Why does the WinForms SplitContainer hide all the Buttons in a Panel (in the left Splitter) when I resize on of its panels? Do I have to write specific code for invalidation of the Panel?
Yes, there's a solution. You can use Anchor property of SplitContainer in winforms. Using which you can set the value of the anchor as you required.
EDIT:
Anchor property will make your control fixed to the winforms design. Even if you resize the control, all the controls that the major control is holding will also resize according to it.

I just wondering about my windows Application. When i re-size windows form that time my Form controls should re-size. Can any body tell me how to do this I have Used Anchor property for that but no luck.
This is a win form.
there are two ways to make a control automatically resize based on size changes of the :
Set the Dock property of the control to DockStyle.Fill.
Set the Anchor property to "Top, Bottom, Left, Right"
But if you decide to use WPF GridLayout,it has a lot Capability for this target.
Edited
See this short tutorial Resizing controls with form: Anchor property Tutorial
You have to use the anchor property in properly.
For example, for DataGridview to resize in its all direction, you have to set its anchor property as Top, Bottom, Left, Right
You have to set the anchor property suitably for each controls in the form as per your requirement.
Hope this helps.
If you set the Dock property of your control to Fill. You could also take a look at the tableLayoutPanel if you have more controls which you want to keep aligned while resizing your form.
I want to auto resize my windows form controls on fullscreen. I use tableLayoutPanel and anchoring.
But it's not pleasing to the eyes. I used flowLayoutPanel, but it doesn't work. I have around 35 controlrs on one single form, including labels, textboxes, comboboxex, radiobuttons, datagridview and checkbox.
Is there any other method by which I can resize the controls? And if not, can anybody suggest me a way to use the tableLayoutPanel and anchoring more effectively?
It seems to me that what you want to use is the Dock property of all controls as well as using TableLayoutPanel. From the images you provided it looks like you want want the top half of the form to be a TableLayoutPanel, and to set the Dock Property to DockStyles.Fill. Then set the bottom ListView to DockStyles.Bottom.
You can either dock each control in a TableLayoutPanel cell or set the Anchor properties to AnchorStyles.None to make the controls automatically be centered in the cells.
I need to create a custom control that has an expandable part as a panel and a textbox part. The expandable part is a panel, that will either be visible or invisible. But when the panel is visible/expanded directly under the textbox, I do not want the adjacent controls to shift down below the panel, but the panel should just overlay the controls that are there just under the custom control. How would I implement this in Winforms C# project?
I am open to using user control for this scenario.
Thanks

I think your implementation of expanding and collapsing is not the best, because you are just overlaying the controls instead of hiding them.
One of the disadvantages is that the overlaid controls might by focussed by pressing tab and they might have a value which I think it is out of target.
I would suggest another implementation by creating two panels (one for the header and another one for the content) and when the collapse button is pressed then the content's panel will be hidden by sitting its Visible property to false and its Hight to 0.
I'm new to Windows Forms in Visual Studio, and I am wondering how to automaticly resize controls to the window size.
Say, I have 2 controls in a panel, a List Box and a Button. I want the button to dock to the bottom, and I want the List Box to fit the rest of the space. when the window resizes, the button should be at the bottom (as expected with docking), and the list box should stretch down to the button.
Is there a way to do this without any code?
Thanks.
Dock is pretty easy to use, but I recommend using the Anchor properties instead. Resize your form to a reasonable size in the Designer. Then, place your controls to look the way you want. Then, decide which controls should resize with the form and set the Anchor property as follows:
If you want the control to resize with the form in width, set the Right anchor.
If you want to resize height, set the Bottom anchor.
If you want the control to stay right when the form resizes, unset the Left anchor.
If you want the control to stay bottom when the form resizes, unset the Top anchor.
The problem I have with Docks is that they sometimes act funny when controls are not declared in a specific order, and to get the effect you want, sometimes you have to create extraneous panels just to hold controls.
It really gets messy when you want to maintain the aspect ratio of each control. One way, which is not really up to the mark if you want to get into fixing the details, is to use TableLayoutPanel and use Dock and Anchor wisely to achieve what you want.
Use the dock and fill options on the controls. Look under properties for each object, and containers if they are in any.
You can use SplitContainer
Google for examples. Here is one
Try setting your ListBox's Dock property to Fill.
You'll need to watch for one thing though: by default the ListBox will size itself to display whole list items. If you resize the control so that it displays a partial item it will adjust itself so it will display a complete item. This can make the control appear to lose its 'Dock'ing behavior. The solution for this is to set the ListBox's IntegralHeight property to false, which specifies that the control not resize itself to fit complete items.
typically in java if you have a layout manager of somesort, when you resize the page then the components in that panel will resize accordingly. I think my app is missing some sort of layout manager to control resizing as at the moment everything is just static
Is there a way to make it resize on the changing of the form size? say the user makes the page bigger, then the componenets adjust and so on.
Thanks
.NET has layout managers as well.
Personally, I prefer the TableLayoutPanel for my WinForms apps.
Once you layout the Table (using a combination of static/dynamic sized rows/columns) you add your child controls to the table cells. Once you add your controls, you can dock or anchor the controls to the cell so that they are automatically adjusted when the window is re-sized.
Two main options:
Anchoring. Set your control to "anchor" to the sides of your form. This means that if the form resizes, the control will stay a constant distance from that side. So, if you anchor Top, Left and Right, then your control will stay in the same position, but resize horizontally with the width of the form. Play with it. It'll be obvious.
Docking. Set your control to "dock" to a side of the form, or the center. This is usually done with containers, and it will make the widget take up that entire portion of the form no matter how large it gets.
In Windows Forms you make use of the Control.Anchor property, which will cause the control to adjust accordingly when the window resizes.
To do this with windows forms you use the Anchor and Dock properties of the control
