c# - Update dynamically column header within Repeater -

-

i want update text of column header based on type of object. let's have objecta , objectb; if objecta want appear in second column "a version". if not objecta (meaning objectb) update same column " b version" text.

i have in .aspx file:

<asp:repeater runat="server" id="rptbillheaders" onitemdatabound="rptbillheaders_itemdatabound">     <headertemplate>         <table width="98%" align="center" class="grid" cellpadding="0" cellspacing="0" style="border:solid 1px #000000; border-top:none 0px #ffffff;">                 <tr class="gridheaderrow">                     <th>&nbsp</th>                     <th><asp:label runat="server" id="billversionlabel" ></asp:label></th>                     <th>action type</th>                     <th>doc # </th>                     <th>status</th>                     <th>total amount</th>                     <th>developed by</th>                     <th>date submitted</th>                     <th>date processed</th>   ...

in code-behind have:

protected void rptbillheaders_itemdatabound(object sender, repeateritemeventargs e) {     repeateritem item = e.item;     if (item.itemtype == listitemtype.item || item.itemtype == listitemtype.alternatingitem)     {         repeater rptlineitems = ((repeater)item.findcontrol("rptlineitems"));         rptlineitems.datasource = currentbill.lineitemsbyobjversion[rownumber].sort(billlineitem.sortcolumn.lineitemnumber, system.data.sqlclient.sortorder.ascending);         rptlineitems.databind();         rownumber++;     }                control headertemplate = rptbillheaders.controls[0].controls[0];         label billversionlabel = headertemplate.findcontrol("billversionlabel") label;         if (lit.billtypes.obja == "a")         {             billversionlabel.text = " version";         }         else if (lit.billtypes.objb == "b")         {             billversionlabel.text = " b version";         }  }

it might easy do, i'm learning asp.net. therefore, researched on how developed , has tutorial 1 tried implement in solution.

so far no changes appears in when run web application.
