how to make viewback color of a propertygrid transparent
-
hello, the questions in the title. how would I do this. The reason is I am using a panel which has a gradient color scheme and I want to drop the property grid on the panel. But I dont want to ruin the gradient effect. Any Ideas?? thanks Martin

You can't do this without making your own PropertyGrid control and ownerdrawing the whole grid. The BackColor property of the PropertyGrid doesn't support Transparent.

2006, 2007thanks for that dave, speaking as a person who has never ever used VB's drawing commands and as someone who had a play at the weekend and got nowhere - how would I do that? any tips, ideas, code??? thanks Martin

You start with creating your own PropertyGrid class, inheriting from the existing class.
Public Class MyPropertyGrid
Inherits PropertyGrid
.
.
.Then you override the OnPaint and/or OnPaintBackground methods and supply your own drawing code to draw everything you need. If you haven't used the drawing methods, or even have a basic understanding of how painting works, you're going to find this a frustrating process. Google for "vb.net drawing" for lots of examples and articles.

2006, 2007hi, I have tried Public Class myProp Inherits PropertyGrid Protected Overrides Sub OnPaintBackground(ByVal pevent As PaintEventArgs) MyBase.OnPaintBackground(pevent) Dim g As Graphics = pevent.Graphics Dim gradBrush As System.Drawing.Drawing2D.LinearGradientBrush gradBrush = New System.Drawing.Drawing2D.LinearGradientBrush(New Point(0, 0), New Point(Me.Width, Me.Height), Color.Green, Color.Blue) ' g.FillRectangle(gradBrush, 0, 0, Me.Width, Me.Height) g.FillRectangle(gradBrush, pevent.ClipRectangle) End Sub Protected Overrides Sub OnPaint(ByVal pevent As PaintEventArgs) MyBase.OnPaint(pevent) Dim g As Graphics = pevent.Graphics Dim gradBrush As System.Drawing.Drawing2D.LinearGradientBrush gradBrush = New System.Drawing.Drawing2D.LinearGradientBrush(New Point(0, 0), New Point(Me.Width, Me.Height), Color.Green, Color.Blue) ' g.FillRectangle(gradBrush, 0, 0, Me.Width, Me.Height) g.FillRectangle(gradBrush, pevent.ClipRectangle) End Sub but these dont seem to cover the area where the "view back color" paints. In actual fact they seem to paint on only one or two lines between the text time and the outer rim of the cocontroller area. thanks Martin

First, you don't create your own Graphics object. You'll find it in the PaintEventArgs that you're getting when your code is called.
Dim g As Graphics = pevent.GraphicsYour next mistake is that if you want to REPLACE the background functionality, you don't call the base classes OnPaintBackground method. That will paint the background of the control just like you didn't even attempt to make your own version of it. Third, the Graphics objects to DID create, you didn't Dispose of. This will, most assuredly, run your machine out of resources and your app will eventully crash with an OutOfMemoryException. On top of that, if you didn't create the object, like Graphics, you do NOT Dispose of it.

2006, 2007hey, this was just sample code and not clean in any way.

er if you look at the snippet - thats exactly what I do MyBase.OnPaintBackground(pevent) Dim g As Graphics = pevent.Graphics

dont really want to replace them as overwrite on top of them thats why I ran this first. Interestingly enough if I dont run the base classes then I get the same result.

absolutely - this is a proof of concept , rather that a clean solution. Of course I will dispose of them properly when the solution happens. My problem is that my color gradient only appears behind the propertygrid ( its its view back color area).Effectively this means a couple of lines at the top of the pG and a couple between the description block and the rest of the PG. Try it and see what I mean. I need to change the color of the view back color area to a gradient which is the bit where there is no properties left to display on the PG. Pick a class then use the category view and minimise ecah category - the coloured background at the bottom is what I am after. thanks Martin

My bad! I misread your code! :->

In order to get a transparent background, you have to replace the background drawing code. That's what your original post said you wanted.

This would mean that the background of each "cell" in the PG is painted by the foreground OnPaint method. You would have to replace the standard OnPaint drawing code with your own. This means that you have to paint the entire control yourself! Is it worth it?

hi, I have added this to the properties grid onpaint event
Protected Overrides Sub OnPaint(ByVal pevent As PaintEventArgs) ' MyBase.OnPaint(pevent) Dim g As Graphics = pevent.Graphics Dim gradBrush As System.Drawing.Drawing2D.LinearGradientBrush gradBrush = New System.Drawing.Drawing2D.LinearGradientBrush(New Point(0, 0), New Point(Me.Width, Me.Height), Color.Green, Color.Blue) ' g.FillRectangle(gradBrush, 0, 0, Me.Width, Me.Height) g.FillRectangle(gradBrush, pevent.ClipRectangle) End Suband I expected the control contents to vanish and be replaced with a gradient colour but nothing happened. does this mean each cell has its own onpaint function?? if so how do I find them ???Dave Kreskowiak wrote:

yes if I can - I am trying to have a consistant look n feel in my gui app. of course scroll bars seem to be a problem because I cant find where to cheange them either. so yes any help would be appreciated Martin thanks Martin
