I have wpf application in which I am using "ENTER" key as "TAB & Enter". If data are valid then move to next control.
My problem is that I want to raise TAB event programmatically. Please provide some code.....
You don't need to send a TAB key event to the application. Instead, use the MoveNext method to move focus to the next control

While pressing tab key the focus is getting moved through the tab control and the button but not going into the tabpages (tabPage1 and tabPage3)
Considering the fact that you can move between tabpages using arrow keys, Tab key is probably not intended to be used for this, but if you really want to get it to work this way then you should add a KeyDown event
if (e.KeyCode = Keys.Tab)
{
//logic which changes TabControl.SelectedIndex. If SelectedIndex equals max then select the next control
}
I want to set focus on a button while caret is present in textbox and user can still enter data to textbox. But when user presses enter key, button press will be simulated.
I am currently using a work around to solve this problem by handling onKeyDown event and checking for enter key. But problem is there is no clue for user to understand this as there is not blue border around the button that indicates focus on button.
Here is a example of what I want to implement (user can enter text in textbox while focus is on :
I have tried to search on google and StackOverflow but could not find any relevant result.
This is a fundamental Windows principle. It's not possible to have 2 controls (windows) focused at the same time.
So the focus should be inside the text box. But you can get the visual indication needed by setting the ok button as AcceptButton of the form (you might also want to set cancel button as CancelButton).
In the form constructor, load event or using designer:
this.AcceptButton = okButton;
There is no need to handle KeyDown event - as soon as the text box is not multiline, pressing Enter while the focus is inside it will generate ok button click. The same applies for the button set as CancelButton when you press ESC.
Hi I am having a wpf application. I need to show some hot keys to user when they press alt key. The hotkeys must be displayed untill any keydown or click happens. this is similar to XamRibbon alt key I guess this is the same functionality in Excel using alt key.
I could implement by using InputBindings and KeyDown and KeyUp events but my business need is to let it display till user clicks somewhere else or some selection happens or some typing happens. which is the same in XamRibbon and Excel.
How do we achieve this kind of behavior??
I have a problem regarding combobox dropdown. Once a dropdown is opened, if I want to move focus to other control (say a textbox), I need to click twice because on first click, the combo dropdown is closed and then on second click, the textbox gets focus. How should I fix this? Please help.
You could listen to the DropDownList.SelectedIndexChanged event, and in the event handler set focus to the next control, either by setting TextBox.Focus(), or by calling System.Windows.Forms.Control.SelectNextControl()
I think this would be 'non standard' behaviour for what its worth. Its quite normal to expect the user to tab or select the next control after using a drop down.
Edit: Sorry, in a WPF ComboBox the equivalent event is SelectionChanged, but on reflection you'd be better using OnDropDownClosed. This would mean you only move the focus specifically after using the drop down rather than just whenever the value changes.
For a certain inputform, I'd like to make it possible to do input with the keyboard. I know how to read the keys through KeyPressed and KeyUp, but the problem is that when a control has got the focus and the user presses the Enter key, that control receives the a Click event. Is it possible to prevent that behaviour ? Or is it possible to know if a Click Event was fired by the mouse or by the keyboard ?
Does this help? From Microsoft Knowledge Base
Move the Button's code from the button.Click() to a button.MouseClick()
This would be easier if you could describe the situation and exact behaviour you want... :)
You can set:
Form.KeyPreview = True
This sends Key Events to the Form first, and then to the Control. This gives you the opportunity to catch Key Events on the form and 'cancel' them:
e.Handled = True

Also make sure you haven't set the AcceptButton for the Form!
You can also listen for keyboard events and filter out keys.
