Bind Column data based on previously populated rows

Hi,

Could you please help me with this scenario.

I am binding a radgrid with primary event data (eventid, locationid, centerid, date) from a list1 and sorting it using SortExpression. if a certain criteria is met i need to check the date of the (sorted) first row and find the nearest secondary event date from list2 and add the comuln (template column) during runtime.

Please note the page is still not loaded, How do i access the sorted list that will be shown on UI? How do i populate the template column with data?

EditCommandColumn command argument?

I'm trying to get a list to populate in an edit form when the user clicks "edit" but the GridEditCommandColumn doesn't have a "CommandArgument" property. What would be the best way to work around that?

Checkboxes in grid

Hello I have a grid as below with the 2 columns that are second to last having checkboxes that are supposed to be clickable when the person who's record is displayed is accessing the page...

however when that person does not have the canDelete permission (from on PreRender below) clicking these check boxes throws a client side error..

'Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Can't select a disabled or unselectable menu item.' when calling method: [nsIDOMEventListener::handleEvent]

edit: just as a note even without that prerender code i still get the same error..

also one more thing the rad grid is in an UpdatePanel

i guess its important to note that when all the checkboxes are editable it works fine... when only some are enabled it breaks

Any ideas?
