asp.net - Pagination not working in asp:DataGrid -

-

problem:

when attempt go page 2 or other subsequent page of data grid, nothing refresh page.

markup:

<!--main datagrid--> <asp:datagrid         id="dgtasks"         runat="server"         pagesize="40"         allowpaging="true"         autogeneratecolumns="false"         forecolor="#333333"         gridlines="both"         font-size="small"         allowsorting="true"         onitemdatabound="item_databound" >         <headerstyle             backcolor="#990000"             font-bold="true"             forecolor="white"             horizontalalign="center"             font-size="small"/>          <columns>             ...         </columns>         <selecteditemstyle             backcolor="#ffcc66"             font-bold="true"             forecolor="navy" />         <pagerstyle             backcolor="#cccccc"             forecolor="#333333"             horizontalalign="right"             mode="numericpages" />          <alternatingitemstyle             backcolor="white" />          <itemstyle             backcolor="#fffbd6"             forecolor="#333333" />          <footerstyle             backcolor="#990000"             font-bold="true"             forecolor="white" /> </asp:datagrid>

code behind:

public sub page_load(byval sender object, byval e system.eventargs) handles me.load     if ispostback         'donothing'     else         binddata("")     end if end sub  private sub binddata(byval strdisplaycompleted string, byval strsort string)     dim taskdataset taskdataset = new taskdataset()     dim dt datatable = taskdataset.getdata("n").tables(0)     each dr datarow in dt.rows         if dr.item(2).tostring().startswith("vacancy")             dr.delete()         end if     next      if strsort.length > 0         dt.defaultview.sort = strsort     end if     dgtasks.datasource = dt.defaultview     dgtasks.databind() end sub  private sub binddata(byval strsort string)     binddata("n", strsort) end sub

now, i'm not close sure why pagination not working. have allowpaging equal true, i'm not re-binding data on postback, i'm confused. great. thanks.

it doesn't appear binding datagrid control objectdatasource, entitydatasource automatically take care of paging you.

you need handle paging event gridview , reset page index yourself

i.e.

gridview.pageindex = e.newpageindex

(i not @ machine ide cant confirm syntactically correct right now)

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
