Is there any way you add usercontrol to a panel at a time...i am using this code..
Dim Project as New Usercontrol
Panel1.Controls.Add(Project)
Panel1.Controls.Add(Project)
And it adds only 1 user control and edited text in that user controls instead of creating a new usercontrol...
I want to add a usercontrol to a panel. My code does not work: Panel1.Controls.Add(uc1)
View 1 Repliesis it add control to a form and add control to a usercontrol is using same method like me.controls.add(newpanel)?im a little bit confuse here because that way is not working. im trying to add a panel, to a usercontrol at runtime. the usercontrol is also added at runtime. for e.g. i have click add bar menu, than a usercontrol appear. then, when the usercontrol is selected and i click on add note menu, it will add a panel that contain labels to the usercontrol. this is what i have done. the 'me' is the usercontrol and i put this code under that usercontrol load event.

I wanted to insert a translation:
I have a UserControl in panel (load at runtime). When I change the size of the window, customize the size of the panel (using "Anchor"). How to adjust UserControl in the Panel?
UserControl.size unavailable from Form
UserControl.size can change only from UserControl?
i have a panel. the autoscroll is set to true. and i have the menu called "add bar". when user click on it, the usercontrol will appear. but different placed. so there will be more that one usercontrol. i want to do the usercontrol y location is increase when the location x is more than 600 for e.g.
If x > 600 Then
y += 200
x = 0
End If
the code above is work, but the problem is, why when i scroll down, and click on "add bar" the value of y location is not same as the previous usercontrol, it should be same on y because it is not yet reach the codition x > 600.
I'm creating a usercontrol with a splitcontainer. I can reposition the split when running, but when designing on a form I can't adjust the position graphically, I can only do it by typing a new SplitterDistance. Is there a way to get a grip on that position at design time?
View 10 RepliesI'm developing a form with usercontrols which have to be edited during disign.The project has a connectionstring in de my.settings.The usercontrol has a property which is also called connectionstring.Now, I want to pass the project connectionstring to the usercontrol connectionstring, when the usercontrol is dragged to a form. (All during design)
View 2 RepliesI have been making a control and have added a property for a list(of CustomClass). The custom class contains a string, an image and a list of another custom class which contains a string and an image. I have added this property to the designer by adding the browsable attributes and all appears to work correctly with this.
My problem comes when running the program. I can set all of the values within the property and I can go back to them and they are saved, however, as soon as I run the program, the values are wiped out as the property is set to Nothing.In order to allow my property to be edited and saved, I realize that I must initialize the list and have done so in the accessor method of the property (if the property's value is nothing).
I have modified the values in the designer and placed a breakpoint on all of the items which use the property and it's underlying field, as well as on the property's methods itself. The first breakpoint hit is of it being accessed and the value is always nothing.
I'm not sure where the values are supposed to be stored as I have checked the designer code where it would normally store types such as strings and I have checked the resources to see if they have been saved there (like an image would be). After running the code, the values in the designer are wiped out also.

I have a TabControl on a UserControl. I want the UserControl to behave like a TabControl as usual (it contains only the TabControl and a Contextmenu), including Design-time behavior.I have spent the last two weeks finding out how to add the Design-time behavior and I think I have come a far way.The problem is with adding TabPages during Design-time (while the UserControl is a custom tabcontrol, it is using regular windows forms TabPages).In the Designer class, I have the following code to add a TabPage:
vb.net
Dim dh As IDesignerHost = DirectCast(GetService(GetType(IDesignerHost)), IDesignerHost) If dh IsNot Nothing Then Dim i As Integer = tc.SelectedIndex Dim name As String = GetNewTabName() Dim tab As TabPage = TryCast(dh.CreateComponent(GetType(TabPage), name), TabPage) tab.Text = name tc.Controls.Add(tab)
[code]....
So it would add the control to the TabPages collection if it was a TabPage, and use the regular routine otherwise.
(I'm now using 'tc.Controls.Add(tab)' again instead of 'tc.tabCtrl.TabPages.Add')
But, I don't think the designer even gets that far because it is telling me I cannot add TabPages to my usercontrol, because only TabControls can accept TabPages... How can I make my usercontrol understand that it is a TabControl (without Inheriting from a TabControl?)
Ok i got a problem when ever i move a panel and a picturebox at the same time. Ok well them bolth move but the panel has a image in it and when ever i move it with the picturebox it creates a balck square behind the picturebox and the panel and how can i see it, well it on the top like picturebox.location(20,20) well balck quare.location(0,0) same size as picturebox how do i fix this cause it messes up the image.

I havn't got any test code for this, as i dont know what way i am going to approach this yet.
at the moment i have a groupbox on a form with 3 radio buttons.
what i would like to happen is when a radio button is selected for it to display a panel with a few controls on it.
i am looking to know what is the best way to code this, i have read a few guides on creating objects at runtime, but none of which i have looked at have any information on adding objects to the likes of a panel.
i am thinking that their are probbably 2 way to attempt this.
my logical thinking tells me i should either
1) Create a class will contain the controls and subs that i need and then try to load the class when it is needed.
2)create a control array then try and work with it that way.
I need to center the red panel in the middle of the dark grey panel, when you resize the form the red panel should be in the middle, and the red panel can't be resize, anyone have a code or property to do this?

I have a few panels that contain the controls, how can I check them all at once rather than use that code above and just change the panel number each time? It'll get pretty messy if I have to keep pasting all that code and just changing one number.

IsLockedName (if IsLocked=True then IsLockedName is a string)

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.

how to move button over a panel from the form in which the button is created dynamically at run-time ?
View 1 RepliesI would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

View 12 RepliesI'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
View 8 RepliesThis is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.
When I do this
Public Class cInherits : Inherits Panel
I get this: Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types.
How do I inherit?
I have a problem with a certain panel in another panel.
I have declared a panel on my mainform that is called panel1 ( dock: fill)
In this panel is another panel ( panelmain )with size 10.000, 10.000 pixels. Now I put the auto scroll property of panel1 to true, so then the panel1 has scrollbars on both sides and can show the whole panelmain.
Now the user has the ability to zoom, which basically means that I just scale Panelmain with all it's child controls.
Like Panelmain.Scale(0.95) ( To zoom out )
And panelmain.scale( 1.05) ( To zoom in)
This works well, but when the user is using the scrollbars in panel1 and after that zooms in ( or out ) the location of panelmain is changing. So I tried to solve this by docking panelmain inside panel1 at the left. But now the vertical scrollbar is gone. how I should dock panalemain inside panel1 to prevent panelmain from moving around but also in a way that both the horizontal as the vertical scrollbar are present?
Im using this code
Private Sub Form1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter
For i As Integer = 38 To 2 Step -1
Panel1.Height = i

I have 2 panels on the form butttt for panel one i want to slide height and panel 2 i want it to slide width.
