Hi, Einar,

If you haven't added a tablestyle, then you'll have to do something different.

The grid class from my article grid project automatically creates one, based on the column definitions you supply it.

If you're not explicitly using that class, if you're using your own, you'd have to do something like...

DataGridTableStyle style = new DataGridTableStyle();
style.MappingName = "MyDataTableName";

DataGridTextBoxColumn fld1 = new DataGridTextBoxColumn(); 
fld1.HeaderText = "Job #";
fld1.MappingName = "JobNumber";
fld1.Width = 55;

DataGridTextBoxColumn fld2 = new DataGridTextBoxColumn();
fld2.HeaderText = "Job Description";
fld2.MappingName = "Descript";
fld2.Width = 115;

style.GridColumnStyles.AddRange(new DataGridColumnStyle[] {fld1, fld2 });

myGrid.TableStyles.Clear();
myGrid.TableStyles.Add(style);

Then you'll have a tablestyle.
