I'm writing how best to expand the root node of the TreeView control by default, on the page load - either with C# or with the properties of the RadTreeView;

rootNode.Expanded = true  - this code did not work as expected;

I'm trying to use the list box in a load on demand scenario, but I have a need to set it's height via javascript rather than on the server object. Is there any way to get load on demand to work in this scenarios?

Thanks,

I have an issue on how to save the layout of all RadDock controls on a web page when a RadDock is moved to a new location. Currently, I have server side code that saves the users layout position to the database. However, the user must click a command button to save layout. However, the user wants the application to save the new layout when a RadDock is closed or moved to a new location. Is this possible.

Hi Telerik,

I had a requirement of doing like Quickbook Grid (Screens attached).

Please advice me in doing this .

Hello,
 I am facing a problem using RadFilterDateFieldEditor . Sometimes there is rendering problem in IE 6, 7, 8 browsers.
Have you got any idea why it happens?

Dear TelerikTeam,

I am using RadGrid.There are list of rows displaying in it, but I would like to select (or) highlight the newly inserted row. So that the new user can easily identify the row which is inserted.

Note: I am also using paging for your reference.

-Thanks

Hi,

I using some ampersand characters in my treeview, but when I validate my page with http://validator.w3.org I get some error on the ambersand characters.

Line 146, Column 132: StartTag: invalid element name

…x?Category=$VingepumpeMindre250&amp;menyCategory=1,1">Vingepumper, <250 bar</a>

Is it possible to make the treeview control to show ambersand?

when i try to bind the Grid view using the Pagemathods or webmethods, everything works well and its fast.
but the above is true only if my web method returns not more than 20 rows of data.
as soon the webmethod returns more than 20 rows, the RadGrid control simply doesnt bind or refresh, as if no action was made !?
at first i thought that it might be just slow so i tried waiting for more than 30min and the result is the same...

if i do the same thing but bind the grid on server side using the NeedDataSource event then it loads more than 20 rows, but because the performance is much faster on client side binding, i need to make it work on client side.

using the visual studio 2010 debugger i followed step by step and a strange thing happens the ajax call to the webmethod is beingsent ok, and the pagemethod / webmethod is executed ok and returns the data, once the data is returned to radgrid its like it swallows it and no further action happens nor any other client side events are fired or javascript code is executed...

Please help, i spent almost a week on this issue and cant find a solution... many thanks in advance...

please see below the grid code and pagemethods that i am using:
