tabpage

问题 I'm creating an OpenEdge Progress-4GL application, based on a window, where I like to add a tabpage. In order to do this (as there is no tab page control in the palette), I've tried to add the OCX (ActiveX) control "Microsoft TabStrip Control, version 5.0 (SP2)". However, when I try this I get the following error message: Messagebox title: AB Messagebox content: CtrlFrame Unable to create control. Het licentie bestand voor genoemde ActiveX control is niet gevonden. The last sentence is in

问题 i was writing the following if(this.tabControl1.TabPages.Count != ImagesList.Count()) { foreach (var item in this.tabControl1.TabPages) { } } and i couldn't access the controls inside each item using item. But with a defining it's type like if(this.tabControl1.TabPages.Count != ImagesList.Count()) { foreach (TabPage item in this.tabControl1.TabPages) { } } i could easily access them using item.Controls so i was wondering why do i really need to define/cast those items as TabPage , shouldn't

问题 How can I make a transparent tabPage? I found solutions like set both Form's BackColor and TransparencyKey to a color like Color.LimeGreen or override OnPaintBackground with a empty method but TabPage doesn't have neither TransparencyKey property nor OnPaintBackground` method. How can I do that? 回答1: TabControl is a native Windows component, it always draws the tab pages opaque with no built-in support for transparency. Solving this requires a little helping of out-of-the-box thinking, a tab

问题 I thought C# was hard. Try posting a question in stackoverflow. I have a listbox and a button in a usercontrol, itself in a tabpage of a tabcontrol, itself on a form. I need to populate the listbox from the form when the button is clicked. form > tabcontrol > tabpage > usercontrol > listbox & button So, how do you notify the form that a deeply buried button has been clicked and then fill the listbox from the form (or call the usercontrol from the form to populate the listbox)? Thank you guys.

问题 I currently have a Form with a TabControl containing some TabPage s. Each TabPage has several controls with validation logic and appropriate ErrorProvider s. On my OK_Button_Clicked event, I call Form.ValidateChildren() in order to determine whether to save and close the form . Now, suppose I have a control in tab 1 that fails validation, but the currently visible tab is tab 2. When the user presses OK, he would get no visual indication as to why the form is not closing. I would like to be

问题 Is it possible to reorder the tabs in the WinForms TabControl at run-time like IE or Firefox? Links like this don't give me much hope. 回答1: Sure, it's possible! You're most likely trying to overcomplicate the solution. Essentially, all you have to do is subclass the standard TabControl and add some logic to the mouse event handlers. You'll just need to check which form the user is currently dragging and reorder it in the TabPages collection. There are a couple of complete solutions available

问题 I have a complex Windows Forms GUI program that has a lot of automated control generation and manipulation. One thing that I need to be able to do is add a custom UserControl to a newly instatiated TabPage. However, when my code does this I get automatic resizing events that cause the formatting to get ugly. Without detailing all of the different Containers that could possibly be involved, the basic issue is this: At a certain point in the code I create a new tab page: TabPage tempTabPage =

问题 I have used this TabControl to create the following tablayout in a winform application How do i make the tabs appear right to left? I mean make it like this image I also tried to Use RightToLeftLayout property but this tab control doesn't have that property 回答1: It seems that MTC while affected by RightToLeft doesn't draw as expected (In part due to the fact that it statically draws the tabs from left to right and calculates width from the left): It's easy enough to do in WinForms: The secret
