devexpress - ASPxGridview undefined -

i have basic 1 table grid. have field called branch type. branch type can corporate or franchise. when click on edit button on aspxgridview row , display , hide fields on edit form, depending on branch type is. if corporate display manager field , hide owner field. when branch type franchise owner field displayed , manager field hidden on edit form. details can show on grid view on edit form force user fill in applicable fields.

if below:

this want achieve on loading edit form :

  protected void aspxgridviewstores_celleditorinitialize(object sender, aspxgridvieweditoreventargs e)  {   if (!aspxgridviewstores.isediting || e.column.fieldname != "storeownershipid") return;     if(e.keyvalue == dbnull.value || e.keyvalue == null) return;     object val = aspxgridviewstores.getrowvaluesbykeyvalue(e.keyvalue, "s_id");     if(val == dbnull.value) return;     int storeownershipid = (int32)val;      if (storeownershipid == 4)     { aspxcombobox managerid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("managerid");         managerid.enabled = true;         aspxcombobox contactid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("contactid");         managerid.enabled = true;      }     else     { aspxcombobox managerid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("managerid");         managerid.enabled = false;         aspxcombobox contactid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("contactid");         managerid.enabled = false;     }  } 

and depending on selecting corporate or franchise in "storeownershipid" field use client side script enable or disable additional fields.

i have done research well, , came following code:

selectedindexchanged="function(s, e) {       var value = s.getvalue();     if(value == 4)         gridviewstores.geteditor("ownername").setvisible(true);     else          gridviewstores.geteditor("ownername").setvisible(false); }" 

but when called following error:

microsoft jscript runtime error: 'gridviewstores' undefined

i have added httphandler in web.config:

<httpmodules>   <add type="devexpress.web.aspxclasses.aspxhttphandlermodule, devexpress.web.v10.2, version=10.2.4.0, culture=neutral, publickeytoken=b88d1754d700e49a" name="aspxhttphandlermodule" /> </httpmodules> 

and

<system.webserver>     <modules>       <add type="devexpress.web.aspxclasses.aspxhttphandlermodule, devexpress.web.v10.2, version=10.2.4.0, culture=neutral, publickeytoken=b88d1754d700e49a" name="aspxhttphandlermodule" />     </modules> 

as can see below have inserted clientinstancename,

i have changed clientidmode autoid inherit static predictable , each scenario not work , still renderes : microsoft jscript runtime error: 'aspxgridview' undefined.

below gridview tag

<dx:aspxgridview id="aspxgridview" runat="server" autogeneratecolumns="false"      clientidmode="predictable" datasourceid="sqldatasource1" keyfieldname="s_id"      clientinstancename="aspxgridview"> 

i have tried creating new page sqldatasource , gridview storetype field acombobox , including javascript mentioned in previous posts.. , no luck @ all. have given web.config settings declared httphandler, else suggest working?

here webconfig:

section enables configuration of security authentication mode used asp.net identify incoming user. --> section enables configuration of if/when unhandled error occurs during execution of request. specifically, enables developers configure html error pages displayed in place of error stack trace.

    <customerrors mode="remoteonly" defaultredirect="genericerrorpage.htm">         <error statuscode="403" redirect="noaccess.htm" />         <error statuscode="404" redirect="filenotfound.htm" />     </customerrors>     --> <httpmodules>   <add type="devexpress.web.aspxclasses.aspxhttphandlermodule, devexpress.web.v10.2, version=10.2.4.0, culture=neutral, publickeytoken=b88d1754d700e49a" name="aspxhttphandlermodule" /> </httpmodules>  <httphandlers>   <add type="devexpress.web.aspxclasses.aspxhttphandlermodule, devexpress.web.v10.2, version=10.2.4.0, culture=neutral, publickeytoken=b88d1754d700e49a" verb="get" path="dx.ashx" validate="false" />  </httphandlers>  <pages controlrenderingcompatibilityversion="3.5" clientidmode="autoid" /> 

sorry looong question. way using devexpress gridview. guys devexpress cant me , tak 1 day answer question, been going on week now...

thank werner

the java script case sensitive language. so, if clientinstancename set aspxgridview, code should be:

aspxgridview.geteditor("ownername").setvisible(true);

i see error message contains 'aspxgridview;' identifier. means code contains aspxgridview identifier should use aspxgridview (based on mark up). also, believe code wrong:

if (storeownershipid == 4)     { aspxcombobox managerid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("managerid");         managerid.enabled = true;         aspxcombobox contactid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("contactid");         managerid.enabled = true;      }     else     { aspxcombobox managerid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("managerid");         managerid.enabled = false;         aspxcombobox contactid = (aspxcombobox)aspxgridviewstores.findeditformtemplatecontrol("contactid");         managerid.enabled = false;     } 

you set enabled property of managerid object twice same value. please check it. have nothing add. if not help, please let me know support center ticket id , if possible attach source code of page (cs , aspx) , web.config there. try you.

update: have found question in support center , answered it. hope, helps.
