View 4 Replieshow to add a click event to the tabpages of a tabcontrol? I tried double clicking it but nothing happened. I tried putting a button on the tabpage but that did not work either.
View 3 RepliesI have a tabcontrol with 3 tabs. I can't see where any event is raised when I click the small tab area (where the name of the tabpage is). I see where an event is raised when I click on the tabpage itself. What is the event for the small tab area? I am getting by with a mousemove event over the currently selected tabpage.
View 3 RepliesI am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?
View 1 RepliesIs it possible to assign the MouseDown event handler or equivalent to an image (from ImageList) of a tabcontrol without using OwnerDraw? I can add images to tabs through ImageList. And I can draw something that looks like a close button on each tab, using OwnerDraw. But I notice that the tab sizes will be fixed regardless of the tab labels. I want the tab sizes to be flexible with the labels. For now, the second best alternative to assign events to tabs seems to be use of contextual menus. But it's true that some people just don't want to right-button-click on tabs.And I have seen a project where somebody uses a 32-bit library declare. And I can't use it because I only develop 64-bit apps.
View 13 RepliesHow do I make a certain tab inside TabControl to be active at form event?
For example, I want TabControl2 to be shown at form load.
TabControl2.focus isn't working.
When I click the left or right arrow buttons on the keyboard my tabcontrol tabpage changes from one tab to another. How can I cancel the arrow buttons from changing the tab pages? In other words how can I disable the arrow buttons when the tabpage has focus? Is it possible to do this without extending the base class?
View 5 RepliesThe only way I found to set the focus on a TextBox inside a TabPage is:
Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
TextBox1.Focus()
End Sub
I'm using a TabControl and have overridden the DrawItem event to produce my own background and foreground colors for the header text. It looks good but there's still grey color around each header. I thought maybe the Padding property could be set to (0,0) but that seemed to have no effect.
View 2 RepliesI've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).
View 3 RepliesI've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

View 2 RepliesI'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).
I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

View 2 RepliesI have a tab control with several pages. Within a page I have a panel. When I drag and drop a database to the panel the datagrid view is placed on the panel, but the bindingnavigator is placed outside the tabcontrol. Running the application shows only the bindingnavigator, which seems to have blocked the tabcontrol. If I cut and paste the bindingnavigator to the panel, and running the application shows the page with the bindingnavigator at the top and the datagrid below. However, the bindingnavigator no longer allows me to add and save entries to the database. I made sure all the properties were the same before and after i cut and pasted the binding navigator.As a test, I removed the tabcontrol, dragged and dropped the database to the empty form, and everything worked.

1) Add a TabControl.
2) You could change it DockStyle to fill the Form.
3) Add TabPages to the TabControl ( as many as you want ).
4) Add whatever controls to the relevant TabPage .
