.net - FlowLayoutPanel - Automatic Width For Controls?
Mar 22, 2011
is it possible to make the inserted items in FlowLayoutPanel automatic size of the FlowLayoutPanel? Here is an example:
A form with 1 FlowLayoutPanel and 3 buttons inside:
if I resize the form, the controls look like this: they arrange "left to right"
What I want is this: The controls should have the width of the FlowLayoutPanel:
how to do this? I changed the FlowDirection and played with the Anchor property but with no luck.
I could of course Resize the controls in the FlowLayoutPanel_Resize event, but I want to add about 500 usercontrols - I tested it and it is slow.

I have a flowlayoutpanel, and a bunch of controls inside it.
I would like to actually SORT the controls, depending on some values.
For Example:
The FlowLayoutPanel has 4 Controls:
Each control has: Name (string), Maker (string) and Rated (integer) values.
So what I thought of was:
Dim
s As
New
SortedList

how I can expand the border size of a listview control. I would probably need to change the color of it as well.

been trying to find examples of how to go about auto sizing the controls i have within a grid control if the users screen is larger than the default size.Currently i am unable to resize the controls when i enlarge the form. Is there any code currently that can find all controls inside the grid and resize them on the fly when the form is resized?My current code is:
<Window x:Class="Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

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'm writing an app that pulls information from a DataSet as a one-way thing (e.g. the datasource populates a listbox, but for selection purposes only -- the user cannot change the list values). My problem is, when I select something from the listbox, all of the other listboxes change too, as if the control is telling the others "Update your contents to display what is in row 5"
[Code]...
I then use the IDE to bind lstOne and lstTwo (both listboxes) to datInfo, and use the DisplayMember to bind lstOne to colOne and lstTwo to colTwo.When I run and click on a value in one listbox, the other one follows suit. For example if I click on "One Three" in lstOne, lstTwo displays "Two Three". I expect to click on "One Three" then be able to independently set lstTwo to "Two One"
This seems counter-intuitive, so is there a way to do what I'm after from the IDE, or will I have to do it all from code?

What I am trying to do is fill the contents of the datagridview with the cell contents. There are two ways to do this.
1) Either set the DGV width to the cell contents width, or
2) Autoadjust the width of the cells to the width of the DGV.
how to implement either of these two approaches?

This Winforms app has a toolStripComboBox within a MenuStrip container that displays Culture Info languages.The toolStripComboBox's width is not expanding to accommodate the size of the string. The strings are dynamically added to the combobox from underlying code. How do I get the comboboxe's width to expand? Below is an image of the'too narrow' combobox and below that the Properties for the combobox.

In VB.NET for the combo box, I have set the autocomplete mode to "SuggestAppend" and autocomplete source to "ListItems". Its working as expected. But the width of the autosuggest dropdown box is not same as that of combo box and so it looks weird.I tried changing the value dropdown width property but it changes the value of normal dropdown box (seen after clicking down arrow on combobox), and not the autosuggest dropdown box.So what code or property needs to be set to make autosuggest dropdown box the same width as that of combobox width?

I have a drawing program written in VB6 that is capable of printing very thin lines to a laser printer. In VB .net, even though the pen width is set to 1, the thinnest lines are way too "thick". The equivalent line width in VB .net using a pen width of 1 is about the same as the DrawWidth = 4 in VB6. So, my question is, how can I print very thin lines to a laser printer in VB .net?

how to adjust the width of the listview and also the datagridview to the width of the form.Because I want it to be able to follow the form's width and when maximized the form, the listview or the datagridview will also be maximized to the form's width.

FlowLayoutPanel will not scroll. The mousewheel event will not fire. The scrollbar appears when it is needed. I thought it was a focus problem, but the panel responds to all other mouse events.

I have been dynamically adding user controls to my panel. This user control has a height of 105. If I have my FlowLayoutPanelwidth to only show 1 "column" of controls, it will only display 296 of them. The rest of the controls are grayed out at the bottom of the flowlayoutpanel. If I widen the flp to allow 2 "columns" of controls, I can see 592 of them, with the remainder grayed out at the bottom. I have gone in and resized the user control to make it shorter in height, which works in some respects (i.e. it works when I have two columns, but not just 1), and can go forward with this work-around.
So, I guess my question is, why does the FlowLayoutPanel behave in this fashion? It seems (based on what I saw) that there is a limit to how much data the FLP will show at one time.

[code]I can't figure out how to make those pictureboxes in flowlayoutpanel clickable. Any example will do - opening it in default picture browser, using it as panel background or using it as a picture for separate picturebox - anything will do - I simply do not know how to get the file name assiciated with the particular picturebox in the flowlayoutpanel.

