View 3 RepliesI have a ListView control that is inside of an update panel. I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button. The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected. I then can go to another page, come back and the new data is there. I'm not sure what I missing. Please see the code below.

I have an application that allows users to insert data into a log. The forms are displayed inside update panels and display via modalPopUpExtenders. I am running into a problem where users are able to click the Insert button multiple times before the panel can update that a click was registered.
How can I disable the Insert button once the user clicked on it and had time to communicate with the server? The system is allowing duplicate and triplicates to be inserted into the system.
I try to clearn asp.net form on cancel button click using String.Empty but it does not seem to be working. Here's my aspx code:

am using a radiobutton list. In the selection change event i am doing some fuctionswhile i selecting repeatedly. It throws the javascript error.
View 2 RepliesI have update panel in which i have a label and a textbox and a button
I havwe a Radiobutton list which i am using In the asynchoronous postback trigger of the update panel.
In the Control Id of the trigger I have passed Radiobutton List Id and in the event name I am passing SelectedIndexChanged
But when I click the button no event is firing rest all is working fine.
I have this download button, which is inside the update panel. due to the post back issues, the download button is not working and the whole page posts back. is there any way to remove that button alone from the hold of the update panel and make everything else work under update panel.
View 2 RepliesI have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?
If the gridview and print button are inside the update panel,then the print fuction is not calling.
If i place the print button outside the update panel then it is working fine.
I tried this link to generate verification Image [URL] ..... It works fine.
But I'd like to put a button in page for regenerating captcha for example. When the image was unreadable for user.
So I put an updatepanel in page and this is my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<tr> <td colspan="2">
<asp:Image ID="imCaptcha" ImageUrl="~/Captcha.ashx" runat="server" />
[Code] .....
Although the image changes but the whole page is refreshed. Whether this is due to incompatibilities httphandler and updatepanel?

I am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section
1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient
bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User
will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also
2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station details
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.
Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button
Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?
Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.
But when I am clicking on imagebutton it is closing the modalpoup.
And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.

I have this label that i want to fadeOut after button event clicked. I am using a MasterPage. And the Script Manager is declared on MasterPage. In Defaulst.aspx i have:
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlaceHolder" runat="Server">
<script type="text/javascript" src="scripts/jquery-1.4.1.min.js">
$(function () {
$("input[id$='btnShowDate']").click(function () {
$("span[id$='lblStatus']").fadeOut("slow");
});
});
</script>
<asp:UpdatePanel runat="server" ID="uP">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnShowDate" />
</Triggers>
<ContentTemplate>
<asp:Label runat="server" ID="lblStatus" />
<div>
<asp:Button runat="server" ID="btnShowDate" Text="Show Today`s Date" OnClick="btnShowDate_Click" /></div>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
And on the CodeBehind i have:
protected void btnShowDate_Click(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(3000);
lblStatus.Text = DateTime.Now.Date;
}
The problem is that the label is not fading Out after the button clicked. Does someone has any idea on how to handle this problem?
I have a TabContainer with multiple Tabs. For some of the Tab's Button OnClick events work and on others they do not. I have dropdowns etc in each of these tabs and their SelectedIndex events fire. Just some of the button events don't fire. If I move the HTML and codebehind to a blank page for any of the Panels that don't work, the buttons work as expected.
View 7 RepliesI have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
[URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button
clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.
I have a radio button list and it is populating data from database.
I want to show a modal popup extender when someone clicks a specific value in the radio button list.
For example:
display the modal popup when radiobuttonlist.value=="13".
I have one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
