Finally,I have solved my problem. but there is only one issue which i want to finalize with u.
I have defined toolStrip and used toolStrip button and toolStripDropDownButton1 in the Form.
And I use this following logic which is working fine for me 
private void DisableButton()
       {
           tbRef.Visible = false;
           tbGet.Visible = false;
           tbSave.Visible = false;
           tbEdit.Visible = false;
           tbDel.Visible = false;
           toolStripDropDownButton1.Visible = false;
       }
 
       private void GetControl()
       {
           this.Text = "Student Registeration";
           string form = this.Text;
           string name = null;
           string controls = null;
           foreach (DataGridViewRow items in dGVR.Rows)
           {
               string module = items.Cells[2].Value.ToString();
               string control = items.Cells[3].Value.ToString();
               bool status = Convert.ToBoolean(items.Cells[4].Value.ToString());
               name = module.ToString();
               controls = control.ToString();
               if (form == name)
                {
                   if (tbSave.Text == controls)
                   {
                       tbSave.Visible = true;
                   }
                   if (tbEdit.Text == controls)
                   {
                       tbEdit.Visible = true;
                   }
                   if (tbDel.Text == controls)
                   {
                       tbDel.Visible = true;
                   }
                   if (tbRef.Text == controls)
                   {
                       tbRef.Visible = true;
                   }
                   if (tbGet.Text == controls)
                   {
                       tbGet.Visible = true;
                   }
                   if (toolStripDropDownButton1.Text == controls)
                   {
                       toolStripDropDownButton1.Visible = true;
                   }
               }
           }
           if (form != name)
           {
               MessageBox.Show("Contact your Administrator", "Message", MessageBoxButtons.OK, MessageBoxIcon.Stop);
               this.Close();
           }
          
          
 
       }
 
 
It is working for me but I want to use the code like the following way
foreach (ToolStripDropDownItem item in menuStrip1.Items)
{
       item.Visible = false;
       if (item.Text == name)
                   {
                       item.Visible = true;
                   }  
 
 
}
Instead of
if (form == name)
                {
                   if (tbSave.Text == controls)
                   {
                       tbSave.Visible = true;
                   }
                   if (tbEdit.Text == controls)
                   {
                       tbEdit.Visible = true;
                   }
                   if (tbDel.Text == controls)
                   {
                       tbDel.Visible = true;
                   }
                   if (tbRef.Text == controls)
                   {
                       tbRef.Visible = true;
                   }
                   if (tbGet.Text == controls)
                   {
                       tbGet.Visible = true;
                   }
                   if (toolStripDropDownButton1.Text == controls)
                   {
                       toolStripDropDownButton1.Visible = true;
                   }
               }
Is there any solution for required output????
