I am looking for a way to tell when a tab has taken focus. I tried the gotfocus call but it doesn't seem to get called when I click on the tab. Did a quick search on google but can't seem to find the answer.

I am looking for a way to do something (as in, call a procedure) whenever a textbox gets focus in ASP.NET but I couldn't find my way out. I am using VB.NET.
I have a mdi and 3 child windows.The program start with an empty mdi.With a menu you can open each child window once.When i open for example 2 windows. And close the one on top. The one left(the window under the one i closed) should get focus. How can i manage this?
why i need this?each childwindow has a event gotFocus. Depending on the focus my menu should change.
Private Sub frmMain_gotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.GotFocus
I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]
I just added a gotfocus and lostfocus handler for all of my textboxes. Below is my routines to call on gotfocus/lostfocus.
[Code]...
Now, my issue is that this works great if you use the mouse and click around in the textboxes. However, if you hit the TAB key to move around on the screen, the LostFocus event doesn't seem to work. All of my textboxes backcolor remains lightblue. What did I do wrong? What do I need to do to fix this problem?
In vb.net I would like to set all numericUpDown (NUD) controls to select their value when they receive focus, like a text box does. Do I need to write a GotFocus handler for each NUD? I know I can use widthBox.Select(0, widthBox.ToString().Length) to do the selection I just need to be able to apply this to all NUD GotFocus events.
View 2 RepliesI know that with the Command Button, you can utilize the PerformClick option. I would like to know how you would go about doing something similar for a Combobox.What I am looking to do is open the Combobox within the GotFocus method.
View 2 RepliesI have two web browser controls on my form. I also have several buttons like bold, underline, etc. My probem is the gotfocus of the web control is not working correctly. If I click on the web browser control to add text the gotfocus is not fired. If I click on a text box first and then click in the browser control it is fired. I need to know which has focused so the bold etc know which control to work on.
View 1 RepliesThe problem is that the method is getting called multiple times when the text box control gains focus. I am looking for it to just run once since the method is filling the text box control with data. Is there a common reason this happens? Its not looping cause it is happening on everyone of my controls that use the GotFocus method.
View 7 RepliesI got mainform which has a tab control on it.
on one of the tabs, i have a button that sets:
install.mdiparent to me and then show.
It doesnt show the form.
Its because of the tab control. So i tried to send the tab control to the back, and the install form to the front. that still doesnt work.
Anyway to set the tab page as the parent container?
So using webbrowser, I created a browser. It's tabular and the tabs show the documenttitle of the site. My question is, is it possible to create a picture box in the tab control, to ad the favicon image? Like modern browsers which show the favicon before the document title.
View 3 RepliesI'm just not able to add a custom TabControl to my project. I have found a custom tabControl here: [URL]. The CustomTab consists out of 4 .vb files. Normally I would add a component (.dll or exe) to my project. I tried adding the 4 .vb files but unfortunately no CustomTabControl.
View 3 RepliesI have a form where the user will choose multiple clients from a subform that has a DGV.Each row has a checkbox indicating that it has been selected.When the user is finished selecting the clients, I need to store the selected clients ID Number, Name, and Program Number either in a temp table or another method to only handle about 30 records.After that part is done, I need to create a new tab for each client which has a UserControl on the tab. I have the new tab thing working but I need to learn to apply the client to the first new tab/user control then create another and so on.

I have created a customized tab control (i.e. inserted a 'close' image to the right side of the tabpage, which accepts click envent). Hence, the Drawmode property of the control is set to 'OwnerDrawFixed'. Now I want to insert a icon(likely favicon) to the left side of the tab page. Since the drawmode property is set to 'OwnerDrawFixed', I was unable to use the Imagelist property.

