In my project there are one video tag and two buttons. I am trying to do that when I click button1 then video starts playing and when I will click another button then another video starts playing. These two videos are in video folder inside my project.
here is the test.aspx file:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<link rel="stylesheet" href="css/test.css" media="all" />
</head>
<body>
<form id="form1" runat="server">
<div>
<video id="videoplr" width="500" controls="controls" runat="server"></video>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:Button ID="Button2" runat="server" Text="Button" OnClick="Button2_Click" />
</div>
</form>
</body>
</html>
Here is the code behind c# file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
videoplr.Attributes["src"] = "C:\\Users\\Punam\\Desktop\\Project\\videos\\personal_talk.MP4";
}
protected void Button2_Click(object sender, EventArgs e)
{
videoplr.Attributes["src"] = "C:\\Users\\Punam\\Desktop\\Project\\videos\\Tags.MP4";
}
}
When I am clicking buttons then video is not playing. I am new bie in asp.net.

Is there a way to use a session variable in CSS style such as to set width % dynamically.
width:<%Convert.ToString(Session["DaysAvailable"]);%>%;
Yes, as #JB11 confirmed. Here's a working example.
The div's width is set to 25% on PageLoad() only.
It's set to 75% on button Click() event.
SessionCSS.aspx
<%# Page Language="C#" AutoEventWireup="true" CodeFile="SessionCSS.aspx.cs" Inherits="SessionCSS" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<style>
.my-class{
background-color: green;
color: white;
width: <%= Session["DaysAvailable"].ToString() %>%;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div class="my-class">
Days available
</div>
<br/>
<asp:Button ID="btnUpdateDays" runat="server" Text="Update days" OnClick="btnUpdateDays_Click" />
</form>
</body>
</html>
SessionCSS.cs (code behind)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class SessionCSS : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if( !Page.IsPostBack)
{
Session["DaysAvailable"] = 25;
}
}
protected void btnUpdateDays_Click(object sender, EventArgs e)
{
Session["DaysAvailable"] = 75;
}
}
Result:
Note:This work only when CSS is directly inside the Page Markup and not in external Stylesheet.
I find a code for setting countdown timer but it only shows minutes not seconds when page is load and also I want that when user click on button then countdown should start and also time (e.g 10:59) should be shown on the clicked button.
Following is the code:
aspx code (ASP.net C#)
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Reservation.aspx.cs" Inherits="Reservation" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManagerTimer" runat="server"></asp:ScriptManager>
<asp:Timer ID="timer1" runat="server" Interval="1000" OnTick="timer1_tick"></asp:Timer>
<asp:UpdatePanel id="updPnl"
runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Button ID="btnTimer" runat="server" BackColor="#05CC00" Height="35px" Text="Reserve" Width="89px" style="border-radius:8px" OnClick="btnTimer_Click"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="timer1" EventName ="tick" />
</Triggers>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
aspx.cs code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Reservation : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!ScriptManagerTimer.IsInAsyncPostBack)
Session["timeout"] = DateTime.Now.AddMinutes(10).ToString();
}
protected void timer1_tick(object sender, EventArgs e)
{
if (0 > DateTime.Compare(DateTime.Now,
DateTime.Parse(Session["timeout"].ToString())))
{
btnTimer.Text = ((Int32)DateTime.Parse(Session["timeout"].
ToString()).Subtract(DateTime.Now).Minutes).ToString();
}
}
}
if (0 > DateTime.Compare(DateTime.Now,
DateTime.Parse(Session["timeout"].ToString())))
{
btnTimer.Text = ((Int32)DateTime.Parse(Session["timeout"].
ToString()).Subtract(DateTime.Now).Minutes).ToString("HH:mm:ss");
}
TimeSpan.ToString() offers a variety of string formats. More info : MSDN

I have an ASP.net WebForm. The markup is like:
<div>
<input type="text" id="input" runat="server" value=" " />
<asp:Button Text="send" OnClick="btnsend_Click" ID="btnsend" runat="server" />
</div>
This HTML is generated at runtime . The events are defined in the code behind file.
I need to add these controls at runtime. I tried to use the Literal-Control but the controls are working just like HTML Controls and not like ASP.net Controls.
EDIT:
Note: The Project type should be Website, not a web Application. Web application won't support on demand compilation where website yes, it is.
If I understood currectly, you want to take the Markup from User which contains even asp.net controls and scriplets too.
if this is the case, Follow below steps:
Create a dummy .ascx control file, like DynamicMarkup.ascx with empty content
Add this user control to the page (xxxx.aspx) where you want to show this control statically so it registered to the page
<%# Register src="~/DynamicMarkup.ascx"
tagname="DynamicMarkup" tagprefix="MyASP" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:PlaceHolder runat="server"
ID="DynamicMarkupContainer" ></asp:PlaceHolder>
</div>
</form>
</body>
</html>
Write user input markup (may be get from database based on your criteria) to the DynamicMarkup.ascx file in page OnInit of the page (xxxx.aspx) And the create object of this DynamicMarkup
DynamicMarkup dynamicMarkup = LoadControl("~/DynamicMarkup.ascx") as
DynamicMarkup;
DynamicMarkupContainer.Controls.Add(ucSimpleControl);
I have not tested this approach, Just give a thought, With this you may get some session overwriting issue which you need handle.
Hope this will help!!
OLD:
is this the one that you are expecting? TextBox, and Button controls are available in System.Web.UI.WebControls namespace.
void Page_Load(Object sender, EventArgs e)
{
TextBox input = new TextBox();
input.Id ="input";
this.PlaceHolder.Controls.Add(input);
Button btnSend=new Button();
btnSend.Id ="btnSend";
btnSend.Text="Send";
btnSend.Click += new EventHandler(btnSend_Click);
this.PlaceHolder.Controls.Add(btnSend);
}
void btnSend_Click(object sender, EventArgs e)
{
// throw new NotImplementedException();
}

