helo Guna,

There may be other ways to do this using Custom editors but this may be a quick and simple way of doing what you need. Please can you try the below

Designer File
namespace RadGridView_Basic_C
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components;
  
        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
  
        #region Windows Form Designer generated code
  
        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.radGridView1 = new Telerik.WinControls.UI.RadGridView();
            this.radSpinEditor1 = new Telerik.WinControls.UI.RadSpinEditor();
            ((System.ComponentModel.ISupportInitialize)(this.radGridView1)).BeginInit();
            ((System.ComponentModel.ISupportInitialize)(this.radSpinEditor1)).BeginInit();
            this.SuspendLayout();
            // 
            // radGridView1
            // 
            this.radGridView1.Location = new System.Drawing.Point(0, 0);
            this.radGridView1.Name = "radGridView1";

            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(457, 556);
            this.Controls.Add(this.radSpinEditor1);
            this.Controls.Add(this.radGridView1);
