Hi there,

Our organization is using the FileExplorer control in one of our web applications for our end users to manage files.

There is a continuous request for being able to download all files from any given folder instead of downloading them one by one.

Does the latest version of FileExplorer support this feature? If not, is this on your roadmap for future releases?

Thanks,
Roger

RadAjaxManager / FullPostback / download...response.End : Error

Hi from France, from my home...

normally, I'm on vacation since Friday evening, but I had a problem with the finalization of my project during the weekend.

And i need help !

I've got an RadAjaxManager, 2 buttons set as PostBackControls

this buttons are in listview, this listview is ajaxified

Each item in listiew contains for clic on

2 radiobutton (grouped) AjaxPostback to set in database is selected and other things

2 buttons (1 per radiobutton) to download a generated document from Database and they must set a fullpostback on clic

uploadViewbutton ajaxPostback for opening a panel.to view Upload Zone (and put element id Selected in upload button commandArg)

My problem is i clic on fullPostback Buttons i've an error :

Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: Impossible d'analyser le message reçu du serveur. Cette erreur peut avoir plusieurs causes possibles : réponse modifiée par des appels à Response.Write(), filtres de réponse, HttpModules ou activation de trace du serveur.
Détails : Erreur d'analyse à proximité de 'PK

My code behind fullpostback to download document :

With Response

Dim filename As String = strLibelle & "." & strExtension

.Clear()

.ContentType = strType

.AddHeader("Content-Disposition", "attachment; filename=" & filename)

.AddHeader("content-length", bFile.Length.ToString)

.BinaryWrite(bFile)

.End()

End With

RadAsyncUpload - Cannot find the temporary file

Dear telerik team,

I've some problem using RadAsyncUpload [Q2 2010 .Net 3.5].
When I want to save uploaded file to the specified folder, sometime it raised error exception: cannot find [temporary file location]. You can see error message on the pic attached.

This problem doesn't always occur, means sometime I can successfully save the file.
Below is my code when for saving the file:

If RadAsyncUpload1.UploadedFiles.Count > 0 Then

For Each validFile As UploadedFile In RadAsyncUpload1.UploadedFiles

Dim targetFolder As String = Server.MapPath("~/uploadedFile/")

If Not Directory.Exists(targetFolder) = True Then

Directory.CreateDirectory(targetFolder)

End If

validFile.SaveAs(Path.Combine(targetFolder, validFile.FileName), True)

Next

End If

Thank you..

Radscheduler doing a postback

Hi Telerik,

I have a page where the Radscheduler control is used. The only problem is when i try navigate between dates using "<" Today ">" icons section (which comes as part of the control)it does a post back and the entrie page gets refreshed. I have added the RadAjaxManager to restict the post back for few buttons and Radscheduler itself but that doesnt seem to work.

am i missing any thing? I havent added any code at .cs level which i think is the entire idea of code less ajax implementation.
Please suggest a way to solve this.

Thanks and Regards,
Adi.

ComboBox on the iPad/iPhone

Many users have begun using our website on their iPads and iPhones. At present, it appears that Telerik doesn't fully support these platforms with RadControls... for example, the RadComboBox is not treated like a dropdown natively by the Safari browser (i.e. using the native picker); instead, it is displayed as it would be on a desktop browser.

Are there any plans to include full mobile Safari support in the near future?

Many thanks,

Jake

File Filter Doesn't Work

Hi,
I need to filter the files displayed in the browse dialogue window based on file types. I am using RadAsyncUpload control to
accomplish this.

When I browse in FF, I can see two browse button displayed. Clicking on first browse button doesn't open dialogue with file lists. Attached the image. I want a simple file upload control with single browse button. I had a similar issue in IE but resolved by adding the following. But issue still persists in FF.

<TeleControl:RadStyleSheetManager runat="server" ID="RadStyleSheetManager1"> </TeleControl:RadStyleSheetManager>
When I browse with applying file filter for Image files(jpg,png), It shows all files in the open dialogue window instead of showing only those files with extension .jpg or .png. Attached the screen shot. But when I refresh the page it works fine.
Can you please explain how does this file filter works in RadAsyncUpload w.r.t browsers. As far as I know, It depends on upload module. IE prefers silver light first where as FF prefers flash. Is that possible to make filters work in IE with having only flash (not silverlight)?. In which scenario does this combination (IE or FireFox with only flash) fails?.

Please find the aspx code:

<TeleControl:RadStyleSheetManager runat="server" ID="RadStyleSheetManager1"></TeleControl:RadStyleSheetManager

<TeleControl:RadAsyncUpload ID="RadAsyncUpload1" runat="server"

<Localization Select="Browse"

/>

</TeleControl:RadAsyncUpload>

C# (asp.net page behind):

protected void Page_Load(object sender, EventArgs e)

{

var filter = new FileFilter();

filter.Description = "Image files(jpg,png)";

filter.Extensions = new string[2];

filter.Extensions[0] = "jpg";

filter.Extensions[1] = "png";

RadAsyncUpload1.FileFilters.Add(filter);

}

Custom RadDateInput validators error on ID property

Environment:
ASP.NET 3.5, VS2008 professional, C#, Windows7, IE8
RAD Control v 2010.1.309

I am creating an extended server control that inherits from the RadDateInput. The reason for this approach is that I want to be able to dynamically add asp.net validation controls based on a property that is set from the code behind of the containing page.

I have successfully accomplished this with an asp.net text box (and other asp.net controls). I override the CreateChildControls method. Next I dynamically create the needed validation controls. I set the ControlToValidate property of the asp.net validation control to the ID property of the Telerik control (as set in the asp.net page). So, if I'm generating a Required Feild validator, it might look like this

RequiredFieldValidator1.ControlToValidate = RadDateInput1.ID;

I get a runtime error "Unable to find control id 'RadDateInput1' referenced by the 'ControlToValidate' property of 'RequiredFieldValidator1'.

Note that this same approach does work with an ASP.NET text box. So my question is how can I determine what the ID of the RadDateInput is in my custom control?

Thanks!
