  <asp:ScriptManager ID="ScriptManager1" runat="server">
  	</asp:ScriptManager>
  	<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
  		<ContentTemplate>
  			<asp:Label ID="label" runat="server" Text="Label"></asp:Label>
  		</ContentTemplate>
  	</asp:UpdatePanel>
  	<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server">
  		<ContentTemplate>
  			<asp:GridView ID="grid" runat="server" AutoGenerateSelectButton="True" OnSelectedIndexChanging="grid_SelectedIndexChanging">
  			</asp:GridView>
  		</ContentTemplate>
  	</asp:UpdatePanel>
  
  protected void Page_Load(object sender, EventArgs e)
  	{
  		if (!Page.IsPostBack)
  			this.BindGrid();
  
  	}
  
  	private void BindGrid()
  	{
  		this.grid.DataSource = new String[] { "A", "B", "C", "D" };
  		this.grid.DataBind();
  	}
  
  	protected void grid_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
  	{
  		this.label.Text = grid.Rows[e.NewSelectedIndex].Cells[1].Text;
  		this.UpdatePanel1.Update();
  	}

  in grid_RowCommand or button event, after assigning value to the the parent label control then call the Update method of the Parent UpdatePanel

   

  Thanks,
