I am using c# and i am creating a simple design where i have a user control and some components inside it like treeviews and buttons. I am trying to fill a treeview with some nodes and drag-drop these nodes to other treeview and use the buttons to also copy nodes from side to another.
The problem i am having is that when i maximize the window containing this user control there is no effect on the inside components.
I have set the Dock property of the user control to Fill.
I have changed the anchor properties of the buttons and treeview inside the user control but the behavior wasn't as expected. For example i have tried to set the anchor property for the right treeview to be Top,Bottom,Left => and the result was a disaster
I have also done a lot of combinations for the anchor property of all the buttons but nothing gave me the right behavior. I just only need to maximize the window form and the controls will be maximized with the same proportion.
It sounds like you want a "3 column" interface where you have a TreeView on either side and Buttons in the middle to allow movement between the two. Assuming this is correct, you can accomplish your automatic resizing by using a TableLayout.
Essentially, it would be like this:
Add a TableLayout and edit the rows/columns such that there is a single row with 3 columns:
The first and last column would be sized at 50% (and would hold your TreeViews).
The middle would be an absolute size of (for example) 120. This would hold your Buttons.
Set the properties of this new TableLayout to Dock -> Fill the form. This will size the entire table to grow with your form.
Add your TreeView controls to the left/right columns and set them to Dock -> Fill the respective columns. Since these columns are dynamically sized, they will grow with the form.
In your middle column, add a Panel and set it to Dock -> Fill. We add a Panel here to hold the multiple Buttons you use for movement. This Panel will not grow in size because the middle column is sized absolutely.
Add your Buttons to the middle Panel.
Without a screenshot, I'm not completely sure what you are trying to achieve but I believe this is along the lines of it. The nice thing about this setup is there is zero code involved.

I have two elements in the form, two GridViews.
Both of them are aligned horizontally at the same level.
When my form is resizing, I want both of them to change their width/ height according to the form size.
The problem is, if I try to anchor them, they kinda overlap at some point and I want to avoid that.
My question is, can I anchor one Grid View to the other Grid View and not to the form?
A solution can be a TabelLayoutLabel, but i don't really want to use this.
My question is, can I anchor one Grid View to the other Grid View and not to the form?
no you cannot, and if you could that would be bad practice.
the anchor property description by microsoft:
Gets or sets the edges of the container to which a control is bound
and determines how a control is resized with its parent.
a dataGridView is not a container it's a control.
it sounds like you should use a table layout panel, that would give you the best results.
search for it in the Toolbox:
make sure you set its property to Dock = fill, where ever you want, and
,
next. in the property of the table view, you enter Edit Rows And Columns
and set each column to the percentage that you desire
add your grids to each column,
and set each one's 'Dock' property to Fill, and there you go
you can undock the tableLayoutPanel and change its size,
Hope that was helpful
In my form I put three charts. I want to fill all available space, and tried to set dock fill, but in this case the charts overlaps each other. I want, instead, to have every chart next to others.
How can I fill all the space, without overlaps?
As mentioned in the comments you want to use a FlowLayoutPanel or TableLayoutPanel. Below are two examples of TableLayoutPanel which may be better because you can more easily control the desired layout.
The examples below use panels instead of grids but the idea is the same for whatever control you want to put inside the TableLayoutPanel.
In both examples, the Dock property of the TableLayoutPanel and all 3 components is set to Fill. This will cause everything to resize automatically as the form resized. Additionally, there is a Rows property and Columns property on the TableLayoutPanel which will allow you to set either pixels are percentages of the table a cell should consume.
Example 1: 3 panels side by side
Example 2: 2 panels above a third panel. In this case you set the ColumnSpan property to 2 on Panel 3
I have created a user control in which I have a datagrid along with other items.
One of the functionalities of these control is that through two buttons I can add or remove columns from the DataGrid.
Multiple of these controls are placed inside a WrapPanel, to display in my main application.
Now while running my application and I press the button to add a new column to the datagrid, the datagrid changes size and as result the initial user control becomes wider, which means that one of the childs of the wrappanel is wider than the other ones.
If I add multiple new lines and the user control reach the width of the application window then a scrollbar apprears below the datagrid so I can scroll and see all the contents in the datagrid.
Is there any way to prevent this behaviour?
Ideally I am looking for my wrappanel child to have a constant size, and my datagrid directly to present the scrollbar upon addition of a new column in it. Thus all the wrappanel childs have the same width.
I dont want to place a specific constant size to my user control if that is possible.
It is possible to achieve the same result with a Grid than with a WrapPanel, just a little bit less handy.
Starting from a grid you can set Width/MinWidth/MaxWidth (with star notation) and Height/.../... to get the behaviour you want.
I have a WinForms application which has two panels which individually contain a usercontrol component (one in each panel). How ever, because both panels are the same size and in the same location, the top most panel becomes a child of the other panel. I want to be able to hide one panel and then show the other panel:
this.panel1.visibile = false;
this.panel2.visibile = true;
But when I hide panel1, the second panel is hidden as well.
How can I make panel2 a non-child of panel1?
I like to keep things simple because I'm new to C# Programming.
This is a common accident in the designer. Dropping the second panel on top of the first one will make it a child of the first panel. Two basic strategies to fix this:
View + Other Windows + Document Outline. Click the second panel in the list and drag it to the form. You'll need to fix up the Location property by hand by typing its value in the Property window.
Keep the upper left corner of the second panel just a bit to the left or top of the first panel. Put it in the right place in the form's constructor by assigning its Location property after the InitializeComponent() call.
Check this answer for a control that works well at design time and lets you easily flip panels at runtime.
The designer will do this automatically because it assumes that when you drag one control over another, you want to make it a child of that control.
What I usually do to get around this is to create the control in a different place on the form, and then use the properties to manually match the positions of sizes of the two controls.
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.
