Asp.net - Make Update Panel Not Update Whole Page?

Oct 16, 2011

I have an update panel that has a table in it with 4 images. Every few seconds a new image is shown. All this works but when the image changes the whole page is refreshed. I am using Visual Studio 2008 and VB.Net 3.5.I only want the images in the updatepanel to refresh. How can I do that?

UpdatePanel Code:
<asp:UpdatePanel runat="server" ID="upImgSwitch" UpdateMode="Always">
<ContentTemplate>
<table height="200px" width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>

Make Current Tab Page Update When New Data Is Loaded?

Mar 31, 2010

I'm working on a VB.Net windows application.In the top half of the form application, I have a vendor number with a "GO" button and in the bottom half I have a list of tab pages. We have built the application to only go to the database and display data when the tab page is selected by the user. If I'm in one of the tab pages, and I change the vendor number and click the GO button, the data on the current tab page goes blank (it does not refresh). I have been told that I have to find a way of programmatically clicking on the tab page's tab a second time. How do I do that? I've tried using _Selected event, _Selecting event, _Click event. I've even tried to do a .Focus() on the tab page itself. Nothing seems to work to reload the new data without clicking off of the tab and back onto it manually.

.net - Why Does ASP ListBox Take So Long To Render In AJAX Update Panel

Dec 3, 2009

I have a problem when updating the source of an ASP ListBox in an AJAX update panel. When I set the source of the ListBox to a large dataset, I would assume it would take a small amount of time to render due to the number of items. However, when the DataSource is switched at run-time to a smaller set of items, it takes just as long to clear it. If you go from a small set of items to a small set of items this is lightning fast. Maybe I'm doing something wrong. I'm using the Visual Studio 2008 item template for an AJAX 1.0-Enabled ASP.NET 2.0 Web Application. I downloaded that from Microsoft.

Here is my code (Full source zip below):

List Getting Cleared Every Button Click Inside Update Panel?

Apr 22, 2010

url...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.

I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

Update A Master Page From A View?

Sep 10, 2010

I have an ASP.NET MVC 2 project that renders conventional strongly typed pages, but on some of these pages I also want to use the page's object to render a specific area (div) in the navigation section of the Master Page.

For example, if I have a Client object and associated strongly typed View, I want the View to be able to insert client-specific navigation items within a div in the Master Page's navigation.

I've actually achieved this in a not very elegant fashion by creating a ViewData item to hold the Client object - this is in addition to returning the client object with the View. The Master Page then takes the ViewData object and, if it's not null, renders the client-specific navigation section. This way of doing things will get very ugly as the number of different objects that have to be handled increases.

Javascript - Update Page After GridView DataBind?

Sep 27, 2011

Apparently, part of the problem is that while an ASP:GridView has an OnDataBound() event (which you can use in the code-behind), the corresponding HTML table that is produced does NOT, so you can attach that event to JavaScript. (Did I get that right?) So, that's why I'm having trouble with that bit of the issue. Back to the drawing board. I'm a desktop developer (WinForms with VB.NET) transitioning into ASP.NET development. My mind is really bending around the DOM and JavaScript and Session State and all of the stuff that goes along with web development. I'm not stupid, and I've done research (including hours of video watching and hundreds of pages of "Intro to ASP.NET" reading), but I keep hitting the wall with what seem to be fairly straightforward problems.

Basically, my current situation can be summed up as follows:

I have a page that runs a very long process initiated by the user. The long process can take up to a few minutes , so I want to indicate to the user that SOMETHING is happening.When the process has completed, I either have:

a. Results to show in a GridView

b. No results to show

If I have results to show, I want to display them. If I have no results to show, I want to show a label to the user that says "No results to show."

Asp.net - Updatepanel Doesn�t Update Correctly - Must Click Twice To Update
