I am using SQL server R2(Version 10.50.1720.0). I have multiple-Multiselect cascaded parameters, Cascading is working fine in fetching and populating the next dropdown. If i change one of the child dropdown selection and then change the parent selection, child selection is not getting reset. Let me explain it further with following example. Country -> State are the multi select dropdowns. Initially i will have all countries selected -> So all States selected. Now let me Un Select 'Select all' option from Country and select US. Now 50 US states are selected. Now if i go back to countries and Select 'Select ALL', it doesnt refresh the States selection. Now it will display all states but will still have only 50 States selected. I have mapped the selected values the the same data set. Some one please suggest me how i can resolve this. itsgPhere
