DataGridTableStyle problem

Question

Hi. I was trying to play with the datagrid example at that page: http://www.c-sharpcorner.com//Code/2002/Mar/AddingControlsToDataGridTA.asp But I am getting error telling me that some properties doesn't exist for predefined the DataGridTableStype page like that: ...\Form1.cs(91): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'RowHeadersVisible' ...\Form1.cs(92): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'HeaderBackColor' ...\Form1.cs(93): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'AllowSorting' ...\Form1.cs(94): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'HeaderBackColor' ...\Form1.cs(95): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'HeaderForeColor' ...\Form1.cs(96): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'HeaderFont' ...\Form1.cs(97): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'GridLineColor' ...\Form1.cs(98): 'System.Windows.Forms.DataGridTableStyle' does not contain a definition for 'PreferredRowHeight' I looked in the doc and these object properties really exist, what is my problem? I am using MDE2003. Maybe it has something to do with the fact that in my piece of code, I am not loading anything in the datagrid yet just trying to set the datagrid style. Thanks, Matt
