Bug in Q2 2010 SP2 in “Folder Tree” mode.

[Raymond]

Hi!

1. Run demo application from "RadControls for WinForms Q2 2010 SP2"
2. Select GridView -> Hierarchy -> Folder Tree
3. Expand “Program Files” folder – everything is ok.
4. Expand “My Documents” folder - ok.
5. Collapse “Program Files” folder – folder is collapsed but icon on “My Documents” folder is changed from “-“to “+”! It might be very misleading to the user.

 

Is there any workaround?

Regards

Hello Raymond,

It's not just that, the + / - signs are fluctuating wildly if you start playing with it for some time, but I'm guessing it's just a problem with the display image, i will try to take a look at it when i have some spare time and i will get back to you.

I am looking forward on response from you because I used this control in my application and now I have problem with this +/-….

It is not problem only with displaying image +/- please take a look on this.

To scenario that is sent in my first post I can add next point:

 6. “My Documents” is expanded and has image “+” but when I click on “+” folder is not collapsed.

Hello again Raymond,

Sorry, but from what i see there is a visual / expanded item bug in the Folder Tree, a more simple example that something is wrong is just to expand all the parent nodes, and then scroll up and down, you will see that the expand / collapse images are fluctuating, i would suggest submitting a support ticket, and wait for a fix.

By the way, not even the ChildViewExpanding event is firing when this "glitch" occurs...

If there will be no answer on this problem from Telerik soon, i will take a deeper look to see if there is any possible workaround.

how can I submit support ticket?

Hello,

You can send a support ticket (http://www.telerik.com/account/support-tickets/new-support-ticket.aspx) (with a sample application would be best) but in this case it could easily be checked, although i have to mention that i think that the problem lies with the Hierarchy because the images for the cells (the expanded folder and the closed folder) show up ok but the row expand / collapse are getting scrambled.
