extjs - How to remove checkbox selection from all views in checkbox selection model in EXT grid -


i have ext grid checkbox selection model. grid contains multiple pages of 50 records each. have 'clear selections' button deselect selected rows in selection model. code :

 handler: function(){          this.selectionmodel.deselectall();          this.selectedreordsarray.clear();           },         scope:

the problem is, when select records in first page , move second page , select records there well. if click 'clear selections' button deselects rows on page i.e. second page , when go page 1 , rows there still selected. there way remove checkbox selections pages.

thanks,

ps : using ext js 4.1.3

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
