asp.net - JavaScript code for fetching list of items into a GridView -


i have asp.net web application. on page_load grid view items created. have <asp:textbox> , search button. using pagemethods rid of postback. idea when button clicked call javascript function , call webmethod. webmethod returns list of items based on searched criteria.

how can fetch these items , populate gridview them?

in other words partial update - on button click supposed update gridview.

here code webmethod:

[webmethod]     public static list<item> searchresults(string text)     {         itemfunctions item_functions = new itemfunctions();         list<item> items = new list<item>();         items = item_functions.searchresults(text);         return items;     }

and here gridview, button , textbox:

<asp:scriptmanager id="scriptmanager1" runat="server" enablepagemethods="true" /> <asp:textbox id="search_textbox" runat="server" />         <input type="button" id="button1" value="search" onclick="searchresults();" />         <div id="searchresults_gridview" >             <asp:gridview id="gridview1" allowpaging="true" gridlines="both" runat="server" allowsorting="true"             autogeneratecolumns="false"             width="740px"             causesvalidation="false">             <columns>                 <asp:boundfield datafield="item_name" headertext="item_name" />                 <asp:boundfield datafield="item_description" headertext="item_description" />                 <asp:boundfield datafield="item_quantity" headertext="item_quantity" />                 <asp:boundfield datafield="category_name" headertext="category_name" />                 <asp:boundfield datafield="type_name" headertext="type_name" />                 <asp:boundfield datafield="item_available" headertext="item_available" />                 <asp:boundfield datafield="item_serial_number" headertext="item_serial_number" />                 <asp:boundfield datafield="item_permission_status" headertext="item_permission_status" />                 <asp:boundfield datafield="item_location" headertext="item_location" />                 <asp:commandfield showselectbutton="true" selecttext="view" />             </columns>         </asp:gridview>         </div>

this searchresults functions called on button click:

<script>     function searchresults() {         pagemethods.searchresults(onsucceeded, onfailed);     }      function onsucceeded(result, usercontext, methodname) {     }      function onfailed(error, usercontext, methodname) {         alert("an error occured :(");     } </script>

my javascript skills bad , still learning, otherwise in theory think rest of code should work.

you can in javascript, @ point require dump gridview's html (because after gridview has rendered html) , re-create html table. while may preferred solution lose data on full postback , required re-run javascript.

you using updatepanel functionality. see following links on using updatepanels :

how use updatepanel in asp.net without refreshing page?

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
