I set the borderstyle of my form to none but this title bar still appears and i have no idea what this belongs to
This is when i set my border style so that it is visible
Try setting the ControlBox of the form to false, like this:
Me.ControlBox = False

I have set a Panel to AutoScroll = True.
I host a button in this panel.
When I set the button to a new location outside the panel's visible area...
.Location = New Point(2000, 0)
... this doesn't make the scrollbars appear.
How could I force the panel to invalidate / check again if the scrollbars should be shown?
I got it:
I need to set the button's parent to something else, then add it to the panel again which raises the ControlAdded event.
On my form, I have 4 RadioButtons, each with its appearance set to Button. In my program, I change each of these RadioButton's ForeColour, BackColour and AutoCheck status, as below:
ARadioButton.AutoCheck = False
ARadioButton.BackColor = Color.FromKnownColor(KnownColor.ControlLightLight)
ARadioButton.ForeColor = Color.FromKnownColor(KnownColor.ControlDark)
However, later on, I reset these properties back to default:
ARadioButton.AutoCheck = True
ARadioButton.BackColor = DefaultBackColor
ARadioButton.ForeColor = DefaultForeColor
My issue is that instead of the entire button being highlighted, only the outside is, as shown in the images below.
Originally:
After changes are made and RadioButtons reset to default using code above:
I know this may seem trivial, but I would like the entire RadioButton to be highlighted when the user clicks on the RadioButton, not just the outside.
Is there a way I could somehow reset this?
Try setting the BackColor property to Color.Transparent
I have a Form with a Panel. In this Panel, I want to use the vertical scrollbar when I needed.
How do I do this? I've tried setting autoscroll true and set a min scroll height, but the scrollbar never appears.
I've also tried this:
my_panel.ScrollBars = ScrollBars.Vertical
but then I get the error that scrollbar is not a member of my_panel?
Thanks.
Autoscroll property is actually enough to achieve your need. Basically a panel with autoscroll property true will display the scroll bar only when the contents/components inside that panel exceeds over its bound. In other words, Scroll bar appears with controls which have autoscroll property set to true when the particular control's contents are larger than its visible area. I think your panel is having some minimum amount of contents/controls which fits inside that panel's bound.
I know You asked this question more then year ago, but... ;)
Recently, I had same problem (label inside panel, and I need only vertical scrollbar).
If You want only vertical scrollbar of panel with label inside, use code bellow :
Dim pnl As New Panel
pnl.Size = New Size(300, 200)
pnl.AutoSize = True
Dim lbl As New Label
lbl.Location = New Point(0, 0)
lbl.AutoSize = True
lbl.MaximumSize = New Size(pnl.Width - 18, 0)
'18 is approx. width of scroller, and height must be zero.
'even if Label is set to AutoSize, MaximumSize will not allow him to
'expand more then set width.
'Height of zero px will allow Label to expand as much as he need
pnl.Controls.Add(lbl)
Me.Controls.Add(pnl)
I hope this code help You.
btw. sorry for my weak English, I hope You will understand ;) :)
I am developing a Windows Application in VB.Net. In that, there is one case where there is one form, and in that form there is a Panel, and within the Panel there is a rich text box.
So my requirement is to get a scrollbar in the Panel. So when the user does scroll on the panel, the rich text box can scroll accordingly like MS Office functionality..
Can any one give me an idea how to do it?
Set Panel.AutoScroll = True and scrollbars will automatically appear whenever any controls in the panel fall outside its boundaries.
Set the .Dock property to FILL and the .WordWrap property to FALSE for the richtextbox.
Also set the Panel's .Dock property to FILL.
In order to use panel autoscroll property I do that:
panel.AutoScroll = true
panel.VerticalScroll.Visible = False or panel.HorizontalScroll.Visible = False
In order to know the dimensions of the scroolbars use
SystemInformation.HorizontalScrollBarHeight
SystemInformation.VerticalScrollBarWidth
So you can change the dimension of the panel when the scroolbar is shown.
I need to change the contextmenustrip width dynamically, by default the contextmenustrip width depends on the text length of the ToolstripmenuItems.
And BTW I really don't wanna redraw the control again!!!
Thanks in advance.
You need to set the ContextMenuStrip AutoSize property to false. Then you can set the Width property to whatever you want. When AutoSize is set to true, the Width property is ignored and is calculated dynamically.
Example:
Dim menu As New ContextMenuStrip()
menu.AutoSize = False
menu.Width = 100
AutoSize does a VERY poor job of guessing at the "correct" size anyway.
When TRUE, the menu is far wider than any of the text would need it to be.
When you set it manually... you also have to set the HEIGHT to be far less than you would expect... if you want it to display in the correct size menu.
