Hi,

I am working with VS 2008 with ASP.NET AJAX Q1 2010 ListBox control.

Code in my ASPX page

C# Code to load Source RadListBox

C# Code to Save values from Destination RadListBox

The code for loading up the Source RadListBox works fine and I have all the users correctly and I am able to transfer them using the buttons over to the Destination RadListBox.  The problem is when I click on the SAVE button and want to grab the DataValueField and the position of each item in the Destination RadListBox and store it in the database, I have no values.

Aloha!

I'm currently working with the Q3 2009 version of the ASP.NET controls and seem to have hit an oddity with the RadDatePicker (and probably other) controls when setting the EmptyMessage and performing optional field validation.  I've set the EmptyMessage on the control and also have a RangeValidator applied to it; validators don't typically validate empty text and this is fine on the client validation (no error) but server-side fails as the ValidationDate is set to the EmptyMessage value, causing the RangeValidator to try and validate.

Is there a way around this, short of making code changes and performing custom validation, enabling/disabling validators etc?  Or should I just remove the EmptyMessage value?  I've read a couple of other threads here discussing always catching the (possibly invalid) data entered in ValidationDate but in this case, there is no explicit data entry.

Thanks in advance.

Hello,

we´ve been using RadControls for more than one year now. But since version 4.x of RadChart we have problems with ChartSeries Labels.
In case of IntelligentLabelsEnabled="false" all labels are shown, but overwrite each other and do not look very well positioned. If IntelligentLabelsEnabled is set to true, it looks much better, but some labels just disappear or overwrite each other, too.

We now use RadControls for ASP.NET AJAX 2008 1 619.

Here is some code to reproduce the problem:

There may be some properties to change the look of labels, we do not know by now. The documentation in some cases is still very rare ;-)
Hope u can help.

Thanx,

P.S.: While writing this forum post, I pasted some content into this editor window. An askbox occured, asking me if I want to allow pasting into this window (In German: Möchten Sie zulassen, dass Informationen aus der Zwischenablage in diese Seite eingefügt werden?). If I said "No" the pasted content anyhow sometimes appeared, but appeared everytime when I pasted twice (and answered "No").

Hi, i am facing a problem in RadScheduler :

My coding is as below   :
Attach here is the output of my coding:

I am attempting to use the RadSpell control for validating passwords selected by users.  I want to make sure the password selected by the user is not in the dictionary (in addition to other validations I am also performing).

How do I fire up RadSpell on the server-side, pass a word into it, and return whether the word is in the dictionary or not?

Can someone provide a function that does that?

Thanks in advance!

The graphic shown when the loading panel is in 'wait' mode has changed from the 2009 release - it seems that the background square is no longer transparent. Is there anyway to get the 'old' one back?

Hi,
I have a problem with the load time of the scheduler.
On my pc with IIS and local SQL server database it takes 20 s to load. I am sure this is going to double or triple when going live with remote web servers and databses.

In this application I am using scheduler with master pages and the load time is very critical. I have tried the following to try to optimize the time on the usage of the scheduler
1. filter appointments in the stored procedures for only what is shown on the screen, as per the day, week, month...view
2. used a rad windwow to reduce the HTML codes on the rad scheduler. This not using the Edit and Insert apointment inbuilt panels...

These 2 solutions have helped  a lot but I am unable to optimize the time whn the application first loads.

My question are:
1. Is there general way to optimize the load time of schduler..e.g..best practices..etc?
2. Are there any known issues that affect the load time of the rad scheduler when used with master pages?

Thanks for your reply,

I have a problem using the RadTreeView which i can't figure out.

I want to create a treeview and load the content runtime as it changes depending on a selection made from a DropDownList.

I have no problem by loading the content, the problem is the styleing which i can't figure out how to control when loading the content runtime.

My HTML looks like this

My Code Behind looks like this

My Screen looks like see this link http://screencast.com/t/MDYxNTU5MzY

as yo can see from the screenshot i can't see the childnodes. When clicking on the Parent node the child nodes is rendered to the right. How do i force the childnodes to be rendered to the left ?

also how can i change the styling when adding content at runtime ?

thanks for your help
