c1TrueDBGrid1.Columns(0).CellValue(row)); 
}

You can also use the grid's index to access the rows. Use the following code:

To write code in Visual Basic

Dim row As Integer
For Each row In Me.C1TrueDBGrid1.SelectedRows
    Debug.WriteLine(Me.C1TrueDBGrid1(row, 0).ToString())
Next

To write code in C#

int row; 
foreach (int row in this.c1TrueDBGrid1.SelectedRows) 
{ 
    Debug.WriteLine(this.c1TrueDBGrid1(row, 0).ToString()); 
}

For this example, the following code was added to the Button1_Click event in Tutorial 5: Selecting Multiple Rows Using Bookmarks:

To write code in Visual Basic

Dim row As Integer
For Each row In Me.C1TrueDBGrid1.SelectedRows
    Debug.WriteLine(Me.C1TrueDBGrid1(row, 1).ToString())
Next

To write code in C#

int row; 
foreach (int row in this.c1TrueDBGrid1.SelectedRows) 
{ 
    Debug.WriteLine(this.c1TrueDBGrid1(row, 1).ToString()); 
}

What You've Accomplished

The Last name of each composer in a selected row is returned in the Debug window:
