Hi.
I have radtreeview1 (CheckBoxes=true, CheckChildNodes=true, TriStateCheckBoxes=true) and I am filtering an OpenAccessLinqDataSource with this radtreeview1.SelectedValue.
But there are multiple selected value of radtreeview and this give me an error.
How can i filter to OpenAccessLinqDataSource with control.SelectedValue (multiple value).
Error is something like that : system.web.query.dynamic.parseexception: '==' operator incompatible with operand types 'int32?' and 'object' .
Thanks.

Hi,
In such scenarios instead of using the SelectedValue property we recommend using the NodeDataBound server event and check the appropriate node if it needs to be checked.
Hope this will help you solve the issue.

Hello,
In such cases you can retrieve all checked TreeNodes upon a postback to the server-side by using the CheckedNodes property, which returns an ArrayList collection of the TreeNodes that have been checked in the browser as it is described in this on-line demo.
