View 1 RepliesI've dynamically added 20 pictureboxes to a panel and would like to see the panel scroll when I use the mouse wheel. To implement this I have tried to set the autoscroll to true on the panel control. Here is the code.
For i As Integer = 1 To 20:
Dim b As New PictureBox()
b.Image = Nothing
[Code]....
It works for "button" control, but not for the "picturebox" or "label" controls?
How can I implementthe scrolling affect using 'mousewheel'?
I have a usercontrol I created. I added a panel and a vertical scrollbar to the right of it. I'd like to be able to scroll it with the mousewheel. The problem is there doesn't seem to be any events that fire on mousewheel. If I take the panel off then the usercontrol has focus and it will fire on mousewheel in the form. But with the panel on it doesn't seem to fire the mousewheel event of the panel, or the usercontrol within the control or even on the form. The best solution would be to have an event fire in the usercontrol but I'd even accept an event on the form and feed it back into the usercontrol.
I'm using vb.net and vs2005 if it matters.

View 4 RepliesI am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.

I have set the panel to autoscroll and added scroll bars but they do not scroll far enough... They only scroll about 2cm.
This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.

Is there a way to hide the scroll bars on a VB.Net panel? We have written code to allow the user to scroll using a touch screen and do not need to see the scroll bar. I know it has to be there for the scrolling to work, but would like to hide it from view.

View 2 Replieswhich populates a flow layout panel with a number of buttons. The number of buttons is completely dynamic (it's based on how many subfolders are in a given Directory.)What I want to be able to to is use two buttons to scroll up and down the panel, without the use of scrollbars.I've spent a good few hours looking around trying to find a solution (as well as messing around with the 'verticalscroll' properties of the panel with code, but with no success.

I have a picturebox inside a panel, the picturebox is long, and the panel is set to allow scrollbars, which it adds. I can scroll the picture at design and runtime, but how do you scroll it programmatically?
Starting with the picture box with the top set to 0, and then doing this... (using any non-zero value as the lY value)
Dim newLocation As New System.Drawing.Point(0, -lY)
[Code]....
So how do i get the value to change (e.g. to scroll the picturebox!)

View 1 RepliesI have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?

Is it OK to not call the Base sub in some cases?How do I find out if it is OK? (For example I don't imagine you'd want to not call it in New()Secondly and most important, What is going on? Why and I getting scrolling with the wheel in a Usercontrol and not getting it in other UserControls?
