I need to upload an avatar to server in 3 steps using Ajax:
Choose file to upload.
Choose crop zone using jquery.Jcrop.js.
Create avatar and save it to DB.
I have created a user control to implement it. So user clicks the upload button and there is a modalPopUpExtender shows dialog box where users have to choose the file to upload (using AjaxToolKit File async uploader), after the file is uploaded the second PopUp extender has to show the uploaded image in another dialog box to let the user choose the rectangle to crop. And the last step (button click "Create") is to crop image and show it in the parent page. I'm successful with first step. But I can't make the uploaded image to be displayed in the second dialog box.
So here is my complete ascx file and its code behind:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="Avatar.ascx.cs" Inherits="KR.Trivital.Web.UI.Controls.Avatar" %>
<script type="text/javascript">
window.onload = function () { $addHandler($get('ctl00_CntAvatarBox_ImgButtAvatarImage'), 'click', showOverlay); }
function showOverlay() {
var bid = $find('mpeBehaviorID');
bid.show();
}
function uploadComplete(sender, args) {
var bid = $find('mpeBehaviorID');
bid.hide();
var bid2 = $find('ModalPopupExtender1BehaviorID');
bid2.show();
}
</script>

This is a "creative solution", but it does work.
It uses the AsyncFileUpload's OnClientUploadComplete you're already using and a Control on your page that will trigger an update on your UpdatePanel (e.g. a Button; can have display:false if you like).
function uploadComplete(sender, args) {
// Your code
__doPostBack('<%= UpdatePanelUpdatingControl.UniqueID %>', '');
}

I have an asp.net Button control which I want to use to insert comments in my page. When i click on button, I want it to call a method instead of submitting the form. How do i achieve this?
This is what i have tried so far -
<%# Page Language="C#" %>
<!DOCTYPE html>
<script runat="server">
protected void Button1_Click(object sender, EventArgs e)
{
//Do some stuff here
}
</script>
<head>title and other css links go here</head>
<body>
<form id="form1" runat="server" onsubmit="false">
//Some other asp.net controls go here
<asp:Button ID="Button1" runat="server" Text="Comment" OnClick="Button1_Click"/>
</form>
</body>
</html>
Is there any other way to achieve what I am doing? Suggestions are welcome.
I don't really know exactly what you are meaning.... I think you are asking for how to insert a comment into an aspx via a shout box???... Maybe?
Here is the code to insert whatever you want to type(a comment) into your form from a "method"... although it uses a lot more than just a single method.. this is the simplest way I can think of...
This is your default.aspx (notice no master page here)

And this is your C# Code
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
public partial class _Default : System.Web.UI.Page

}
public class ShoutItemList
{
private List<ShoutItem> shoutList = new List<ShoutItem>();
private void Purge()
{
DateTime purgeTime = DateTime.Now;
purgeTime = purgeTime.AddMinutes(-3);
int i = 0;
while (i < shoutList.Count)
{
if (shoutList[i].Timestamp <= purgeTime) shoutList.RemoveAt(i);
else i += 1;
}
}
public void Add(ShoutItem shout)
{
Purge();
System.Threading.Thread.Sleep(2000);
shoutList.Insert(0, shout);
}
public string Display()
{
Purge();
StringBuilder shoutBoxText = new StringBuilder();
if (shoutList.Count > 0)
{
shoutBoxText.AppendLine("<dl>");
foreach (ShoutItem shout in shoutList)
{
shoutBoxText.Append("<dt>" + shout.UserName + " (");
shoutBoxText.Append(shout.Timestamp.ToShortTimeString() + ")</dt>");
shoutBoxText.AppendLine("<dd>" + shout.Comment + "</dd>");
}
shoutBoxText.AppendLine("</dl>");
}
return shoutBoxText.ToString();
}
}
This will allow you to insert whatever comment you want. You can modify this code to your own please....
Let me know if this is the answer you seek.
Use the button's OnClientClick, like this:
<asp:Button ID="Button1" runat="server" Text="Comment" OnClientClick="return javascriptFunction();" OnClick="Button1_Click"/>
then your javascript function would look like this
function javascriptFunction() {
//do something here
return false; //if you don't want the form to POST to the server, leave this as false, otherwise true will let it continue with the POST
}
I am working on a simple asp.net login page. Yesterday, the code was working fine. Today, it isn't.
The only thing that changed between yesterday and today is that I shut down my pc and started it again today.
The problem is that Page_Load is firing twice (I checked all the answers/solutions, and none worked (image with empty src, handling the page_load manually, setting autoEventWireUp to false...)) none of these seemed to do the trick.
PLEASE can someone help me figure out why this is happening?