<%=Eval(src) %> is not working.
<img id="Img1" src="<%=Eval( src) %>" runat="server" alt="" />
Code Behind
public partial class image_from_cb : System.Web.UI.Page
{
public string src="";
protected void Page_Load(object sender, EventArgs e)
{
src = "~/final.jpg";
}
}
I know i can do this with Attribute.Add or with ASPIMAGE , but i was just wondering why <% %> is not working
As You are using runat="server", You can use
protected void Page_Load(object sender, EventArgs e)
{
src = "~/final.jpg";
Img1.src = src;
}
Or if you want to use your src variable
<img id="Img1" src='<%= src >%' alt="" />
Try it
You can do this way
html
<img id="Img1" runat="server" alt="" />
C#
protected void Page_Load(object sender, EventArgs e)
{
Img1.src= "~/final.jpg";
}
And Another way is
try this Page.DataBind(); in Page load event
Look at my sample code html
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<img id="Img1" src="<%# src.ToString() %>" runat="server" alt="" />
<asp:Image runat="server" ID="myImage" ImageUrl="<%# src %>" />
</div>
</form>
</body>
</html>
and code behind
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebApplication1
{
public partial class WebForm1 : System.Web.UI.Page

public string src = "";
protected void Page_Load(object sender, EventArgs e)
{
src = "~/1455094_265560366930522_537876922_n.jpg";
//Add this
Page.DataBind();

Easy coding !!The both ways working in my side
I’m trying to integrate “jquery.mmenu” in a Visual Studio project.
It seems that “asp:Button” does not work inside a “mmenu nav “.
Nor a "asp:LinkButton" seems to fully perform.
Take the specific case of a login:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="test._default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script src="Scripts/jquery-2.1.4.min.js"></script>
<script src="Scripts/jquery-ui-1.11.4.min.js"></script>
<script src="Scripts/jquery.mmenu.min.all.js"></script>
<link href="Content/themes/base/all.css" rel="stylesheet" />
<link href="Content/themes/base/jquery.mmenu.all.css" rel="stylesheet" />
<title></title>
<script>
$(document).ready(function () {
$("#login").mmenu({
});
});
</script>
</head>
<body>
<div>
<form id="form1" runat="server">
Open login pannel<br />
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect" LoginText="login" LogoutText="logout" LogoutPageUrl="~/" /><br />
<nav id="login">
<div>
<asp:Label ID="UserNameLabel" runat="server">User:</asp:Label><br />
<asp:TextBox ID="UserNameTextBox" runat="server"></asp:TextBox><br />
<asp:Label ID="PasswordLabel" runat="server">Password:</asp:Label><br />
<asp:TextBox ID="PasswordTextBox" runat="server" TextMode="Password"></asp:TextBox><br />
<asp:Button ID="LoginButton" runat="server" ClientIDMode="Static" Text="Login Button" OnClick="LoginButton_Click" /><br />
<asp:LinkButton ID="LoginLinkButton" runat="server" ClientIDMode="Static" OnClick="LoginLinkButton_Click">Login LinkButton</asp:LinkButton>
</div>
</nav>
</form>
</div>
</body>
</html>
The code behind looks like:
using System;
using System.Web.Security;
namespace test
{
public partial class _default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void LoginButton_Click(object sender, EventArgs e)
{
if (Membership.ValidateUser(UserNameTextBox.Text, PasswordTextBox.Text))
{
FormsAuthentication.RedirectFromLoginPage(UserNameTextBox.Text, false);
}
}
protected void LoginLinkButton_Click(object sender, EventArgs e)
{
if (Membership.ValidateUser(UserNameTextBox.Text, PasswordTextBox.Text))
{
FormsAuthentication.RedirectFromLoginPage(UserNameTextBox.Text, false);
}
}
}
}
The asp:Button does not post back.
The asp:LinkButton does not login.
Is there a way to have it working?
Thanks.
Web forms most of the time change the name of the element and jquery needs the exact name to find your button. Add this property to your button and test again
ClientIDMode="Static"
The mmenu plugin grabs the NAV#login from the HTML and puts it back directly inside the BODY. Meaning, the input and button are no longer inside the FORM (and thus won't submit the form).
Basically, if you put the FORM inside the NAV#login all should work as expected.
