C# Windows Form - Anchor - c#

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

Visual studio, fill space

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

How do I set dock property of a datagridview properly?

In a datagridview when I set:
Anchor: Top,Left
AutoSizeColumn: Fill
Dock: Fill
Which will expand or shrink the datagridview based on size of the form, and covers the whole form. But what of I have controls on the right side on the form? I don't want to overlap my linkbuttons with my gridview. I know there's a "Margin" and "Default Cell Style" property with padding values (specifically using "right padding" to try and reduce width from the right of the right edge of the form). So I tried messing with that, didn't do anything I want. Or was I working with the right properties, just not setting them right?
Put those controls you want on the right in a Panel.
Set the DockStyle of that panel as DockStyle.Right.
If you can't see the right edge of the Datagrid means, you have to bring the Datagrid to front by selecting it, right click and choose bringToFront.
Or Send the Panel to back.
1.Use a panel to split the form into two sections.
The right section is placed with DataGridView, and the left section is placed with a panel which is used to contain your other controls, like linkbuttons.
2.Set the Dock property of this panel to Right.
3.Set the Dock property of this DataGridView to Fill.

Resize components inside user control while maximiziing

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.

How do I make multiple controls in a Windows Form automatically resize with the window?

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.

How to get the Width/Height of a collapsed control in WPF?

im wondering if theres an easy way to get the width of a control in WPF at runtime while the control is collapsed.
when i use control.Width ill get the following result: -1.#IND
and control.actualWidth will return 0.0 because its collapsed.
i want to resize my window and then display the collapsed control.
thanks
Edit:
Some details
i have a grid with 2 columns in my window, the 1st column holds a tab control, the 2nd column holds an expander control. i want to extend the width of my window when expanding the expander control, so the content in the 1st column will remain its size.
Put the control in question inside a container (like a ContentControl) and collapse the container rather than the control itself. Then you should be able to simply call Measure (or use the DesiredSize property) on the control to determine how much room it wants.
What size do you expect to get?
The size is not just dependent on the control but also on its container. So the actual size can not be determined unless the control is actually rendered.
Instead of using Collapsed you could make it Invisible that way it will be sized by its own logic and the logic of the container.
EDIT
In the comments it became clear that what the reason was for needing the size of the control:
I have a grid with 2 columns in my
window, the 1st column holds a tab
control, the 2nd column a holds an
expander control. i want to extend the
width of my window when expanding the
expander control, so the content in
the 1st column will remain its size.
My answer:
Set the SizeToContent of the window to WidthAndHeight and set the width of both grid columns to auto. That should take care of it.
I believe you're going about this the wrong way. You can set the Window Width and height to "Auto" and then it will take care of all the resizing stuff.
The problem arises whenever you directly set the Width property of any control(trust me I've done it). Once you do that, you've told WPF hands off of resizing logic, I know what I'm doing.
If you think something isn't resizing at the right time you can add a handler to some event and then call control.InvalidateVisual() or control.InvalidateMeasurement() which will make it go through a whole new layout pass.
You have to call the UpdateLayout method on the control or conainer of control. After that the things may work properly.
In UWP you can determine size of collapsed control by making it visible for a sec and then hiding it again, change is not noticeable:
var oldVisibility = myBorder.Visibility;
myBorder.Visibility = Visibility.Visible;
myBorder.UpdateLayout();
var height = myBorder.RenderSize.Height;
myBorder.Visibility = oldVisibility;
Post which is marked as an answer actually does not answer the question, it just gives a workaround.
To get the size of the collapsed control you need:
Set control's visibility as Hidden (Collapsed won't evaluate).
Call Measure(new Size(Double.PositiveInfinity, Double.PositiveInfinity)) method of the control.
Get the size from DesiredSize property of the control.
Then you can Collapse your control back.
