This is how it goes:
I added a vertical scroll bar on a panel which is panel1 and inside panel1 I also Added another panel which is panel2.
The height of panel2 is bigger than panel1, this is where vscrollbar comes in...I already added the code for vscrollbar so that it will change the location of panel2 inside panel1.
The auto size function of panel2 is set to true so that it will automatically grow to fit the controls that i put inside it, which is why panel2 is bigger than panel1. How can I set the maximum property of vscrollbar depending on the height of panel2, I already have an idea of getting the height of panel2 and manipulate the numbers and add it to the maximum property of vscrollbar, the problem is I dont know how to do it.....I know other people will tell me why not just set the auto scroll property of panel1 to true... I already know about that too...I just want learning experience and for other future purposes...I'm a beginner and still learning
Handle the SizeChanged event of the Panel, get its Height property, process as required and assign the result to the Maximum of the VScrollBar. Similarly for the Width and Maximum of an HScrollBar.

I have 2 panels on windows form and both occupied the equal portion on form (i.e. 50%- 50%). Once i run the application, I want to resize the panel size by dragging form with mouse (i.e. 25%-75%). The portion given is not fixed it can be in any size. I just want to resize the panel by dragging/streching mouse.
Please help to resolve the issue.
Thanks,

I think you want to use a SplitContainer control on your form. Put the Panel controls into the two different containers of the SplitContainer, and set their Dock property to Fill. You can set the SplitContainer to Dock.Fill too or set the Anchor properties such that the SplitContainer stretches along with the form.
I have a Winform and there are few controls in It, At Top there is a panel and inside it there is a label control with Dock Property Fill, I have to populate dynamic text into that label control, Sometimes text is so bigger that it cannot been seen,
How to add Scroll or size increase of Panel and then Form in this scenario?
I have enabled , AutoEllipses and also Enables the AutoScroll Property of Panel.
Put the Label in a Panel that is AutoScroll, then set width of MaximumSize of Label, then set the label to be AutoSize.
You should set width of MaximumSize enough less than panel to only vertical scroll bar be visible.
I seem to have a lot of trouble getting a SplitContainer adjusted the way I like it. I have the following form called frmMain:
In the form Load code I have to following code:
With MainContainer
.IsSplitterFixed = True
.Dock = DockStyle.Fill
.SplitterDistance = 200
.FixedPanel = FixedPanel.Panel1
.Panel1.BackgroundImage = Resources.My.Resources.ResourceFile._001
.Panel2.BackColor = Color.White
.Panel2.AutoScroll = True
End With
When I run the code I get the following:
I want to remove the gray splitter since there is no use to it. Is this a common beauty
bug and is it possible to remove it?
My second problem with the SplitContainer is if I resize my window, the backgroundImage in Panel1 and the white color in Panel2 don't adjust with the window. I searched high and low to the Resize code but I can't find it. The Panel2 has User Controls, eg. Dashboard and are loaded this way: MainContainer.Panel2.Controls.Add(Dashboard).
Is it also possible that Panel2 automatically adjusts to the weidht of the window so thay you only have a hortizontal scrollbar?
Thank you for reading my question and hopefully you can help me solve my problems with the SplitContainer. Have a nice day.

If you don't want the user to see or move the splitter, why use a split container? As an alternative, consider using a TableLayoutPanel configured with 1 row and 2 columns. The first column would be an absolute 200 px wide while the second column would be set to 100% wide. In each of the two cells, you could place a panel which is docked and set to have a margin of 0,0,0,0.

While I did not mock up your current solution, I was not able to replicate these problems with a quick mock up of the solution I proposed above. With regards to auto-scrolling, the only reason that scroll bars should appear would be if a control is off the edge of the screen or the available screen space is less than the minimum size of the panel.
You have 2 options:
Use TableLayoutPanel (as #erdomke suggests)
Use 2 Panel controls
For 2 panel controls, dock panel1 to Left, and dock panel2 to Fill. To fill panel2 with a UserControl that resizes, set it's Dock property also to Fill.
How do you set the maximum range for the horizontal and vertical scrollbar in a panel
in VB.NET 2008 ?
Set the AutoScroll property for the Panel to True. That ensures that the Panel automatically adjusts the scrollbars to keep all controls inside the panel viewable. You can override this behavior, in case you don't use controls or want a margin on the far end, by setting the AutoScrollMinSize property.
Sometimes, I have a picturebox lets say 100x100. But the image it will display is actually 100x400.
I don't want to increase the size of the picturebox itself. Instead, I would like to create a vertical scrollbar (or horizontal if needed).
I could not find a scrollbar in the toolbox, so I guess I have to code it. But, how?
And I still wonder if I didn't make a mistake and didn't see the scrollbar in the toolbox. My apologies then :(
I suppose you could add separate scrollbar controls and sync their Scroll events up with the offset at which the picture in the PictureBox is drawn, but that sounds like actual work. There's a better way.
Add a Panel control to your form, and set its AutoScroll property to "True". This will cause the control to automatically show scrollbars when it contains content that lies outside of its currently visible bounds. The .NET Framework will take care of everything for you under the covers, without you having to write a single line of code.
Drag and drop your PictureBox control inside of the Panel control that you just added. The Panel control will then detect that one of its child controls is larger than its visible area and show scrollbars, thanks to the AutoScroll property. When the user moves the scrollbars, the portion of the image in your PictureBox that is visible will be automatically adjusted. Magic.
(The reason you have to use a Panel control as a container is because PictureBox does not inherit directly from the ScrollableControl base class, which is what provides the AutoScroll property.)
I tried this and it worked well. But I noted that if the picturebox is docked in the panel, the picturebox is automatically set to the size of the parent panel, and can't be set larger (at least not in any way I could find). This defeats the purpose of the technique. So -- put the picturebox on the panel, but don't dock it, and it will work perfectly.
There are no automatic scroll bars on a picture box, but you can add the VScrollBar (and HScrollBar) control to the form and handle the image scrolling manually by redrawing it at a different offset each time the Scroll event is fired.
