How to pass server side values to sqldatasource?
Hi,

I'm using the SqlDataSource and Select Command with Parameters in the .aspx itself. I need to pass one of my Session and Query String values as the parameter value in the WHERE Clause of the Select statement in the Select Command. How can I pass the server side values (Session and Query String) in the SqlDataSource parameters?

[Solved] Binding Menu with Object Model
I have a pure object model that looks like this:

    [Serializable]
    public class NavigationModel
    {
        private IList<App> _applications;

        public IList<App> Applications
        {
            get { return _applications; }
            set { _applications = value; }
        }
    }

Each App contains an IList of Features.  I want to map this object model to the menu control.  Right now I have hierarchy through the object model and I want to keep it this way.  How would I do this?

Here is some of what I have tried with no success:
                _navigationModel = _navigationService.LoadData();
                TopMenu.DataSource = _navigationModel.Applications;
                TopMenu.DataFieldID = "Id";
                //TopMenu.DataMember = "Applications";
                //TopMenu.DataTextField = "Name";
                //TopMenu.DataValueField = "RelativePath";
                TopMenu.Flow = ItemFlow.Horizontal;
                RadMenuItemBinding appBinding = new RadMenuItemBinding();
                appBinding.Depth = 1;
                appBinding.TextField = "Name";
                appBinding.ValueField = "RelativePath";
                appBinding.DataMember = "Features";
                TopMenu.DataBindings.Add(appBinding);
                TopMenu.DataBind();

Thanks

Random AJAX timeouts
Hi Folks

I'm having some problems with the scheduler in that it randomly displays this error message.

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near 'Telerik.Web.UI 2008.'.

I'd like to know if you've seen this anywhere before and if so what would you suggest as the best course of action to either a) prevent it happening or b) methods of repeating the task that caused it to timeout. I think it's a timeout error but I could be wrong.

Thanks
Jon

http upload with ajax
Hello, I have the newest version of the Rad Controls and I have a web page with a fileupload on it along with some other form controls.  The user must submit the top part of the page and then the fileupload and a few other controls will then be enabled.  I'm using Ajax for this so the page doesn't look like it refreshes.  When I click the add file button i have to add the file from the FileUpload asp control, it doesn't see anything in the control.  I was wondering how to bypass this.  I've tried this javascript and I can't get it to work. I was wondering if htere's any other ways of making this work?
<script type="text/javascript">  
        function OnRequestStart(target, arguments) {  
            alert("here");  
            if (arguments.EventTarget == "<%# butFile.UniqueID %>") {  
                arguments.EnableAjax = false;  
                alert("Ajax disabled");  
            }  
        }  
</script> 

Here's some of my code: (upload file)
 Protected Sub butFile_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butFile.Click  
              Dim postedFile As HttpPostedFile = Me.FileUpload1.PostedFile  
 
        ' Validate   
        If Not postedFile Is Nothing AndAlso postedFile.ContentLength > 0 Then 
 
            ' Retreive the byte data   
            Dim b(postedFile.ContentLength - 1) As Byte 
            postedFile.InputStream.Read(b, 0, b.Length)  
            ' Insert into the database   
            Dim sqlConn As SqlConnection = GetSqlConnection()

                ' Configure the simple parameters   
                'sqlComm.Parameters.Add(New SqlParameter("@fileName", postedFile.FileName))  
                sqlComm.Parameters.Add(New SqlParameter("@fileName", Replace(FileUpload1.PostedFile.FileName, StrReverse(Mid(StrReverse(FileUpload1.PostedFile.FileName), InStr(1, StrReverse(FileUpload1.PostedFile.FileName), "\"))), "")))  
 
                sqlComm.Parameters.Add(New SqlParameter("@fileSize", postedFile.ContentLength))  
                sqlComm.Parameters.Add(New SqlParameter("@fileContentType", postedFile.ContentType))  
 
                ' Byte data   
                Dim paramBytes As New SqlParameter("@fileImage", Data.SqlDbType.Image, postedFile.ContentLength, "attachment")  
                ' Assign byte value   
                paramBytes.Value = b  
                sqlComm.Parameters.Add(paramBytes)  
 
                ' Open the connection and execute

Empty DIVs with RadAjax
We have a number of pages that use a RadAjaxManagerProxy (wired to a Manager on a master page) to turn on and off various asp:panels based on certain conditions. However, I've noticed that when the page re-renders, those panels that were explicitly set to be hidden show up as as a block-layout div, taking up vertical room on the page or control. When the controls are un-ajaxified and the page posts back, these hidden panels do not render as these "empty div" tags. Any suggestions on getting around this?

Thanks!

Any thoughts as to why the error?

Edit:  hmmm... clicking [ Upload ] in dialog...

- the Request Url is:
http://localhost/telerik.web.ui.dialoghandler.aspx?dialogname=imagemanager&skin=default&title=image%20manager&doid=<snip/>

- compared to mock-app that succeeds:
http://localhost/Telerik.Web.UI.DialogHandler.aspx?DialogName=ImageManager&Skin=Default&Title=Image+Manager&doid=<snip/>

It appears someone is mangling my url.  Who could that be?? 
Search continues...
