Ajax Update Some Part After Loading The Rest Of The Webpage?
Feb 12, 2011
A portion of my site requires data from a web service, with takes 7-8 seconds. How can I load the rest of the website, show a Updateprogress for the data which comes from the service, than show the data once obtained trough a updatepannel. Some working project would be great.I need the server to retun the page before the data from service is obtained, and add that data later using ajax
I use only some controls from the AjaxControlToolkit (eg. Tabs and ModalPopupExtender), and I would like to be able to reference/load only those parts from the DLL.
I have update panel on the page to avoid postback and placed a dropdownlist control within that update panel. DrodownList is filled with Category names and also it's autopostback set to True.
Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.
I have a requirement like need multiple update panel in web page and also i want to load only one (targeted one) update panel content when I click button on another update panel.
Got some small(Basic) doubt on update panel. Using Update Panel, Is it possible to stop updating a part of Page ?
The problem is, I have a very small portion of page, in which I'm updating some data using JavaScript, Which I want to retain(in ASP language Maintain State) for any post back that will occur in Page. I thought placing update panel will solve the purpose, But as per Update panel principle, It will updates only that part of page based on the Triggers conditions.
I want it exactly in reverse way (It is very difficult for me to place Update panel for the entire page excluding the small part).
The above throws this error: CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments
I've got a working update panel which works fine when updating a label control, but I can't get it to work with an updated image (initial image loads fine - the problem is with the update). I think the problem maybe that the image name and location don't change, only the physical file. In other words, I've loaded the page, then updated the image (same name and location), but the image does not update with the label? Here's my code:
I am using a master page which has a table that is used for layout. In one of the cells I have a Accordion control which holds links in each panel to navigate to the various pages. I have a few pages that take some time to load so I was trying to use the update panel progress control, however it seems that you cannot use a hyperlink or a link button as triggers for the update panel or if you can you cannot if it is in an accordion control.
So I am seeking advice on how to show a loading message when the pages load in the content panes.
my application is running in visual studio 2005, i used ajax control toolkit for .Net framework 2.0.but now i want to use ajaxcontroltoolkit latest version which is for .net framework 3.5 in my application which is running on .net framework 2.0 and visual studio 2005.how to integrate or use ajaxcontrol toolkit ?because i have some functionality like there is one file upload control and when click button it will take 2 to 3 min for upload so i need progress bar with loading gif file.because of asynchronous postback fileupload control has not file.so i must assign postback trigger to button if i assign postback trigger to button than loading gif or progress bar not working.so i want to use AsynchFileUpload control of newly release toolkit.
is there any way to do it? or any other way.my client also not want to switch over it's application from 2005 to 2008.My code is below
I want to build a business object such as an employee class, but I know that 80% of the properties will barely get used. So I wanted to know how I can create the object with the important properties in the constructor and lazy load the ones that are barley used when they are needed (if at all).
I have looked at nearly every single WCF Rest PUT/POST issues on SO here and have still been unable to determine why I am unable to PUT or POST to my web service but am able to call a test GetTime method via GET. This particular service exchanges custom credential information (username, password and some other information) for a token. This token information is encrypted and added to the header of subsequent requests to other web services so that username/passwords don't have to be passed around everywhere. All web service calls are still treated as stateless, but require this auth header information rather username/passwords to access secured service operations.

I have also checked in IIS 7 the handler mappings for *.svc and checked that 'all verbs' are enabled.
I am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.
why it doesn't render the control properly and what can I do to fix it?
I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.
I have a web page that has lots of different parts to it (i.e many data grids). The page takes quite a while to load up because it is running all the stored procedures to populate each grid so the user is left waiting for the whole page to load.
I would like to improve this by loading the page a section at a time so that to the user is not left waiting for the whole page to load up before anythin can be viewed.
What is the best way to tackle this problem. Do i need to use threading or would i being going down the wrong path looking into that.
I have a panel bar..each time I press panel bar item I display ascx control with in update panel..but it lakes update panel loading time lot..how I can decrease that loading time?
if I have a data grid on my web page along many other controls, and that datagrid is fetching some data while the page loading.

I ma trying to load a usercontrol into a table. My usercontrol contains some literal controls.

i am using Master Pages for my site(VS-2005). A page in my site gives user information about a city which he has selected from a drop down list. I want that when a user selects a city's name from a drop down list control, then a particular HTML file of that city should get loaded into that page. The ASP.NET page should remain same but only loaded file should change. If a user has chosen London then the HTML file of London should be loaded, if the selection is Paris then XML file of Paris should be loaded in the same Page. How can I do that ?

Not sure how to solve this problem so thought I would ask here, as always.Scenario:I have a page where you can add a book review. But for each book, you can have multiple authors from the list available in the database.To add a new author for a book, you post to a separate action. when you do this, this page refreshes, shows all the authors you have added for this book, but loses the information in the other form fields.
If I posted the authors using Ajax, they would be added to my list, and my form controls would be fine, but then the part of the page that displays the authors currently added would not be updated to show the new author.I'm thinking maybe I can make the added authors a partial view and when I post the new author asyn I could somehow tell that part of the page to update.
