How to automatically populate a field with the sum of values from a previous record?

I have o datagrid with fields named "Start" and "Duration" like the rows drag and drop shipped orders one.
When I add a new record I would like it to autopopulate the "Start" field with the "Start+Duration" value from the previous record (Start2=Start1+Duration1)

Example Recordset
Record 1, Start=0, Duration=500
Record 2, Start=500, Duration=1000
Record 3, Start=1500, Duration = 100
Record 4, Start=1600, Duration = 1500
...

How could i achieve this?

Thank you very much.

Image src changed to include site name

Hi all:
I have a page created that has a RadEditor on it, with ImageManager enabled. When a user finds the image they want to insert, it pulls the site name along with the file path. Here are my settings for the editor:

myEditor.ImageManager.ViewPaths =

New String() {"~/i"}

This works fine as the user is directed to this folder. On insert, however, the src to the image holds details further back like this:
<img alt="" src="/mysite/i/Atlas_48.png" />

Is there a way to NOT have the '/mysite/' show up? I have this on a test server, and when I push it live my site name usually changes (ex. mysitedev turns to mysite), so I need to do a mass update with find and replace. I'm guessing I'm missing something. Any help is greatly appreciated.

Thanks,
TL

Index out of range when using RadAsyncUpload

Hi,

I use RadAsyncUpload along with custom handler to upload files to FTP but occasionally got the following errors and really don't understand how this happened. The stack trace of the error is as follows.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

at System.Collections.ArrayList.get_Item(Int32 index)
at Telerik.Web.UI.AsyncUpload.RequestData..ctor(HttpContext context)
at Telerik.Web.UI.AsyncUploadHandler.EnsureSetup()
at Telerik.Web.UI.AsyncUploadHandler.ProcessRequest(HttpContext context)
at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Any ideas?

Thanks,
Charlie

Using local images with RadEditor

I am creating an HTML editor using the RadEditor and I am running into an issue. I cannot upload files to the server that the control will be run on. Instead, when a user needs to add an image to an HTML page, they will need to reference a local file, i.e., <img src="file://c:/some_path/some_image.jpg />. Is there any way at all to use the image manager to look at files on the local computer and insert a reference to the local file instead of something on the remote server? If not, is there another way to easily do this?
