column

The DataGridColumn to search for.

The index of the specified DataGridColumn in the DataGridColumnCollection. The default value is -1, which indicates that the specified column object is not found.

Use this method to determine the index number of a specified DataGridColumn derived object in the DataGridColumnCollection. If the specified DataGridColumn object is not found, an index of -1 is returned.

The following example demonstrates how to use the IndexOf method to determine the index of a DataGridColumn derived object in a DataGridColumnCollection.

void getIndex ( Object src, EventArgs e ) {
   myLabel.Text = "The indexes of the columns: <br>";

   foreach ( DataGridColumn column in myGrid.Columns ) {
      myLabel.Text += column.HeaderText + " = " + 
         myGrid.Columns.IndexOf ( column ) + "<br>";
      }
}

Sub getIndex ( src As Object, e As EventArgs )
   myLabel.Text = "The indexes of the columns: <br>"
   Dim column As DataGridColumn
   For Each column In myGrid.Columns
      myLabel.Text = column.HeaderText & " = " &_
         myGrid.Columns.IndexOf ( column ) & "<br>"
   Next column
End Sub
