c# - UserControl not rendering correctly -

i have 2 usercontrols , 1 view. have grid button when clicked, sends object parent (the view) , uses object update second control. problem though when debug it, once page renders again, second usercontrol still not visible , textbox remains empty.

the first usercontrol called ctrlmyroster ascx:

<%@ register assembly="telerik.web.ui" namespace="telerik.web.ui" tagprefix="telerik" %>  <telerik:radgrid id="radgmyrosters" cssclass="radgmyrosters" runat="server" allowpaging="true" allowsorting="true" autogeneratecolumns="false" onitemcommand="radgmyrosters_itemcommand">     <mastertableview>         <columns>             <telerik:gridboundcolumn datafield="rostername" headertext="rostername" datatype="system.string" uniquename="rostername">             </telerik:gridboundcolumn>             <telerik:gridtemplatecolumn headerstyle-cssclass="grid-header" headerstyle-width="51px" itemstyle-horizontalalign="center" itemstyle-verticalalign="middle">                 <itemtemplate>                     <asp:button id="btneditroster" runat="server" cssclass="btngreen" commandname="edits" text="edit"></asp:button>                 </itemtemplate>             </telerik:gridtemplatecolumn>         </columns>     </mastertableview> </telerik:radgrid> 

ctrlmyroster codebehind

protected void page_load(object sender, eventargs e) {     radgmyrosters.datasource = lstuserscurrentroster; }  public event eventhandler editbuttonclicked;  private void oneditbuttonclick(int rowselected) {     if (editbuttonclicked != null)     {         editbuttonclicked(lstuserscurrentroster[rowselected], eventargs.empty);     } }  protected void radgmyrosters_itemcommand(object sender, telerik.web.ui.gridcommandeventargs e) {     if (e.commandname == "edits")     {         oneditbuttonclick(e.item.itemindex);     } } 

the second usercontrol ctrlrosterdetail ascx

<%@ register assembly="telerik.web.ui" namespace="telerik.web.ui" tagprefix="telerik" %>  <asp:label id="lblname" runat="server"> name: </asp:label><asp:textbox id="txtrostername" runat="server" ></asp:textbox> 

ctrlrosterdetail codebehind

protected void page_load(object sender, eventargs e) {    //empty } 

viewmyroster ascx:

<%@ register assembly="telerik.web.ui" namespace="telerik.web.ui" tagprefix="telerik" %> <%@ register src="usercontrols/ctrlmyrosters.ascx" tagname="ctrlmyrosters" tagprefix="mycontrols" %> <%@ register src="usercontrols/ctrlrosterdetails.ascx" tagname="ctrlrosterdetails" tagprefix="mycontrols" %> <telerik:radajaxpanel runat="server" id="rapcreatewindowcontainer" loadingpanelid="ralploadingpanel">      <aau:ctrlmyrosters id="ctrlmyrosters1" runat="server" />     <aau:ctrlrosterdetails id="ctrlrosterdetails1" runat="server" visible="false" /> </telerik:radajaxpanel> 

viewmyroster codebehind

protected void page_load(object sender, eventargs e) {     ctrlmyrosters1.editbuttonclicked += new eventhandler(ctrlmyrosters1_editbuttonclicked); }  private void ctrlmyrosters1_editbuttonclicked(object sender, eventargs e) {     ((textbox)ctrlrosterdetails1.controls[0]).text = ((eventroster)sender).name;     ctrlrosterdetails1.visible = true; } 

am missing something? maybe it's .net page lifecycle?

maybe should use different approach? want pass information first usercontrol second usercontrol.
