ASPxFileManager - Script error is thrown when a selected item does not exist in the control hierarchy after a postback

created 9 years ago (modified 9 years ago)

I have submitted a support ticket earlier (yesterday) on the same subject.
I thought the problem was solved, but it is not.
The problem is:
I have a combobox which opens the enabled folders fo a user depending on his logon info.
The filemanager is opened according to the selected folder in the combobox.
This seems to work ok when you are in the same root folder, but whyen you change the rootfolder it "hangs".
The example you made at devexpress has the same rootfolder all the time

Code for the combobox:

ASPx
<dx:ASPxComboBox ID="cboDineMapper" runat="server" DataSourceID="SqlDineMapper"  
           TextField="Mappe" ValueField="Mappe" ValueType="System.String" AutoPostBack="True" OnSelectedIndexChanged="cboDineMapper_SelectedIndexChanged" NullText="Velg mappe">  
</dx:ASPxComboBox>

C#

C#
protected void cboDineMapper_SelectedIndexChanged(object sender, EventArgs e)  
   {  
       string strValgtMappe = cboDineMapper.SelectedItem.ToString();  
       ASPxFileManager2.Visible = true;  
       ASPxFileManager2.Settings.RootFolder = "~/Mapper/" + strValgtMappe;  
   }

Code for the FileManager:

ASPx
<dx:ASPxFileManager ID="ASPxFileManager1" runat="server" EnableTheming="True" Theme="Glass" Height="410px" Width="468px"  
                OnSelectedFileOpened="ASPxFileManager1_SelectedFileOpened" ToolTip="Dobbelklikk for å velge fil til vedlegg" >  
                <Settings RootFolder="~\Mapper" ThumbnailFolder="~\Mapper" InitialFolder="~\Mapper" />  
                <SettingsFileList View="Details">  
                    <DetailsViewSettings>  
                        <Columns>  
                            <dx:FileManagerDetailsColumn Caption="Filnavn" FileInfoType="FileName" Width="180">  
                            </dx:FileManagerDetailsColumn>  
                            <dx:FileManagerDetailsColumn Caption="Dato endret" FileInfoType="LastWriteTime" Width="90">  
                            </dx:FileManagerDetailsColumn>  
                        </Columns>  
                    </DetailsViewSettings>  
                </SettingsFileList>  
                <SettingsEditing AllowDownload="True" AllowCreate="True" AllowDelete="True" />  
                <SettingsToolbar ShowFilterBox="False" ShowPath="False">  
                </SettingsToolbar>  
                <SettingsLoadingPanel Text="Vent...&hellip;" />  
                <Styles>  
                    <File Width="80px">  
                    </File>  
                    <FolderContainer Width="150px">  
                    </FolderContainer>  
                </Styles>  
</dx:ASPxFileManager>

      I have installed the hotfix and upgraded my project, but how do I know that the hotfix
      have been implemented, because my references all say 15.7 and not 15.1.78

        Hello Reidar,
        If I understand you correctly, you expect the 15.1.8 version to be displayed in your references. The current installation tool is a hotfix, i.e. the fixed 15.1.7. So, the version will be also displayed as 15.1.7. You can check the version you're using in the list of installed programs on your OS or by invoking the ASPx.VersionInfo  in the browser console for your web application.
        The "Fixed in builds: 15.1.8" line means that when the 15.1.8 version is released, it will include the current fix.

        Hi,

        Once you changed the RootFolder and Visible properties on a postback (in the SelectedIndexChanged event handler), they need to be restored on further trips to the server in the Page.Init/ASPxFileManager.Init  event handler. For example,  you can use the Session object to store the current path.

        Let us know if this helps.

              If you please could make it high priority. This is the last point from delivery to my customer, and I want to start on Part 2 of the application.
              Thank you in advance.
