Resizing Controls At Runtime Not Using Anchor Or Dock
Feb 14, 2012
I have a code method that I wrote in vb6 that works on every screensize and resolution combo...however vb.net is not letting me do this. Here is what I do. upon form load at program startup I gather all of the data of the controls (height,width,top,left,font
size) prior to the form actually resizing and I store those in a listbox that is not visible. Then when the form resize is called I proportion all of the controls from their old positions versus the new form size.

I created a basic winform project where I want to handle all resizing without writing a single line of code. I set up controls using dock/anchor. They all work properly, until I add a custom UserControl. When I first press F5, the project works fine. However when I get back to the IDE some (but not all) controls which have anchor right/bottom are resized/moved into positions and sizes not previously defined. Some cannot even be restored as they are moved permanently below the container's boundary with coordinates above 2000. If I fiddle around and test the project many times, all controls with right/bottom anchoring will go haywire eventually.
If the custom UserControl has controls inside with right/bottom anchoring those also get resized in weird ways. Adding the controls again solves the problem temporarily. It is the IDE that moves these controls around since these movements are displayed in the undo stack right after I exit testing the project (however,undoing these steps only messes things up even more).I am using VB 2010 on Windows 7 x64.

From this forum I saw some discussions about form/controls resizing issue with different resolution screen setting. Most suggestions are using Anchor/Dock. My application's form has 10 group boxes and some buttons. In each group box there are 5 Text boxes and other more controls. I tried anchor and dock but couldn't make it work. My questions are -
1, How to re-size form and all individual controls as well?
2, If anchor/Dock are suggested, do i have to use both of them or just one? it seems to me there is no big difference between them.

we all know how to dock or anchor controls so that they resize themselves accordingly when a form is resized. It works fine till we have rows of controls on left and right size of the form. But what if have three columns (Columns as in visual sense. I'm not talking about any column control containing other controls) of controls? For example a form having a bunch of controls in the left side, a bunch in the middle and a bunch in the right. There may be a few more bunches in the middle. Now while resizing the form, I want the controls to resize accordingly as well as change their positions to make space for the previous bunch of controls that are resizing.I mean, while the user increases the form size horizontally, the controls of the second bunch should resize and at the same time they should move right because the controls of the first bunch are increasing horizontally too. When the user decreases the form size horizontally the same thing should occur in the reverse order.I can manage it somehow using nested splitcontainers but that's too cumbersome. I would like to know if there's some better way to achieve it, like setting some property etc.?

I am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel

Does datarepeater control has a bug? I tried to anchor a text box control inside the DataRepeater.Item, but it didn't work. At the property window, I set Anchor = Top, Left, Right. Anchor Right doesn't work properly.

When I compile my solution and execute the program and set the form in window normal, it behaves strangely. The grip is apparent, the mouse changes to the appropriate icon, but I cannot change the size of the window.

I am creating a form in vb.net and i want its size to change the form as soon as the user inputs the desired number of items. In my form I have two combo boxes: one for number of items and the second is for the choices, then when the user choose 5 items 5 text boxes will appear and if the choice is 25 then 25 text boxes will appear. Is there any way that I can change the form based on the input and number of text boxes?

I have a listbox and a panel. In my forms resize event, my listbox is always form1.width * 0.5 and then the panel is also, but it doesnt work very well. They overlap at a certain point but in theory, they never should. Is there something wrong with my logic?

I'm not going to post my code for my transparentlistbox class, but here is a link to it.It's been working fine as is, until early this morning when I tried to set a different size.[URl]..For the longest time I placed a normal listbox control on a form and resized that, setting a new public variable of transparentlistbox to the same size/location as the original listbox, setting the visibility of the original to false, and adding the transparentlistbox to the form (me.controls.add).It looked like this:
[Code]...
Now, since I've moved some buttons around on my main form, I resized the original listbox control to be wider (same height though). When I tested, the transparentlistbox (code didn't change still set to original listbox size/location), the size was that of what I had the original listbox set to, before resizing?
So, I commented out all of the custom drawing/paint events/etc I could find for the transparentlistbox and tested, still stuck to the original size. I stepped line by line debugging and verified that transparentlistbox1.size=listbox1.size indeed matched the new resized size (but didn't actually resize)?
Last I did was comment out the transparentlistbox.visible and put back the listbox1.visible and listbox1 does indeed show with the new resized size? I'm not quite sure what to test next?

I have a windows form with a groupBox and several controls ( textboxes, checkboxes, one grid, labels ) in the groupBox. I want to make the form resizable , such that the controls would resize themselves when the form is resized instead of overlapping each other.I tried docking and anchoring in several ways, but I am not able to achieve this.

I have two controls inside a user control. They are set to be anchored left and right in order too size with the window as it changes size. For some reason I'm having tons of issues getting this to work properly.
Particularly, when ever I build the project and the control reloads itself, these controls triple in size, and extend way off the control. If I re size them and repeat the process it happens again! Anyone have this issue or know what might cause it?

