Hi Sagar55,

//Here i am change your code and i am using MenuStrip Control.

//Declare MenuStrip Control Object (Assign Global)
MenuStrip ms = new MenuStrip();

private void button1_Click(object sender, EventArgs e)
       {
           ds = clsdb.getDataset("SP_MENU");
           int j = ds.Tables[0].Rows.Count;           
           for (int i = 0; i < j; i++)
           {
               ToolStripMenuItem tsmMain=new ToolStripMenuItem(ds.Tables[0].Rows[i]["tx_name"].ToString());
              tsmMain.DisplayStyle=ToolStripItemDisplayStyle.Text; 
              ms.Items.Add(tsmMain);
              CallSubMenu(ds.Tables[0].Rows[i]["tx_code"].ToString(),tsmMain);
               
           }
           this.Controls.Add(ms);
       }

       private void CallSubMenu(string sName, ToolStripMenuItem main)
       {
           SqlParameter[] par = new SqlParameter[1];
           par[0] = new SqlParameter("@sub_menu", SqlDbType.VarChar);
           par[0].Value = sName;
           dssub = clsdb.getDataset("SP_SUBMENU",par);
           int p=dssub.Tables[0].Rows.Count ;
           for (int i = 0; i < p; i++)
           {
               ToolStripMenuItem tsmSub=new ToolStripMenuItem(dssub.Tables[0].Rows[i]["tx_name"].ToString());
              tsmSub.DisplayStyle=ToolStripItemDisplayStyle.Text; 
              main.DropDownItems.Add(tsmSub);
              CallSubMenu(dssub.Tables[0].Rows[i]["tx_code"].ToString(),tsmSub);
               
           }
       }
   }

I hope this code helpful to you.

Cheers :)
