Example

The following example shows how to customize the layout of fields in cards via the LayoutView.CustomCardLayout event.

A card in the example contains a Photo field and a Contact Info group. In the event, the Photo field is only displayed in cards if a showPhoto flag is set. The Contact Info group is only displayed in the focused card; in other cards it’s hidden.

The result is shown below:

C#

using DevExpress.XtraGrid.Views.Layout.Events;
using DevExpress.XtraLayout;

// Indicates whether to display the Photo field in cards.
bool showPhoto = true;

void layoutView1_CustomCardLayout(object sender, LayoutViewCustomCardLayoutEventArgs e) {
    // The name of the LayoutViewField object representing the Photo card field.
    string colPhotoFieldName = layoutView1.Columns["Photo"].LayoutViewField.Name;
    // The name of the Contact Info group.
    string groupContactInfoName = "contactInfoGroup";
    // Show the ContactInfo group only in the focused card
    e.CardDifferences.AddItemDifference(groupContactInfoName, 
        LayoutItemDifferenceType.ItemVisibility, (layoutView1.FocusedRowHandle == e.RowHandle));
    // Display the Photo field if the corresponding flag is set.            
    e.CardDifferences.AddItemDifference(colPhotoFieldName, 
        LayoutItemDifferenceType.ItemVisibility, showPhoto);
}

VB.NET

Imports DevExpress.XtraGrid.Views.Layout.Events
Imports DevExpress.XtraLayout

' Indicates whether to display the Photo field in cards.
Dim showPhoto As Boolean = True

Private Sub layoutView1_CustomCardLayout(ByVal sender As Object, _
   ByVal e As LayoutViewCustomCardLayoutEventArgs)
    ' The name of the LayoutViewField object representing the Photo card field.
    Dim colPhotoFieldName As String = layoutView1.Columns("Photo").LayoutViewField.Name
    ' The name of the Contact Info group.
    Dim groupContactInfoName As String = "contactInfoGroup"
    ' Show the ContactInfo group only in the focused card
    e.CardDifferences.AddItemDifference(groupContactInfoName, _
        LayoutItemDifferenceType.ItemVisibility, (layoutView1.FocusedRowHandle = e.RowHandle))
    ' Display the Photo field if the corresponding flag is set.
    e.CardDifferences.AddItemDifference(colPhotoFieldName, _
        LayoutItemDifferenceType.ItemVisibility, showPhoto)
End Sub
