When I hit Enter key to go to the next row
I like when the group arrives. The group did not stop.
And go to the next row.
But the group arrives. collapse is


namespace RadGridViewSelectNextRow
{
    public partial class Form1 : Form
    {
        private RadGridView grid = new RadGridView();
        private RadButton btn = new RadButton();
        private Random rnd = new Random();
        private List<Dummy> dataSource = new List<Dummy>();
 
        public Form1()
        {
            InitializeComponent();
            this.grid.Dock = DockStyle.Fill;
            this.grid.Parent = this;
            this.grid.AutoSizeColumnsMode =  GridViewAutoSizeColumnsMode.Fill;
             
            this.btn.Dock = DockStyle.Bottom;
            this.btn.Text = "Move to next row";
            this.btn.Click += btn_Click;
            this.btn.Parent = this;
 
            for (int i = 0; i < 100; i++)
            {
                this.dataSource.Add(new Dummy
                {
                    Id = rnd.Next(0, 6),
                    Name = "Name number " + i
                });
            }
 
            this.grid.DataSource = this.dataSource;
 
            this.Load += Form1_Load;
 
            this.grid.KeyUp += new System.Windows.Forms.KeyEventHandler(this.radGridView1_KeyUp);
 
        }
 
        void Form1_Load(object sender, EventArgs e)
        {
            GroupDescriptor descriptor = new GroupDescriptor("Id");
            this.grid.GroupDescriptors.Add(descriptor);
            this.grid.MasterTemplate.AutoExpandGroups = true;
        }
 
        void btn_Click(object sender, EventArgs e)
        {
            this.grid.GridNavigator.SelectNextRow(1);
        }
        private void radGridView1_KeyUp(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                this.grid.GridNavigator.SelectNextRow(1);
                this.grid.BeginEdit();
            }
 
        }
    }
 
    public class Dummy
    {
        public int Id {get;set;}
        public string Name {get;set;}
    }
}

Hello Ali,

Thank you for writing back.

In that case you need to change the default behavior of the grid. You can create a custom GridGroupRowBehavior:
public class MyRowBehavior : GridGroupRowBehavior
{
    protected override bool ProcessEnterKey(KeyEventArgs keys)
    {
        return false;
    }
}

The behavior can be used as follows:
((BaseGridBehavior)this.grid.GridBehavior).UnregisterBehavior(typeof(GridViewGroupRowInfo));
((BaseGridBehavior)this.grid.GridBehavior).RegisterBehavior(typeof(GridViewGroupRowInfo), new MyRowBehavior());

I hope this helps.

Regards,
George

I'm so sorry about it.
I implemented it on monday as shown above and ran it successfully, but next day it does not work anymore.
I can reproduce it on my pc that it dont work, but on another computer it does run normally. Both systems does have the same source code from monday. So I didn't changed it.

No breakpoint in my custom behavior hit anymore. And yes, the behavior is registered and nowhere removed or unregistered. Do you have any suggestions for me?

I thought, maybe it's not the correct registeration type when register the behavior.

regards

Hello Bjorn,

Thank you for contacting us.

From the provided information I find it hard to understand what the root of the problem may be, moreover that without any change in your code the behavior changed. 

That is why I would like to kindly ask you to provide me with a sample project where this behavior is reproduced so I can investigate this case properly. 

Looking forward to your response.

Regards,
George