I normally hate posting to these forums - but I've reached my wits end. Before posting I've searched all over the internet and no one seems to have come up with the solution.
I have a flowlayoutpanel with a number of buttons in it - I simply want to be able to click and drag a button and reorder it. Sounds simple but its driving me mad! I've spent hours searching the net for an answer but with no luck - the closest I got was a guy showing how its done in C#....No clue how to translate it.

I've got a form with a FlowLayoutPanel (flpPhotos) containing several PictureBoxes that are created on-the-fly based on the photos in the specified directory. What I'm trying to do is right-click on any photo and select an option to delete that photo, view a larger version, etc. When I right-click on an image and select Delete in the PictureBox's ContextMenuStrip, I'm getting a NullReferenceException in the deletion method. When debugging, _selectedImg is Nothing, for reasons I don't understand, as a reference is saved to it in the selected PictureBox's MouseDown event. Incidentally, _selectedPB is also Nothing.
Private _selectedImg As String ' The file path of the image in the selected PictureBox
Private _selectedPB As PictureBox ' The PictureBox whose ContextMenuStrip has been instantiated

I am attempting to load all images from a directory to a FlowLayoutPanel. I am using the GetFiles() method to retrieve the files with a filter to just retrieve JPG files. When I run the program, it returns 'Conversion from string "*.jpg" to type 'Integer' is not valid.' exception. The offending line of code is:
For Each foundFile As String In My.Computer.FileSystem.GetFiles(FolderBrowserDialog1.SelectedPath, "*.jpg")

I have small program that allows the user to add clickable pictureboxes to a FlowLayoutPanel. The .Tag property of these pictureboxes contains the link that the user has added to them. I have been doing a lot of research on ways to save forms and data in VB and am kind of overwhelmed with all of the options to choose from. Is there one best way to save the form and data?
I'm pretty sure I have to use XML Serialization in order to properly save the pictureboxes with their respective properties kept intact, but would like some input from the pros.

I've been working with controls and a flowlayoutpanel (see image) to provide a user a good looking "Menu" from a list of items on my server. Anyway, since there will be a lot of custom controls (The boxes inside the flowpayoutpanel) I am trying to save them some how on the user's settings so it won't have to request the list from my server every time. Thus making the program load faster and saving my server a heavy load of bandwidth. I'll go into a little more detail what the controls consists of. Its mainly just labels, pictureboxes and some hidden strings, when the program gets the list of all items from the server it will grab and separate the info for each control.
So the main question here is, is it possible to save a control and load it again even after the program is closed / reopened? The first thing that came into my head was to write a code on exit, that will go through all the controls in the flowlayoutpanel, get the label's text and picturebox's image locations, etc.. save all that info to a setting, and on the next program startup, it will load the setting instead of fetching the data from my server.

I am currently implementing a drag and drop feature to reorder a set of user controls that I have put in a flow layout panel. I've turned off wrapping and the flow direction is from top to bottom. Here's how I've implemented the drag and drop feature itself:
UserControl_MouseDown event:
1) Get the mouse offset from the upper left corner of the UserControl
2) Remove the control being dragged from the FlowLayoutPanel and put it in the form
3) Calculate the rectangle relative to the form of the FlowLayoutPanel
UserControl_MouseMove event:
1) Using the mouse offset of the UserControl, figure out the UserControl's new location on the form
2) if that location is outside of the FlowLayoutPanel's rectangle, change the calculation to move it to the edge of the FlowLayoutPanel
3) Move the UserControl
UserControl_MouseUp event:
1) Find the underDrop control (the UserControl under the UserControl that's being dragged)
2) Figure out if the dragging UserControl should go above or below underDrop
3) Add the dragging UserControl to the FlowLayoutPanel and set it's index.
This is working beautifully! It reorders just fine.My issue is when there are more controls than will fit in the visible area. I have AutoScroll set to True, so the scroll bar turns on. When I drag a control to the bottom I turn on a timer that periodically adjusts FlowLayoutPanel.VerticalScroll.Value depending on if the UserControl is at the top of the FlowLayoutPanel or the bottom.
When I move my mouse left or right, the UserControl (who's parent is the form) still gets moved left or right. When this happens, FlowLayoutPanel.VerticalScroll.Value is reset to what it was before I started adjusting the scroll. On top of that, even if I'm careful to move the mouse only up or down back inside the FlowLayoutPanel's rectangle, when the UserControl gets moved, FlowLayoutPanel.VerticalScroll.Value is reset again, so I can't drop it where I want to.why move a control over the FlowLayoutPanel would reset the VerticalScrol.Value? Is there a way to stop this? Is there a better way to scroll inside a FlowLayoutPanel?
