Any suggestion on how I would access all the rows in the radgrid, not just the rows on page #1? I tried:
RadGrid1.MasterTableView.Items.Count
This gives me 10 rows because that is how many are listed per page but I need to get at the datatable source. The user has a search form that generates the grid. After the grid I have a button to save the search results to another table. When they click the button though I can't access the datatable because it is generated in the RadGrid1_NeedDataSource method.
If I can't write the contents of the datatable to my sql table then I am just going to write it when the search happens regardless of whether the user wants to save it or not and then when they click save I'll set a flag on the table. Hope this makes some sense, any suggestions appreciated...

Hello DC,
A possible approach would be to disable the grid paging, temporarily, retrieve all the rows and then enable paging back again. This approach could be achieved by setting the RadGrid.AllowPaging property to false at a certain stage (for example RadGrid.PreRender event) of the life cycle and rebind the control invoking its Rebind() method, then traverse all items in it.
I hope this helps.
Sincerely yours,

Dear Radoslav,
I have the same problem.
I think this solution time consuming (I use the page property to avoid to load all the record and now I have to load all !)
Probably best solution is to attach directly to the ado/linq connection of the grid.

Hi RRE,
There are two ways to get all the rows to which you are binding the grid and I am agree with you that to turn directly to the database and retrieve all rows count through data access operations is the best solution.
The other way is to set AllowPaging=false for the MasterTableView of the grid, rebind (Rebind()) the grid, retrieve the Items collection, set AllowPaging back to true and again rebind the grid, in this case if the RadGrid has a lot of rows the performance will be decreased.
Kind regards,
