    Hi Ramraj,

    Thank you for writing.

    You can create a custom GridGroupContentCellElement class, where you can add the button:
    public class CustomCellElement : GridGroupContentCellElement
    {
        public CustomCellElement(GridViewColumn column, GridRowElement row)
            : base(column, row)
        {
        }
     
        RadButtonElement buttonElement;
     
        protected override void CreateChildElements()
        {
            buttonElement = new RadButtonElement();
            buttonElement.Text = "testButton";
            buttonElement.StretchHorizontally = false;
            buttonElement.StretchVertically = false;
            buttonElement.Alignment = ContentAlignment.MiddleRight;
            this.Children.Add(buttonElement);
            base.CreateChildElements();
        }
     
        protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(GridGroupContentCellElement);
            }
        }
    }

    You can use the CreateCell event to change the default cell element with the custom one:
    void radGridView1_CreateCell(object sender, GridViewCreateCellEventArgs e)
    {
        if (e.CellType == typeof(GridGroupContentCellElement))
        {
            e.CellElement = new CustomCellElement(e.Column, e.Row);
        }       
    }

    I hope this will be useful.
