NuGet Packages: DevExpress.Win.Navigation, DevExpress.Win.VerticalGrid

Declaration

C#

public event RowChangingEventHandler RowChanging

VB.NET

Public Event RowChanging As RowChangingEventHandler

Event Data

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

Property	Description
CanChange	Gets or sets a value specifying whether the row can be changed.
ChangeType	Gets the way in which the row has changed. Inherited from RowChangedEventArgs.
Properties	Gets the processed row’s properties. Inherited from RowChangedEventArgs.
PropertyValue	Gets or sets the current value of the changed row property.
Row	Gets the processed row. Inherited from RowEventArgs.

Remarks

This example handles the vertical grid’s RowChanging event to prevent users from changing the row height. The example handles the RowChanged event to log row changes (user actions).

C#

using DevExpress.XtraEditors;
using DevExpress.XtraVerticalGrid;
using DevExpress.XtraVerticalGrid.Events;

namespace DXApplication28 {
    public partial class Form1 : XtraForm {
        public Form1() {
            InitializeComponent();
            vGridControl1.RowChanging += VGridControl1_RowChanging;
            vGridControl1.RowChanged += VGridControl1_RowChanged;
        }

        void VGridControl1_RowChanged(object sender, RowChangedEventArgs e) {
            listBoxControl1.Items.Add(string.Format("Change type: {0}", e.ChangeType));
        }

        void VGridControl1_RowChanging(object sender, RowChangingEventArgs e) {
            e.CanChange = e.ChangeType != RowChangeTypeEnum.Height;
        }
    }
}
