Hello,

it seems that the ComboBox isn't working with IE9 if HTTPS is used. With FireFox or Chrome everything works fine.
Create an selfsigend certificate in IIS (https://localhost/TelerikAjaxTest/) and enter a value in the combobox. nothing is happen.
Is there any solution for this issue?

aspx:

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

<telerik:RadComboBox ID="testCombo" runat="server" ShowToggleImage="false" EnableLoadOnDemand="true" Width="200px" AllowCustomText="false" AppendDataBoundItems="true">

<Items>

<telerik:RadComboBoxItem Text="Eingabe zur Suche..." Selected="true" Font-Italic="true" ForeColor="Silver" />

</Items>

<WebServiceSettings Path="~/Services/AgentService.svc" Method="GetAgents" />

</telerik:RadComboBox>

</div>

</form>

</body>

AgentService:

[ServiceContract( Namespace = "http://TelerikAjaxTest/AgentService" )]

[AspNetCompatibilityRequirements( RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed )]

public class AgentService

{

[OperationContract]

public RadComboBoxData GetAgents( RadComboBoxContext context )

{

List<RadComboBoxItemData> list = new List<RadComboBoxItemData>()

{

new RadComboBoxItemData { Text = "Value1", Value = "Value1" },

new RadComboBoxItemData { Text = "Value2", Value = "Value2" },

new RadComboBoxItemData { Text = "Value3", Value = "Value3" },

new RadComboBoxItemData { Text = "Value4", Value = "Value4" },

new RadComboBoxItemData { Text = "Value5", Value = "Value5" }

};

RadComboBoxData result = new RadComboBoxData();

result.Items = list.ToArray();

// http://www.telerik.com/community/forums/aspnet-ajax/combobox/fix-items-loaded-on-demand-can-be-added-multiple-times-on-scroll-q3-2009-issue.aspx

result.EndOfItems = true;

return result;

}

web.config

<system.serviceModel>

<behaviors>

<endpointBehaviors>

<behavior name="aspNetAjaxBehavior">

<enableWebScript/>

</behavior>

</endpointBehaviors>

RadUpload ProgressArea Bugs

First bug:
If your request exceeds maxRequestLength, RadProgressArea does not show up at all..

Making this example code useless:
http://www.telerik.com/help/aspnet-ajax/upload-how-to-client-file-size.html

And since all requests are completed either way i'm not inclined to increase my httpRuntime maxRequestLength any further.

And i'm not sure i would want to let users "cancel" their uploads when they are not really being cancelled, but lingering and consuming bandwidth.

Second bug:
If you should decide to display the cancel button, you'll notice that any subsequent attempt at uploading leaves the ProgressArea at a fixed position of where it was last cancelled.

RadDock with MasterPage and User Control

Hi,

I am new to use RadDock and doing a page similar to the one that looks like iGoogle where we can add gadgets to the page dynamically and realign, edit, close added docks with in one main dashboard (I am calling with that name) page. Each gadget chosen from the list will get loaded into the RadDockZone which there after can be realigned, refreshed by changing drop down and clicking on a button. My requirement is when the ascx control loaded into the dock is submitted (postback) the remaining widgets should not be refreshed or reloaded.

The current page architecture is like,
1. I have a master page within which some banner (header and few links like settings, signout) and footer (some information and few navigation links) will be present.
2. I have an .aspx page (inside master page) where sliding page with few buttons (called as Gadgets that are dynamically loaded like flickr, twitter, horoscope etc.,), RadDockLayout with 3 RadDockZone(s) inside layout is present.
3. I have a .ascx user controls for each gadget that will interact with the web service (hosted some where) and has its own layout that gets generated with the web service data.

Issue:
When I add the gadget to the page (Default.aspx present in Master.Master), the appropriate user control is getting loaded within the assigned RadDockZone by executing the Page_Load (with IsPostBack as true for the first time).
After getting the RadDockZone loaded with gadget selected, the first time drag drop of control (widgets/.ascx page) will not work as the moved gadget will be automatically placed into the source RadDockZone (from where we moved the dock).
Another issue is, if you change the selected index to something else within the raddock (SelectedIndexChanged for dropdown with AutoPostBack=true), data is loaded again and selected index will mark to 0. This is because for user control Page_Load is happening with IsPostBack as true.

Please help!!!

Thanks,
J

Validation and InvalidState

I'm trying to find the proper way to deal with Validation, either using RequiredFieldValidator, RegularExpressionValidator, or a CustomValidator. When one of these validators hooked up to a Telerik RadInput control fails, I'd like the control to switch to it's Invalid State, showing the warning, etc. I can't find anyway to do this.

[EDIT]

I've managed to figure out how to use RadInputManager to validate some of my textboxes... except that it doesn't seem to be invoked during Page.Validate(group), even if I set a group on the TextSetting. It seems like the TextSetting isn't actually added to the Control hierarchy, and so is never located. It also only has a single ErrorMessage property, which makes it impossible to actually specify different message for different inputs, even if their behaviors are the same: First name is required, last name is required, foo is required, blah is required, etc.

So other than setting the Invalid state of the controls... I can't figure out how this makes things EASIER?

Odd Dynamic Script being inserted into page...

When using a WebService-populated menu, as items get added, or branches opened (I can't work out the exact trigger). I get new dynamic script entries being put into the page - the script is simply :

' ' ;

In case that doesnt come out - its two single quotes, and a semi colon.

Its not that much of a worry - but when the menu is cached fully - there could be hundreds of these entries...

How to change the background color of a node, when the colors are applied in CSS?

I'm setting the background colors of the nodes in my treeview by binding to a CSS field in my database.

In my actual application, the nodes on the tree represent tasks and the colors indicate the priority. The same webform includes some controls to update the task. At the end of this process, I need to update the selected node color. Can someone tell me the code that I need to do this?

Here's a simplified code sample. When I try setting the node colors in code, only the text portion of the node is set. In the screen shot shown that's attached to this thread, notice how only the Node 1-1 section is colored in red. The rest of the node remains green.

What code do I need to change the color of the entire node?

Many thanks,
Tim

Postback javascript error: Two components with the same id...

Since release of Q3 2011 (2011.3.1115) javascript error occurred after postback in aspx page with TagCloud component (no matter ajax request or not).

Error: Sys.InvalidOperationException: Two components with the same id 'ctl00_ContentPlaceHolder1_MessageBoard_Cloud_Cloud_0_8' can't be added to the application.

Where control id is actually id of RadTagCloudItem() added during Page_Load and not modified on postback.

In previous releases (Q2 2011) everything was Ok.
