I have a tab control and am adding and removing tabs in runtime. I would like to two things. 1) Remove the tab that has focus. 2) Not allow a tab to open if another instance of the tab is already added.

View 2 RepliesDoes anyone know if you can remove focus from all controls on a form so a user doesn't inadvertently cause action on a control when it's unintended such as hitting Enter at the same time your app appears causing some action to occur? Do you have to leave focus on at least one control?
View 12 RepliesI am setting my Winforms Button control properties to appear as a hyperlink would on a web page. I've formatted everything fine, except the border in the FlatAppearance object. I have code to act as pseudo-CSS (FormBackColor is a string constant.):
b.FlatStyle = FlatStyle.Flat
b.BackColor = ColorTranslator.FromHtml(FormBackColor)
b.ForeColor = Color.Blue
[code]....
The code removes the border from the flat Button control except on MouseOver, where I add a 1 pixel border. On MouseLeave, I remove the border. This is to show some visual feedback. This works fine when the button does not have the focus. However, if I click on the button, giving the button focus, mousing out and over again now shows a greater than 1 pixel border around the button. I'm imagining it's combining my button's explicit 1 pixel border with the traditional "Winform Button has the focus, so add a border" border around the Button.How can I disable/remove the "Winform Button has the focus, so add a border" border? Or, should I just do a check in ButtonMouseOver to check if the control has the focus, being a condition of adding the border, and just be done with it?
I have a picture box in which I type some letter on capturing keystrokes.The problem is that at Form Load, the focus is on the buttons available on the form. How can I keep the focus on my Picture Box at form load?
View 2 RepliesI have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.
View 8 RepliesI have a list of textboxs that are binded to a database.
When a user starts to type in one of these textboxs I draw a listbox right under that textbox that shows a list of other items in the field that start with the same keys.
IE, the user types in "Ni" and the list box will have "Nick" and "Nicholas" and so on...
That all works great but when I hit tab I want the next textbox to get focus and the listbox to hide.
If I just wait for the textbox to lose focus you can't do anything with the listbox because DOH the textbox just lost focus and the lsitbox hides.
This has led me in a circle of I'll try this and I'll try that for a while now.
I have listbox.tabstop set to false.
I've tried to manually set focus to the next textbox but the problem is that the listbox gets the focus that instant and all the gotfocus lostfocus code for the textbox is ignored.
I can't out right ignore the listbox getting focus.
I'm developing a program in WPF (VB) that relies on keyboard navigation only.In my program, I have a listbox that displays up to 20000 items.What I want is that when the listbox has keyboard focus, and I move to the bottom item that is visible (using ArrowDown), I want the focus to move to the next item outside the listbox. I'm using PgUp and PgDown to scroll the listbox contents, and text search to jump to items.Is there a way to detect if the focused/selected item is the last/first visible item in the listbox?If so, I could just use:
ListBox1.MoveFocus(New TraversalRequest(FocusNavigationDirection.Down))
I have a listbox on a form and when the user selects a value and the listbox loses focus I want to validate the value the user chose. How do I call my function once the listbox loses focus?
I tried using a custom validator but it gives me an object is missing error.

There are 2 non-modal windows displayed- 1]Form1 contains a Listbox with a list of forms 2]Form2 is the form which is selected in that list Form2 consists of a Maskedtextbox T1. In the Leave event of T1, the validation of text is done. If the data is invalid, a suitable Messagebox is displayed and Focus is set back to that Maskedtextbox (T1.Focus()).Now, if I enter any invalid data and click on the Listbox in Form1, the following things happen:
1]T1 Leave event is entered, focus being on the Listbox
2]Invalid data message box is displayed
3]Focus is set to T1(T1.Focus()) of Form2
4]After End of event, T1 Leave event is again entered. And now, Focus has changed back again to the Listbox.
5]Again Messagebox is displayed and T1.Focus() is done
The issue is, after step 3(focus set to T1), the focus is reset to the Listbox in Form1. Hence Leave event is entered twice and messagebox is displayed twice.
How do you accept key presses when the form does not have the focus? Do you need to use a different event?
View 4 RepliesI am working on a form that allows the user to open a plaintext file into a rich text box.The user can search for a word using a textbox and a find button. The word is then highlighted. I cannot figure out how to keep the word highlighted or selected when I type in my replace box or click anywhere else on the form, the word is no longer selected. have a replace button, which will replace any single instance of a word. But my replace all button is supposed to replace all of the words, and count the number of replacements it makes and display that number in a message box
