Text versus SelectedValue

Hi,
Can you explain the correct usage of the RadMultiColumnComboBox SelectedValue and Text properties. It seems that they are not always in sync. For example when the DataSource is set, the SelectedIndex == 0, SelectedValue == value of Item[0], but the Text property == "".

I'm trying to determine when I should (or could) use the Text property. If I use it to "set" the Text property does the SelectedIndex/Item/Value also get set?

What event causes the Text property to be set? Is it after an event is finished?

Thanks,
Mike

RadScheduler Navigation Calendar Not Working

Hello,

I've used the Rad Scheduler for a while now the navigation popup calendar is not causing the date of the scheduler to change. I believe this began shortly after changing to the 2009Q3 release.

Anything you can do to help is greatly appreciated.

Key Points:
1. Data Binding: The data is bound to the scheduler on the server side code where data is retrieved from the database and looped through to create a list<appointment> of appointment objects.
2. Navigation Arrows: These were not working either, but after we made the setting of the startdate, enddate, and timezone offset be in an If(!IsPostback) block, the arrows now work (not the calendar)
3. The control has been placed on a page with no other controls and the problem persists

Below is the client code:

    
            <pro:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"> 
        
                <AjaxSettings>

serious issue radform com visibility

hi,

i am opening google maps in a browser control in radform. for this i need to to set com visibilty to true to communicate with javascript in locally hosted web page.

my code :

using System.Runtime.InteropServices;

using System.Security.Permissions;

// Make COM Visible to communication with other App

[ComVisibleAttribute(true)]

// Set Security Level to Full Trust inorder to enable external Javascript function invokes and data passing

[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]

works perfect in simple .net forms

but gives error in rad form....

error:

A QueryInterface call was made requesting the default IDispatch interface of COM visible managed class 'TcpMappingServer.LivePlayAVL'. However since this class does not have an explicit default interface and derives from non COM visible class 'Telerik.WinControls.UI.RadForm', the QueryInterface call will fail. This is done to prevent the non COM visible base class from being constrained by the COM versioning rules.

Anysolution Please, ineed it quickly, if radform wont work will the shaped form work...

or any other solution with radform.

thanks in advance!!!

RadItem Collection Editor

I'm using the RadItem Collection editor to add items to my combobox. I see a place to enter the display text but where can I enter a value that I can use within c#? I'm trying to use my combobox's SelectedValue property but it comes back as null. Why would selectedtext come back as "" when it has been selected?

Thank You

DateTimePicker -- arbitrary text entry?

It doesn't appear the DateTimePicker allows abitrarily entering text into it, but rather, it only functions as a picker. Any way that in the future it could include functionality to arbitrarily enter a date? Reasoning would be that if you are trying to pick a date WAY in the past, there is no easy way to get to it... you have to scroll through the months at maximum 6 at a time (3 before the current month, 3 after) which would take forever.

Being able to enter arbitrary text as well as having the "quick month" selector let you also quickly select a different year would help solve that problem. In other words, it should work similar to the ASP.NET RadCalendar (DatePicker mode).
