Hi yogaraj,

I was not able to reproduce such an issue at my end. Please try the sample code snippet.

ASPX:
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

C#:
RadGrid rgrdSample;
protected void Page_Init(object source, System.EventArgs e)
{
    rgrdSample = new RadGrid();
    rgrdSample.ID = "RadGrid1";
    rgrdSample.MasterTableView.DataKeyNames = new string[] { "OrderID" };
    rgrdSample.AllowPaging = true;
    rgrdSample.AutoGenerateColumns = false;
    rgrdSample.AllowSorting = true;
    rgrdSample.MasterTableView.Height = Unit.Pixel(700);
    rgrdSample.Width = Unit.Pixel(700);
    rgrdSample.ClientSettings.Scrolling.AllowScroll = true;
    rgrdSample.NeedDataSource += new GridNeedDataSourceEventHandler(rgrdSample_NeedDataSource);
 
 
    GridColumnGroup columnGroup = new GridColumnGroup();
    columnGroup.Name = "group1";
    columnGroup.HeaderText = "group1";
    rgrdSample.MasterTableView.ColumnGroups.Add(columnGroup);
 
    columnGroup = new GridColumnGroup();
    columnGroup.Name = "group2";
    columnGroup.HeaderText = "group2";
    rgrdSample.MasterTableView.ColumnGroups.Add(columnGroup);
 
    columnGroup = new GridColumnGroup();
    columnGroup.Name = "group3";
    columnGroup.HeaderText = "group3";
    rgrdSample.MasterTableView.ColumnGroups.Add(columnGroup);
 
    GridButtonColumn btn = new GridButtonColumn();
    btn.Text = "Edit";
    btn.CommandName = "Edit";
    rgrdSample.MasterTableView.Columns.Add(btn);
 
    GridBoundColumn boundColumn;
    boundColumn = new GridBoundColumn();
    boundColumn.DataField = "OrderID";
    boundColumn.HeaderText = "OrderID";      
    boundColumn.HeaderStyle.Width = Unit.Pixel(300);
    boundColumn.ColumnGroupName = "group1";
    rgrdSample.MasterTableView.Columns.Add(boundColumn);
 
    boundColumn = new GridBoundColumn();
    boundColumn.DataField = "ShipCountry";
    boundColumn.HeaderText = "ShipCountry";     
    boundColumn.HeaderStyle.Width = Unit.Pixel(300);
    boundColumn.ColumnGroupName = "group1";
    rgrdSample.MasterTableView.Columns.Add(boundColumn);
 
        
    boundColumn = new GridBoundColumn();
    boundColumn.DataField = "ShipVia";
    boundColumn.HeaderText = "ShipVia";     
    boundColumn.HeaderStyle.Width = Unit.Pixel(300);
    boundColumn.ColumnGroupName = "group1";

    boundColumn = new GridBoundColumn();
    boundColumn.DataField = "Freight";
    boundColumn.HeaderText = "Freight";     
    boundColumn.HeaderStyle.Width = Unit.Pixel(300);
    boundColumn.ColumnGroupName = "group1";
    rgrdSample.MasterTableView.Columns.Add(boundColumn);
 
    boundColumn = new GridBoundColumn();
    boundColumn.DataField = "CustomerID";
    boundColumn.HeaderText = "CustomerID";      
    boundColumn.HeaderStyle.Width = Unit.Pixel(300);
    boundColumn.ColumnGroupName = "group2";
    rgrdSample.MasterTableView.Columns.Add(boundColumn);
 
    boundColumn = new GridBoundColumn();
    boundColumn.DataField = "ShipCity";
    boundColumn.HeaderText = "ShipCity";      
    boundColumn.HeaderStyle.Width = Unit.Pixel(300);

    rgrdSample.MasterTableView.Columns.Add(boundColumn);
 
    this.PlaceHolder1.Controls.Add(rgrdSample);
}
 
void rgrdSample_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    rgrdSample.DataSource = GetDataTable("SELECT  * FROM Orders");
}    
 
public DataTable GetDataTable(string query)
{
    String ConnString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
    SqlConnection conn = new SqlConnection(ConnString);
    SqlDataAdapter adapter = new SqlDataAdapter();
    adapter.SelectCommand = new SqlCommand(query, conn);
 
    DataTable myDataTable = new DataTable();
 
    conn.Open();
    try
    {
        adapter.Fill(myDataTable);
    }
    finally
    {
        conn.Close();
    }
 
    return myDataTable;
}

Thanks,
Shinu

Hi  Shinu, Thanks for the reply. I'm using same way of coding only. I suspect this issue is beacuse of i'm doing data row cell hiding (set cell visible false) to acheive the colspan between the cells. Refer the attachment, right side header row and data row columns are collapesed afer the horizontal scroll. any solution?
