Panel + Groupbox
-
Having become lazy, I've done so much as to check MSDN. Basically I have a panel, and a bunch of groupboxes which I would like on that panel. The groupboxes are hidden/displayed and moved depending on the user instructions at runtime. It all worked great without the panel (simply on the form), but with it, it doesn't. The panel contains a button to hide it, which no longer works, and the groupboxes don't appear in the panel, regardless of whether or not I have them in the panel within the designer. My question isn't fix it but, is there some trick I've missed with panels, to make their contents display? It works, in that it displays the button and the button changes on mouseovers, but it doesn't work. It seems that the panel doesn't redraw itself entirely, but I added some calls to refresh it after moving the panels which has no effect.

Without some brief, relevant snippits of your code it would be hard to help you. Also, don't call yourself lazy, even if you are; admitting to being lazy, and yet expect that I, or anyone else here help you, seems insulting and as a general rule I tend not to help people who insult me.

The laziness was about me...because for the last 4 years (before I became more reliant on the internet) I could sit for hours testing and testing until it worked, or I came up with something better. This time I've given in because I know there are plenty of people out there who do nothing but use panels for their interface (and they work). There's no code needed, I would expect. All of the following was/is done at design-time. There's a form. Upon that, are groupboxes. Without any panels, the groupboxes display and the buttons work fine (they execute their click events). Then I added the panel, moved the groupboxes so that they were [definitely] in the panel, and the relevant buttons too. Now, the buttons appear but do nothing when clicking on them, and the groupboxes don't appear. All of the groupboxes initially have their Visible property set to false. The buttons are visible. Hopefully that's clear enough.

I tried to duplicate your problem doing the following: added a panel to a form put a groupbox on the panel put a button on the groupbox set the visible property on all three to false. set the visible property of all three to true on the for double click event of the form. put messagebox.show("Test") in the click event of the button. ran the app. double clicked the form; The panel, groupbox, and button showed. clicked the button and it worked. The windows forms designed code for what I did is: this.panel1 = new System.Windows.Forms.Panel(); this.groupBox1 = new System.Windows.Forms.GroupBox(); this.button1 = new System.Windows.Forms.Button(); this.panel1.SuspendLayout(); this.groupBox1.SuspendLayout(); this.SuspendLayout(); // // panel1 // this.panel1.Controls.Add(this.groupBox1); this.panel1.Location = new System.Drawing.Point(72, 56); this.panel1.Name = "panel1"; this.panel1.Size = new System.Drawing.Size(400, 320); this.panel1.TabIndex = 0; this.panel1.Visible = false; // // groupBox1 // this.groupBox1.Controls.Add(this.button1); this.groupBox1.Location = new System.Drawing.Point(32, 32); this.groupBox1.Name = "groupBox1"; this.groupBox1.Size = new System.Drawing.Size(336, 264); this.groupBox1.TabIndex = 0; this.groupBox1.TabStop = false; this.groupBox1.Text = "groupBox1"; this.groupBox1.Visible = false; // // button1 // this.button1.Location = new System.Drawing.Point(40, 48); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(88, 24); this.button1.TabIndex = 0; this.button1.Text = "button1"; this.button1.Visible = false; this.button1.Click += new System.EventHandler(this.button1_Click); // // Form2 // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(576, 469); this.Controls.Add(this.panel1); this.Name = "Form2"; this.Text = "Form2"; this.Load += new System.EventHandler(this.Form2_Load); this.DoubleClick += new System.EventHandler(this.Form2_DoubleClick); this.panel1.ResumeLayout(false); this.groupBox1.ResumeLayout(false); this.ResumeLayout(false); Review your forms designer code and see if you see anything weird. If not, try and duplicate your problem in the simplest possible way and outline it as I did above.

Having followed your guide (except, in VB this time :-D) I get the same results as you and I and any sane person would expect. I had a panel, a visible button which made an invisible groupbox, visible. The original project still ain't working. The data's working, it seems that the panel can't handle things moving around inside of it. Thanks for your time, but I'll go bury my head in some strange code for now. There's only so many psychologists willing to help frustrated programmers left.

Something keeps tickling the tip of my brain. An odd problem I once had when dragging exising controls into a panel. Can't remember the details, but seem to remember (and it will be a huge pain to do this) that I ended up starting over and creating a new form and adding a panel and new controls in the panel and the problem cleared up. Meant I had to copy over all of the other code from the existing form and of course recreating the whole ui itself is a pain, but when you truely have given up it might be worth a try.

Your groupbox's (if I followed this thread correctly) are not in your panel controls. It can appear on top of or under the panel, but you didn't drop the groupbox from the Toolbox ON the panel. You dropped it on the form, then tried to move it into the panel. This just moves the groupbox over the top of the panel. All you have to do is add the groupbox control(s) to the Panel's Controls collection:

Funnily enough, I did just that last night. Had a second project, copied the form and relevant code over. It's the bare minimum to have it working as it was - still doesn't work though. I daresay I could do it the long way around. There's 4 groupboxes causing problems and each has less than 10 controls on it. Nothing really complex, and there's not exactly a deadline.

2006, 2007Unfortunately, I made sure of it. Dragging them over, and then within the panel to the edge of it, it stops drawing outside of the panel. I also checked and the pnlPanels.Controls.Add() lines were all in the designer code, and that was what I got from MSDN - adding those lines to my Form_Load code. Plus, sometimes (not always) when you drag a control within a panel or a groupbox, the cursor changes and a dotted box appears next to it. Not very obvious if you're working at speed though.

I've given up. The reason I needed the panel was because I wanted to use GDI to draw on the rest of the window and the panel seemed the easiest way of me not having to draw under the groupboxes. So I figured, dispose of the panel (well, delete it - it's not being created to be disposed :-P) and just add another (complex) rectangle to the GDI code. Thanks anyway folks, but it seems like one of those bugs that just happens.
