I have here another question. I have a panel with about 20 different panels inside of it. There is a "mouse move" event for panel 1, How could I make is so if the mouse is over 1 of the 20 different panels, Have it display the panel name? I would paste source but that's why I'm posting here.
View 1 RepliesI'm trying to make custom ListBox with some graphics. Base is ItemCollection - each item contains Panel, 2x label and 2x picturebox. What each panel have to do:
- Change backcolor on MouseEnter and set color back when MouseLeave occurs.
- On MouseDown(LMB) - Panel stays "selected" - different color.
Problem: I can't access multiple panels at a time(and I need to), just one via sender as in function. Of course, I can do it hacky way, but I want to do it effective and regular. Is ItemCollection the right solution or should I do it just like an array of panels? Also I want them in one "box", ItemCollection is good for it.
Second "problem": I need to make labels "merged" in panels, when i MouseEnter them(labels), background color on that panel sets to my default color. when i MouseClick them(labels), nothing happens (need to "select" parent panel). It can be again fixed with hacky way, just disable labels - but then the colors of labels are unchangeable.
To save from using several different forms in programs. I'd like to make just a few panels to represent each one. Then when I need to display one I just set it to visible or not visible.
For example, a quiz program. The 1st 10 questions are on one panel, the 2nd 10 are on a 2nd panel. They are both identical except different questions.
The problem is, when I try to put them both on the form, they have to be in different areas or else one will go inside the other. How can I keep several panels on one form without them going inside each other, in other words how can I keep them separate?
How can I create a GUI in vb.net similar to the one above?i.e.there are "buttons" on the left which changes the main window when they are clicked.One way I thought of is create many panels overlapping and show/hide them when a certain button on the left is clicked.
View 2 RepliesI would like to have two different panels (with associated buttons, textboxes, etc.) on the same location on a form. Is this possible and if so, how do I go about doing it? I need this to control two different boards with the same application.I realize it would be difficult to edit the form if they are on top of each other. Is there a way to place these panels apart while designing/coding, but have them located in the same spot on the form during runtime?

View 2 RepliesI have 14 panels in my form, the user then input a number in the textbox. Then this textbox will now determine how many panels will be enable. My formula would be, userinputtextbox/0.5=panels to be open. Example: 3/0.5=6.
So far this is my code:
for x = 1 to UserInputTextbox.text
CType(Me.Controls("P" & x.ToString ), Panel).Enabled = True
next
But I got this error: Object reference not set to an instance of an object.
Is it possible for the monitor's screen to be split into multiple panels using vb.net? What I'm thinking about is I have two or three panels in the screen, the first panel is running a powerpoint presentaion, the other has an excel worksheet open and the other has a windows and fax viewer open something like that. Is it possible to do this on a windows form application project?

I have a VB.NET (2005) application designed by my boss that uses a over 100 input and display controls (textboxes, comboxes, etc.), many with labels associated. My boss asked me to set the tab order, and then trap keypress so the user can use enter to navigate controls. I have 2 apps like this to work on.For the tab order, I could not use the View/TabOrder feature, since there are so many blue little tabindex popups showing, that I can not see any of the controls on the form to click. I tried clicking 'through' the popup with some success, but it still did not give me the tab order I wanted. The tab assistant that came with CodeSMART did not give me the result I wanted, either, so I could use it.
The controls on this usercontrol are spread among many groups, which in turn are spread among several splitcontainer panels. The 1st panel in the main splitcontainer has 3 main groupboxes which are selected via a toolstripbutton ( which sets the desired groupbox to visible and turning the others to invisible.) Example:
Private Sub ShowMainPanel()
'Note: Panels are groupboxes
Me.MaterialPanel.Visible = False

AM trying trap specific events for some controls on a form. i tried this, but its not fireing the events

EDIT I found out that am placing the control in multiple controls, on the form is a panel, inside the panel is different groupbox, these group boxes have the controls am trying to trap their events
I have multiple queries that I need to run when a user clicks a button but they are all separate queries. Can this be done?
View 1 RepliesI am using VB2010 Express to create a Windows Form.
I have been able to add an event handler to a single textbox to respond to the ".Leave" action.
Now I want to take multiple textboxes and use them as a single control and use the same event handler.
Eg. If TextBox1, TextBox2 and TextBox3 are grouped as a single control nothing would happen in those boxes until focus went to any other control on the form.
I have many textbox controls and they are named as txt1.text, txt2.text, txt4.txt etc.I want to raise the event "Leave" when txt1.text leaves or txt2.text leaves.but with a single handler.

There are two panels A and B in a form horizontally, same size.

View 7 RepliesI have a form which has two panels each containing there own controls (Pnl1, Pnl2). By Default I want Pnl1 to show and Pnl2 to be hidden which I have set but I want Pnl2 to sit ontop of Pnl1 so when Pnl2 is selected Pnl2 is Visiable and Pnl1 is hidden. Therefore Pnl2 and the controls sit in the same place as the controls in Pnl1. I have got everything lined up but as I move Pnl2 over Pnl1 to sit ontop, Pnl2 is moved into Pnl1 and becomes a Panel within the Controls of Pnl1. Therefore when I hide Pnl1 everything is hidden as Pnl2 is part of Pnl1.

View 2 RepliesI am trying to stack panels on top of each other, but they keep becoming children of the one I put them on top of. I am stacking three panels.

They are all exactly the same size and same position
View 2 RepliesIm working to develop an application thats going to run on some not-so-good as performance PC's. The application is done in VB.NET and i encountered some obstacles during my work.
The idea of the application is to allow the users to slide through some pages when they click with the mouse and drag (while the left click is pressed) to right (for browsing to the previous page) and to left (for browsing to the next page). Every page contains 4/6/9 panels with 4/6/9 pictureboxes with some gifs as images.
The issue is that when the user drag with the mouse to browse to a page, the panels and the pictureboxes jerks around when they are moved.
Here is the code that handles the slide part
If i + speed < 1024 Then
For j As Integer = 0 To nrOfGamesInTotal - 1
totemGame.gamePanel(j).Left = totemGame.gamePanel(j).Left + direction * speed

View 1 RepliesI am looking to make an application where panels might seem to be very heavily used. Is it recommended not to use them for large item management?For instance, I want to have a menu with flat style button.

From there, for each option clicked, it will display a panel on the right with various results for the specific criteria selected.
View 5 RepliesI have an application in which the windows form has 3 panels. Under some circumstances, controlled by the User I want all three panels visible, in other situations I want one of the panels not visible.
The program works if I use the code:
Panel1.Visible = False
Panel2.Visible = True
The program also works if I use the code:
Panel1.Hide
Panel2.Show
Is there some advantage or disadvantage to either of the two approaches?
