Forms :: Create Tabs Copy Controls From Base Tab To New One?
Nov 3, 2009
I have a tab (created in the form developer) that contains about a dozen controls. I need to be able to clone this tab w/all controls. I have no problem creating the forms. However, the controls don't copy. This is true whether I create the new tab with a string:
TabPages.Add(MO.Name)Or with a tab object assigned to the base form:
Dim NewTab As New TabPage
NewTab = MyBaseTabPage
TabPages.Add(NewTab)
In either case, my first tab has everything it should have the other tabs have, the other tabs have only the tab name.Basically, I want to be able to clone my base tab into n number of tabs.

i am building a tab control (using VS 2010 and 4.0 framework). on Tab 0, this works as expected:
Me.ddUE_B1.SelectedValue = Me.B1.Text <-- changes the combo box selection to what is in the label.
on the other tabs this does not work. when I do a messagebox to show, say, Me.Ea1.Text on Tab 1, nothing is returned.
Is there an issue with referencing controls on tabs that I am missing? In general, I will need to set combo box's value to what is in the database when the form loads.

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?

Using VB.NET 08 I'm using the following code which loops through a datagridview and makes the buttons found in the list visible
HTML Code:CallByName(Me.Controls("btn_" & list.Rows(J).Cells(1).Value()), "Visible", CallType.Set, True)
This code works fine with no issue with the buttons on on the form. However when I placed the buttons in to a tabcontrol on the same form I get the following error:Object variable or With block variable not set.
Does this error relate to the way CallByName calls the button handler and that its different to they way you could otherwise produce the same result using
HTML Code:
button1.visible=true

I need to be able to programmatically create new tabs on a TabControl, add controls to them, and be able to update the controls in each tab from another function. I already have a function to add tabs to the control, and to add controls to those tabs when they are created, but I'm stuck as to update the controls after they have been created.EDIT: This is what I have to make the tabs and add the controls:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tabpage As New TabPage
tabpage.Text = "(empty)"
[code]....
I can't seem to get back into the account I used to post this question, so I have to post my follow-up to Tim's question in the comments for the previous answer as a new answer.Debug.WriteLine(TabControl1.TabPages.Item(2).Controls.Find("textbox1", True).Count) returns 0. The tab and the controls have been created prior.

I have a form that has many tabs and I have some buttons just bellow the tabs, but if I could move those buttons and place them inside the tab I would save some space bellow and I could extend on the tabs. So is there a way of moving controls from one tab to another depending which one has focus.

I am about dead certain that in VB Express 2008 that I was able to have multiple tabs. And, on each tab I put controls. I could also click on a tab and see the controls only on that tab.I am now in Visual Studio Pro and I cannot for the life of me look at what is on a specific tab. Only the first tab wants to shows its controls.Does anyone know how to enable the environment to allow me to view the controls on different tabs?!

I have a form with a TabControl on it. On the first tab I have a DataGridView and I have a series of controls to represent six separate filters that can be applied to the data in the DataGridView. Each of these filters consists of 1. a ComboBox to display the columns in the DGV so the user can select one to filter on2. a ComboBox to contain the different filter conditions ("Equal to", "Greater Than", etc...)3. a TextBox to allow the user to enter the string to filter againstSo that's what's on the first tab. Tabs 2,3, and 4 are visually identical to tab 1 although they will hold different data and have different capabilities.

Starting to design an application and wondering if its ok to have only one form as the application which could hold up to 15 gridviews separated in tabs etc. with a navbar as navigation on the left. Is this too much or ok? Is it better to have one gridview per form? What is the norm?

I use VB. NET 2008. I'm starting to work with the Tab Control and command will want to know about techniques such as adding tabs at runtime using this control.
To illustrate what I'm saying, just take one checked on your browser or in the VB (Start Page, when we add other forms to our project).

I'm just having a small problem with tabpages. I have a program that have multiple forms (on startup they are all created and hidden, except for the one being viewed by the user). When the user open one particular form, I has a tab control with two pages. I also have a toolbar. when the user click a menu option, I call a method that assigns all my controls to a variable (to be used in an insert statement later).
Here's an example of that Sub:
Public Sub SetValues()
'page 1
DateCreated = Date.Now
DateEdited = Date.Now
DateCompleted = Me.DateTimePicker2.Text
[Code] .....
The problem is, the controls on the second page cant be "seen" (this is confirmed by placing a msgbox in the above sub, which comes up blank) until the user open the second tab, at least just once. Then its ok. I know I can just run a small method to quickly open all tabs, but is there a reason this is happening, and a better way to do this?

Using vb.net 2008 Forms. I have a groupbox consisting of several textbox's and a push button. I put this groupbox in a control collection in order to validate each texbox when the push button is clicked.
The code to do this is as follows:
Private Sub bn_updateadditem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bn_updateadditem.Click
Dim InvalidInput As Boolean = False
Controls.AddRange(New System.Windows.Forms.Control() {Me.GroupBox1})
Dim ctrl As Control
For Each ctrl In Controls
[Code] .....
This worked great. However when I moved this groupbox with all its controls onto a tab, the groupbox contents disappeared from the form after the control collection is created and contents validated (per above code).

I'm trying to enable tabs funtionality in the WebBrowser control. I have a TabControl hosting WebBrowser controls in each tab. And a multiline enables Textbox to enter the sites. It looks something like this[code]...
It adds the WebBrowser control to the TabControl at the SelectedTab position. Since the default selected tab is the first, it only adds it to the first tab therefore executing only that browser.
I want to know how I can select the next tab from the loop as the SelectedTab so that when the loop runs again and again, it would keep adding WeBrowser controls to each tab.

If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

I have a query about dynamically added controls to a form. I have a series of buttons which are created and added at run time. I have a two drop down lists and two buttons which are created at design time. Button 1 creates a series of buttons called "Test 1.x" based upon the selection of the two drop down lists. This works fine and am happy with the logic.However.... Button two should remove all the dynamically created buttons from the form.This does not happen. What does happen is that 50% of the buttons are removed starting with the first one. WHen checking the loop it only enters the loop half the amount of times that there are buttons. Very strange. When the loop is run repeatability it will remove all controls. Why will my logic not remove all the dynamically created controls at once? What is wrong with my logic?
I attach two code snippets and the .net file for your consideration.Button method which creates the dynamically created buttons from the two drop down lists and adds to form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Count As Integer
Dim MaxHours As Integer
[code]....

I have a form called BaseReportForm that handles drawing some stuff to in a panel to create a template for a bunch of reports. The drawing all takes place in the Panel's Paint event and this form will always be inherited. In the inherited forms, I draw the specific details of the report in the inherited form's Panel Paint event. So I am drawing to the same panel from the base form and from the inherited form. It all works fine, but when I try to open the design view for the inherited forms, I get the following error..
Quote:
The event Paint is read-only and cannot be changed.
I'm not sure I am handling my paint events correctly. Is there a different way I should be handling the drawing of these reports?

I've created a Windows Form app in VB however I've decided the format is best suited to a Wizard style app. I've read a bit about creating wizards however I was hoping VS 2010 had a wizard to create wizards :) From what I've read there is a lot of coding to be done to create a simple wizard. Am I wrong ? Perhaps there is a third party app which generates the base wizard code?

I have a base form and I inherit other forms from it. However, if i go back and change say the size of the base form, I don't see those changes take effect in my inherited forms. Does anyone know why that is? Is there a solution to this issue?So as far as design is goes, what exactly gets inherited by other forms?
