asp.net - Telerik RadGrid - How to disable sorting for a row? -


how sort telerik radgrid, except top 2 rows? tried implement on sortcommand event.

taken 2 tables, in first put top 2 rows , in second 1 have rows except top two. sort second table , merge both , load data on gridview.

var dtmanager = getgriddata(); // data load on grid  string sortorder = convert.tostring(session["sortorder"]);    var dtmanagertop2 = dtmanager.clone(); var dtmanagerexcepttop2 = dtmanager.clone(); (int rowindex = 0; rowindex < dtmanager.rows.count; rowindex++) {     if (rowindex < 2) {         dtmanagertop2.importrow(dtmanager.rows[rowindex]);     } else {         dtmanagerexcepttop2.importrow(dtmanager.rows[rowindex]);     } } var dvmanager = dtmanagerexcepttop2.defaultview; string sortby = sortbytext == string.empty ? "name" : sortbytext; dvmanager.sort = sortby + " " + sortorder; var dtnew = dvmanager.totable(); dtmanagertop2.merge(dtnew); dsgrid.datasource = dtmanagertop2;  if (convert.tostring(session["sortorder"]) == "desc") {     session["sortorder"] = "asc"; } else {     session["sortorder"] = "desc"; }

behind code:

grid.columns.findbyuniquename("type").sortexpression = string.empty;

or html:

<columns>     <tr:gridboundcolumn datafield="field"                         headertext="description"                          allowsorting="false" /> </columns>

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
