LayoutView.CustomCardStyle Event

Allows you to customize the appearance of a card's caption and border.

Namespace: DevExpress.XtraGrid.Views.Layout

Assembly: DevExpress.XtraGrid.v20.1.dll

Declaration

[DXCategory("Behavior")]
public event LayoutViewCardStyleEventHandler CustomCardStyle
<DXCategory("Behavior")>
Public Event CustomCardStyle As LayoutViewCardStyleEventHandler

Event Data

The CustomCardStyle event's data class is DevExpress.XtraGrid.Views.Layout.Events.LayoutViewCardStyleEventArgs.

Remarks

Handle the CustomCardStyle event to customize the appearance of a card's caption and border. To change the appearance options, use the event's Appearance parameter. The State parameter allows you to identify the card's current state.

NOTE

Changing a card's background color is not in effect in skinning paint schemes.

You can handle the CustomCardStyle event to provide different appearances for different cards. The CustomCardStyle event fires when a card is about to be painted on-screen. The currently processed card can be identified via the RowHandle parameter that specifies the card's visual position. See Rows to learn more.

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.

Examples

The following example shows how to handle the LayoutView.CustomCardStyle event to change the border color for cards that contain "London" in the City field. The event handler provides different border colors for the focused and non-focused card states.

LayoutView_CustomCardStyle_ex

using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.Layout;

private void layoutView1_CustomCardStyle(object sender, DevExpress.XtraGrid.Views.Layout.Events.LayoutViewCardStyleEventArgs e) {
    LayoutView view = sender as LayoutView; 
    string city = view.GetRowCellDisplayText(e.RowHandle, colCity);
    if (city != "London") return;
    if ((e.State & GridRowCellState.Focused) != 0)
        e.Appearance.BorderColor = Color.FromArgb(192, 192, 255);
    else
        e.Appearance.BorderColor = Color.MediumOrchid;
}
