View 1 RepliesBasically I'm trying to make a layout change on a form if a link label is pressed. My main form I want this on has a "default" layout with a background image in place. What I want to do is, name the link label "Plain Layout". When the link label is clicked, remove or "hide" the background image and replace it with the background color of "control". After this action is performed, I need the text to change back to "Default Layout" and "show" the image.

View 7 RepliesI need to be able to change my form's opacity without changing the opacity of the components.
I really only need to do this on one form in my entire app, so this is getting a little frustrating
I've been researching for about half an hour now, trying to figure out if it's possible, but I'm coming up short.
I've seen some WPF examples and if it really comes to that, I'm more than willing to change the app from a WinForms app to a WPF app. I've made a WPF app before, so I'm familiar with it. But, I don't want to have to remake my entire project for this one form.
On that note, does anyone know if I can make a WPF form how I need it and just import it into a WinForm app? It doesn't seem possible, but it's better to ask than not. I'll look into this more.

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?
