RadProgress during WCF call

I am working on an Import User function, which allows multiple users created for our application at one time (in Active Directory)

When the Import button is triggered using an Ajax call, the grid is processed during the postback, the values are retrieved from the grid, and a collection of user objects is passed to a WCF service.

While that service is processing the collection (anywhere from 1 - 250 users, or potentially more), I would like to be able to notify the user how many users have been imported.

The users are being created in Active Directory which slows down the process.
I'm not sure if the Ajax timed-out, but when I refreshed my grid, half the users showed up, and after a few other refreshes they all showed up.

My problem, is that I do not have a view of what is happening during the import process. For small batches it would be relatively quick.

But for larger batches, it looks like the Ajax Loading Panel will eventually stop, the grid will be refreshed, even though all the users have not completed being processed (created in Active Directory).

- How can I accomplish getting either progress synchronously, or asynchronously while the WCF service continues to process the user import request?

- And is there an demo, of getting the progress of a WCF service that is processing a collection of objects?

Scrollbar Size Not Correct When Adding in the Client

I'm using the same code used in the documentation to add items to a RadListBox on the client side. This is the page:

http://www.telerik.com/help/aspnet-ajax/listbox-client-object-api.html

Here is my ASPX:

<telerik:RadListBox ID="lstItems" Width="298" Height="495" runat="server" OnClientSelectedIndexChanging="changingItem">
</telerik:RadListBox>

And here is my JavaScript:
$find(pnlItemsId).expand();
var cboItems = $find(cboIntelligentSearchId).get_items();
var lstItems = $find(lstItemsId);
lstItems.trackChanges();
var ifrContent = $("#ifrContent")[0];
var currentItemKey;
if (ifrContent && ifrContent.contentWindow.getCurrentItemKey && typeof ifrContent.contentWindow.getCurrentItemKey == 'function')
{
currentItemKey = ifrContent.contentWindow.getCurrentItemKey();
}
var listItems = lstItems.get_items();
listItems.clear();
for (var i = 0; i < cboItems.get_count(); i++)
{
var cboItem = cboItems.getItem(i);
var itemName = cboItem.get_text();
var smItemId = cboItem.get_value();
var item = new Telerik.Web.UI.RadListBoxItem();
item.set_text(itemName);
item.set_value(smItemId);
listItems.add(item);
if (currentItemKey && currentItemKey == smItemId)
{
candidateSelectedNode = item;
selectedNode = item;
item.select();
}
}
lstItems.commitChanges();

When the JS finishes, the items appear in the ListBox, but the scrollbar appears as if it has, maybe, three items below the bottom of the ListBox and using the scrollbar shows about three additional items. However, approximately 100 items were added. The only way to get them to appear is to click on one of the items and use the down arrow to scroll to the bottom.

I've poked through the documentation as well as JS objects available on the ListBox and I've found no solution to the problem. Thanks in advance for your help.

Grid Layout Changes

Since updating to the latest version of Telerik I have noticed a few layout issues and wanted to check whether its intentional or whether there is an issue with my app.

On the first screenshot I am referencing the header context menu.

On the second screenshot I am referencing the fields all clumped together.

Please see the attached screenshots.

TreeList performance having more than 7000 rows

Hi Team,

I have a data containing more than 7000 rows. When I bind this data to treelist it takes more than 10 minutes to display on screen. So I implemented AllowLoadOnDemand feature. But when I used AllowLoadOnDemand then ExpandAllItems and AllowRecursiveSelection are not working properly.
I am facing below issues.

1. ExpandAllItems is not expanding to all levels.
2. If AllowRecursiveSelection is set to true, header check is not checked even if I click on header checkbox.

Can you please help me on this where I can use below features of TreeList
1. AllowLoadOnDemand = true with checkbox
2. ExpandAllitems
3. AllowRecursiveSelection
4. Improve Rendring of Treelist with more than 7000 rows

Please reply on this ASAP
Alok

RadUpload Progress Bar not updating

I have an ASP.NET user control "Upload.ascx" that contains a RadUpload control that I am using on a page in Sitefinity. Whenever I select a file to upload and submit the form, the ProgressArea appears, but the progress bar does not update, and the remaining time is a really huge number. Then the page posts back, resulting the the progress of the upload never being shown (it stays at 0%, even for large files). I searched around and found some similar issues online, but none of the solutions fixed my problem. I tried switching to a RadAsyncUpload control and changing my web.config runAllManagedModulesForAllRequests value to "true", but neither worked. I also tried a Telerik sample project with a RadUpload control that I found in another support thread, but that also displayed the same issue (but it works on the example page in the Telerik documentation). Might this be an issue with my DLL? I am using Telerik.Web.UI v2012.1.215.40 (Runtime v4.0.30319).

Thanks in advance for any assistance you can offer!

How to rebind more three RadGrid after close the RadWindow

Hi,

I am getting problem in rebind radgrid on radwindow close because i have to rebind 3 grid on parent page. It is rebinding just last grid which i have mentioned in code.

Following code i have used in my code

///------ In radwindow javascript code -------
function clientClose(arg) {
                getRadWindow().close(arg);
                var oWin = getRadWindow();
                var parentWindow = oWin.BrowserWindow;
                // top.location.href = top.location.href;
                parentWindow.refreshGrid();
            }

/// ---------In parent page javascirpt code -----
        function refreshGrid() {
                var masterTable1 = $find("<%=rgDefinition.ClientID%>").get_masterTableView();
                var masterTable2 = $find("<%=rgDevelopment.ClientID%>").get_masterTableView();
                  var masterTable3 = $find("<%=rgTesting.ClientID%>").get_masterTableView();
               masterTable1.rebind();
               masterTable2.rebind();
   masterTable3.rebind();
            }

Problem is that ----   this code rebinding my last grid means masterTable3.rebind(); because it is in the last of code.
