control number of files with multi-file selection

Is there a way to control how many a user can select when using the multi-file selection feature for 2011.2.915?

1) limit the number of file selection in the file open dialogue?
2) preventing files from being uploaded after a set number of successful uploads?
3) hiding the selection control once a set number of files are uploaded successfully?

And is there a way to control what upload module to be used? e.g. I want to use Silverlight as much as possible.

Thanks in advance for any idea.

The RadWindow i have added:

My aspx page loads user controls (ascx) dinamically

Programmatically Created RadAjaxManager won't work properly

I'm programmatically creating a RadAjaxManager object as I'm creating custom webservercontrol that wraps the Grid, ContextMenus, and a Loading Panel to do some custom operations.

So far, I've been unable to get the RadAjaxManager to operate as it does when it's added directly to a page. The loading indicator doesn't show up on the grid at all, and I consistently get an error when attempting to fire Rebind on the grid from an ajaxRequest:

'ctl00_MainContent_SpreadsheetControl_ctl00_MainContent_SpreadsheetControl_MainGridPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.

The code used to create and initialize the objects is below.
Any idea what the issue could be?

protected void CreateControls() //Called from CompositeControl constructor

{

AjaxManager = new RadAjaxManager() { ID="AjaxManager", EnableAJAX = true};

InputManager = new RadInputManager() { EnableEmbeddedBaseStylesheet = false };

CellContextMenu = new RadContextMenu() { ID = "CellContextMenu", OnClientLoad = "onCellContextMenuLoad" };

HeaderContextMenu = new RadContextMenu() { ID = "HeaderContextMenu", OnClientLoad = "onCellContextMenuLoad" };

LoadingPanel = new RadAjaxLoadingPanel() { ID = "RadAjaxLoadingPanel" };

Grid = new RadGrid()

{

ID = "MainGrid",

AutoGenerateColumns = false,

AllowMultiRowEdit = true,

CellSpacing = 0,

CellPadding = 0,

GridLines = GridLines.None,

AllowAutomaticUpdates = true,

AllowFilteringByColumn = true,

AllowSorting = true,

GroupingEnabled = false,

ShowGroupPanel = false,

};

}

protected void InitializeComponent() //called from 'CreateChildControls' override.

{

this.Controls.Add(AjaxManager);

Grid.ClientSettings.Scrolling.AllowScroll = true;

Grid.ClientSettings.Scrolling.UseStaticHeaders = true;

Grid.ClientSettings.ClientEvents.OnGridCreated = "onGridCreated";

Grid.ClientSettings.ClientEvents.OnRowCreated = "onRowCreated";

Grid.ClientSettings.ClientEvents.OnRowDestroying = "onRowDestroying";

Grid.ClientSettings.ClientEvents.OnRowContextMenu = "onRowContextMenu";

Grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Bottom;

Grid.MasterTableView.EditMode = GridEditMode.InPlace;

Grid.MasterTableView.AllowCustomSorting = true;

this.Controls.Add(Grid);

this.Controls.Add(CellContextMenu);

this.Controls.Add(HeaderContextMenu);

this.Controls.Add(LoadingPanel);

Grid.PreRender += OnPreRender;

Grid.ItemDataBound += OnItemDataBound;

}

protected override void OnLoad(EventArgs e)

{

//base.OnLoad(e);

RadScriptManager.RegisterStartupScript((Control)this, this.GetType(), this.AjaxManager.ClientID, "identifyAjaxManager('" + AjaxManager.ClientID + "');", true);

AjaxManager.AjaxSettings.AddAjaxSetting(Grid, Grid, LoadingPanel);

AjaxManager.AjaxSettings.AddAjaxSetting(AjaxManager, Grid);

}

}
