Hi Jim,
Instead of changing through SetValue, try using ModifyStyle method. Here is the code snippet.
if (this.gridControl1.Data[i, j] != null)
{
// this.gridControl1.Data[i, j].SetValue(GridStyleInfoStore.FontProperty, "Arial");
style.Font.Facename = "Arial";
style.Font.Bold = true;
this.gridControl1.Data[i, j].ModifyStyle(style.Store, StyleModifyType.ApplyNew);
}
Refer to the sample for details
Let us know if you need further assistance.
Regards,
Madhan.
