How to make a FlowLayoutPanel Resizable at runtime? - c#

I have this GUI for my Winform application with 2 FlowLayoutPanels Docked top and right respectively.
Right now I can only give them a fixed size which cannot be changed by user at run time but I want to make these panel Resizable while the application is running.
I've tried BorderStyle Property but only available options are Fixed3D and FixedSingle which are obviously cannot be resized due to their Fixed! behaviour.
I've already gone through the documentation at MSDN but couldn't find anything.
I want to know if I can make them resizable programmatically?

Maximize Entire Window Visual C#

I have an application designed in visual C# that is about a quarter of a normal computer screen. The reason its that small is because its easier to work with in Visual Studio. However, I would prefer if when I run it, it maximizes to the full screen. I tried this in my Main_Load:
this.WindowState = FormWindowState.Maximized;
This causes the window itself to maximize, but the application itself is still quarter of the screen. Is there a way to maximize the application itself, and not just the window?
I am guessing you have not docked or anchored any of the controls, meaning they will not move when the window is resized.
Have a look at docking here: https://msdn.microsoft.com/en-us/library/system.windows.forms.control.dock(v=vs.110).aspx
And have a look at anchoring controls here: https://msdn.microsoft.com/en-us/library/system.windows.forms.control.anchor(v=vs.110).aspx
Both pages should help you understand how to make controls resize with the window.
Either you change the size of your application window in the visual studio designer so it fits your personal screen (bad idea), or you make your application aware of window size and window size changes and actively scale parts of the GUI programmatically (better).
If WinForms, as others have stated, you need to Anchor and/or Dock your controls so they know how to resize in relation to the Form when the Form size changes. These will work for simple layouts.
For more complicated needs, however, check out the TableLayoutPanel and/or the FlowLayoutPanel.
A robust User Interface is probably going to be using all of these elements in one way or another...

Winform: SplitterContainer inside a SplitterContainer misbehaves

I have a splittercontainer (vertical) placed on form. In the right panel, I placed another splittercontainer (horizontal).
When I run the application, the topmost splittercontainer works fine, no issues. The problem is with the embedded splittercontainer.
The size of the embedded splittercontainer when resized is fine, however the panels show up as a smaller size. I did not even thing that was possible. I cannot seem to get the embedded panel to consistently show the proper dimensions.
I did a search, and turned up this article.
http://support.microsoft.com/kb/953934
I tried out the recommended solution, and quite usual for any Microsoft post, it does not work.
In fact, things worked better without the suggested solution. At least after the application showed, I was able to get the panels to size properly, just by adjusting the splitter container of either control.
Thoughts?
Thanks in advance,
Sarah
After suffering for quite some time, it seems that posting my question got my head to think of a solution.
The outer splittercontainer must be set for docking type fill. Embed the second splitter container directly inside Panel 2 and have that set to docking type fill.
In the resize event, do not add any Controls.Add() for the splitter container, as that is done in the designer. You should add a Controls.Add() for any forms that you want to show.
Do not size the splittercontainers. Allow Windows to do that. Do resize the forms. Make sure to set the TopLevel to false first and show the form after adding to the control of the panel.
I tried the docking type none and several other things. It was either setting to none or setting the manually setting the sizing or whatever that caused the problem.
I hope this post helps someone.

C# Toolstrip Causes Supporting Form to Grow

I've rewritten a toolbar that sits at the top of the user's screen. It works, but for some reason, though the app consists of just a form with a Fill-Docked ToolStrip, I cannot get it to stay at the size I specify. It's supposed to be the size of the Windows titlebar, as designed in Visual Studio, but as soon as I run it, it's grown in height by five or six pixels. Everything is set rigidly, the Form and ToolStrip are set to AutoSize=FALSE and I've specified the size in pixels the form should be. I cannot work out what is resizing the form at runtime; the ToolStrip is Docked on Fill mode so it should not cause the form to grow. It all looks perfect in the GUI builder, and I copied most of the configuration from the old VB.Net toolbar it will replace. Can anyone help?
Just a wild guess, but have you tried changing the AutoScaleMode property of the Form to something other than Font?
Haven't found an answer but I'll make sure this is closed. I turned the form transparent and it accomplished what I needed. Still unsure why the form expanded when run.

c# panel layout problem

I have created a panel in c# application that holds rows of 5 textboxes.
Textboxes are added to panel dynamically. It is 500 pixels in width and each textbox is 100 pixels wide.
First textbox is at x-position 0, second at 100, third at 200 and so on.
So the 5 textboxes should fill the panel horizontally. These are shown correctly at my computer but at another computer these textboxes appear as if their width is reduced and they do not extend to end of the panel. They leave blank space at the end of panel.
Can anyone tell me why is this difference in display of textboxes?
There could be a few different reasons for this. Depending on if you are using WinForms (which I am assuming) or WPF. There is a system DPI that can be changed in windows. Windows Vista and 7 take advantage of this more. The other issue could be with the windows themes (play with the handicap themes). How to check your system DPI
I think that the problem is in displaying textboxes in computers with diferent Windows themes.
With Classic windows controls it compute space in different way than when themes are turned on on computer.
Couple things to try, make sure the AutoSize property is set to false on the Panel and the Textboxes. Also, make sure the PreferredSize is also set.
I was having a similar problem, and found this link:
C# WinForms messed up control positions?
where changing my main form's AutoScaleMode attribute from Font to None or Inherit solved the problem (NB: changing to Dpi did not solve it).

c# Program in Windows 7 moves Panels around

I have an application I have been working on for a while in VS2008 developing in Windows XP and it has some panels placed in specific spots so the borders line up and look nice and pretty. Now that I have switched to developing in 7, as far as I can tell everything else is in the same place but it moves both panels over a little bit and one up and one down and messes up my nice borders. Since it still works correctly in XP I'm assuming this is a 7 problem or a VS problem with 7. Anyone have an idea whats going on or if its fixable?
So I figured it out. Turns out the client area wasn't narrower, however the titlebar which is part of the dialog box border was two different sizes in XP and 7. Since the panels were in an mdi child, where the border was not shown because it was underneath the parent, the size of the titlebar part of the border was making a difference in the location my panels were shown relative to the parent. To solve this I set FormBorderStyle to none on the child and re-positioned the panels to be in the correct spot without that titlebar. It now looks the same in XP and 7 since that variable bar size is gone.
Windows in Windows 7 have wider borders.
Your form probably has a fixed size that is based on a Windows XP border width.
Therefore, in Windows 7, the form's client area will be narrower.
If this is in fact the problem, you can solve it by setting the form's ClientSize property in the constructor the the value it currently has in XP.
If this is not the problem, please post more details.
Do you need to have your panels pixel-positioned? .NET 2.0 introduced the FlowLayoutPanel and TableLayoutPanel for resizeable positioning of elements.
The TableLayoutPanel is the more useful of the two. You create rows and columns, which can autosize or size proportionally to each other. You dock the TableLayoutPanel in your form or anchor it to all four sides. Then the user can resize your form and everything resizes with it.
Even if your panels are of a specific size, you can anchor them to a side or a corner so that they stick to the side even if the user resizes the form.
