c# - How To Access One UserControl from Another Using ASP.NET -

-

i have created user control uservote has property find total vote on particular question.

now want call aspx page.

the control code-behind (uservote.ascx.cs) looks like:

public partial class uservote : system.web.ui.usercontrol {     protected void page_load(object sender, eventargs e)     {         datatable dtvoteinfo = showvotedetail(objecttype, objectid);         if (dtvoteinfo != null)         {             if (dtvoteinfo.rows.count > 0)             {                 int.tryparse(dtvoteinfo.rows[0]["total_vote"].tostring(), out currentvote);                 int.tryparse(dtvoteinfo.rows[0]["my_voting"].tostring(), out myvoting);             }         }         ltrvotes.text = currentvote.tostring();         hfcurrentvote.value = currentvote.tostring();         hfmyvote.value = myvoting.tostring();          // ...snipped brevity...     } }

the control markup (uservote.ascx) looks like:

<div class="vote-cell" style="width: 46px; height: 92px">   <img src ="~/usercontrols/vote/images/arrow up.png"          id = "voteupoff"          runat = "server" alt ="vote up"          class="voteupimage"          style="height: 45px; width: 45px"/>   <div class="vote" style ="text-align:center; color:#808185;font-weight:bold;">     <asp:literal id="ltrvotes" runat="server" ></asp:literal>   </div>   <img  src ="~/usercontrols/vote/images/arrow_down.png"          id ="votedownoff"          runat = "server" alt = "vote down"         class = "votedownimage"          style="height: 45px; width: 44px; margin-left: 0px;" /> </div>

my page code-behind (viewanswer.aspx.cs) looks like:

uservote voteing = (uservote) **what write here...**.findcontrol(voting) voteing.objecttype =300; voteing.object id= 2;

my page markup (viewanswer.aspx) looks like:

<klmsuc:voteing id="voteing" runat="server" />

not sure if you're trying access currentvote value in usercontrol aspx page if are:

public partial class uservote : system.web.ui.usercontrol {     private int _currentvode;     private int _myvoting;      // move data access oninit because otherwise page_load on page     // fires before control page_load.     protected override void oninit(eventargs e)     {         datatable dtvoteinfo = showvotedetail(objecttype, objectid);         if (dtvoteinfo != null)         {             if (dtvoteinfo.rows.count > 0)             {                 int.tryparse(dtvoteinfo.rows[0]["total_vote"].tostring(),                              out _currentvote);                 int.tryparse(dtvoteinfo.rows[0]["my_voting"].tostring(),                              out _myvoting);             }         }     }      protected void page_load(object sender, eventargs e)     {         ltrvotes.text = _currentvote.tostring();         hfcurrentvote.value = _currentvote.tostring();         hfmyvote.value = _myvoting.tostring();          // set img src snipped brevity....     }      public int currentvote     {         { return _currentvote; }     }      public int myvoting     {         { return _myvoting; }     } }

on aspx page add following directive register control:

<%@ register src="~/uservote.ascx" tagprefix="klmsuc" tagname="voteing" %>  <!-- had --> <klmsuc:voteing id="voteing" runat="server" />

in aspx code-behind:

int currentvote = voteing.currentvote; int myvote = voteing.myvoting;

if you're using vs2008 or later shouldn't have use findcontrol. if see willem's answer.
