asp.net - Webmatrix - WebGrid: change css style conditionally -


i've started webmatrix , i'm trying transform html table webgrid. data comes db , want change css class each td (within 1 column) depending on items content.

so example if item contains "," apply class="multi", if doesn't contain "," , not null class="single", else "none". 

<td class="multi"> <td class="single"> <td class="none">

i've tried webgrid style: , format: settings couldn't classname switch depending on value of item. think need right syntax started.

i hope can me out here. thank you.

if want use webgrid, real option set td style based on cell value via javascript after has rendered. style parameter accept string representing css class apply.

alternatively, can conditionally set content in format parameter based on value, filling td span or div can style eg:

<style>     td.nopadding{padding: 0;margin: 0;}     .green{background-color:green;display: inline-block;width: 100%;height: 100%;}     .yellow{background-color:yellow;display: inline-block;width: 100%;height: 100%;} </style> <div id="grid">     @grid.gethtml(             tablestyle : "table",         alternatingrowstyle : "alternate",         headerstyle : "header",         columns: grid.columns(             grid.column("country", style: "nopadding", format: @<text>@html.raw(item.country == "usa" ?                                                                   "<span class=\"green\">" + item.country +"</span>" :                                                                   "<span class=\"yellow\">" + item.country +"</span>")</text>))     ) </div>

update: following code illustrates more complex if..else statement being accommodated in format parameter:

format: @<text>@if(item.yourproperty == null){                   @html.raw("<span class=\"none\">" + some_value +"</span>")                   }                   else{                     if(item.yourproperty.contains(",")){                          @html.raw("<span class=\"multi\">" + some_value +"</span>")                     }                     else{                         @html.raw("<span class=\"single\">" + some_value +"</span>")                     }                }                </text>

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
