I am currently using a DevExpress (10.2) Banded GridView within my Visual Studio 2010 project. It works great except I was have an area where I allow the user to choose which columns they want visible or invisible. I noticed that if I make all the columns within a band invisible the band still remains and gives an empty column in my grid. I was wondering if there is some way to automatically

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

View 2 RepliesSo I have a program that only has one form in it, this form is just an "About" window that appears when a specific context menu item is clicked from the system tray icon (NotifyIcon) that is on the form.
All I want to do is make it so that when the program is launched, the form is not displayed at all and just the system tray icon appears.
I have accomplished this by doing the following but just wondered if there is a better/easier way?
1. Set the Opacity of the form to 0 in the designer
2. Set the ShowInTaskBar property to False in the designer
3. Use a timer that is started in the form Load event to call Me.Hide after 1 second
Then when I want to show the form I just set the opacity back to full and call Me.Show
Is it possible to make tooltips invisible in VB.NET 2005? The reason that I ask is because I need to store some data about each node in a treeview control, but I am already using the node's tag value to store an object that represents a "SuperToolTip" which is a control in DevComponent's DotNetBar utility. So I do not want the tooltip to be visible, since I am already displaying a more feature rich tooltip for each node. I guess I could store an array in the tag, that would contain the object that I needed, as well as the string info I need for the node as well.

View 3 RepliesI put some group boxes on a user interface and now labels and pictures that are set to visible can't be seen even when the group box is set to visible = false. (I have the group box and the pictures and labels in the same place on the form and was planning on using buttons to make them visible and invisible but the pictures and labels stay invisible no matter what while being in the same place as the group box.)
