c# - Setting an ItemTemplate property in RunTime -

-

i trying display small progress bar in gridview within asp.net application. trying itemtemplate.

                            <itemtemplate>                                 <table width="100%">                                     <tr>                                         <td style="width: 75%; background-color: red"></td>                                         <td style="width: 25%; background-color: green" ></td>                                     </tr>                                 </table>                             </itemtemplate>

i want set width percentage based on calculation of values within row.

can done somehow eval? or need code behind?

you can try following approach (sample calculation below):

<td style='<%# string.format("width: {0}%; background-color: red", (int)eval("width") / 100) %>'></td>

but readability sake should better move whole string construction code behind , call corresponding method on page.

update. code behind approach, here how can done. define method appropriate calculations , return string:

protected string getcellstyle(int width) {     return string.format("width: {0}%; background-color: red", width / 100); }

and call same data binding syntax:

<td style='<%# getcellstyle((int)eval("width")) %>'></td>
