    I have been having a funny problem with one of my pages if I use the RadSessionPageStateCompression adaptor. 

    My page has a 2 grids and 3 combox boxes the user selects from the combo box and hits apply to get grid data, they can then click a grid row whcih calls a js function passing a value back through the xhttp panel to get data for a detail grid. the population method for the detail grid access the combo boxes as does the needdatasource for the primary grid.  everything works as it should for about the first 10 items the user selects from the master grid but on the 11th (not exactly) click the server can no longer see the selected items collection of the combo 'null'.

    If i then change to the RadHiddenFieldPageStateCompression adaptor everything works

    any suggestions?

    Hello Paul,

    I suspect that this beahvior may be related to the "history cache" of MS's SessionPageStatePersister class, used internally by RadCompression state adapter. Therefore can you please try modifing the historySize attribute value (in the webconfig) to a more appropriate value.
