Event Data

The RowStyle event's data class is RowStyleEventArgs. The following properties provide information specific to this event:

Property	Description
Appearance	Gets the appearance settings used to paint the cells within the row currently being processed.
HighPriority	Gets or sets whether the appearance settings provided by the GridView.RowStyle event have a higher priority than the appearances specified by the GridViewAppearances.EvenRow and GridViewAppearances.OddRow properties.
RowHandle	Gets the row’s handle (position). For the ColumnView.RowUpdated event, this property specifies the previous handle (position) of the currently processed row. NewItemRowHandle value when a new row is added. Inherited from RowEventArgs.
State	Gets the current state of the processed row.

The event data class exposes the following methods:

Method	Description
CombineAppearance(AppearanceObject)	Copies the activated settings of the appearance object passed as the parameter.

Remarks

To identify the currently processed row, read RowEventArgs.RowHandle property value. The RowCellStyleEventArgs.Appearance property returns this row’s default appearance.

If you handle the GridView.RowCellStyle event to custom draw cells, an image assigned to the Appearance.Image property in the RowStyle event handler is ignored.

To change appearance settings of selected rows handle the GridView.CustomDrawCell event instead.

Important

Do not change cell values, modify the control’s layout, or change the control’s object model in the events used for custom control painting. Actions that update the layout can cause the control to malfunction.

Note

The appearance settings provided via the RowStyle event are not in effect when the grid control is printed and exported.

Example

The sample below handles the GridView.RowStyle event to highlight rows that have “Beverages” under the Category column.

C#

using DevExpress.XtraGrid.Views.Grid;

private void gridView1_RowStyle(object sender, 
DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e) {
   GridView View = sender as GridView;
   if(e.RowHandle >= 0) {
      string category = View.GetRowCellDisplayText(e.RowHandle, View.Columns["Category"]);
      if(category == "Beverages") {
         e.Appearance.BackColor = Color.Salmon;
         e.Appearance.BackColor2 = Color.SeaShell;
         e.HighPriority = true;
      }            
   }
}

VB.NET

Imports DevExpress.XtraGrid.Views.Grid

Private Sub GridView1_RowStyle(ByVal sender As Object, _ 
ByVal e As DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs) Handles GridView1.RowStyle
   Dim View As GridView = sender
   If (e.RowHandle >= 0) Then
      Dim category As String = View.GetRowCellDisplayText(e.RowHandle, View.Columns("Category"))
      If category = "Beverages" Then
         e.Appearance.BackColor = Color.Salmon
         e.Appearance.BackColor2 = Color.SeaShell
         e.HighPriority = True
      End If
   End If
End Sub