}
}
Likely the webpage is really loaded twice. Check your javascripts (or any AJAX components?), or use the browser's debug console to monitor the network requests being sent. Try adding empty methods on the PreInit, PostInit (etc.) events and set breakpoints too, I bet those are hit twice as well.
before I begin, there is another question with a similar title and it is unsolved but my situation is pretty different since I am using Ajax.
I recently added a label to my Ajax UpdateProgress control and for some reason my asp.net page is not reading it. My original goal was for the text of the label to be constantly be updating while the long method runs. I am using code behind, and I believe the label is declared. I will post my .cs page if anyone would like to read through it (its not too long), All my other labels work perfectly and even if I take the label OUT of the ajax control it will work fine (not the text updates though). Is there a certain Ajax label I need to use?
Im pretty confused why the error is occurring. The exact error message states : "The name 'lblProgress' does not exist in the current context. Im using c#, ajax controls, a asp.net page, and visual studio. This program uploads a file to a client and stores the information in a database. If anyone can help I would really appreciate it. Thanks in advance!

If the Label is created inside the UpdateProgress control, then you will need to do something like this
((Label)upUpdateProgress.FindControl("lblProgress")).Text = "Uploading File...";
If the control is declared in markup and the code-behind doesn't recognize it, then your designer.cs file is probably out of sync. There are a few ways to fix this:
Close the form and reopen it, and remove and add lblProgress again
Add the Label to the designer.cs file manually
Here's how to add it manually:
/// <summary>
/// lblProgress control.
/// </summary>
/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
/// </remarks>
protected global::System.Web.UI.WebControls.Label lblProgress;
EDIT
Just noticed that you're putting the UpdatePanel in an UpdateProgress control, in which case you'll need to reference it using FindControl (like #Valeklosse) suggested.

Thanks!!!!
I'll go ahead and tell you with almost 100% certainty that the line that is causing this is:
var targetFolder = Server.MapPath(Commons.PAGER.UPLOAD_FOLDER);
It could be that you do not have permission to connect the server, or a variety of other issues.
To test this change "var targetFolder" to something like:
var targetFolder = #"C:\Users\j\Desktop\TEMP\"
Run this and it works perfectly, hence the idea that the path you're trying to access on the server is the problem.
Perhaps you should specify the path if possible. For example, if you are on a domain:
var targetFolder = #"\\server\Users\"
This would access that server and then the users folder therein that I have on my domain.
First I have to let you know that i am a newbie in this area, learning from tutorials.
With that said I'm looking for a way to load sourcecode from the codebehind file into a textbox, when clicking a button. Same goes for the aspx file.
Im making this website, where i am going to show code examples from what im doing. So if I navigate to myweb.com/tutorial1done.aspx this page would show me the final result from the tutorial done. When i click the show source button it should make 2 textboxes visible, and add the codebehind to the first box, and the aspx source to the second box.
I don't know if it is possible, but I am hoping so.
This far i have this:

And the Codebehind:
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 DateTimeOutput : System.Web.UI.Page
{
protected void output(String value)
{
outputText.Text += value + Environment.NewLine;
}
protected void runButton_Click(object sender, EventArgs e)
{
DateTime dt = new DateTime();
output(dt.ToString());
DateTime nowDt = DateTime.Now;
output(nowDt.ToString());
}
protected void clearButton_Click(object sender, EventArgs e)
{
outputText.Text = "";
}
protected void dt_showSource_btn_Click(object sender, EventArgs e)
{
if (dtcb_output.Visible == false)
{
dtLabel1.Visible = true;
dtcb_output.Visible = true;
}
else
{
dtLabel1.Visible = false;
dtcb_output.Visible = false;
}
if (dtaspx_output.Visible == false)
{
dtLabel2.Visible = true;
dtaspx_output.Visible = true;
}
else
{
dtLabel2.Visible = false;
dtaspx_output.Visible = false;
}
}
}
}
For now source highlighting is not needed, unless its easy to do.
Thx in advance.
If you're refering to the actual code of your code behind file, you have a problem. As the file will be compiled and then be placed as intermediate code in a dynamic link library (.dll), you don't have access to the .aspx.cs file any more. The only way to go would be to include the code behind file with the deployd project and open it with a FileStream (or whatever) to read it and display it's content.
