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!)
I'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'?
My image is inside the panel, I set up a if-statement for the boundary which it can only be moved. When I tried to run it, it looks crappy when the mouse has panned it outside the boundary. Here is my code for panning:
If (mouse.Button = Windows.Forms.MouseButtons.Left) Then Dim mousePosNow As Point = mouse.Location Dim deltaX As Integer = mousePosNow.X - mouseDowns.X
In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?
I 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 am also using the following code to try and scroll whilst zoomed in
Inherits System.Windows.Forms.Form Private m_PanStartPoint As New Point Private Sub picbox_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PicBox.MouseDown 'Capture the initial point
[code]....
I have set the panel to autoscroll and added scroll bars but they do not scroll far enough... They only scroll about 2cm.
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.
I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.
I have a panel, which contaisn two Pictures.When the panel is mousehover the Pictures appears. When the panel is mouseleave the Pictures disappears.However, when I'm trying to pass the mouse between the Picturebox and Panel, the Picturebox disappears, because the panel doesn't detect that as panel area.
Private Sub Panel_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel.MouseHover Me.NextIMG.Visible = True Me.PrevIMG.Visible = True End Sub
Private Sub Panel_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel.MouseLeave Me.NextIMG.Visible = False Me.PrevIMG.Visible = False
I have a DataGridView with about 250 rows. I want to select a row programatically and scroll to it. Whatever I set FirstDisplayedScrollingRowIndex to the value is never greater than 2 and the required row is out of sight. I can manually scroll to the correct row.
iSelectedRow=136 gdgvTasks.CurrentCell = gdgvTasks.Rows(iSelectedRow).Cells(1) ' Method to set Current Row
I'm developing a WPF app in which I have a ScrollViewer with grid (16 ColumnDefinitions all auto width) with an image assigned to each column.The effect I want to create is when the mouse enters a area on the left of the ScrollViewer the images will scroll to the left and when the mouse enters an area on the right of the ScrollViewer they scroll to the right. The scrollbars will be hidden. The areas to the left and right are defined by two rectangles with mouseEnter and mouseLeave events. My code behind utilises a timer to programatically scroll the ScrollViewer leftor right.[code]
I am using a flowpanellayout. I want to scroll the panel, but not using the scrollbars. (We are going to use a touch screen). I am going to use button to scroll up and down. How can I control that?

I need to know how to programmatically scroll a form to the top position. I tried Refresh but that didn't do it for me. I'm looking through searches but haven't found what I need yet.
I am trying to control the horizontal scroll of a panel box in vb.net. The problem is that I can only seem to move it just a little bit using the following code:
Private Sub HScrollBar1_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles HScrollBar1.Scroll panSS.HorizontalScroll.Value = HScrollBar1.Value End Sub
I am having a tough time in vb.net to make the scrollbars to work of the contents of a panel.... here is my code
Private Sub HScrollBar1_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles HScrollBar1.Scroll Panel122.Left = HScrollBar1.Value
now, i want to change .Left to .Right, but it won't let me?
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.
which 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 two panels, and I want them to both scroll horizontally with one scroll bar, but I only want one of them to scroll vertically. So if I have a large panel on autoscroll, it works fine for that panel, but I have another smaller panel above that, could I make the smaller panel scroll horizontally with the larger panel's horizontal scrollbar?
I'm trying to make an autoscroll enabled panel that will scroll if the mouseposition.x > panel.location.y However, I cannot seem to find a panel.scroll() function. Is there a way to programable make the control scroll?
