I'm working on a simple demo project so that I can learn some things about ASP.NET's AJAX capabilities. My problem is that I can't seem to get an UpdatePanel to work properly with a CheckBox inside of it. Here is the markup I'm using in my .aspx file:
[Code].....
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
I have a simple Textbox for entering password and the checkbox named Show passowrd beside it. Textbox mode is Password by default. These controls are in the table and I am using Update panel on top of the table. My application framework is 2.0 and I am Using ASP.NET 2.0 AJAX Extensions.
Now When i write some text in the textbox and check the Showpassword chekbox then the checkbox event is not getting fired. when Second time i click it then the event is fired and text in the textbox is removed and the textbox mode is set to the SingleLine. This functionality I am achieving by writing a code in the CS File.
When I remove the Update panel then the event is fired correctly everytime, but when usign Update panel and some text in the textbox then i have to check the checkbox twice for the desired functionality.
I have one button on my page. On click of this I need to run four methods parallely in four saperate thead and need to show the progress bar for each method. Also need to update the label controls form those threaded methods.
Also I need to user Update panel of AJAX control tool kit to avoid post back to user.
I have used the read pool for that. When I remove the update panel the code works fine and update four labels but when I put the update panel it is not updating the labels.
Hopefully someone can give me some pointers to get this working properly.
I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
i have written the foolwong code to show/hide the panels but it is not working properly can any one tell why..
private void button1_Click(object sender, EventArgs e)
{
panel1.Visible = true; [code]....
But only for first button it is working properly...
I am having a problem with partial postback through update panel, Update panel is not working properly in my asp.net app with IE8. But app works fine if i switch to compatibility mode of IE8.

It was recommended to us jQuery to resolve some of the issues that I am having. I have been trying to incorporate jQuery but it is not functioning properly. First I have a template:
Code:
<html xmlns="[URL]
<head id="head1" runat="server">
<title>Inventory Management</title>
<link href="Inventory.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="jquery.js"></script>
<asp:contentplaceholder id="phjQuery" runat="server" />
</head>
<body id="masterbody">
<form id="form1" runat="server">
<asp:ScriptManager ID="smInventory" runat="server"></asp:ScriptManager>
<div style="text-align:center;">
<table style="width:100%" border="0" cellpadding="2" cellspacing="0">
<tr>
<td class="xxlargeBold" colspan="3">
Inventory & Order Management<br />
<hr />
</td>
</tr>.............

I'm writing an app in which user can register. While registering the one may choose several options and according to these regiester fields are visible or not and are required or not. I came up with an idea that all fields will be in in the updatePanel and when users changes registration options I would set visibility of these fields on the server side.
It works but incredibly slow and whats more on the FF I have the given error:
The state information is invalid for this page and might be corrupted
3 checkboxes with other fields are in the updatePanel
Each field is in dl tag with runat="server>
I had to do it like that cause for "required" option I simply add css class to this dl (need in in javascript validation. If field should be visible I set visible="false" for given dl and then that field for example FirstName with title and so on isn visible after postback.
Am I doing something wrong ? Why does it take so long (~4 min on localhost) and in firefox it doesnt really work (when I use debug I think that process completes without errors on ff, I dont understand that at all :)
If update Panel is so weak what would be other option to change visibility and adding required class to all dls. Logic is quite complicated and has to make query to DB so simple javascript would be quite tricky.
Oh and I'm using ASP.Net and cant upgrade on this project.

This code works fine if i use this inside ssercontrol > panel and i have a checkboxes in table when no checkbox is checked its works fine .... but if i disabled and checked any of the textbox then this doesn't work .... in usercontrol why ? i didnt understand ..
<script type="text/javascript" language="javascript">
function checkboxChecked(){
var allInputs = document.getElementsByTagName("input");
for(var i=0; i<allInputs.length; i++) {
var chk = allInputs[i];
if(chk.type == "checkbox" && !chk.disabled && chk.checked) {
return true;
}
}
alert("OOps! You haven't selected all available checkboxes");
return false;

I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.
In the template field i am creating a dynamic javascript on RowDataBound.
I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.
I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.
fileupload control is inside a grid, When Ajax is not used its s working correctly, so as wen i use a Update panel, am getting a error in uploading my file to thr database.
View 4 RepliesI am facing a problem in FileUpload controls that is available inside update panel along with CalendarExtender.
Now When I click on submit button after browse a file it is returning null fileobject value in codebehind page.
[Code]....
I dont know what is the reason behind of this problem, can you let me know what is the cause and probable solution for this.
I am using JQuery tabs in my aspx page, but update panel is not working. If I do any operation in tab2, after posting back, tab1 is activated.
