If you replace a List View’s default Action, you may also want to hide the Edit Action column without deactivating the Edit Action displayed on the toolbar. This topic describes how to solve this task.

In an ASP.NET Web Forms module project, create the following View Controller class.

C#

using DevExpress.Web;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Web.Editors.ASPx;
// ...
public class HideEditColumnController : ObjectViewController<ListView, Contact> {
    protected override void OnViewControlsCreated() {
        base.OnViewControlsCreated();
        ASPxGridListEditor gridListEditor = View.Editor as ASPxGridListEditor;
        if (gridListEditor != null) {
            ((ASPxGridViewContextMenu)gridListEditor.ContextMenuTemplate).ControlsCreated +=
                HideEditColumnController_ControlsCreated;
        }
    }
    void HideEditColumnController_ControlsCreated(object sender, EventArgs e) {
        ASPxGridViewContextMenu contextMenu = (ASPxGridViewContextMenu)sender;
        contextMenu.ControlsCreated -= HideEditColumnController_ControlsCreated;
        foreach (GridViewColumn column in contextMenu.Editor.Grid.Columns) {
            if (column is GridViewDataActionColumn && ((GridViewDataActionColumn)column).Action.Id == "Edit") {
                column.Visible = false;
            }
        }
    }
}

VB.NET

Imports DevExpress.Web
Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Web.Editors.ASPx
' ...
Public Class HideEditColumnController
    Inherits ObjectViewController(Of ListView, Contact)

    Protected Overrides Sub OnViewControlsCreated()
        MyBase.OnViewControlsCreated()
        Dim gridListEditor As ASPxGridListEditor = TryCast(View.Editor, ASPxGridListEditor)
        If gridListEditor IsNot Nothing Then
            AddHandler CType(gridListEditor.ContextMenuTemplate, ASPxGridViewContextMenu).ControlsCreated, AddressOf HideEditColumnController_ControlsCreated
        End If
    End Sub
    Private Sub HideEditColumnController_ControlsCreated(ByVal sender As Object, ByVal e As EventArgs)
        Dim contextMenu As ASPxGridViewContextMenu = CType(sender, ASPxGridViewContextMenu)
        RemoveHandler contextMenu.ControlsCreated, AddressOf HideEditColumnController_ControlsCreated
        For Each column As GridViewColumn In contextMenu.Editor.Grid.Columns
            If TypeOf column Is GridViewDataActionColumn AndAlso CType(column, GridViewDataActionColumn).Action.Id = "Edit" Then
                column.Visible = False
            End If
        Next column
    End Sub
End Class

As a result, the Edit Action column is hidden:
