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.

Rendering Dynamic Controls Via JavaScript In A Wizard In An Update Panel?

Mar 3, 2011

I have a user control.

On that user control is an update panel.

In that update panel is a wizard.

One of the steps is as follows.


What this does is create a javascript spinner control. Now when I click the NEXT button onto this step it generates the spinner control. I click next to go to the next step, then I click PREVIOUS to go back to this step and the spinner control is not generated.

Now I have tested this on an ASPX page and it seems to work, I then copy the code across to an ASCX control and put the page live and it does not work.

The update panel has an animation extender that just displays a div with a processing gif when you click next/previous.

So any reason why it creates the control on the next and not the previous step?

Dynamic JavaScript Not Working In Update Panel?

Apr 20, 2010

I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.

In the template field i am creating a dynamic javascript on RowDataBound.

I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.

I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.

AJAX :: Multiview Dynamic Control Disappear Into A Update Panel?

Jan 12, 2010

I have a page with an UpdatePanel in wich I load the menu selected Layout pages, and the layouts loads its contents dynamically.

It works fine, but when I load a Layout that has an Multiview control, the code behind of the Layout don't come in into the if(!Page.IsPostBack), ok, I fixed it with if(multiview.ActiveViewIndex==-1) multiview.setactiveview("viewName").

In the Multiview I have a ListView, in the listview I have Linkbuttons that opens another view and shows the information of the specified row dynamically.

when I click in the link so the page disappear from the update panel... why? I do not a full postback of the page, so I think I don't need to reload that page on the update panel... Right?

AJAX :: Update Panel Versus Dynamic Populate Extender

Dec 20, 2010

I have an invoice form that I want to be able to populate using an ajax control. There will be a section at the top that will allow the user to select a record from a db or create a new one. This section will have several criteria types that can be used to select the records. They will be able to choose the record by the invoice id, date of service....etc.

I'm trying to decide between using the dynamic populate extender and the update panel for the different areas of the invoice. For example, there are different sections that show the customer's info, notes for the invoice, the services performed and the totals for the work done. I want each of these to be dynamic. For example, when a new service is added to the invoice the total is updated. Or if an existing invoice is opened these fields will be populated for that record.

I'm trying to decide if the dynamic populate extender or update panels should be used for each of these dynamic sections of the invoice. It seems like either can be used but I'm not sure which would be better.

AJAX :: Update Panel And Update Progress Controls?

Aug 31, 2010

I have written a Crystal reports web application, that prompts ths user for parameters and then apply them and exports the report to a folder as .rpt and then display the report.

I prompt the parameters on one screen and then display the report on another page. I have the AJAX update panel and update progress controls in the parameter page. When the user enters the parameters and click on ok, I export the report and then loads the report to a session report document and transfer the user to the second page where the report is displayed. I use the following code to do transfer to the seconds page.

I have excluded the report load and parameter assign code here.


In the second page I have the following:

rptViewer.reportsource = Session("rpt")

My problem is this works one time and then stops working the second. What I found out was it comes to the statement:


But it does not even load the show.aspx page. It stays on the parameter page. There are no errors displayed. I could not see any errors when I debug the application also. And out of the blue it works sometimes. And if I remove the update panel and progress control, my report works all the time.
