hi my dear friends :
i have a radcombobox that is in relationship with RadListViw (with RadDataPager Inside)...
when i change the item of rad combobox , so RadListView is Updated... -> selectedIndexxhanged() server-side event...
-------------------------------------------------------------------------------------------------------------------------------------------------------------
my selectedIndexChanged() is like this :
my radComboBox Item values is like : 1,2,3...
in mode 1 we have 25 pages...
in mode 2 we have 5 pages...
in mode 3 we have 5 pages...
my problem is when we are in mode 1 and put the pageNumber to more than 5 and when i change the combobox Item to mode 2 so
but if we put the page# (we are in mode 1) to lower than 5 or equal 5 , and change the radcb item to another everything works fine...
where is the null problem?
thanks for advance
