I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?
Where in VS2010 can I find a horizontal separator control, as can be found in Outlook settings (screenshots below)?[URL]..

I have to design a custom "log grid" control to use in another of my projects.Up front, I am new to vb.net 2008. I have used VB6 for years and I am trying to learn how to resove the differences as I go. But I need help.
This log grid contains 96 columns and 4 rows.I tried using the TableLayoutPanel and a Panel per cell but found the control to slow to paint. That's 384 discreet controls.I am now trying a usercontrol with a panel and GDI+ to create the grid. I've created a collection for the columns and a collection for the rows. So far so good. My mouse clicks raise the correct events per cell.
I now need to indicate which column the mouse is over. This is the problem. The column must be highlighted by a vertical bar from the top of the column to the bottom. It must also be transparent. I need to see the gridlines under the highlight. I've tried using region using the following code. (myRegion is declared Private MyRegion as Region at module level for persistance)

I have a main form that contains a vertical SplitContainer.Inside the SplitContainer's left panel, I have a TreeView control.Inside the SplitContainer's right panel, I have another SplitContainer (this one horizontal). This container is fixed, with headings above the split and a Panel control below it.I dynamically load my own user controls into the Panel control whenever the tree view changes.
Most of the user controls that are dynamically loaded have a DataGridView that should receive focus when the control is initialized. Sometimes this grid is on the UserControl surface directly; sometimes it's in a GroupBox; etc.What is the best way to programmatically set focus on the DataGridView control, given that it may placed within a variable number of control containers? I've tried the obvious - .Select, .Focus, .ActiveControl, etc. None of these seem to work - the TreeView item that I selected is still highlighted, and even though a record is selected in the DataGridView, it doesn't have focus.
Here's the code where I add the user control within the main form:
Private Sub LoadRightPanel(ByVal section As String, ByVal moduleName As String)
Heading.Text = String.Empty
SuspendLayout()
RightPanel.Controls.Clear()

I've been working for several days on a GUI where a lot of individual data elements need to be displayed side-by-side and wrap to the next line when they overflow; the goal is to not have to explicitly design an individual 'row' element with a set number of elements for this purpose. The FlowLayoutPanel seems great, except...
I need to be able to determine how many elements are on each line (dividing the width of the control by a predetermined value indicating width of child controls does not work); I need to be able to determine how many elements will be on each line (I may need to put 4 elements on line 1, then auto-wrap, then 8 elements on line 2, then auto-wrap, then as many elements as can fit on line 3 before autowrap, then 16 elements on line 4, etc); and finally I'd really like to put a 'line header' at the left margin and a 'line footer' at the right margin, where for example the line header contains a line number and the line footer contains the number of elements on that line.
In my project i added a User Control so that i can reuse in different Windows forms.I designed and coded the UserControl1 according to my need and now i want to use it in Form2 but i cant understand how to do it?

if I enter 'A' in the combobox1 then combobox1 leave event will fire twice any other entry is Ok since the next control to get focus is button2 (in the normal tab order).It seems that if I try to skip the next control (based on the tab order set for the form), the leave event fires twice.

I have a program that I am creating in a windows form to track information about computers that I build for each project I do. The way I have my form layout is two buttons on the top of the form(1 for adding a computer and the 2nd to remove a computer) I then have a Tab window where when I want to add a computer I use the "Add button" click event to create a new tab and add a user control "Computer" that I created that contains all of the default fields that I desire (i.e. serial numbers os type, product key etc.) The "Computer" user control also contains two buttons (1 for adding a PC Card and the 2nd to remove a PC Card) The PC Card is another user control that I have created that has all of the desired fields I require for PC Cards. I am able to add new computers with no problem and name the tab

I am using Visual Basic Express 2005. I am opening the startup form of my application in "Maximized" view. In the form designer, I am setting the anchor properties of the various controls that I have on the form so that they are located where I want them to be located when the Form loads.
I was wondering, if there was a way such that the form in my designer would be of the same size as the Maximized form? As of now I am dragging and resizing the edges of the Form in the Designer view to make it bigger..
In C# Windows Forms, a user control's InitializeComponent is called from the form's/control's constructor. When I create same scenario in VB.NET I don't get a constructor, and I can't locate a place where InitializeComponent is called.I need to call my code between InitializeComponent and when the control's Load event is raised, preferably still in the control's constructor. How do I do this in VB.NET?

I am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel
disabling the context menu for webbrowser control in Windows forms using c#.
View 2 RepliesI'm not sure that I'm doing the right thing here..I'm writing a user control that's supposed to be (fairly) generic. It's a bit like a modified email client specifically tailored to some of the internal things we do.
The view is composed of two main pieces, a message list and a viewer. I need this viewer to be interchangeable, so if someone wants a different style of view they can simply handle an event and change a property. My original idea was to just have an INoteViewer, but since I'm adding it to my form I also need to guarantee that this object is a Windows.Forms.Control of some sort.
Should I continue along these lines and maybe raise an ArgumentException if I can't cast it to INoteViewer, or should I go a different direction and create a class that inherits from Windows.Forms.Control?
