View 1 RepliesI am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?

View 3 RepliesWe have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?
I am facing a critical condition wherein I have a web page and a User control within it.I need to set the value of two labels in the user control using values collected on the server side.However whatever I do on the server side or client side I do see on the webpage although I can see in the code that it is being set.So Now I am just sending the value from the server side and setting it on the client side.I am sending from server side using,

Related to my previous question which is answered. The deal is, there is an update panel for modalpopup extender that is triggered by a button. The problem is when the form is submitted by a button, this modal popup is seen on the page! I do NOT want this modal popup extender to be seen when the form is submitted.

I have a page on which there is a textbox that is in update panel and has text changed event and autopostback=true. On the same page there is a 'Retrieve' button(inside repeater control) outside the updatepanel. Now what is happening is if user inputs data in the textbox and clicks retreive button page_load event is firing twice which is not what should be happening, one time its the partial postback due to the text changed event and second time is the page post back. I would like to restrict the second postback.

i am using the update panel in my application in that i had added 3 dropdownlists,all of them are having the selectedIndexchange event so, once you select any item in the dropdown list i had to some operation, but the problem is that if i change the any dropdownlist in the update panel all the dropdownlists selected index methods are getting called, but what i was expecting is that when i select any item in first dropdonwlist that corresponding selectindex has to be executed not the other ones, so anybody had experienced this kind of problem let me know?
View 3 RepliesI am having an issue with an update panel, which is still causing the entire page to postback.
I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.
I am using a master page, but the update panel only appears in the content page, within the content tags.

want to do a page refresh when a button inside an update panel is clicked. Is it possible and how?
View 7 RepliesIn one of my webpage, I have a parent window where i have a datalist with 10 rows of images. when i click any image a pop up window(child window) opens.
The child window has a form to be filled by user. Once user fills this form, he will press the save button. Once the save button is clicked, the child window should be closed and the datalist(in the update panel) in the parent window should be refreshed.
This is how I am trying to achieve this. On click of the save button a javascript function is being called of the parent window like this: window.opener.refreshDataList();
in the refreshDataList() function I have written the following code:
{
childWindow.close();
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
This works like a charm in Internet Explorer. However in Mozilla and Chrome it doesnt work. While testing this I added an alert statement ind the refreshDataList() function like this..
{
childWindow.close();
alert("Testing");
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
Once I added the alert statement, It started working in both mozilla and chrome.
So I realize that It could be an issue related to focus. I have done window.focus()
but still its not recieving any focus and not working in Mozilla and Chrome.
add new row in gridview programmatically without postback (using update panel)?
View 7 RepliesI've got a page that posts back constantly and if im on the inputbox thats instide the update panel i loose focus on postback
how would i get it to recognise that im on the textbox in the update panel and keep focus on it.
Below is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.
-- aspx page
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
It works fine in Firefox but in IE 7 fails doing the postback sometimes. Is it just a problem with my browser? The partial postback inside the update panel works great in both browsers, but when I hit the button outside the panel, the complete postback doesn;t work in IE....
