Problem with AsyncUpload and User Control .ascx files

[Brett]

I am having issues using the AsynUpload control and .ascx files.  It's almost like it doesn't work with them at all.  I try to use the clientside development and the server side development and either I get errors or it just doesn't fire.  What can I do to alleviate this issue?

Hi Brett,

The provided information is not enough to replicate the issue. Please have a look into the sample code snippet which works fine at my end. 

ASPX:

<uc1:Asyncupload ID="Asyncupload1" runat="server" />

ASCX:

<telerik:RadAsyncUpload ID="rasyncuploadUserControl" runat="server" OnClientFileUploaded="getFileName">
</telerik:RadAsyncUpload>
<telerik:RadButton ID="rbtnUpload" runat="server" Text="Upload" OnClick="rbtnUpload_Click">
</telerik:RadButton>

JavaScript:

function getFileName(sender, args) {
    alert(args.get_fileName());
}

ASCX.CS:

protected void rbtnUpload_Click(object sender, EventArgs e)
{
    int uploadedFileCount = rasyncuploadUserControl.UploadedFiles.Count;
}

Thanks,
Princy.
