Web Forms :: Hide Divs On The Initial Load And Make Them Appear On A Postback Event?
Dec 1, 2010I have several divs on an asp page. All of my divs are runat="server". On the initial load of my page I set all the divs visible property to false because I dont want them to appear on the first show. Then, I have a drop down list raising postback events.
On the selected index changed event I am setting the visible property of my divs to true to make them appear on the page. However this does not work.
I discovered that, on the initial load non of my divs are added to the page's html content. So, on a postback event non existing divs can not be made to appear. If all the divs would set to visible = true on the initial load, postback event would work just expected.
Could any one tell me a way to hide divs on the initial load and make them appear on a postback event?
Web Forms :: Dynamically Load UserControl, Access Properties In Parent Page Without Recreating In PostBack
Nov 15, 2010I 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

Aug 19, 2010I 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.

AJAX :: ComboBox Load Slow On Postback?
Feb 23, 2011I 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?

How To Load A Page With Its Default Values After A Postback
May 14, 2010I'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.

Jquery - Postback In Chrome Preventing Image Load?
Feb 25, 2011I'm doing a postback to generate a chart. When the user clicks the button it is using jQuery to add some html to the page to show an animated gif and an overlay.
This works fine in IE and FF but in Chrome the image doesn't load. Anybody know what's going on here?
While looking into the problem I noticed that if I run this code in the JavaScript console it works, and it will work as expected after running it in the console (displays image on postback).
Here is the code I'm using to add the html:
$("body")
.append("<div class='ui-widget-overlay working'></div>")
.append("<div class='ProcessMessage working'><img alt='Loading' src='images/indicator_big.gif' /><br /><br />Loading...</div>");

View 3 RepliesAJAX :: Generated Image Does Not Update On Postback Page Load?
Jan 26, 2010I 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?
