How to set focus by the Enter key

Hello,
Lookup editors and grid handle the Enter key. This explains the fact that an event is not fired. You can inherit the DetailViewForm template and override its ProcessDialogKey method to handle the Enter key. Below is some sample code (add a new module to our previous sample project).

C#
using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using System.Data;  
using System.Drawing;  
using System.Text;  
using System.Windows.Forms;  
using DevExpress.ExpressApp;  
using DevExpress.ExpressApp.Templates;  
using DevExpress.ExpressApp.Utils;  
using DevExpress.ExpressApp.Win.Templates;  
namespace WinSolution.Module.Win {  
    public class MyDetailViewForm : DetailViewForm {  
        private Control GetActiveControl(ContainerControl containerControl) {  
            Control result = containerControl.ActiveControl;  
            if((result != null) && (result is ContainerControl)) {  
                result = GetActiveControl((ContainerControl)result);  
            }  
            return result;  
        }  
        protected override bool ProcessDialogKey(Keys keyData) {  
            Keys keyCode = keyData & Keys.KeyCode;  
            if((keyCode == Keys.Return) && ((keyData & Keys.Modifiers) == Keys.None)) {  
                Control activeControl = GetActiveControl(this);  
                if(activeControl != null) {  
                    return SelectNextControl(activeControl, true, true, true, true);  
                }  
            }  
            return base.ProcessDialogKey(keyData);  
        }  
        public MyDetailViewForm() : base() { }  
    }  
}  

Then override the OnCreateCustomTemplate method of the WinSolutionWindowsFormsApplication class defined in the WinApplication.cs unit:

C#
using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using DevExpress.ExpressApp.Win;  
using DevExpress.ExpressApp.Templates;  
using DevExpress.ExpressApp;  
using WinSolution.Module.Win;  
namespace WinSolution.Win {  
    public partial class WinSolutionWindowsFormsApplication : WinApplication {  
        ...  
        protected override IFrameTemplate OnCreateCustomTemplate(string name) {  
            if(name == TemplateContext.View) {  
                return new MyDetailViewForm();  
            }  
            return base.OnCreateCustomTemplate(name);  
        }  
    }  
}  

Finally, you can remove the layout.OptionsFocus.EnableAutoTabOrder = false; line from the ViewController1 class. After that the Enter moves focus to the last control on your form. By improving the ProcessDialogKey method, you can implement circular tabbing through controls, if needed.
Thanks,
