html

<div id="ucprodres-any-mfg">         <asp:repeater id="rptanymfg" runat="server" >             <itemtemplate>                 <div id="ucprodres-any-mfg-row">                     <div class="ucprodres-stock manufacturer">                         <div class="ucprodres-mfg ">                             <div id="ucprodres-exp-any-mfg" data-swap="-">+</div>                             <div>&nbsp;&nbsp;<%#databinder.eval(container.dataitem, "mfg")%></div>                         </div>                     </div>                     <div class="ucprodres-stock qty-avail">                         <%#databinder.eval(container.dataitem, "qty")%>                     </div>                     <div class="ucprodres-stock availability">                         <%#databinder.eval(container.dataitem, "availability")%>                     </div>                     <div class="ucprodres-stock unit-price">                         <%#databinder.eval(container.dataitem, "qtyrange")%>                     </div>                     <div class="ucprodres-stock dollar">                         <%#databinder.eval(container.dataitem, "qtyrangeprice")%>                     </div>                     <div id="txtboxid" class="ucprodres-stock qty-required" >                         <asp:textbox id="tbxanymfg" runat="server" style="text-align: right"                             tooltip="quantity should not more available quantity."></asp:textbox>                         <div class="ucprodres-txtbox-info">quantity should not more available quantity</div>                     </div>                 </div>             </itemtemplate>         </asp:repeater>     </div>

behind code

public sub button_click(sender object, e eventargs) handles button.click each rptitems repeateritem in rptanymfg.items         if (rptitems.itemtype = listitemtype.item) or (rptitems.itemtype = listitemtype.alternatingitem)             dim tbxqtyreqd textbox = rptitems.findcontrol("tbxanymfg")             if not string.isnullorempty(tbxqtyreqd.text)                 if tbxqtyreqd.text > "0"                     dim mfg string = rptitems.dataitem("mfg").tostring                     dim qty string = rptitems.dataitem("qty").tostring                     dim avail string = rptitems.dataitem("availability").tostring                     dim qtyrange string = rptitems.dataitem("qtyrange").tostring                     dim unitprice string = rptitems.dataitem("qtyrangeprice").tostring                     dim qtyreqd string = tbxqtyreqd.text                     dim rfqpart new parts.instock                     dim rfqpartdetails new parts.instock.partsdata(mfg, qty, avail, qtyrange, unitprice, qtyreqd)                     rfqpart.add(rfqpartdetails)                 end if             end if         end if     next end sub

i'm not @ vb syntax put sample in c# , can convert vb yourself.

first of need make sure bind repeater control once on page postback make sure have code on page_load method:

    protected void page_load(object sender, eventargs e)     {         if (!ispostback)            bindrepeater();     }       void bindrepeater()     {         rptanymfg.datasource = getdatafromdb();         rptanymfg.databind();     }

then on button_click event check the textbox control before unboxing textbox control below:

    protected void button1_click(object sender, eventargs e)     {         foreach (repeateritem item in rptanymfg.items)         {             if (item.itemtype == listitemtype.item || item.itemtype == listitemtype.alternatingitem)             {                 if ((textbox)item.findcontrol("tbxanymfg") != null &&                      !string.isnullorempty(((textbox)item.findcontrol("tbxanymfg")).text))                 {                     int value;                     string text = ((textbox)item.findcontrol("tbxanymfg")).text;                      if (!string.isnullorempty(text) && int.tryparse(text, out value))                     {                         if (value > 0)                         {                             // value assignments here                         }                     }                 }             }         }     }

just improve code it's if check textbox value integer before compare in if statement.

let me know if having trouble use code.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
