Example [Visual Basic]

The following example uses the Contains method to determine if a DataGridColumn with a given name exists in the GridColumnsCollection. If so, the code prints the value of the first row in the grid using the GetColumnValueAtRow method.

Note   This example shows how to use one of the overloaded versions of Contains. For other examples that may be available, see the individual overload topics.

[Visual Basic]

Private Sub GetThisColumn()
   Dim trueOrFalse As Boolean
   Dim findString As String
   findString = "FName"
   trueOrFalse = DataGrid1.GridColumns.Contains(findString)
   If trueOrFalse Then
      Debug.Print DataGrid1.GridColumns(findString). _
      GetColumnValueAtRow(DataGrid1.DataSource, 0)
   End If
End Sub
