Performance Issues when using readonly checkbox columns

Hi

The grid seems to slow down alot when I have a few checkbox columns and I display the grid fullscreen. I've testing by removing and adding columns using the column chooser, and the grid is only slow when the check box columns are present.

I am binding a a generic list to the grid.

I am doing the following when initially creating the grid (setting the columns to readonly), and removing this code does improve that responsiveness

For Each col As GridViewColumn In grdProdArea.MasterGridViewTemplate.Columns

col.ReadOnly = True

problems with panelbar and EnableHostControlMode

to a shaped form, i added a panelbar with a few groupelements. i toggled one of the groupelements to EnableHostControlMode.

initially i was able to add a treeview to the groupelement in question; however, when i ran the app it flickered really bad and then crashed after i tried to collapse the groupelement.

now it's to the point to where i can't even toggle the groupelement to EnableHostControlMode without crashing the VS IDE.

ultimately, i want to add treeviews to groupelements and have no flickring.

thanks....

ScreenTips problem

If you access the ScreenTips in the Designer for any item in the RibbonBar and then change your mind and cancel out you will find ScreenTip code artifacts still left in the designer code section for the form

Embed Custom Controls

Hello,

After reading the documentation I noticed that there is support to bind columns to particular data/control types, but I was wondering if it were possible to bind a column/row to a custom user control that I have built that is comprised of various other controls.

Is this possible?

Thanks!

RadListBox Query

I have a problem after:-

1) I assign an Imagelist to a RadListBox (16x16 png)
2) I dynamically add items and assign the appropriate image from the Imagelist.

... when run, the icon overlays the text (no margin for the text).

Please can you tell me what I have missed doing?

Regards,

RanPanel feature suggestions

As I start to work with some of the other controls I am seeing some places where some features might be nice. Right off the bat I have a few suggestions for the RadPanel

1. Gradient Colors
2. Vista Areo/Glass colors
3. Rounded corners
4. Drop Shadow

A sub panel of this could also be a CaptionBarPanel

- same as the above suggestions but with a CaptionBar at the top of the panel. Options for the CaptionBar suggestions

1. Vista/Glass color option
2. Image / Icon support

just a couple of ideas to while away the morning with :)

RadTreeView

Hello,

I downloaded the SP1 for WinForm controls and was under the belief that the Treeview would support making a tree node visible at runtime. I can select the node, programmatically, but want to make it visible within the tree, for example EnsureFocus on the tree node?

So if the node is at the bottom, which the user cannot see I want the node to be in focus. Something like Treeview.Nodes[name].EnsureFocus

Is this possible and if so how?

Thanks
