To reproduce: if you pin a calculator or a hyperlink column you will notice that the cells belonging to these columns remain white. However, the cells from other column types have a light blue/gray fill color for pinned state. Workaround: private void RadGridView1_CellFormatting(object sender, CellFormattingEventArgs e) { if (e.Column.IsPinned) { e.CellElement.BackColor = Color.FromArgb(235, 244, 252); } else { e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local); } }
