Update Command Cell After Click

[Роберт]

Problem:
What should be done to force the Command button to change its content right away, without changing the focus to other cell?

 

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls.UI;

 

namespace GridApp

{

    public partial class RadForm1 : Telerik.WinControls.UI.RadForm

    {

        public RadForm1()

        {

            InitializeComponent();

            radGridView1.Rows.Add(new object[1] { "zero" });

            radGridView1.Rows.Add(new object[1] { "one" });

            radGridView1.Rows.Add(new object[1] { "two" });

            radGridView1.Rows.Add(new object[1] { "three" });

            radGridView1.Rows.Add(new object[1] { "four" });

        }

 

        private void radGridView1_CommandCellClick(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

        {

            switch (e.ColumnIndex)

            {

                case 1:

                    RadButtonElement b = (RadButtonElement)((GridCellElement)radGridView1.CurrentCell).Children[0];

                    b.Tag = true ^ (bool)b.Tag;

                    break;

                default:

                    break;

            }

        }

 

        private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)

        {

            if (e.ColumnIndex == 1)

            {

                RadButtonElement b = (RadButtonElement)e.CellElement.Children[0];

                b.ImageAlignment = ContentAlignment.MiddleCenter;

                b.TextAlignment = ContentAlignment.MiddleCenter;

                // set bool data as switch

                if (b.Tag == null) b.Tag = false;

                b.Text = ((bool)b.Tag) ? "locked" : "open";

            }

        }

    }

}

All changes happen only after the cell is validated.
In other words: how to validate a cell manually?
I can't find Cell.Validate() command..

How to change the current cell?
