Try this:
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindUsers();
}
}
You shouldn't put a form element inside another form:
<form accept-charset="UTF-8" role="form">
<fieldset>
...
<asp:Button ID="submit" runat="server" class="btn btn-lg btn-success btn-block" Text="Submit" OnClick="submit_Click" />
</fieldset>
</form>
remove the inner form.
[Update]
Another problem is the "ID" property of the button.
change it to something else, other than "submit".

Hello Everyone,
I am building multi-web application pages using the Default.aspx, Default.aspx.cs and Confirm.aspx and Confirm.aspx.cs. The problem that I am having is that when I click "Confirm" before clicking "Calculate," the event handler displays the "Click the Calculate button before the confirm" at the bottom of the page. It does that even if the Calculate button is clicked before the Confirm and also displays again when I reload the page. How can I get this to only display if the session state value of SalesPrice is null? Otherwise, it will redirect to the confirm page. Here is Default.aspx.cs and other file:
You can do one thing. If you want to get the total calculation first, then disable the confirm button and clicking on the calculate button will enable the button as follows:
<asp:Button ID="Button1" runat="server" Enabled="false" />
protected void btnCalculate_Click(object sender, EventArgs e)
{
Button1.Enabled = True;
if(Session["TotalPrice"] != null)
{
lblMsg.Text = "Please click here to see total calculation";
}
}
protected void Button1_Confirm(object sender, EventArgs e)
{
if(Session["SalesPrice"] != null)
{
Response.Redirect("Confirm.aspx");
}
}
Note: Please follow the naming convention for the event names. Button1 To btnConfirm.
Update 1 - Try the below tested code:
<asp:Button ID="btnCalculate" runat="server" Text="Calculate" OnClick="btnCalculate_Click" />
<asp:Button ID="btnConfirm" runat="server" Text="Confirm" OnClick="btnConfirm_Click" />
<asp:Label ID="lblMsg" runat="server"></asp:Label>
private int buttonWasClicked = 0; //Kept a variable type of int and with a default value 0
protected void btnCalculate_Click(object sender, EventArgs e)
{
buttonWasClicked = 1; //If clicked, then 1
Session["value"] = Convert.ToInt32(buttonWasClicked); //Then kept in session
lblMsg.Text = "Total Price - 10,000";
}
protected void btnConfirm_Click(object sender, EventArgs e)
{
if (Session["value"] != null) //If session not null, then redirect page
{
Response.Redirect("CustomerDetails.aspx");
Session["value"] = null; //Clears the session
}
else
{
lblMsg.Text = "Click the calculate button first";
}
}
I am trying to enable show/hide password feature. I am creating an asp.net web form using C#.
My code is as below,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class show : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
if (CheckBox1.Checked == false)
{
TextBox1.TextMode = TextBoxMode.Password;
}
if (CheckBox1.Checked == true)
{
TextBox1.TextMode = TextBoxMode.SingleLine;
}
}
}
On mypage.aspx,
there is a checkbox whose autopostback property is true and a textbox whose textmode is password.
The expected result is:-
show password into text when checkbox is checked.
hide password when checkbox is unchecked.
The problem is :-
This code is working only once i.e. it is not being executed when checkbox is checked or unchecked again.
The textbox becomes blank.
Please help me soon.
You are losing value within TextBox because on selection change, the page loads again, you need to check whether its a postBack or first time load and set the textBox value.
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
string Password = TextBox1.Text;
TextBox1.Attributes.Add("value", Password);
}
}
Your problem will be solved. I've tested it.
Hope it helps!
There's exactly zero need to use a postback for this. An example using jQuery:
Markup:
<label>Password fields are just a UI convenience:</label>
<input type="password" id="password" value="super secret password" />
<label>
<input type="checkbox" id="toggle-password" /> Toggle
</label>
jQuery code:
$(function() {
$('#toggle-password').on('change', function(e) {
var _this = $(this);
if (_this.is(':checked')) {
$('#password').attr({
'type': 'text'
});
} else {
$('#password').attr({
'type': 'password'
});
}
})
});
A vanilla JS version:
var toggle = document.getElementById('toggle-password');
var textbox = document.getElementById('password');
toggle.addEventListener("click", function() {
var isChecked = toggle.checked;
if (isChecked) {
textbox.type = "text";
} else {
textbox.type = "password";
}
})
You can't set the text property of a Password Type field for security reasons.So another way to set the value after changing mode is
if (CheckBox1.Checked == false)
{
string pass = TextBox1.Text;
TextBox1.TextMode = TextBoxMode.Password;
TextBox1.Attributes.Add("value", pass);
}
if (CheckBox1.Checked)
{
TextBox1.TextMode = TextBoxMode.SingleLine;
}

Have you copied this method from other page/application ?
If yes then it will not work.
You need to delete the event and event name assigned to the button then go to design view and go to button event properties go to onClick event double click next to it, it will generate event and it automatically assigns event name to the button.
If No,
Try to Clean your solution and then try once again.
Please refer this article
Try changing the access modifier from protected to public, this will stop the method from being called depending on your class structure.
See here for more information on access modifiers: https://msdn.microsoft.com/en-us/library/ms173121.aspx
Try enabling the AutoPostBack property of the Button.
<asp:Button ID="btnUpdate" ValidationGroup="0" runat="server" CssClass="btn btn-warning" Text="Update" OnClick="btnUpdate_Click" AutoPostBack="true" />
I have set up a page with a submit button that the user can click and log in. I need to gather the field values and then do some backend stuff, but when the button is clicked, the even handler method I have set up doesn't fire. Heres the button code:
<asp:Button UseSubmitBehavior="false" CssClass="btn btn-primary" ID="btnTest" runat="server" Text="Submit" OnClick="btnTest_Click" />
And the codebehind:
public partial class SignIn : System.Web.UI.Page
{
protected void Page_Load(Object sender, EventArgs e)
{
btnTest.Click += new EventHandler(this.btnTest_Click);
}
protected void btnTest_Click(Object sender, EventArgs e)
{
string user = username.Value;
string pass = password.Value;
int userid = -1;
RoomSvc.Data.Person[] persons = RoomService.Service.ServiceClient.GetPersons();
RoomSvc.Data.Person pUser = null;
foreach (RoomSvc.Data.Person p in persons)
{
if (p.username == user && p.password == pass)
{
pUser = RoomService.Service.ServiceClient.GetPerson(userid.ToString());
}
else
{
return;
}
}
RoomService.Global.currentUser = pUser;
}
}
I have tried everything out there and nothing is making it work, could someone please enlighten.
EDIT: .aspx code:
<%# Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="SignIn.aspx.cs" Inherits="RoomService.Account.SignIn" %>
<asp:Content ID="SignInHeader" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="SignInContent" ContentPlaceHolderID="MainContent" runat="server">
<form action="SignIn.aspx" class="form-horizontal well span5 offset5">
<fieldset>
<legend>Sign In</legend>
<div class="control-group">
<label class="control-label" for="input01">Username</label>
<div class="controls">
<input runat="server" type="text" class="input-medium" id="username" />
</div>
</div>
<div class="control-group">
<label class="control-label" for="input01">Password</label>
<div class="controls">
<input runat="server" type="text" class="input-medium" id="password" />
</div>
</div>
<div class="form-actions">
<asp:Button CssClass="btn btn-primary" ID="btnTest" runat="server" Text="Submit" OnClick="btnTest_Click" />
</div>
</fieldset>
</form>
</asp:Content>
Your form tag is missing runat="server
I figured it out.
I had to add the even handler in Page_Init() not Page_Load()
