For plugin activations, the ‘admin_notices’ hook cannot be used directly, because there is a redirect. A workaround is to store your notice in the options table and check for it next time. Also, if you also want to cover plugin upgrades as well as activations, you will need to use another hook, such as ‘admin_init’ … Read more
You are still not saying which control you want to remove, what type of controls you want to remove or how you want to identify them. You could just loop through the controls to remove specific Controls. If you have Linq, its easy: private void btn_Click(object sender, EventArgs e) { panel1.Controls.Clear(); //to remove all controls … Read more
Use a PictureBox if you don’t need scrolling support, it is double-buffered by default. Getting a double-buffered scrollable panel is easy enough: using System; using System.Windows.Forms; class MyPanel : Panel { public MyPanel() { this.DoubleBuffered = true; this.ResizeRedraw = true; } } The ResizeRedraw assignment suppresses a painting optimization for container controls. You’ll need this … Read more
Create a class that inherits from Panel. Set the ControlStyle.Opaque for control in constructor using SetStyle. If true, the control is drawn opaque and the background is not painted. Override CreateParams and set WS_EX_TRANSPARENT style for it. Specifies that a window created with this style is to be transparent. That is, any windows that are … Read more
I think it is more concise and understandable to describe the performance characteristics of each panel than it is to try to give an absolute relative performance comparison. WPF makes two passes when rendering content: Measure and Arrange. Each panel has different performance characteristics for each of these two passes. The performance of the measure … Read more

Looking at your code I’m afraid I have to say: This is all wrong. Sorry to be so blunt, but you must never use control.CreateGraphics!! The first thing to do is to throw away the Graphics objgraphics object. It is (almost) always wrong to store a Graphics object! Instead you have to use the one … Read more
Set the AutoScroll property to true and the AutoScrollMinSize property to the size of the image. The scrollbars will now automatically appear when the image is too large. You’ll want to inherit your own class from Panel so that you can set the DoubleBuffered property to true in the constructor. Flicker would be noticeable otherwise. … Read more
This can be done with CSS flexbox. Only minimal CSS is needed.. .equal { display: -webkit-flex; display: flex; } Just add .equal to your .row and flexbox does the rest. http://www.codeply.com/go/BZA25rTY45 UPDATE: Bootstrap 4 uses flexbox so there is no need for the additional CSS. http://www.codeply.com/go/0Aq0p6IcHs
