View 3 RepliesWhen selecting an image for an item in file upload control of ajax toolkit (AsyncFileUpload), the only files that should be displayed are ".jpg, .jpeg, .gif, .bmp, or .png".
I currently can see every type of file.
We are running following javascript function:
function btn_AddToList_Click() {
var filePath = document.getElementById("FileUpload").value;
if(filePath.length > 0)
{
var opt = new Option(filePath,filePath);
var listBox = document.getElementById("ListBox");
listBox.options[listBox.options.length] = opt;
}
}
Function binding:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
btn_AddToList.Attributes.Add("onclick", "btn_AddToList_Click(); return false;");
}
}
HTML:
asp:FileUpload ID="FileUpload" runat="server" Width="394px"
asp:ListBox ID="ListBox" runat="server" Width="394px"
asp:Button ID="btn_AddToList" runat="server" Enabled="true" Text="Add"

I have decorated my base controller with a couple of action filters. They work fine.
One of those filters sets up the request - does things like set the culture based on the domain, etc.
I also have a handful of actions that require authorization using the Authorize attribute.
My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.
The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.
I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.

I've getting so far, but cannot seem to work out how to add the default value to the controller and pass that value to my actionfilter.
