I have a C# winforms application that has table layout panel. The panel is set so that there are two columns, with a 75/25 % split. In the larger section is a docked panel that holds some controls, while the smaller section has a docked panel with a single label. We push a wall of text to the label on the right and it is getting jammed up ugly.
I've adjusted the controls on the large section and recovered some space that I want to give over to the label panel. The "Completed" and "Inspected" labels and dropdowns are not in use, and set to invisible currently. I used designer to adjust the split on the table layout panel to be 65/35 %, but the docked panel and the label didn't change position on the layout.
What I want to happen is for the table layout panel to have a larger portion of the split given over to the label and the label to fill the new space when text is set to it.
The results of my efforts haven't gone very far. I adjusted the split %, but the label looks unchanged. It seems to be the exact same size it was before making changes. It looks like the label maintained the same position as well, stuck to the right hand border of the panel. The label definately isn't extending past where it originally ended/started with the 75/25 split.
The sub panel and the label are set up to fill and anchor top/left. The panel is docked to the table layout panel. I was under the impression that the docking and filling would account for the change in the split, but I'm wrong about that I guess. I feel like this whole problem has some root in these settings, but my tinkering with them hasn't changed anything that I can tell.
Following the instructions provided by LarsTech, I adjusted the settings on the layout panel to be absolute pixel value on the left hand side and 100% on the right. I then set the panel anchor to top, right. I set the label itself to dock = fill. The label is now stretching across the entire area covered by the blue arrow.
Thanks again. Would give a +1 to your comment if I could.

I have this form, where the light blue is a flow layout panel and the white is a panel inside it.
.
It looks like this when running:
If you look carefully, you can see a small border around the edge of the white section.
Why doesn't the panel fill the space inside the flow layout panel? I haven't done any coding; I just saw a guy placed the panel over and it automatically filled the space.
It seems that the margin was bugging it. I fixed it by setting the margin to 0, it was 3 by default. Thanks to Jimi.
You should set Panel.Dock to Fill, then it adapts it's size automatically to the flow layout panel. Default for Dock is usaually None, in this case it always keeps the same size.
On my form I have a Panel control that contains a PictureBox control and a Label control.
The panel is not visible in the image above but it's basically the area around these two controls.
I have set the Anchor property of all these three controls to Top, Bottom, Left, Right so that they follow their parent container's re-sizing behavior.
The L abel control (postbagfolderempty) works properly but the PictureBox (EMPTY!) does not seem to be moving from its original position.
Is there an additional property I need to set?
Update: I changed my PictureBox's AutoSize property to None. It has started to move, but as I try to enlarge my form, it starts sinking into a white area (image below).
Make sure your PictureBox doesn't have SizeMode set to AutoSize.
Anchoring changes the size, if it's autosized it won't change anything
Also, make 100% sure your PictureBox is actually a child of the panel. It's easy to check: select it on the designer and press Esc, it should select the panel.
Update
As per the comments, seems the problem is that you are anchoring to all the sides (thus producing the scaling of the control).
If you want a panel that scales with the form, and controls within the panel that are centered but not scaled along, then anchor that panel to all sides, place the controls inside the panel centered in the designer, and set their anchors to None, that way they won't scale, and since they are not anchored, they will move along when the panel scales (but they won't scale with it, which -seems- it's what you are aiming at)
I have been looking around for a solution to this but fail to find it anywhere.
I am currently making a management program for an organization which handles kids with special needs. They need to keep track of a lot of data, etc.
I have placed the data in a GroupBox with TableLayout using Drag N' Drop. However the elements do not align. The left side seems to be docked in the upper left corner of a cell while the right side seems to be docked in the lower right corner of a cell.
How would I solve this so they are both centered in their respective cell?
The alignment of controls placed in a TableLayout cell can be influenced by the anchor setting of these controls.
You can align your controls Middle-Center by setting the Anchor property of your Labels and TextBoxes to None.
I've create a c# winforms form,
It has a bunch of labels positioned and a flowlayoutpanel.
on certain occasions i set one of the labels and the flowlayoutpanel to visible =false.
As a result i want all labels beneath them to be pushed up - at the moment there is a gap where they were.
