Determine If TabPage Active Or Not?
Jul 4, 2011I tried this:
If TabControl1.SelectedTab = TabPage2
But it didn't work.
I tried this:
If TabControl1.SelectedTab = TabPage2
But it didn't work.
i am using a tabcontrol with close button.i have 4 tabpage and i call each tabpage through menustrip.
MainTab.TabPages.Add(TerminalPage)"for tabpage1"
MainTab.TabPages.Add(Attendance)"for tabpage2"
MainTab.TabPages.Add(Multimedia Projector)"for tabpage3"
MainTab.TabPages.Add(Conversation)"for tabpage4"
i can open and close it without any problem. my problem is that how can i determine if the tabpage is already open? bcoz for example if the tabpage1 is already open, clicking MainTab.TabPages.Add(TerminalPage)"for tabpage1" this will add another tabpage named terminal page.
determine 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 building a sort of 'lightweight' Visual Studio, and I'm trying to implement the feature where you can drag tabs to different 'tab groups', viewing multiple tabs side by side.
I got nearly everything working, I show a ContextMenuStrip when you rightclick the tab headers, with the option of creating a new (horizontal or vertical) Tab Group. When that happens, a new TabControl is added dynamically and the selected tab is moved there. You can drag the tabs around inside a TabControl and even from one to another.
The problem now is keeping track of the 'active' tab. Since I have multiple TabControls (not just two, there can be as many as you want theoretically), their SelectedTab properties are basically useless. How am I to determine which TabControl the user is currently working in? Obviously I will always have multiple selected tabs, but only one active tab, in which the user is currently typing, editing, whatever.I need to know the active tab for obvious reasons: many menu and toolbar items act on the active tab for example. A short explanation of my controls:I have one TabGroupContainer control, which inherits UserControl. I have a TabGroup control, which inherits TabControl.I have a Tab control, which inherits TabPage.
The TabGroupContainer holds a collection of TabGroups (to which I dynamically add/remove TabGroups when required). Now I want the TabGroupContainer control to have the ActiveTab property which returns the one and only active tab (out of possibly many selected tabs).The only logical way is to keep track of the tab that was selected last, for every TabGroup.
At the moment, I am doing this:
- In the TabGroup (TabControl) class, I shadow the SelectedTab property (and return a Tab instead of a TabPage). More importantly, in the property setter, I raise a SelectedTabChanged event:
vb.net
Public Shadows Property SelectedTab As Tab
Get
Return DirectCast(MyBase.SelectedTab, Tab)
[code]....
However, it still doesn't work. I soon figured out why: I am checking that the previously SelectedTab is not the same as the new value in the property setter of the (shadowed) SelectedTab property. I don't raise the event when they were the same, and in this case they were the same (as there is only one tab in the TabGroup!).So, I took that check out, and now it seems to work when I click in the text editor.
So one problem remains: the active tab is not changed when you click on the tab header (and not on the text editor). I am clueless as to how I should handle this... I am once again sure there is a simple fix, but I cannot see it. I can click the tab header, and I'm sure behind the hood it responds to this click, but it never raises it SelectedIndexChanged event because the index didn't change but was set to the same value it already had. I cannot override the SelectedIndex property (so I could skip this check and raise the event anyway even if the value didn't change), and the OnSelectedIndexChanged method is not called, so I cannot use that either...
When debugging in VB6 it was easy to find the name of the active form because it was automatically highlighted in the Project Explorer.
How do I find the name of the active form in VS2010?
I am trying to display an usercontrol(has several panels one on top of the other panel) on tabpage. I am using below code to achieve this.
[Code]...
I am using System.Windows.Forms.TabPage to store an entire TabPage for later use in My.Settings. Here is a brief description of the application.
I have a TabControl that has 3 tabs. One for user input, another tab for equipment settings, and then a final tab for Oven settings. On the user input tab, if the user de-selects the checkbox for Oven, the oven tab is saved to My.Settings and hidden.
I can then run the application without oven control. After running, lets say the user would like to re-run, this time with the oven. They go back to the input tab and re-select the Oven checkbox. However, the Oven tab doesn't re-appear. When stepping through the code, the is nothing stored in My.Settings for the oven tab page. Why not?
Also, I can open the application, and check, then uncheck the oven checkbox and the tab is hidden, then returns. I can do this all day. However, after running the tab will not return.
I Try so many times to change TabPage Size and Form Size when I shif from One TabPAge to another, This because every TabPAge consist of defrent volume of control which need to enlarge and reduce the size. But I couldn't make it.

