Access value of HTML Input TextBox in code behind using C# and VB.Net

on Apr 27, 2019 06:09 AM


I have an issue in inserting input text value into database table.

Issue is if I add runat=server in input text control data could not populate from my Smartcard device.

If I remove runat=server, I could not save, Error is not member..

Here is my code

<div class="row">
    <div class="col-lg-3">
        <asp:Label ID="Label1" runat="server" Text="NRIC No" CssClass="txtsize"></asp:Label>
        <input id="NRICNo" type="text" name="NRICNo" class="form-control cbo txtsize" runat="server" />
<div class="row">
    <div class="col-lg-3">
        <asp:Label ID="Label2" runat="server" Text="Gender" CssClass="txtsize"></asp:Label>
        <input id="Gender" type="text" name="Gender" class="form-control cbo txtsize" runat="server" />
<div class="row">
    <div class="col-lg-3">
        <asp:Label ID="Label3" runat="server" Text="Date Birth" CssClass="txtsize"></asp:Label>
        <input id="DOB" type="text" name="DOB" class="form-control cbo txtsize" runat="server" />
<div class="row">
    <div class="col-lg-3">
        <asp:Label ID="Label4" runat="server" Text="Birth Place" CssClass="txtsize"></asp:Label>
        <input id="BirthPlace" type="text" name="BirthPlace" class="form-control cbo txtsize"
            runat="server" />
<div class="row">
    <div class="col-lg-3">
        <asp:Label ID="Label5" runat="server" Text="Race" CssClass="txtsize"></asp:Label>
        <input id="Race" type="text" name="race" class="form-control cbo txtsize" runat="server" />
<div class="row">
    <div class="col-lg-11">
        <asp:Label ID="Label6" runat="server" Text="Photo" CssClass="txtsize"></asp:Label>
        <input id="Photo" type="text" name="BirthPlace" class="form-control txtsize" runat="server" />
<div class="row">
    <div class="col-lg-5">
        <br />
        <asp:Button ID="btnSave" runat="server" Text="Submit" CssClass="btn btn-primary" />

Hi maideen,

To retrieve the input values you have to Request.Form collection.

Check the below code.


protected void Save(object sender, EventArgs e)
private void InsertNRICData()
    string name = Request.Form["Name"];
    string nRICNo = Request.Form["NRICNo"];
    decimal gender = Convert.ToDecimal(Request.Form["Gender"]);
    string dOB = Request.Form["DOB"];
    string birthPlace = Request.Form["BirthPlace"];
    decimal race = Convert.ToDecimal(Request.Form["Race"]);
    string photo = Request.Form["Photo"];


Private Sub InsertNRICData()
    Dim name As String = Request.Form("Name")
    Dim nRICNo As String = Request.Form("NRICNo")
    Dim gender As Decimal = Convert.ToDecimal(Request.Form("Gender"))
    Dim dOB As String = Request.Form("DOB")
    Dim birthPlace As String = Request.Form("BirthPlace")
    Dim race As Decimal = Convert.ToDecimal(Request.Form("Race"))
    Dim photo As String = Request.Form("Photo")
End Sub

Private Sub Save(sender As Object, e As EventArgs) Handles btnSave.Click
End Sub
