Hi all,
1. I have the Radgrid having updatable datasource (List<T>) that I store in the session's variable after updating/inserting.
2. All works OK excepting one thing:
3. Each time when I change the C# or aspx - add/remove some control, for example) first time after change the datasource extracted from session is null (when I want edit some row/insert new row)!
4, Second or more time (if I CHANGE NOTHING) all it's OK.
Can anybody give me prompt in this problem?
Thank you.
Boris

hi
maybe your session data is not add in the right event in session. anytime you change .aspx code your project compiles and session cleared.

Hi omi,
About which event you speak about RadGrid's event, or asp.net page event or some else?
Thank you

Hi omi,
the code is too big,
here I give the scenario when seswsion is lost:
1. start: Page load
if {!IsPostBack)
{
// get the data from database and save them in session
Session["data"]=DataFromDB
}
2. Initiating Postback (f.e. clicking the pencil on the grid's row)
RadGrid1_ItemDataBound(...)
{
// pseudocode:
If item is editable Item
{
data = Session["data"]
// HERE I getting empty session!
}
}
