DataGrid styling problems


I'm going mad trying to figure out why my DataGrid is not being formatted as I want it to be. I have three columns which I style using a single DataGridTableStyle with DataGridTextBoxColumns for each column's style.

The styling is called from the function AddColumns(), below:

private void AddColumns()

                  DataGridTableStyle tableStyle = new DataGridTableStyle();
                  tableStyle.MappingName = "Order";

                  DataGridTextBoxColumn menuIDColumn = new DataGridTextBoxColumn();
                  menuIDColumn.MappingName = "ItemMenuID";
                  menuIDColumn.HeaderText = "Menu ID";
                  menuIDColumn.Alignment= HorizontalAlignment.Left;
                  menuIDColumn.Width = 10;
                  menuIDColumn.NullText = "";

                  DataGridTextBoxColumn nameColumn = new DataGridTextBoxColumn();
                  nameColumn.MappingName = "ItemName";
                  nameColumn.HeaderText = "Name";
                  nameColumn.Alignment = HorizontalAlignment.Left;
                  nameColumn.Width = 200;
                  nameColumn.NullText = "";

                  DataGridTextBoxColumn priceColumn = new DataGridTextBoxColumn();
                  priceColumn.MappingName = "ItemPrice";
                  priceColumn.HeaderText = "Price";
                  priceColumn.Alignment = HorizontalAlignment.Left;
                  priceColumn.Width = 20;
                  priceColumn.NullText = "";


                  tableStyle.AlternatingBackColor = System.Drawing.Color.WhiteSmoke;


This function is called in the form's constructor, along with row names and data types.

Thanks in advance.

It would be a good start to tell us what the problem is. . .

So what is it not doing correctly?  Is it doing some of the formatting, but not all?

It's not applying any formatting.
Are you sure your data table name is "Order"?
You didn't include your databinding statement, so I can't tell for sure.
