Form with only 6 buttons takes "long" time to open

Hi there,

I am having the following problem: I have a form with 6 radButtons and 1 radLabel. The form takes a second or two to open. It's not much but still quite bad / disturbing for the users experience. Also, I'm on a somewhat powerful machine, so I worry about what users on slower machines is experiencing.

I made a form completely similar to the slow one, though without the radControls and it opens instantly. As soon as I add the 6 radbuttons and radlabel, it slows down. Final thing worth noting: When I have opened the slow form for the first time, and then closed it with me.close, and then try to open it again, the form appears almost instantly. It seems to me it could be some sort of initialization code that runs on the first time the controls are instantiated, maybe?

In that case, I'm hoping there is some way I could run this code before showing the form to the user. This way they will get a snappy experience, and not uninstall our app because of small annoyances like this :)

Thanks for any help!

upgrade questions

In the documentation one of the points was to Remove all Telerik WinForms assemblies from the GAC. Can you give me instructions as to how to do this? I have already removed the earlier version of WinForms.

RadMultiColumnComboBox help

Hi,

is there any tutorial or help available for this control? I know it is new, but it's very hard to work with without proper documentation/training material. I've looked on online help, but there is only brief class/members enumeration. Thx for any help.

Radchart Click event stopped firing

In my app(VISUAL BASIC .NET), when the user clicked on a radchart, the radchart click event was firing OK.

All of a sudden it just isn't firing anymore.Stopped !!!

I tried deleting the radchart and puuting a new one in, nothing happened.

However if a i start making a new app and put a radchart in it, it works normally.

Is there any clue to what is happening all of a sudden ?

Thanks

P.S. It seems that all events for radchart do not fire !!!
If i put it in a new app it works.In this app, NO !!!

Chart (obsolete as of Q1 2013)
