Form 1 has a transparency key for custom title bar with a background image.
I set the child forms(Inside the MDIclient) back color the same with the transparency key I set for the parent. Now its like making a hole in that area.
Is it possible to set the child form back color to transparent? so that the parent form background image visible within that form... thanks for your answers...
[Solved] my own problem.
Just for sharing..
Put this in the constructor of the child form
Me.SetStyle(ControlStyles.SupportsTransparentBackColor, True)
Me.BackColor = Color.Transparent

I can't figure this out! I've researched docking, anchoring etc. but I'm yet to get it to correctly resize when the parent form resizes.
Edit:
Quick Overview:
I have a main form with a menustrip docked to the top and a panel set to fill. I have links within the menustrip which open forms within the panel. See code below. I am struggling to get the form within the panel to resize with the panel.
I've set the panel background to black and my form inside the panel to white. I can see the panel resizing with the form correctly. The form within the panel stays in its original position. If i start my app in maximized, then click on my menustrip sure enough the form within the panel resizes correctly. However, once it is maximized it doesn't shrink with the form like the panel container does.
I've deleted everything on my whole form, added 1 panel to it and set to fill then on form load do the following:
Dim f As New Contactdetails With {.TopLevel = False, .AutoSize = True}
f.Dock = DockStyle.Fill
Me.Panel2.Controls.Add(f)
f.Show()
This still doesn't work. When i maximize my main form, the form inside the panel does not resize but the panel does as i've changed it's background to monitor its change in size
Turn AutoSize off:
Dim f As New Contactdetails With {.TopLevel = False, .AutoSize = False}
f.Dock = DockStyle.Fill
Me.Panel2.Controls.Add(f)
f.Show()
If the previous form in the panel isn't being used anymore, then you should first dispose of it:
While Me.Panel2.Controls.Count > 0
Me.Panel2.Controls(0).Dispose()
End While
Set the WindowState to Normal in properties of the child form
and
Me.Dock = DockStyle.
Fill in the Load sub of the child form
I have created one button and applied image (.png with transparent background) on it.
My button background is set on transparent but as you can see the background color is still there.
How can I make this work as it should?
Give this a shot.
'Making Existing Button Transparent
btnKasa.FlatStyle = Windows.Forms.FlatStyle.Flat
btnKasa.FlatAppearance.BorderSize = 0
btnKasa.FlatAppearance.MouseDownBackColor = Color.Transparent
btnKasa.FlatAppearance.MouseOverBackColor = Color.Transparent
btnKasa.BackColor = Color.Transparent
Another option that I came up with is to call:
SetStyle(ControlStyles.SupportsTransparentBackColor, True)
when the form is created (e.g. in the constructor after InitializeComponent()). The button's BackColor is set to Transparent, as well (this can be done in code behind or in the properties).
I was trying to create a form in which some of the parts are transparent i.e I can click or use the form that is open behind the current form.
I have heard of transparency key as a way to do it but couldn't figure out a way to do it.
Me.TransparencyKey = Color.Transparent
When using TransparencyKey you have to state the part of the background color that you want to make transparent.
For example:-
Me.BackColor = Color.Green;
Me.TransparencyKey = Color.Green;
this will make all the visible portions of form that are green completely transparent
I've got a normal Winforms Panel, but under it, I've sent a (Awesomium) WebControl form to the back, and was wondering if it's possible to make the panel transparent to reveal the colors of the webpage basically, but simple solutions such as
Panel1.BackColor = FromARGB(0,0,0,0) (Or any other color)
make the backcolor the same as the Form's backcolor (Goes right through the WebControl). Is there any workaround? My original intent was to see if the panel could display the color under of the webpage, rather than the Form's backcolor.
Look, you have not explained your problem properly, so I can't tell exactly what problem you are getting.
Panel's color is by default transparent but for your convenience you can set the background as transparent.
Here is the code:
Panel1.BackColor = Color.Transparent
Or, if your form's backcolor is a plain color, you can try the following:
Panel1.BackColor = Form1.BackColor
Hope it works perfectly!
Using properties of "label" not able to set the backcolor as transparent ... when i select the color transparent from the option which is showing some color as backcolor, if transparent works properly must show background instead of some colors. please help
If you add a control at design time when setting the background to transparent it 'displays' the background of the form not the control on which it was placed unless that control is a container such as a panel.
2 options:
1 place the label on a panel and the label then displays the panel background (which can be a picture if that is what you are trying to do)
2 place the label programatically i.e.
dim Label1 As New Label
Control.Controls.Add(Label1)
Label1.BackColor = Color.Transparent
