For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?
i'm just getting started with asp.net and ajax. My question is : is it possible to make an ajax request and simulate the server response in the code behind. in other words can the request be sent to the code behind of the same page? if it's possible haw can i perform this ?
View 2 RepliesI use four different update panels, that use the same timer as trigger.
1) Will the 4 update panels create 4 different HTTP requests to the server?
2) I'm using 4 different panels as the controls are located in different parts of the page, is there a way of putting them in the same update panel?
3) Is this a good coding practice?
As far as I understand UpdatePanels, they should be invalidated separately, i.e. triggerring one UpdatePanel should not touch the controls of the other panel. It does work so for controls outside of any UpdatePanels, however those which are inside ANY UpdatePanel are touched by triggering ANY UpdatePanel:
<form id="form1" runat="server">
<asp:ScriptManager ID="SM1" runat="server"/>
<div>

When the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?
View 2 RepliesI'm looking for a way to use custom ASP.NET validators to validate input, without using UpdatePanels, and without a full postback. The validators do several things - not just length/regex, but some other non-standard stuff as well. Javascript is required for our users, so I don't have to worry about normal users who have javascript turned off. I see several options, but none are ideal:
1) Suck it up and use UpdatePanels. I'm in the "UpdatePanels are evil" group, so I'd prefer not to do this.
2) Without using validation controls, manually validate the fields by passing the values to a PageMethod static method, via jQuery or any other AJAX framework. This would require client and server coding each time I needed to use a validator.
3) Use jQuery (or any other javascript framework) validation for client validation, then if they somehow get by that, have server-code validation controls for full postback. This would require all of the validation rules to be written in javascript as well as C#. I don't care about the full failed postback at this point, because the javascript validation would catch real users who weren't trying to screw me over.
Is there alternative out there for using real CustomValidator controls, with partial postback, C# code only, for validating input without UpdatePanels and without a lot of redundant javascript?
I have a page with 5 buttons on top. I want the area below the buttons to contain an update panel that will display button 1's panel if they click button 1. If they click on Button 2, then I want button 2's update panel to replace the button 1 update panel. Each panel has stuff on it like check boxes and text boxes.
Is there a way to do this? Is there a more efficient way to do this?
i have 3 update panels on the same page with labels that are showing different countdown and i want then to run separate from each other. I've tried to use timer control that triggers each of them separatley with limitations in ontick event., the coutdowns are strating but after a few seconds are stoping and i don't know why.i'm not using scripts. I want to run like those on mafia wars on Facebook when something is done to start one contdown and something else other timer.
View 3 RepliesI realise that there are many posts on update panels and repeaters but none that quite solve my problem. I have a page with two Repeaters each inside seperate update panels. They sit next to each other one on the left and one on the right. The left repeater is filled from my database on my page load event. Im am storing the data in a List<> and then binding the list to the repeater. This works correctly and displays all my results. Each item in the left repeat has a button aswell. The button needs toremove the data from the left repeater and place it in the right repeater. I only want the database to be accessed in the Page_Load and then never again during the use of the page, until the data is saved (I have not got to this feature yet). So I have decided to use List<> objects.
View 6 RepliesI'm using two update panels, and in the Page_Load, I'm calling if (masterPageScriptManager.IsInAsyncPostBack).Is there a way to test where the update came from and only refresh the affected panel?
View 1 RepliesI have a page that display a record set inside an update panel. There are also a handfull of checkboxes/textboxes that allow filters to be placed. Each checkbox/textbox is set as an async trigger for the update panel and set to autopostback.
If a single checkbox is clicked the whole filter/render process takes roughly 1.5s.
If I check a filter and then several more before the intial postback is complete I get a postback time of somewhere between 20-50s depending how many boxes I've clicked.
I notice (via firebug) when I check a box that triggers an async postback and than another box the original async post back is aborted. And yet it seems like it still executes (or maybe locks?) something on the server.
I have multiple update panels on a page. The page works perfectly in Chrome, Firefox, safari, and opera but it does not work in IE. I am using .NET 4.0.
View 1 Repliesi have 4 update panels, and 1 of them updates after a button has been clicked, and the other 3 panels contain other buttons, but what i would like to do is that, when the button is clicked, how would i make it ONLY trigger for that update panel, as it updates the whole page, and is affecting my Textbox on the page, which is also in an update panel. how i could make just that specific panel update, and not all of them?
View 2 RepliesSuddenly all update panels in my website became unknown elements. They work fine when I run site.
But:
no intellisense in update panel (no properties appear, no tags, like "triggers")
no ID property when I drag updatepanel from toolbox
VS says that I check if webconfig contains reference to System.Web.Extensions
But I have this reference already.
I have 3 updatepanels on my page and I want 2 of them to update when an event is fired. In one of the update panels I have an asp ReoderList.

View 4 RepliesI have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.
View 2 RepliesI have two different repeater control which are in two different Update panel.I want to bind one Repeater value with another.But When i am using asyncPostBackTrigger or postbacktrigger it is reloading whole page.
I want to load only load update panel
I am going to outline my setup then where i am failing
UpdatePanel1 - Contents : 3 textboxes and AddButton
UpdatePanel2 - Contents : 1 GridView and SubmitButton
AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page

I'm using the standard way for send HttpWebRequest
[Code]....
As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.
Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.
