I'm workin on a windows application and using dock panal. I have button and images under dock panel and firing button_click, images_click events. It opens the new window form. In windows-Vista, the functinaolity is running as I want. But when I installed the application in windows-XP, the events don't fire. Application hangs up. Any body has any idea?

We've opened a support ticket with a response time for 24hrs, we even provided a sample project, but we are getting no response from telerik after more than 48hrs.

The chart is meant to display two line graphs indicating a sales comparison between different months.

The problem is, when we compare Janurary and March, there is no error, but when we compare either Janurary or March against Feburary, a 'series.Index' nullreference error is thrown. There are 31 entries for the xaxis, all the entries have a number assigned (including Feburary, where 30, 31 has values '0'). There are some instances that the graph is displayed correctly, without any modification in code and in the numbers, but most of the time it crashes the application. It's an irregular crash that we cannot pin point what the problem is.

Since the sales are displayed in Japanese yen, the profit number is as high as 100,000 - 200,000. We are not sure, but is the chart having problems handling large numbers?

Does anyone else have a similar experience? Moreover, our subscription is about to run out in a few days, but hopefully they will provide us with a version of RadChart that does not crash irregularly, instead of asking us to renew the subscription to get the component that actually works.

Hi Telerik,

   can you send me TelerikExamplesBlack Theme (xml file) for RadTitlteBar.

  as in your sample demo Example  
   ExampleCS -> GridView -> Form1 ->RadTitleBar Theme
 
 i didnt found the related Theme Xml file,
 and when opened this theme (in Design view ) in style builder, it opened some other titlebar theme but not TelerikExamplesBlack.
  
   i need to add this theme to my project.
 
 i am using WinForms Q1 2008 BETA, Window XP SP2, VS 2005.
 
Thanks,
Santosh Kumar

I have a button on my form where the text = "Assign Checked Customers"
The button is set to a DisplayStyle of Text and the TextAlignment is set to MiddleCenter.  The text is absolutely not centered and the only way for me to get it centered is to set the leftmost number in the Padding property to 10.  This will do but it's highly irritating.  I've also noticed that as I decrease the size of that button, it appears to need a lot of padding space on the left and right side of the text or it chops off the right side of the button completely.  This makes it impossible to create a button barely any wider than the text it contains.

I've also noticed alignment problems in with the RadLabel control.  For example, drop a RadGridView and a RadLabel directly under it on a form.  Leave the RadLabel's default text as is. E.g. "Label3" and align the left side with the left side of the RadGridView.  Leave the AutoSize property on the RadLabel set to True.  Now change the font weight to bold.  Notice that the text is cut off which to me means AutoSize isn't working properly.  Now set AutoSize to False.  The left alignment will be wrong when the font weight is bold and you will not be able to snap the left alignment to match the left border of the RadGridView.  For sake of comparison, drop a Microsoft label underneath the RadLabel and do the same things to it.  The Microsoft control operates as expected.

Are the problems I state above known problems?  I'm new to the Telerik controls but I certainly did not expect such basic things to not work properly.

This isn't a real game ender - just something to note.

If you pick a font in the style builder that doesn't have a 'normal' setting (like a bold-only font) the VSB will crash. Easy to reproduce - try modifying the font of a control, then use the down-arrow to cycle through all the fonts on your system.

Can anyone help with RadDateTimePicker and times ?

I am having a lot of issues with the RadDateTimePicker when trying to deal with Times.

It does not seem to work at all when I have ShowUpDown = true
The best settings I have found to work have been
      Format = Long
     CustomFormat = HH:mm:ss
     ShowUpDown = true

But even this setting seems to have some issues when trying to change time from
from 1:30:45 to 23:12:45 programtically.

I would like to just Bind a DateTime to the control
    radDateTimePicker1.DataBindings.Add("Value", controller, "EffectiveTime");
This seems to work when dealing with date formats but not when the settings are
      Format = Time or CustomFormat = HH:mm:ss

Can you please let me know if this control can successfully be bound with a time format.

Thanks.

Hi,

I am new to RadControls.

In my code base, I have created a tabstrips and an "Add Tab" button. 
I have also set scroll property of Tabstrip to allow scrolling.

On click of the "Add Tab" button I programmatically add a new tab item to the tabstrip and select it. However, I cannot get focus on the newly added tab.
If the count of tabs grows, I need to scroll to the added tab.

Is there some way by which at the time of selecting a tab I also set focus on it?

Any help shall be appreciated.

Thanks in anticipation,

Era

Hi,

with radcombo the same problem as describe here with radlistbox:
http://www.telerik.com/community/forums/thread/b311D-bchmke.aspx

I use a forms.combobox and bind it to a List<MyClass>.
Then I set DisplayMember to the name of a porperty.

In the selectedindexchanged I do:
MyClass selEle=combobox.SelectedValue as MyClass;

And (as expected) I get an object assigned if there is a selected item in the CB.

But always null with RADCombobox


Regards

Manfred
