AJAX :: How To Do Update Panel And Dynamic Controls And Post Back
Sep 29, 2010 I have a page that is mostly dynamically built in the page load of my VB.net code behind page.
The issue is that I made a change to the page and added a button that redirects to a secondary page. When the button is clicked there is a very noticeable lag until the button click event fires because the page is being rebuilt every time.
I had not wrapped the code in the load event in the If not ispostback.... because I have dynamic controls that the user interacts with and I need the page to be rebuilt when the user clicks them.
The dynamic controls are clickable table cells. I did some looking and I found that the RegisterPostBackControl. I thought this would be perfect but, it does not although I maybe using it incorrectly.
Here is the code flow.

AJAX :: Update Panel Post Back To Show Processing
May 11, 2010I have a page that the users get redirected to. On page load this page runs a bunch of code behind that and loads table. The processing could take a few seconds to minutes depending on how big a report is run. Is there any way to completely render the page before automaticly kicking off the code? I am trying to stay away from forcing the user to click on another button.

Web Forms :: Scroll Back To Drop Down List After Auto Post Back In Code Behind?
Feb 22, 2011Using Vb.Net 2003 Asp.Net 1.1
I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

View 1 RepliesAJAX :: Dynamic Image Buttons In GridView Not Doing Partial Post Back?
Sep 9, 2010watch here:
- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

View 1 RepliesAJAX :: Using Browser Back To Previous Page Containing Gridview Inside Update Panel?
Aug 6, 2010Looking for the best technique on handling or at least some documentation showing an example.
Starting Page
Gridview control withing an update panel (also various controls used for filtering NOT IN UPDATE PANEL)
Databinding does not happen during page load.
Databinding is initiated when update panel trigger (asp:Button object) is clicked
Hyperlink column is added to returned records
Hyperlink posts to a separate page for detail for record which the hyperlink was clicked.
Second Page
While navigating via the browser back button to previous page (which contained the update panel and gridview) only the (various controls used for filtering) have retained state. The gridview is not shown (which is how the page loads initially when starting) How can I retain the state of the Gridview and add a step in the browser history all together?
AJAX :: Using DropDownList To Do Update, Autopost Back Required?
May 22, 2010I have a script that I am trying to trigger an AJAX AsyncPostBack and have been trying to figure out how to get it to work. After searching the internet for a while I noticed something on all the examples. On the asp:DropDownList they use the autopoastback=true tag. If I add it to my script it works fine, if I remove it it stops working. So my question is why is the autopostback required or if it is not what might I be missing? BTY Everything is in C# and .Net 4

Web Forms :: Cascading Drop Box Holds Old Value If Empty On Auto Post Back?
Sep 3, 2010I have 3 drop boxes: 1.) Choose Operation 2.) Choose Site 3.) Choose Area. All three of them are linked to an SQL server database which has 3 tables following the same heiarchy of order. I.e. Areas belong to a Site and Sites belong to an operation. And there can only be one operation per site, or one site per area.
First you select an operation, then the page auto postbacks to filter the sites. Then you pick a site and again it autopostbacks to filter the areas. The issue I am having is that when an associated operation has no sites underneight it, and therefore no areas under that, the previous values that were in the boxes are displayed and the user can't click on the boxes anymore. I think this is kind of cheap looking and would like a way to make it so the boxes are clear (i.e. nothin in them). Is there anyway to check if they are going to freeze like that and assign them blank values?
