Asyncupload and Cannot create an object of type 'System.String'

[Fabio Cirillo]

Hi
i've this code:

    <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" height="200px"
        width="112px">
        <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" Culture="it-IT"
        OnClientValidationFailed="OnClientValidationFailed" OnClientFileSelected="fileSelected" OnClientFileUploaded="fileUploaded"
        AllowedFileExtensions="jpeg,jpg,gif,png"
Localization-Remove="Rimuovi" Localization-Select="Cerca" MaxFileSize="5000000">
            <FileFilters>
                <telerik:FileFilter Description="Images(jpeg;jpg;gif;png)"
                Extensions="jpg,jpeg,gif,png" />
            </FileFilters>
            <Localization Cancel="Annulla trasferimento" Select="Cerca" Remove="Rimuovi" />
        </telerik:RadAsyncUpload>

but when i start the page there is this error: Cannot create an object of type 'System.String[]' from its string representation 'jpg,jpeg,gif,png' for the 'Extensions' property. Why?

Thanks

Hello Fabio,

 
We are aware of this issue(it is observed only in the 2012.3.1205 version of our controls) and it is already fixed (you could test our latest internal build). In case you don't  want to upgrade right now again  you can avoid the exception by removing the filters declaration from mark up and set it from the code behind. Here is an example how it should look like:

protected void Page_Load(object sender, EventArgs e)
   {
       var filter = new FileFilter();
       filter.Description = "my desc";
       filter.Extensions = new string[2];
       filter.Extensions[0] = "doc";
       filter.Extensions[1] = "jpg";
       RadAsyncUpload1.FileFilters.Add(filter);
   }

Hope this will explain the issue and be helpful.
