FlowLayoutPanel Not Showing All Contents?

Jan 26, 2012

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.

Showing Contents Of String Array To Single Label

Jan 12, 2011

I got a string array & I need to show the contents of it to a single label. It acts like a clock. The thing is I tried with everything I could but I failed. This is the code I've been trying. Its in vb.net. And theres a thread running to slow down the loop so I can display the contents in a label for 2 seconds.

Dim j As Integer
For j = 0 To readText.Length
label.text=readText(j)
Thread.Sleep(2000)
Next

VS 2008 - Showing Entire Contents Of Items In ListView Tooltips

May 18, 2011

I can't claim credit for this code but I think it's cool. It will show the entire contents of an item in a tooltip even when the columns are truncating it. Drop a tooltip and listview container on your form with the default name.

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListView1.Clear()

FlowLayoutPanel Will Not Scroll?

Sep 4, 2009

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.

Clickable Picture Box In Flowlayoutpanel

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.

Flowlayoutpanel And Repositioning Objects In It

Jan 13, 2011

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.

.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.

Accessing The Selected PictureBox In A FlowLayoutPanel?

Nov 8, 2011

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

Save Form With Pictureboxes In A FlowLayoutPanel

Feb 1, 2011

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.

Saving A Control (Custom) From A FlowLayoutPanel

Aug 6, 2011

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.

Scrolling During Drag And Drop In A FlowLayoutPanel?

Nov 27, 2009

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?

Control Can Exercise Over A System.Windows.Forms.FlowLayoutPanel?

Oct 23, 2009

I've been working for several days on a GUI where a lot of individual data elements need to be displayed side-by-side and wrap to the next line when they overflow; the goal is to not have to explicitly design an individual 'row' element with a set number of elements for this purpose. The FlowLayoutPanel seems great, except...

I need to be able to determine how many elements are on each line (dividing the width of the control by a predetermined value indicating width of child controls does not work); I need to be able to determine how many elements will be on each line (I may need to put 4 elements on line 1, then auto-wrap, then 8 elements on line 2, then auto-wrap, then as many elements as can fit on line 3 before autowrap, then 16 elements on line 4, etc); and finally I'd really like to put a 'line header' at the left margin and a 'line footer' at the right margin, where for example the line header contains a line number and the line footer contains the number of elements on that line.

If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

Bind Control.Text Property To Control Position In FlowLayoutPanel?

Jun 6, 2012

Is there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.

If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.

Handle Value Change Of Control Inside UserControl Inside FlowLayoutPanel?

Apr 30, 2012

I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.

I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?
