GridConditionalFormatDescriptor. Appearance Property''s Precedence

Hi, I am trying to set rows that have a certain field''s value < 0 to a certain BackColor using the GridConditionalFormatDescriptor. For Example: gridConditionalFormatDescriptorShortPos.Appearance.AnyCell.BackColor = Color.Salmon; However when I initially format my grid I am setting the color of all the grid columns conditionally (depending of whether the column is readonly or editable, etc..) using: col.Appearance.AnyCell.BackColor where col is a GridColumnDescriptor. I am noticing that no matter if I create my ConditionalFormatter before or after I set all the GridColumnDescriptor''s color the formatter has no effect. However if I comment out the code that sets my ColumnDescriptors colors then the conditional formatting works just fine for the wanted rows. Which takes precedence the conditional formatting using GridConditionalFormatDescriptor or the appearance of the GridColumnDescriptors?

Hi Erly, quick tip: If you handle QueryCellStyleInfo event as follows as Tooltip will show up that tells you where the cell gets its Appearance from: private void groupingGrid1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e) { e.Style.CellTipText = e.TableCellIdentity.Info; } Regarding your initial question: The appearance of the column descriptor has predence over conditional format. If you want to give the row higher precedence, you could try that with a base styles: Assign a base style to the column descriptor and assign style properties directly to the conditional format. Below is code for a modified InitializeComponent method for the "CategoryView" example. Replace it in the form1.cs code. All cells in conditial row will be orrange and override the columns color. #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent() { Syncfusion.Windows.Forms.Grid.Grouping.GridTableBaseStyle gridTableBaseStyle1 = new Syncfusion.Windows.Forms.Grid.Grouping.GridTableBaseStyle("Orange");
