Hi so I was trying to populate my Textbox a data from a RFID card but my Textbox isn't Postingback and I dont really know why.
Here is my Mark up:
<body><form id="form1" runat="server"><asp:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server"></asp:ScriptManager><div class="jumbotron"><div class="containcer"><img src="Images/logo3.png" alt="Online Evaluatuation System" /><div class="row"><asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server"><ContentTemplate><asp:Button ID="cmdLogin" CssClass="btn btn-xs btn-danger" runat="server" Text="CLICK HERE TO LOGIN" OnClick="cmdLogin_Click" /></div></ContentTemplate><Triggers><asp:AsyncPostBackTrigger ControlID="cmdLogin" EventName="Click" /></Triggers></asp:UpdatePanel><div class="row"><asp:UpdatePanel ID="UpdatePanel2" runat="server"><ContentTemplate><div class="row"><asp:Label ID="statement" runat="server">Pleas Tap your ID in the RFID reader.</asp:Label></div><asp:TextBox ID="txtID" runat="server" AutoPostBack="true"></asp:TextBox></ContentTemplate><triggers><asp:AsyncPostBackTrigger ControlID="txtID" /></triggers></asp:UpdatePanel></div></div></div></div><center><div class="footer"><p>© UPHSD - MOLINO 2013</p><p>Developed by Pharisees Group™</p></div></center></form></body></html>
and here is my code in populating the textbox:
public void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
//if (!comPort.IsOpen) return;
Thread.Sleep(100);
strBuffer = comPort.ReadExisting();
txt.Text = Convert.ToString(strBuffer.ToString());
txtID.Text = txt.Text;
comPort.Close();
}
