I have a master page that has a usercontrol on the left side of the page with a dropdown. When the user selects a value from the dropdown I need to load a different aspx page. The new page has a similar (but not the same) looking usercontrol on the left and different content on the right. How can I do this? Also, when the new page is loaded the dropdown must remember its selection.
View 2 RepliesI have alot of code in the page load event as below.
Is it best practice to use (!NotPostBack) and wrap the code in this block or does it depend on the methods etc. I also have code which populates ajax slideshow as well which gets images from database.

I'm creating user controls that i will put into an update panel and make them visible only when required using triggers. Once visible it will float in a dialog box so it has a close button which will just hide the control on client side.
The controls have multiple post back states, like a wizard, i'm using a multi view control to accomplish that. My problem is that once the user is at step number two in the control, if the user closes the dialog, than opens the dialog again, (note that the control is made visible on the server and reloaded by updating the updatepanel) the second step will still be displayed. The reason is . because whenever there is a postback the control will load its state using the viewstate, even if EnableViewState is false it will still load it using the LoadControlState method. so my quesion is how can i force a user control to load fresh with its default values without any postback data.
I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2
Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I hv Declared two Master page one Is Base and Derived.. Base Page Load is working but when i hv written load controls in Derived Page Load Using C# it's not working..

View 3 RepliesWhen an asynchronous postback happened inside update panel, another postback happens also for MasterPage not only update panel embedded page .
I want to prevent this MasterPage postback .
is this possible ? think like i have a MasterPage
and another page which is test.aspx which is content page of MasterPage
i have update panel at test.aspx
when asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Load
i want to prevent this (it should not also load MasterPage Page_Load)
we are creating a custom content management and out portal page is bit bulky it is about 60Kb without images.
and during loading the page in some browser we can see some parts of site load faster than the other parts of the site where as we want to indicate (or instruct the web server) to load some of the areas first then load rest of the page.
is there any particular setting in IIS for is there any particular method in classic asp for doing that?
also I have the same question in asp.net.
I'm developing my first Facebook application in ASP.NET 2.0 and doing a simplest thing, that is, to show a navigation on top with four hyperlinks where each link targets to another .aspx page. How can I do this using FBML in ASP.NET 2.0?
Otherwise coming to my question, where I'm struck after trying above thing at myself and failed then had to go around the Ajax way of doing this. Now I'm using Ajax call over the onclick event of each hyperlink from top navigation and it's succesfully loading external .aspx pages (for example,[URL]. The problem is when user comes on the application on first time, it only shows the .aspx page which has a navigation and a Ajax content place holder which is programmed to be filled with contents on click event.
How to load Ajax contents into the Ajax content place holder on page load without a click event?
how i can load an panel(that contain for example Weather information) after page load
View 2 RepliesI am using a third party gateway. The third party gateway does not support query-string , so i will need to post the form to pass the values to the given URL and another thing is that they don't expose the web-services so we need to use their page and that means we need to host it in an iframe in asp.net
so what i did is that i have hidden fields that will be used as parameters as depicted below
Code:
<input type="hidden" name="p1" value='4635' />
<input type="hidden" name="p2" value='Reference_test' />
<input type="hidden" name="p3" value='Purchase credits' />
[Code]..
Now the purpose of this , is to load the iframe after the page load event of the asp.net gets fired.
Now my problem here is that when the iframe loads , it does not pass the parameters to the url that is being set in the iframe.
I have attached the example, project. (2kb)
When you run the project you will notice when the iframe loads there is an Error
"NO VCS ID"
now this means that the parameters were not passed when the Iframe loads , i can understand because it seems like iframe does not do a full form post. so to demonstrate what i want, click the proceed button and you will notice it will give you a page with no errors and it will be a page where credit card details are required , i want to iframe to load that the first time.

I have a situation where I need to have close to 30 drop down lists on one form. The user also wants the autocomplete functionality. I decided to use the ASP.NET AJAX control. So that the page will load faster I hide them until they are needed. But, as more and more become visible the postback time is getting longer and longer.
I know this can be fixed, but I'm not sure how. Can anyone give me any advice, point me to some articles? Do you have a suggestion for another method of doing what I need? Maybe, I shouldn't even be using ComboBoxes for this?
iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.

And I got very limited reference about the uframe(codeflex,codeProject).
In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.
While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.
Is there any way to load controls without postback?