In my form I have a TabControl that has 13 TabPages. I have been able to print the Entire form, but I would like to just print everything in various (not all) TabPages. Each of the TabPages have a several PictureBoxes and several Labels.
Where should I start to simply print the TabPage?
I ahve this code to drag and drop a tab, but my controls don't move with it.When it's moved, the tabpage is empty.How can I fix this?
[Code]...
It's quite strange... The text headers of the tabcontrol's tabpages are gone... Even when I set them again, they are not disappear, design-time nor run-time.
View 2 Repliesdetermine if a tabpage of a tabcontrol is being hovered over.I wanna set a property to true if it is hovered over and if it is I will then highlight it.this is what I have
vb.net
Private _MouseHover As Boolean
Public Property IsMouseHovered() As Boolean
Get
[code]....
this clearly will put it over any tab page I need to make the property specific for each tab page.
I am currently working on an OOP assignment based on vehicles as classes. The classes, attributes and object lists have been completed so far. In my main menu form, I have a tabControl from which each page displays is related to each class. Within each page, labels are included displaying attributes of the first related object in the list. There are also two buttons in each page for scrolling between each listed object from the same class. I want these forward/back buttons to be able to retrieve attributes from the next object in the object list and have them displayed in their relevant labels.
View 3 RepliesHow can I change the color of the tabs of a tabcontrol? I tried to search the forum but everytime I hit the search button I get an "Bad Gateway" error.
View 2 RepliesI have a created a program that allows the user to select an option button and that button takes them to the correct tab. Ive set all the tabs to visable = false untill the option button has been selected. The problem i am having is setting the focus, so the button sgoes to the tab instead of just making it visable again.
View 2 RepliesI have one form with one tabControl with two tabs, in each one I have one dgv, in the visible change event I create and add a new button column, that will be placed at the end. Now the "problem", if the first tab it's selected when the form becomes visible, the column it's placed in the correct position (last), and in the second tab the column it's placed in the third position.
If I do this with the second tab selected when the form become visible, the column it's placed correctly in this one, and in the third position in the first one... The code that I use, it's very simple, every datagrid it's bounded to a datatable, I tried the add method, then I tried the insert method, then I manually set the display index for each column, and none of this options solved my problem...
I would like to add a custom context menu to my web browser. My web browser runs through tab control so it is different then adding a contextmenustrip which i have tried.
View 6 RepliesI am back with new problem using TabControl in VBNET2008 Window Application I am trying to figure out how to determine logically either TabPage1 or TabPage2 header button is clicked on.
The TabControl has 2 Pages:
TabPage1 Text = Display Orders
TabPage2 Text = Edit Transaction.
I need to know which one is clicked on in order to write the routines.
I'm using a TabCotrol in my project , and I want to load as many tabs pages as I need with a PDF control within each tab page so I used this code :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim NewAdobePage As New AxAcroPDFLib.AxAcroPDF
Dim tb As New TabPage
[CODE]...
And now I want to use OpenFileDialog control to load PDF files into any of the already opened AxAcroPDF controls , How ?
I'm trying to make an MDI TabControl Container usercontrol, which is used instead of the MdiClient control in an MDI application. Instead of MDI Forms, you can use (modified) TabControls that behave like (maximized) MDI Forms in a Tabbed environment.
A great example is of course the Visual Studio IDE. Each window is just a TabPage on a TabControl (at least it looks like it is, I don't know exactly how it works in the IDE.. but let's assume it is).Now, the VS IDE uses some great functionality which I believe is called TabGroups. By Right-clicking (or dragging it into nothingness) a TabPage 'header', you can choose New Horizontal / Vertical Tab Group, which splits the 'container' into two TabControls, each with their own TabPages, with a splitter in between so you can resize them.
I have been trying to recreate this behaviour, and I must say it works pretty well so far for very little effort. The only (major) downside is, it only works for Vertical OR Horizontal TabGroups. I have no idea how I can possibly make it work using both vertical and horizontal TabGroups simultaneously...
What I did is pretty simple: I have a mdiTabControlContainer which is just a blank UserControl. I made a public property TabControls that returns a (custom) mdiTabControlCollection (inheriting from a generic Collection(Of mdiTabControl) which is basically just a collection of my tabcontrols.
When the collection is modified, I call a RedrawTabControls method which first clears the Controls (deletes all TabControls), and then adds them one by one. First the last in the collection (docked Fill) then the rest docked Left. I also add a splitter between each TabControl. (Code at the bottom)If I dock the TabControls to "Top" for example, I can make it Horizontal. But I have no idea how I can possibly dock a few of them to Left and the other few to Top...? I would need some kind of property that determines which TabControl should be docked where, right? But how and when would I set that property?
The code I'm using now is:
vb.net
Imports System.Collections.ObjectModel
Public Class mdiTabControlContainer
Public Sub New()
[code]....
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?)
I'm trying to create an owner drawn TabControl that looks like the tabs in Visual Studio on XP (might look different in Vista, not so sure).So far, I've got the background and the blueish border, and now I've run into some trouble drawing the 'tab headers' (where the text is displayed).Here's what I got so far:
vb.net
Imports System.Drawing.Drawing2D
Public Class cTabControl
#Region " Colors "
[code]....
Why isn't this working? How do I draw a border like this around a 'normal' OwnerDrawn tabcontrol, without the funky SetStyle method..?also, the DoubleBuffer ControlStyle (in the SetStyles method) option is not listed in the Intellisense list, but it is accepted when I finish typing it... Is that a bug?
I would like to somehow override the "GotFocus" and "LosFocus" event of the textbox.
Here's the deal. I have big registration form with +- 200 TextBoxes and I want the one that has focus to be highlighter [e.g. let's say change the background color to yellow]. I know, I could write the same code for 200 TextBoxes, but that would be time-killing and I'm really not in favour writing the same thing 200 times as well as with such a huge amount of copy-paste I'm almost sure I would make mistake somewhere.
I'm working on a web browser with tabbed browsing, however..When a new tab is created, it creates a web browser in it - but I want a function called when the browser is finished loading. I can't create a private sub inside a function, So I am not sure what I should do.
My Code:
Function addtab()
Dim myTabPage As New TabPage()
Dim theweb As New WebBrowser