Also, I'd like the flowlayoutpanel to grow and shrink depending on the number of items it has.
at the moment it is just the size i set it to be in the designer.
please can you help with these 2 issues.
Thanks
If I got you correctly, I would suggest using a TableLayoutPane with two rows. The top row will contain a docked panel with all the controls that may be hidden. The bottom row will contain a docked panel with all the rest.
Set the top row's SizeType to AutoSize and the bottom row's to 100%.
When you want to hide the controls, set the top panel's Visible property to false. Now, because the top row is AutoSized it will shrink to nothing, causing the bottom row to "jump" up.
The TableLayoutPanel does the pushing. Maybe you can use that if there is no better answer in next time.
First problem:
You may use some simple panels to divide your form, give them the dock.fill property. when you'll hide a panel programmatically, the other panels will fill the empty space left.
Second problem:
You have to set the Autosize property to true.
How might I design a UI in C#/WinForms which happens to contain several different control types such that only the ListView control gets resized if the user resizes the window?
There are two primary ways to make a control automatically resize based on size changes of the parent container (a Form in your case):
Set the Dock property of the control to DockStyle.Fill.
Set the Anchor property to "Top, Bottom, Left, Right"
Use the Dock property with Dock.Fill
The advantage of this method is that it takes the entire control and tells it to always fill the entire client area of the parent container (in your case, the Form client area). That's useful if you want to do something like fill a Form with a ListControl or TreeView or something like that. But it's not as useful if you want to scale a single control while using other controls (as you indicate is your need). In that case, you would need to set the Dock property on those other controls to DockStyle.Top or DockStyle.Bottom to have them float above or below your main resizing control.
That's a hassle and it also limits the layout options of the other controls. You can mitigate that problem by docking two Panel controls, one at the top and another at the bottom of the Form. Those panels will remain in fixed positions while the middle area (with your DockStyle.Fill control) scales with the parent Form. You can then put any controls in any layout configuration in those "header" and "footer" panels.
This kind of composite form-building using docked panels is incredibly powerful. Quite frankly, it was game changing in .NET when they introduced this with .NET 1.0 WinForms.
Use the Anchor property with "Top, Bottom, Left, Right"
If all you want to do is have a single control on a form scale, while others stay "stuck" to the edges, use the Anchor property. For the controls that you want to stay at the top, set the Anchor property to "Top, Left" (the default). For controls that you want to stay at the bottom, set the Anchor property to "Bottom, Left". For controls that you want to grow in width with the form/dialog (such as a single-line textbox control), set the Anchor property to "Left, Right" (and set Top or Bottom depending whether you want it move as the top or the bottom of the dialog changes.
And if you want a control to resize in all directions with a Form, set the Anchor property to "Top, Left, Bottom, Right". Very useful for "main control" type of things, such as a dominant listbox, tree control, or multi-line textbox.
For what you need, don't mess with the AutoSize or AutoSizeMode... those properties control how a control changes size based on its own contents, not how it resizes based on its container's behavior. Think of AutoSize/AutoSize mode as inward looking, while Anchor/Dock are outward looking. You get some very bizarre behavior if you use both sizing methods at the same time. Generally not useful.
Dock the ListView to all four sides of the form, and the other controls to 2 or less.
There is a property on controls called "Anchor" (in "Layout" category) if you set this to "Top, Bottom, Left, Right" it will maintain margins between control and its parent container causing it to resize as container changes size.
But if only one of anchors along one axis is enabled (e.g. "left", but not "right") it will move the control instead, again, preserving locked margins between the control and its container.
In short : exactly what James said, except it is "Anchor" not "Dock" property. Dock is similar but not exactly the same.
IF you put the ListView in one panel of a SplitContainer and put the remaining controls in the other panel you can restrict the growth of the second panel by setting the min and maxsize.
If your ListView is docked Full then it'll take all the increase when the form is resized.
What if we have multiple controls in the form?
For example: If a form is used to generate some result in a grid with respect to the data entered in couple of text-boxes or combo-boxes, etc.;
And we want them to resize/realign accordingly and not overlap each other (as it happens when using the dock-fill), especially with the grid-view or similar control in context.
