Hi

I'm using a radtreeview on a page with a an radajaxmanager and from a contextmenu I'm trying to get a number of things to happen. My problem is this: when the treeview and contextmenu is originally created (before any postback) everything is fine and every event is executed as expected, but after postback the contextmenu appears somewhat strange, without the arrows to indicate submenus and it does not trigger any events.

I'm using a straight forward event - handler pattern on the treeview and the contextmenu :

(the class inherits radtreeview)

this.ContextMenuItemClick += new RadTreeViewContextMenuEventHandler(OrganizerTreeView_ContextMenuItemClick);

and a event handler:
protected void OrganizerTreeView_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)

I create the treeview and the contextmenu dynamically and I add the treeview anew on Page_PreRender if IsPostBack is true.

Any ideas?

kind regards

Slow by comparison

Hello,

I was taking a first look at the online demos of the classic RadGrid vs. the RadGrid Prometheus. When I compare the two on the demo website, it appears that the Prometheus version is noticeably slower than the classic version for things like sorting, and especially paging.

I obviously want to start working with the Prometheus version, but am concerned that there is a significant performance hit.

Does anyone else notice this? Perhaps it has been discussed already...

Thanks,
Chris

RadUpload and MultiView in Safari 3

Hi,

I seem to be having a Safari-specific problem involving a MultiView and RadUpload. If the RadUpload control is present in a View of a MultiView that is not the active View, then Safari does not render the control properly. Upon viewing the WebInspect Console, the following error is obtained:

      Sys.ScriptLoadFailedException: The script 'http://localhost/deltanet/ScriptResource.axd?d=KHlrNZ2Q4IDiiwop_XNJxkQGN1i2x-sO6rt-iO3fB2zZXzp8EjGBcFdHrYUZ61jWPpt9H4Hsf4_3abAyDCQU0A2&t=633438057580000000' failed to load. Check for: Inaccessible path. Script errors. (IE) Enable 'Display a notification about every script error' under advanced settings. Missing call to Sys.Application.notifyScriptLoaded().

This problem does not occur when:
- the RadUpload control is not within a View control
- the active View is defaulted to the View with the RadUpload control in it
- using any other browser besides Safari 3

Any ideas?

The aspx code and code behind follows. Note that the switching of the Views is triggered by a click of the "Switch to Next View" button.

Memory usage in RadUpload

During stress testing of RadUpload I have experienced that the memory consumption on the webserver increases dramatically when uploading.

This is no surprise as we are testing with a lot of data, but I am getting quite concerned about the general memory usage of the component.

Lets say for instance that we have:
10 user each uploading 25 files of 35 mb's at the same time amounting to roughly 9gb of data.

So can you give a rough overview of the maximum memory usage in this scenario? (data only ofcourse, not objects etc.) - and what and when the data is in the memory. Are all files for each user in memory simultaneously? Or only 1 at a time?

Hope you can enlighten me

BR.

            </body> 
        
            </html>

when I enable the aggregate by using:
col.Aggregate = GridAggregateFunction.Sum;

it gives me error
"Column 'ProductName' does not belong to table"
in the RadGrid.Rebind();

anyone know why this happens?
Thx

commitchanges and serverside

hi all,

i am developing a page with a treeview where people can add and delete nodes clientside. My idea was to do this with trackchanges and commitchanges at each action of the user, WITHOUT going to the server at that point.
So if an user adds 2 nodes, the server does not know this at the moment.

I will only go to the server when the user chooses for a SAVE, this happens with a button. But.... does the button have to callback the treeview from the server to the client as well? Cause if i do not do this, i will get an index out of bounds the second time i press the SAVE button. (or when i add nodes, nodes get added each time i have a postback to the server).

What i want is that i can do changes at the client, and commit them to the server at the time the user chooses to save the data. BUT! i do not need / want to have to callback the data from the server back to the client, cause i allready know 100% sure my client state is the same as on the server.

I think above has something to do with the client state? Without a callback of the treeview from server to client, this is not emptied, but it is applied to the server (at poostback) by the clientside call commitchanges?

Cheers and thx,

TreeView
