refresh grid using script with NeedDataSource

How can I refresh a grid using script when I'm using a RadGrid1_NeedDataSource? I've tried most of all of the sugestions in the forum but nothing seems to work. I have a time stamp column in my datasource so I can tell when it was last updated.
My last attempt was
function refreshGrid()
{
$find("<%= RadGrid1.ClientID %>").get_masterTableView().rebind();
}

Update information. I'm using a usercontrol in DotNetNuke6. I've researched and it seems that its mostly an issue with the radAjaxManager. I'm still haveing problems with putting the manager on the parent page programmatically from the user control. I'm using

Dim manager As New RadAjaxManager()

manager.ID = "RadAjaxManager1"
Me.Page.Form.Controls.Add(manager)
But I don't think it is getting registered. If I can't get this last part to work I'm going to have to redo the entire structure.

As a hack work around a put a page refresh in the function OnClientClose

window.location.reload(true);
It's not very smooth but gets the job done for now. Is there a better way?

Added information: I'm moving this question over to the Ajax forum since it more of an issue with the RadAjaxManager than with the RadGrid. Sorry for the post but I did not see a way to delete.

Thanks

set_value fires OnClientRating event

Hello,

I have a situation where I load a RadRating control alongside a video to allow users to rate it. I have a client side method attached to the "OnClientRating" event to capture the user entry and save it into the database.

Below it, I have a grid of other videos. When a user clicks on the one of the videos in the grid, I get the current rating value for that video and try to set it to the rating control via the "Rating.set_value" client side api method. However, this is causing the control to fire the "OnClientRating" event again, with the current value as the rating. This causes a new "rating", but it was not initiated by the user, but rather via the the "set_value" method.

Is there a way to NOT fire the OnClientRating event when executing the "set_value" method? Or, is there another way I should approach this?

Thank you.

Custom InsertCommand

I have followed most of the following thread:
http://www.telerik.com/community/forums/aspnet-ajax/grid/custom-insertcommand.aspx
However I can't get the radwindow to show. If I run the code from a button click event it opens and displays fine if I run it from the

RadGrid1_ItemCommand then it does not show. I know that event is firing since I have a trace log file within the process.

If e.CommandName = RadGrid.InitInsertCommandName Then

e.Canceled = True

Dim newwindow As Telerik.Web.UI.RadWindow = New Telerik.Web.UI.RadWindow()

newwindow.ID = "RadWindow1"

newwindow.NavigateUrl = "/portals/0/NewEducation.aspx?RecID=0"

newwindow.OnClientClose = "OnClientClose"

newwindow.Width = New Unit(650)

newwindow.Height = New Unit(580)

newwindow.VisibleOnPageLoad = True

newwindow.Modal = True

RadWindowManager1.Windows.Clear()

RadWindowManager1.Controls.Add(newwindow)

End If

Please help. Thanks

My grid is in an asp.update panel

Added information. It seems that it's an issue with Ajax. I removed the asp.update panel and it works fine but with a postback I added a

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

and again it does not show. Is there a way to have the best of both worlds? Ajax and also a custom window when the add new record is clicked?

Where do I put the RadScriptManager or ScriptManager

Hello,

On page 25, section 1.6, it states:

"RadControls for ASP.NET AJAX requires a ScriptManager before any of the controls on the page. You may instead use the RadScriptManager although it is not required. RadScriptManager has some optimization capabilities that can be used for maximum performance."

I ran the first application from the Training Guide (PDF page 34), and I am getting the below error about the web.config file and using the SmartTag to configure this control as well as the RadScriptManager control:

'~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

Where does this control belong on the page and how do I fix the web.config so that this lesson can run in the browser correctly?

Thanks,
R2

"Tokenizing"

Just a suggestion really;

Think this would be a good feature to implement for radtextbox / radcombobox in future.
