I'd like to design a Winform with expanding controls if that 's overly complicated. The idea is that I would have rows of information, each with an "Expand" button. On pressing the button, the rows underneath the selected row would move down and the controls that are associated with the selected row (some textboxes/ dropdowns etc) would appear. Vice versa when you click the "Hide" button.

basically i have a form with loads of controls. So many infact it stretches the whole hieght of my screen.I only need half these showing since the rest are just a sort of 'log'I have seen ti done loads, that only the controls i want to show at start up are displayed then when some one hits a little button in the bottem it expands the rest leaving them showing to.
View 9 RepliesI have a form that searches a db. Some searches will always result in one row of data, others might return multiple rows. I want to have the data from a single row shown in text boxes and the multiple rows show in a datagridview is it possible to hide/show those depending on the amount of rows.

I have a bunch of controls on my form and am wondering if I can hide some so it doesn't look so cluttered.I only wnt to hide them on the designer though and not at runtime. Any way to do this?
View 7 RepliesI am developing a WinForm application using VB.NET (I am fluent in C# as well, so post in whatever language) and have run into some trouble. I have an image on my form that I would like to expand when clicked on. I have all that logic set, but I want that when it expands, the user has to click on an 'X' in the upper right corner of the PictureBox to close the expanded image. While the image is being displayed, I don't want the user to be able to interact with the rest of the UI on the form.
Basically I need something along the lines of (pardon me for switching to HTML but I know this works there) creating a div that covers the whole screen, making it opaque, putting another div on top of that, and then putting the image and the 'X' button on top of that. I have tried using opaque forms (didn't work), and panels with a transparent backcolor (didn't work either). I've resorted to taking a screenshot of the form, setting it as the image of a PictureBox, and putting the PictureBox on top of that. However, that seems like way to much overkill.
My current layout is MainForm -> Dynamically create new Form and add it to Main Form -> Add PictureBox to Dynamic Form and set its image to be a screenshot of MainForm -> Add a PictureBox on top of that PictureBox and set its image to the expanded image that I want
I'm having a weird bug with a TabControl that I've never seen before. Here's what I got:
A TabControl with 3 tabs. The first 2 tabs have an inherited DGV on them, and the third page is like a options page. The 3rd tab has a bunch of labels, comboboxes, checkboxes etc...
Whenever I play/start debuggings/run the app the controls of the 3rd page turn "invisible" on the design view. They are still shown in the app. Here are two pictures showing what I mean:
This is what the designer looks like BEFORE I run it: This is what the designer looks like AFTER I run it (Running app on the right): I've tried building/rebuilding/cleaning and nothing. If I close the solution and VS and reopen it, it will show but that's a pain to deal with.
Assume you have controls A, B, C, D and E all with a Visibility property. You also have states 1,2,3,4,5 and 6 in which various combinations of your controls would be displayed. Currently this is being handled by switch statements for each state: i.e.
Select Case PageState
case "1"
a.visible = false
b.visible = true
[code]....
As you can imagine, this becomes a pain as every state needs a show/hide statement for each control. How can I refactor this so that adding controls and/or states becomes trivial?My first instinct is to extend the control and add a collection of states that it should display for but this sounds like overkill.
Edit:I was deliberately vague in my question in case this has other implications. In my current instance the "controls" in question are ASP Panels. Does that change anything?
Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
View 1 RepliesI have three forms: A, B and C. Upon a button being clicked, A displays B. Similarly, B displays C. Both using the ShowDialog() method.
However when I use the Hide() method (inside a Button Click event) on form C to close it, form B also closes. Why would this be? As far as I can see, it shouldn't be doing this. I certainly didn't write any code to tell it to do that.

UPDATE: I am an idiot. DialogResult was set to Cancel on the button as I'd copy+pasted it from the existing Close button and not realised that property was set
Is it possible to resize my controls on my form when I run it? The problem I have is that I have created a windows application which has a maximize state on all forms but on some machines my controls go missing (mostly on widescreen laptops). Ideally some way of resizing my controls would probably be best? So is that possible?
View 10 RepliesI've run in to a very annoying situation. At the moment I have a program with 4 forms. 3 of these forms work fine, but the fourth seems to be a dud. After clicking any one of the buttons or controls on this form it works. But if I try to click anything again, it doesn't work. I can't use my back buttons, I can't even use the minimize, maximize and exit buttons in the top right corner which are automatically built in to the program. I fear I have accidentally changed a setting, or accidentally deleted some very crucial code for this
View 8 RepliesWhat I am trying to do is have a Form which can dynamically change the controls which are on it and their properties; this allows my main GUI to be more fluid and not have tons of groups and controls on it which I must hide and show when needed. To make this as extensible and reusable as possible, however, I want all the control additions/subtractions/edits to occur through a separate DLL which I write. The problem is, I can't seem to instantiate any controls in the Class Library because I cannot import 'System.Windows' or any of its children ('Forms').
View 9 RepliesI did a quick net search and found this which works great for looping through all the buttons to disable them. These buttons are located right on the form.
For Each ctlControl In Form_BLAH.Controls
Select Case TypeName(ctlControl)
Case "Button"
ctlControl.Enabled = False
End Select
Next ctlControl
However...when I tried it on a form where the buttons are contained within a Table Layout Panel it does not work.
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?

View 1 RepliesI'm trying to make an autoupdater, so I've made it search for updates in the beginning and that works fine. But now when the update form is supposed to open, it goes a while and then it says "File Download Complete". So that means the form must have been executed, but it does just not appear. But when I click ok on the dialog, the updater form appears, but with all controls white. Here's my updater.vb: [URL]
I'm using Kleinma's WebFileDownloader class.
I suspect that the problem might be that the updater's form doesn't get it's events handled or doesn't get redrawn.

View 6 RepliesI have a log in form, and once you log in, it's supposed to show a new form.
The problem here is...if I use Me.Close(), then both of the forms close, and the application terminates.
If I use Me.Hide(), than the first form doesn't actually stop running in the memory, and proceeds to run in the background even after you're done with the program.
I am learning VB.NET and as a first task I am creating a login form. I've been trying to link it to another form once a correct username and password are entered. However, despite that I still cant be able to hide it or unload it once the next form is loaded.
Here is the Code
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
If UsernameTextBox.Text = "chris" And PasswordTextBox.Text = "chrispass" Then
Me.Hide()
Form2.Show()
End If
Me.Close()
End Sub
The Form2 appears as coded above but the 'Me.Hide()' manages to hide the login form but then it appears again.

View 2 RepliesI have a small app with one form (form1) which is supposed to be hidden until a hot key combo is pressed. I have read and taken sample code from: [URL]. I do have a keyboard class that hooks keyboard input, (I have my reasons) but it's odd that it will recognise the first hotkey and fire the event, but none after that? The problem is, I can make the form show, but not hide again. It will only recognise one shortcut, one time. How do I make it respond to another hotkey combo? Is the handle changing? Even with focus, the enabled form is not hiding again.
