[Solved] Radgrid rendering freeze the browser

Hi,
I have a radigrid which i bind client side, it have max rows 100 and for every page i bind only the 100 items. I get the data with PageMethods. Everything worked fine until chrome latest update 26.0.1410.64 m after that when the radgrid gets the data the tab is freezing and the loader gif i have freeze. Also every time i change the page tha same freezing happend. The whole page performance is very slow.

The page in chrome when the radgrid paints the data is very slow and the waiting is for minities. I have tested with devtools and i saw that the freezing happed after the client side gets the data and try to databind. In IE 8 also freeze for a sorter time than chrome, this performance improved in IE10 and my page is a lot faster. In Firefox there is a tiny freeze only for a sec.

I have try to improve performance for the grid and for the page
http://www.telerik.com/products/aspnet-ajax/getting-started/top-performance.aspx
http://www.telerik.com/help/aspnet-ajax/grid-viewstate-reduction-techniques.html

but nothing. And everything happend after the latest update of chrome. In IE of course it always happend but our client does not used much. The telerik version i have is v.2012.2.815.35

RadGrid with OnItemCommand and ClientSettings-ClientEvents-OnCommand

Hello,

I have a RadGrid for which I use the OnItemCommand event. As expected, in the event handler I can find the GridDataItem from which the event was sent in the GridCommandEventArgs.Item.

Now I add a client side event handler for the event ClientSettings-ClientEvents-OnCommand. After this (javascript) event handler is called, a postback occurs and the server side OnItemCommand event is fired. But the GridCommandEventArgs.Item is now always referring to the first item in the grid and not the item that caused the event to be fired!

Am I doing something wrong?

Cheers,
Paul.

[Solved] Server Side Open with Animation

HI,

I'm not sure if there are other controls that might do this better than the panel but here goes....

I have a search panel. When the user has entered all the search parameters and clicked 'search' - I'd like the search panel to close "with animation" and the results panel to open "with animation". Obviously the search function needs to be processed on the server during this,
I've looked around and tried the ACT but no joy as yet.

All help appreciated.

Cheers,
