I want to set the value of x that is the location of the controls inside a selected usercontrol at runtime. i want to set it to be 0 when there is no control on the usercontrol and i want it to be x += control.width. how can i do this, maybe how can i detect that there is a control inside the usercontrol.
View 8 RepliesI have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.
View 12 RepliesI have a block of code below that allows the user to create new buttons at runtime at the click of the right button at runtime.But i am wondering how to detect the selected button on the main form and then the user can delete the selected button at runtime.
The other thing the user can do is also to drag the button around the win form when in runtime. Cause i'm new in VB and i am exploring this part. the code that i have is here and it is created by one of the member in msdn.

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?

View 5 RepliesI am putting together a simple multiple column listbox. I call it Gridbox.The intent is to make a lightweight grid control mainly for displaying lists with columns. Minimal cell access i supported.
I wrote it with an IntegralWidth as well as an IntegralHeight.Of course I cannot support the Integral Width if there isn't at least one column in the Columns collection when the control is initialized.
To this end I call a Column Add() method in the UserControl New() Event.
So that one Column will be present when the control is placed on a form.
For some reason the New() UserControl Event is firing twice. So I end up with two columns not one.
I was under the impression that New() only fired once when the control was intialized. Where would
I put the code that creates the desired column if not there?

[URL]its a free hoster, so you have to wait 10 seconds.First here's the steps to replicate, then I'll explain what the problem is:
(1) Create a System.Windows.Forms.UserControl and add a button to the bottom-right hand corner. Leave the button anchor as default (top-left). Add some more buttons dotted around so that you can see that they scale correctly.
(2) Add the UserControl to a form in the construtor, after the InitializeComponent call.
(3) Run the form.
(4) Increase the form font size some way (eg click a form button).
All the controls within the usercontrol scale perfectly but the usercontrol itself doesn't. It's width and height are increased by way too much. Look at the margin now between the button at the bottom-right hand corner and the usercontrol.To correct the problem, the usercontrol must be added before the InitializeComponent call.If it wasn't possible for me to add the usercontrol before InitializeComponent, is there any way for me to correct the scaling?
Well the title pretty well describes my problem. Here is a little bit more detailed description of my problem: I am building an application with a TabControl, which I populate at execution time with TabPages. In my first version of the code, these TabPages were filled with a children ListView. The ListView was also created in code, using AddHandlers to link it to the DragEnter and DragDrop routines. Everything worked very well... Now as I need some other controls on every TabPage, instead of creating every single control in code, I have created a UserControl containing a ListView and a few Buttons, which I instantiate for every new TabPage. The problem now is that the DragDrop event is not raised anymore

I have a Form1 where i can add usercontrols during runtime. I draw their appereance in the OnPaint event using the GDI+ engine. The greate part is that i want to be able to resize these images during runtime wich goes pretty well now cause i draw points in percentage of the control. Unfortunetly it is very difficult to draw nice images/drawings ect with the GDI+ engine. Is there any other way in doing this?

How do I check whether the controls in a usercontrol contain any value?
I have created a usercontrol called ctlCustomerAddress and I want to create an address record in the database if only I have the values in the textboxes.
am trying to make use of inheritance to keep consistency in my user control appearance. I created a usercontrol to use as my base design, as a platform to link to a tab as acontainer. To this I added a few framing visual items like a header panel andsome labels.I then created another usercontrol that inherits from my base control, with the intention of adding the necessary items to this derived control to build it into a complete functional usercontrol that I can associate with a tab on my main form. I want to keep the visual appearance consistent across all similar derived controls. Then later if I change the design of the base form, this flows through to the derived controls.

VB.NET 2.0 Framework..I developed a control that implements IExtenderProvider in order to attach to controls and display a form for translating of the text of that control.This works great on regular controls on the form but the IExtenderProvider is not attaching to controls on UserControls by default.Is it possible to modify the UserControl or my IExtenderProvider control to enable it to attach to controls on a UserControl?

View 12 RepliesI researched this and found I had to use something called "ScreenToClient" [URL]...what I want to do is to have a picture box that I can just get the coords from easily (for example 0,0 bottom left hand corner)
So how do I get that to work? (im guessing something like comparing the picturebox size to the form size then working it out but im not quite sure how to do that.)
I am trying to make a small control that has a picturebox and a few labels that can be dragged on the form it is placed on. The control was easy, and I can drag it fine when the mouse is down on the control, where there are no other controls, like not over the picturebox or labels.
When i try to click and drag the user-control and the mouse is on the picture box or labels of the control the mouse down event is not detected. I am hoping someone can tell me how to pass the mouse-down event from the controls on the user-control so the form I place it on detects the mouse down even no matter where on the control i click.