I have a basic windows form. I have one command button of the default size right in the middle of the form. I also set the anchors for the command button to keep it in the center when the window form is resized.The issue is when I maximize the the window form the command button remains in the center, but it has grown in size tremendously (almost taking up the entire form).I want to keep the command button centered when the form is maximized, but I also want to keep it the same size. Is there a property for the command button I am overlooking which will do this?

I have two DataGridView controls, with three buttons in between them vertically, in a VB 2005 form that need to be resized and moved around on a form resize.
The code below works, and does what I want. It takes the difference between the new size and the default size, splits the height difference between the two DataGridViews, and moves things around correctly.
What bugs me about it is that I've hard-coded the defaults into the ResizeEnd handler. How would I go about passing the default size so that I don't repeat myself?
Even better, is there a way to do it with anchoring, docking, and other stuff, so that I don't even need to write code?
Private Sub dlgShowAssets_ResizeEnd(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.ResizeEnd
Dim defaultWindowSize As New System.Drawing.Size(759, 619)

I have a form that sits on the user's desktop. It's only purpose is to display specific information about the computer. The layout is basically setup like this:
[Code]...
I want to be able to give the user the option to display whatever data they choose. In doing so, I'd like the form to resize itself based on the how many labels are in the form and for the labels to align vertically.
Can anyone point me in the right direction? For the form, I was thinking I could get the location of the last label and offset it's size by the location, or something similar.

I have a development system and two test systems. My development system is Windows 7 (64 bit). My two test systems are Windows XP (x86) and Windows 7 (x86). I have created a program on the development system mostly in VB.NET 2008 and deployed it. It looks nice on the development system and on my Windows XP system, but when executing the software on my Windows 7 (x86) system, all the form sizes and components somehow grow. To investigate the issue, I moved over the entire project and opened it on the Windows 7 (x86) system to find that the sizes have somehow changed in the designer there as well. I opened up the .Designer.vb files and the sizes there all seem correct. Then I go to the IDE and the sizes are larger than they should be. For example, I will set a form size to 532, 217 on my development PC then it will show up as 709, 267 on the test system. I tried putting in code on my form.load event to set the size to 532, 217 then re-deployed it, but again, it executes and the form is too large.

I have a project running in my old computer. It has panels,textboxes,labels etc. It occupies the full screen when running.I bought a new computer with a widescreen format. When I run this project it only occupies 2/3 of the screen.
What properties of the controls must I use so that I can run this program in any size computer and still occupy the full screen i.e the size is proportionately resized depending on screen size.

Where is the best place to resize a control on a form when a form is resized?....I'm currently using the Form1_SizeChanged event and seems to work ok. Also is there any need to check in the forms resize event if the form is in a minimized state before resizing controls?.,.. in VB6 if you try to resize a control when the form is minimized you get an error, but I don't see that happening in BV10 Form1_SizeChanged event, does VB10 automatically ignore resizing controls when a form is minimized or something?

First off I'm using the Extended Webbrowser control from: [URL]
I use the Webbrowser control to access an ESRI web based mapping solution. When the ESRI map is loaded into an IE browser and the browser is resized then the map control resizing accordingly. When my Webbrowser control is resized the map webpage is not resizing properly.
I don't even know where to start with this problem. Is there some event that's not firing in the website? I can't simply refresh the whole website because the user may have panned and zoomed around. I want to just tell the website that the container control (Webbrowser control) is resizing now.

In my windows application I have a normal panel inside a flowlayoutpanel In this normal panel, i have some input controls(e.g. labels, textbox...) I have set the anchor properties thinking that it will auto-resize when I resize the window. But when i tested it, only the flowlayoutpanel auto-resize itself, as i can see that the sroll bar has moved further toward the right... the contorls in the normal panel didnt move at all.

I've got a set of controls in a line inside"FollowTableLayoutPanel1", contained within "TableLayoutPanel2".I have them resizing according to the position of the mouse cursor; the closer the mouse cursor is to the vertical centre of the control, the larger the control is. Because FollowTableLayoutPanel1 has its anchor property set to "Top", it recentres itself in TableLayoutPanel2.It is possible for the recentring of FollowTableLayoutPanel1 to move a control one pixel further away from the mouse pointer, which causes the control to shrink, which causes FollowTableLayoutPanel1 to recentre, placing the control closer to the mouse pointer, which causes the control to grow,which causes FollowTableLayoutPanel1 to recentre, which moves the control further away from the mouse cursor, etc., etc., etc.The end result is that the whole setup judders and wobbles, constantly resizing.Full example code is provided below,and can be pasted directly into Form1 of a new project. Positioning the mouse cursor to correctly show the problem is left as an exercise for the reader :
Public Class Form1
Private Sub myInitializeComponent()
Me.components = New System.ComponentModel.Container
Me.TableLayoutPanel2 = New System.Windows.Forms.TableLayoutPanel[code].....
