Selecting and deselecting no working as normal

Hi,

I use same sample as found in demo webside and have some troubles.
If i select the header checkbox items are correctly selected. If deselect this checkbox no action is performed in selected items.
I can't use the suggested ItemCreatedEvent lauching the ItemPreRender because in this case when select, only my last item is selected no others and deselecting from header checkbox is not working.

Using PDF Functionality Without the Grid

Hi guys,

Is there a way to create PDFs on the fly using Telerik's APIs - not necessarily from a grid but by building the layout in code?

Rather than purchase a separate PDF component, I thought I'd check if there's a way to get at the functionality within the RadGrid.

Any tips, source code, or pointers are welcome.

Thanks,

Ken

BUG - Custom Validation in particular situation

Hello,
I would just notify a bug. It occurs in this situation: you use customvalidator in a radcombobox that has AllowCustomText="true". The client function associated to customvalidator is fired only when the radcombobox losts the focus, not when you click on submit button. If you set AllowCustomText="false" all works as espected (so the function is fired when radcombobox losts focus AND when you submit the page).

Bye

Independent submenu colors

Can the submenu colors be set to different colors based on the parent menu item selected. In the example below we would like to be able to have a blue background color for the submenu of the 1st menu item, a red background for the submenu of the 2nd item, etc... We are using a slightly modified version of the default 2006 skin. It would be nice if there was a groupsettings-cssclass property.