[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

I want to get the active control (control which has the focus or where the cursor is on) each time the cursor moves to another control or each time a control receives a focus.

View 3 RepliesI have a standard Visual Studio 2008 VB.Net WinForm application, running on Vista Business. One of the forms has a timer that passes Me.Handle to FlashWindowEx. This works as intended as long as none of the windows that belong to this application are the Foreground window. If this program is running and another application's window is the Foreground window, then it flashes as intended. If, however, any of this application's windows are the Foreground window, then it doesn't flash.

View 6 RepliesIs It possible to have a "new tab" button on a tabpage, like in IE how theres the little square you click to add a new tab. So normally I use a separate button (like on a toolstrip) to create a new tab, but I want to have a button that floats next to the last tabpage in a tabcontrol that adds tabs. It would be great to have a little button at the end of each tab that you can click to close the tab, like in google chrome (I have an attachment, something as close as possible to that. like this is a normal "tabpage button"(the button where you click to show whatever is in the tab) [Tab Text.... ] and I want something like [Tab Text.... X] where the X is a button that closes the tab.

I have a tab control on first page of which there is a flexgrid. some functions are called which throughout make chages to this flexgrid. now during runtime I create more tabpages with exactly the same Flexgrid (as in I have named it the same as the first one so that I should be able to call the same functions and the same modifications should happen with this flexgrid as well. How should I call the function so that the flexgrid used is the one on my new tabpage. if I just call the function with the code Call functionname(), it modifies the same flexgrid control in the first tabpage and does nothing to the new ones on the newly created tabpages

View 3 RepliesI cannot get the dragdrop event to fire when I drag a file from one tabpage to another tab page in the same tabcontrol. I can drag a file from my application and drop into windows explorer and and then drag from windows explorer into my app. That all works fine. And when I drag from one tabpage up to the top of the control, my program uses the tabcontrols dragover event to swap tabs....works fine also. ...Drag drop event fires...no problems
Say I have a list box with files on one tabpage, a list box with files from a different directory on another tabpage, I want to be able to drag the file over and drop it into the other listbox.I have done lots of testing on the variables in the dragdrop handlers to see if they are recognizing the switch in controls and they are. But the dragdrop event will not fire.
I've gone through various thread, posts, classes and walkthroughs on sites but seem to be coming up short either in my understanding or what is/should be going on.I have a very simple data entry tabcontrol (think like microsoft excel but textboxes, labels and the odd combobox rather than a grid). When I click one tab it creates a new tab and names it according the sequence (no problems so far). Here is the crotch kicker (for me at least). I need the first tabpage layout on all additional tabpage so that data can be entered in each separately and stored with constant "processing" (adding and subtracting ).What would be the best approach to doing such a tabpage duplication?
Currently a User control library inheriting from tabpage seems like a good idea but with the 40 or so controls on it is this actually going to function like the first tabpage (as in the one i have now not the one I'd have if i used the user control instead).Do I take the raft of code the designer creates automatically for the tabpage and its controls and simply add them to the click event? Would this create duplication problems with name or would it be ok as they would be tabpage1.lblName and tabpage2.lblName?
i set this code in my mainform form_load Tabcontrol.Tabapages.clear()when i close all the open tabpage from the tabcontrol. there is still a window left of tabcontrol although its empty. it annoys me because i cannot see my mainform wherein it has a design, i cant see it bcoz of that empty tabpage window from tabcontrol.
