Hi,

I have two long-loading asp:panels on a page with lots of ajax controls interactions.

When the page load completes I add two ajax requests to the ajaxmanager queue so the user can interact with the page without being held up.

What I want to do is if the user interacts, make their ajax request 'jump the queue' and get processed before the two long-loading ajax requests are complete. Once the user's request is complete, continue with the queue.

Is this possible? I see ClientEvents-OnRequestStart can eventArgs.set_cancel(true), but this will also cancel the user's request so it won't work.

I have lots of controls on this page within grids, treeview, buttons, links, so it isn't practical to have all of these change to call a javascript function that eventArgs.set_cancel(true) and then raises an onclick() or similar.

Do you have a solution?

Thanks, Dan

Several folks here where I work have issues with content shifting around in Internet Explorer. I have examples of it happening when mousing over elements (like buttons) and when clicking on buttons. I've come up with an example project to show it happening.

Here's the .aspx:

And here's the codebehind

choose options in the two drop down lists and then click the button.  You'll see the entire page contents shift downward in IE but not in Firefox.

The actual example in my real code shifts when I mouse over the button..

thanks...

Is there a way to get the same functionality using code behind instead of clientside javascript.
For example the following code used in online demo .../liveDemos/Windows/Examples/RestrictionZone/Defaultcs.aspx
goes as follows:

function OnClientNodeClickingTreeview(sender, eventArgs)
{
var oManager = GetRadWindowManager();
//get the clicked node
var Url = eventArgs.get_node(sender, eventArgs).get_value();
//get the active RadWindow
var oWnd = GetRadWindowManager().getActiveWindow();
//now we need to open a new RadWindow and ensure that
//such RadWindow has not been already opened.
var windows = oManager.get_windows();
for (var i=0;i<windows.length;i++)
{
var wnd = windows[i];
//check if an already created window has that Url
if (wnd.get_navigateUrl() == Url)
{
//if so - activate that window
wnd.setActive(true);
return;
}
}
//else open a new window
radopen(Url,null);
}
I have been trying not to use javascript but instead to implement the above in codebehind. Where can I get info to assist me in the above endeavour?

I have downloaded the trial version of the RadControls for ASP.NET Ajax, and can't get the skins to work correctly.

In the web.config

<add key="Telerik.EnableEmbeddedSkins" value="false">
<add key="Telerik.Skin" value="HRP">

I have also created a "Skins" directory at the root of my app, and copied in the Default skin files from the Telerik directory.

I have created a sample test page that has:

RadScriptManager
RadFormDeocrator

Two RadTextboxes
Two RadComboboxes
Two DatePickers

I have set enableembeddedstyles to false, but yet In Firebug, I can clearly see that Webresources are still being downloaded.

Can you point me to a sure fire way to use a custom skin?  The embedded ones seem to keep getting in my way.

Thanks.
Bill.

Hi all,

In design time, binding to and object datasource returns a "ID could not be set to property DataFieldID". However, if I run the application it works fine.

I'm testing http://www.telerik.com/help/aspnet-ajax/menu_dataobjectdatasources.html

Any idea?
I'm using Q2.2009

Hi,

I am facing an interesting problem with Grid having Child Table and with Slider paging.
When I expand and collapse child row, after collapse the pager of child table still gets displayed.
I have attached screen shots for the reference.

Thanks,

Dear Telerik
                       I placed a radcombobox inside a radgrid.I have autopostback set to true. I am using a GridTemplateColumn inside that I have filtertemplate inside that I placed a radcombobox .I also have itemtemplate inside that I have a checkbox.The combobox is populated with three values attended,unattended and all.when I select unattended/all in radcombobox it is showing the selectedvalue as attended only after postback.If attended is selected in radcombobox then the check boxes appears as checked.If unattended is selected from radcombobox then the checkboxes appears as unchecked.Please let me know what is wrong here.urgent please...

Hi,

I found a blog with explanation and example of using RadcomboBox in MVC with LoadOnDemand.
I used the same version of Telerik.Web.UI and the same code but combo box on my page is totally disabled. RadComboBox in my case is placed in a partial view. I read somewhere that there is a problem with css styles if RadControls are placed in partial views but I couldn't find the solution to this.
However, when I placed it in a regular view page (non partial view) I got exception stating that control could not be modified inside server tags <%..%>. For that I found numerous solutions but none worked for me.
Do you have any suggestion of how to make ComboBox operational in partial view?
Do I maybe have to refer to all the JavaScript files needed for RadComboBox directly on the view page?

Thanks in advance.

Here's the sample of the partial view, if it means anything:
