Hi,

We just ran in the same issue while replacing our Menu component for Telerik's menu. Everything works fine, as long as the page doesn't include a WebGrid or WebTextEditor, then we get stuck with a bunch of JavaScript errors.

I would like to know what hapenned with this issue, what was the conclusion? Was there any solution found for this?

Alexandre

Hi,

We cannot do what you suggest for many reason. One of the reason is that the datasource is manipulated in memory before being passed to the WebGrid. We cannot let the WebGrid hit directly the database in this case.

Our problem is related to a design flaw in the webgrid. A Collection is using an ArrayList which is exponetially non performant as it grow. We suggest that you use a different type of collection in order to improve globally the performance of your webgrid.

We also looked at the MSIL of WebGridColumnCollection.Add and found that a simple change could avoid making 90 000 IndexOf which should improve the performance.

In this method, you are doing the following in order to add a row only if it is not in the collection already:

if (this.indexOf(webGridColumn) == -1) then you add the row and set its .Collection property to this.

Instead of doing the indexOf you could only check if the collection is already equals to this, it would be way more efficient.

like this:

if(webGridColumn.Collection != this) then you add the row.

We are kind of stuck with this problem and we see that there are easy way to fix it. Can we make an arrangement in order to test that in a dirty build or something with you ?

Michel,

Les textes peuvents en effet être modifiés, ça fonctionne de la même manière que pour le WebGrid (via la propriété TextSettings du WebTextEditor). Par contre, ce n'est qu'une partie des textes qui peut être modifiés, il y en a plusieurs qui ne sont pas exposés (http://www.intersoftpt.com/Community/WebTextEditor/Many-texts-cannot-be-customized-translated/).

Et le contrôle a aussi plusieurs problèmes avec les version de IE8 et inférieures, s'il est configuré en mode HTML5 plutôt que Quirks.
