I have 2 items FlowLayoutPanel each includes some buttons and has autosize property. Then I have a simple Panel docked to left. My FlowLayotPanels docked inside that panel one to top, second to bottom. I dont want to set static width to docked to left panel, but if I set autosize to that panel, it shrinks to zero. Somehow it doesnt "see" sizes of autosized FlowLayoutPanenls inside of it.
How to force Panel to see size of FlowLayoutPanel inside?
Assuming that your inner panels do have content, or at least a fixed minimal size, the only thing i can imagine without some code is that you did not set the hierarch properly... You can do that by MyParentPanel.Controls.Add(MyChildPanel1);

I am making a simple WinForms program.
I would like to link a component's size to the size of the Window.
Let's say the user enlarges or shrinks the Window by dragging it's borders: I would like that a component gets bigger when the Window does and vice versa.
Let's pretend that we have two Buttons, in the center of the Window, side by side: I want to make them the same size filling the entire width of the Window.
How can I do that?
Sample procedure, using a TableLayoutPanel and 2 Buttons:
Add a TableLayoutPanel to the Form
Edit the Columns and Rows collections so that you have 2 Columns, both sized at 50% and one Row, set to Autosize.
Set the Location.X of the TableLayoutPanel to 0 and adjust its width to the width of the Form.
Set the TLP Anchor property to Left and Right
Adjust-drag the Row height to be ~twice the size of the Button it will host
Add one Button to the Form
Adjust the appearance of the Button as required.
CTRL-Drag the Button to create an exact duplicate
Add the two Buttons to the two cells of the TableLayoutPanel
SHIFT-Select both Buttons and set the Dock property to DockStyle.Fill
You can now adjust the Margin property of the Buttons (still both selected, so the same settings will apply to both) to modify the space between the controls
Re-adjust the TableLayoutPanel's only Row height as needed.
Extra: if you have only these controls on the Form, you may want to fix the MinimumSize of the Form, to avoid that, when the Form is resized, your controls are shrinked beyond recognition, ruining the overall layout: resize the Form in the Designer to a point where the hosted controls layout is compromised, find a suitable minimum size and use this measure as the Form's MinimumSize property. The MinimumSize can be set using only the Width or the Height measure (e.g., (100, 0)). This limits the Form's Width but not the Height. Or the opposite, of course.
If, when dragging the Buttons inside the TableLayoutPanel, the Buttons
are not automatically inserted at the Top-Left position of the cell
and instead they appear positioned in a random place, then the
TableLayoutPanel has gone rogue and needs to be put down. Delete it
and drop another on the Form. Rinse and repeat.
This may happen if you tamper with the layout a bit. Better start over than trying to correct the problem.
TableLayoutPanel Control Overview
I have a navigation panel on the left hand side of my program and I'd like it to always stay where it is when scrolling the window content. Is there a way to do that?
I've thought about trying to do a get/set for its position but there's only a size property.
In the example above, the information in the top left is in a panel. Is there a way to keep it anchored there as the user scrolls down?
You currently appear to have the Autoscroll option enabled on the Form. Set that to false, then set up two panels, one for the toolbar/navigation and the other for the scrollable content.
Set the toolbar panel to be anchored to Top, Bottom, Left. Set the content panel to be anchored to all four sides. Set both panels to Autoscroll=True, then put the content in each panel. When each panel gets too small to contain their contents they will scroll - independently - which will in most cases mean that the toolbar/navigation will stay put while the content will be scrollable. If the toolbar panel also gets too small then it will be scrollable too:
I have a form set up as shown in the picture below. The form simply contains a SplitContainer with two TreeViews in each of the panels, plus the label above the TreeView.
Here's a picture of the form that has not yet been resized:
Each TreeView is anchored to the Top and Left, and docked to the Bottom.
Each label is anchored to the Top and Left.
The SplitContainer is anchored to the Bottom, Left, and Right.
The above settings allow me to resize the TreeViews equally when the form is resized. However, when I resize the form's height, the labels (and of course the TreeViews as well) are pushed out of the form view, as shown in this picture:
How can I prevent the elements from being pushed past the title bar? Preferrably without the use of a SizeChanged event. I have tried adding padding to the form, as well as trying different docking/anchor modes, but I have been unable to restrict this.
Perform the following steps in order:
Either anchor the SplitContainer to all 4 sides or dock-fill it.
Place the labels on the panels. Make them smaller than the panels, in order to be sure that they really become child controls of the panels (and not of the form). Set their Dock property to Top.
Place the TreeViews on the panel. It is important that this is done after you placed and docked the labels! Same thing here: make them smaller than the panels. Then set their Dock property to Fill.
Note: you can either dock or anchor a control, but not both! The Anchor property is ignored if Dock is something else than None. An anchored edge keeps a constant distance to the side it is anchored to. If an edge is not anchored, the size of the control in this direction will remain unchanged. If two corresponding edges (e.g. left and right) are not anchored, then the control will be centered in this direction.
See: Manage WinForm controls using the Anchor and Dock properties
Set SplitContainer.Dock = DockStyle.Fill; if thats the only thing appearing on the form.
I have a UserControl which I'm going to place into a DevExpress PopupControlContainer.
I want the UserControl to auto-size to fit at least its content, which is a PanelControl containing two buttons, docked to the bottom, and a ListBoxControl docked to fill the rest.
The UserControl's and panel's AutoSize property is True and while it is not docked, it also behaves correctly and does not shrink past its content. The UserControl also does not shrink past the panel while it is not docked.
But I want the panel to be docked to the bottom while still restricting the UserControls minimum width so that its content stay completely visible.
How can I achieve this?
Affect the Dock property at the time of creation of UserControl object like this:
UserControl myUserControl= new UserControl () { Dock = DockStyle.Fill };
I have a problem with UserControl that I'm crafting. It consists of TableLayoutPanel with another TableLayoutPanel in it with ListView inside. I want to make it resizable so that it will fit in left panel of my app and behave somewhat like Toolbox in Visual Studio. The problem is that my control doesn't scale when I resize panel.
UserControl is embedded in panel with Dock = Fill and Anchor = Tob, Left, Bottom, Right. Also all controls in it are made that way. How can I fix this?
EDIT: It's WinForms, not XAML.
Use a split panel and put your UserControl in the left panel and Dock.Fill it.
You're probably looking for the AutoSize properties on the TableLayoutPanel and the AutoSize ColumnType of that panel.
You can achieve something like a Dock = Fill by simply auto-sizing the table layout panel (GrowAndShrink) so that it will always fit your inner control.
Please post your designer code to see how you embedded the controls in which other control.
I suspect your resize problem come from your resizing strategy of control inside the TableLayoutPanel.
The table layout panel is tricky. Regarding the resize strategy you want to follow inside a cell of the table panel, the control in the cell have either to be Dock.Fill or Anchor = Top, Left, Bottom, Right.
Basically:
Il you want the grid cell to adapt to the size of the control, then have the control in the cell Anchor = Top, Left, Bottom, Right and set the row/column to autosize.
If you want the control in the cell to adapt to the cell size, use Dock.Fill on it and use a percentage or a absolute value to size your cell.
The behavior of the TableLayoutPanel is best described in the MSDN documentation.
