unable to obtain extraparams from a button ajaxEvent (0.8.2) inside Asp.Net itemTemplate

[unaltro2]

Hello,

I'm unable to obtain extraparams values from an AjaxEvent fired from a button click event.

The button is inside a Asp.Net ListView itemTemplate,

and the value i'd like to pass on server-side is embedded dinamically with the 'Eval' function.

I'm able to pass every kind of string but this is not what i would.

easiest markup:

                                 <asp:ListView 
                               ID="ListViewDoc_Richieste" 
                               GroupItemCount="16" 
                               runat="server" 
                               DataKeyNames="ID" 
                               DataSourceID="objectDataSource_Richieste_Doc" >    <------------ returns 'Name' and 'Estensione' values                              
                                                             
                               <LayoutTemplate>
                                  <asp:Placeholder
                                    id="GroupPlaceholder"
                                    runat="server" />
                               </LayoutTemplate>
                                  
                               <GroupTemplate>
                                  <div>
                                     <asp:Placeholder id="ItemPlaceholder" runat="server" />
                                  </div>
                               </GroupTemplate>
                                  
                               <ItemTemplate>   
                                  <asp:UpdatePanel ID="updatePanelDocsRichieste_Documenti" runat="Server">
                                      <ContentTemplate >         
                                                                         
                                           <ext:Button runat="server" ID="btnOpen" Text='<%# Eval("Nome").trim() + "." + Eval("Estensione").tolower.trim() %>' > 
                                              <AjaxEvents >
                                                 <Click OnEvent="btnOpenFile" IsUpload="True" Before="Ext.Msg.wait('Waiting...', 'Downloading...');" Failure="Ext.Msg.show({title:'Download Error', msg:result.errorMessage, buttons: Ext.Msg.OK, icon:Ext.MessageBox.ERROR});">
                                                   <EventMask ShowMask="true" MinDelay="500" Msg="Please wait..."   />
                                                   <Confirmation  ConfirmRequest="true"  Title='<%# Eval("Nome") %>' Message="Do you wish to open selected doc?"></Confirmation>               
                                                   <ExtraParams>
                                                      <ext:Parameter Name="myName" Value='<%# Eval("Nome").tostring.trim %>' ></ext:Parameter>
                                                      <ext:Parameter Name="myExtension" Value='<%# Eval("Estensione") %>'  ></ext:Parameter>
                                                   </ExtraParams>
                                                 </Click>                                                                                            
                                              </AjaxEvents>
                                           </ext:Button>     
                                                                                                                                           
                                      </ContentTemplate> 
                                  </asp:UpdatePanel> 
                               </ItemTemplate>
                              
                              </asp:ListView>

server-side:

 Protected Sub btnOpenFile(ByVal sender As Object, ByVal e As AjaxEventArgs)        
        Dim _estensione As String = e.ExtraParams("myExtension")   <------------------------------------- is returned an empty string!!!!!!!!!!!!!!!!!!!!!
        Dim _nome As String = e.ExtraParams("myName")   <------------------------------------- is returned an empty string!!!!!!!!!!!!!!!!!!!!!

I guess the issue is on extraparams;in this case what else property i need to set on the ajaxEvent?

Thanks a lot.

Fabio.
