[CLOSED] Loading UserControls with UserControlLoader --Version Ext.NET.MVC.Pro.2.1.1

Hello,

I have in my application a few speed issues.
At Page (View),I load at runtime several instances of a UserControl( .ascx with UserControlLoader)in
my Panel.

One can imagine the UserControl as a contribution to a profile in Facebook. This UserControl has many functions.
I have the opportunity to build this client side. This also works well.

But the problem is, for many controls will my contribution-container(panel) slowly.
For example,the insert a text box in this panel by jscript takes an eternity until it sees
and the browser has rendered finish...

Have you any ideas for a solution to this problem ??

Thanks for helping!

Hi @ontiv,

Please demonstrate how you add a test box.

Hi Daniil,

but that was just an example of many...
.js

Code:

---

var AddPanel = function () {

            var p_addpanel = new Ext.Panel({
                height: 100
            });

            Ext.getCmp('p_contributionlist').add(p_addpanel);
        }

---

All actions are influencing the content of the panel are slowly.

Examples:
-The height of an UserControls is changing...
-I delete a UserControl
-I add a panel
-I show or hide an UserControl or an another element

I hope you know what I mean :)

That does not happen when I add just a lot of panels (ext:Panel) on the client side. I think
it has to do with the UserControlLoader and UserControls..

Thanks

Could you test it with the Ext.NET sources from SVN trunk?

There were some improvements regarding this part.

The structure of my view is similar to this guestbook here :

Attachment 5569

Can you give me some hints to build a chronologicial list like your guestbook (or any other blog).

I need a container that gives me a lot of possibilities to design my own items (UserControls)
and in the same time the best performance as possible (to handle big data, lazy loading, loading by scrolling, paging).

ASP.NET Repeater, Ext.NET DataView or XRender mechanism can be an option.

It is hard to say what would be the best option.

Maybe, the option that you currently use is not bad. Please provide a sample to reproduce the problem, we would be happy to try to improve the performance.

loading by scrolling

If you mean infinite scrolling in GridPanel, then it is only available for grids and trees (> v2.1).

I mean "loading by scrolling" like this http://www.aspsnippets.com/demos/288/

The build of different templates or usercontrols and display them in one container

Thanks for clarification.

There is no ready solution for this, but it all should be possible.

I have already noticed that the DataView is very fast, but is there a way to add the templates dynamically to DataView ?
because the problem is that I have several items..

Another question...Can I build the template from DataView with Ext.Net controls ? or only asp ?

Thanks

Well, a DataView now supports Ext.NET controls (very recent enhancement), but it is not recommended to use for rendering many complex items.

Maybe, for your case XRender is better.
