I have 3 radio buttons on my WinForm.
I would like to give the user the option to navigate between them also by keyboard.
Is there a way to enable it?
I understand I have to use this code:
if (e.KeyChar==Convert.ToChar(Keys.Down))
But how do I know which single radio button I have to set as checked?
The simplest solution is to use keyboard shortcuts. This entails prefixing one character in each RadioButton's text with the & character.
For example if the text of your radio button is "&Big option" then the user can select this option by pressing the [ALT] and B keys at the same time.
Additionally, once one of the radio buttons has the focus you can navigate between them by using the up and down arrows. In general, the user can navigate between controls by using the [Tab] key. In VS 2010 the tab order may be modified by selecting the View->Tab Order menu item.
The same keyboard shortcut trick works for many other controls. For example if you have a TextBox control preceded by a label control you can prefix a letter in the Label control with &. Now since the Label (by default) can't take the focus, when the user uses the Label's keyboard shortcut, the focus will move to the next control in the Tab Order i.e. the TextBox.
If you want a control to be skipped when using the [Tab] key set its TabStop property to False.

I am writing a WPF application where we are supposed to shift focus from one button to another by pressing the TAB key.
All is fine, but for a specific page, there is a textbox which is always focused so that the user can type in it immediately. But now, when I press TAB, the focus is shifted to the button (which is as per requirement) but as the focus is lost from the textbox, I cannot type anymore.
I want to have a behavior where I can keep the Keyboard focus on textbox but should be able to control the buttons using TAB key as well. In a way, I need to have focus on textbox and the buttons at the same time. Is this possible?
Tried the FocusManager.IsFocusScope = "true", but this did not help.
How can I add a shortcut to a certain button in windows forms application?
For an instance I want to assign the combination CTRL+R to my exit button, so when I press it, the code in that particular button executes.
Write an ampersand ("&") in the Text property of the button before a character to have Alt+that key as the shortcut.
E.g.:
myButton.Text = "Press &me";
would make Alt+M the shortcut.
Beware of duplicates and ensure you only assign a shortcut once per form. You can also assign shortcuts to e.g. Label control to make the control next to the label (in the tab order) get the focus, e.g. a text box control.
If you want to have Ctrl instead of Alt take a look at this SO question, as Plue commented. Be aware that Alt+some key is the usual way, so better have a good reason to change the default behavior.
I have a windows form in C# project that keeps Student Info. I caught the image:
I want to add data with sequential order as follows but when I enter data to Surname textbox, TAB button jumps to E-Mail textbox, then Phone Number textbox and lastly to Date of Birth DateTimePicker.
I made all control's TabStop property "False" on the form except these textboxes. And I arranged their TabOrder via Properties Section as follows 0,1,2.. as I intented. But the order followed as I wrote above. Then I opened Tab Order function via "View" on menu strip.. I clicked all controls which I wanted to use in order, but no use. The form and Tab button act as before. I caught Tab Order function image below:
What shall I do now?
TabIndex is important for controls which are siblings of the same parent. However, if your TextBox and ComboBox controls are each inside different parents then their parent controls must have the proper TabIndex.
In the Windows Forms Designer you can see which controls are children of which panels by bringing up the Document Outline. Go to View -> Other Windows -> Document Outline.
If each TextBox or ComboBox is directly inside a parent then its TabIndex doesn't matter, it can be 0. It's the parent (and possibly the parent's parent's) TabIndex which needs to be in order.
Now that we have VS 2019. Simply go to form.cs[design], click "View" tab at the top of the page and select "Tab Order". This will allow you to click on the form elements in order of which you want them to be tabbed to. Any items not selected will not be tabbable(I think I made this word up). Once complete, click "Tab Order" again to exit view.
I have a WinForm program. In one screen it has several ComboBoxes, TextBoxes, and Buttons. How can I make it so that when the user presses tab, it will go through the fields in sequential order. Meaning from top to bottom? Or we can say "In my defined order"? So, for example, it starts with TextBox1, and then when the user presses Tab, it will go to the next TextBox, and when Tab is pressed again, will go to Button1, etc. etc.
Not sure if it’s possible, but for some reason pressing tab jumps all over the place. What defines the "tab"? what logic does it use to make it jump to the next field?
The TabIndex property of each control defines the tab order within a container (Form, GroupBox, Panel, etc). If you are working in the Visual Studio Designer, you can use the View --> Tab Order menu item to view/edit the tab sequence.
Each control has a property called TabIndex. When a user presses the Tab key, Windows cycles through each control in the order of the tab index. If two controls have the same TabIndex, they are selected in the order in which the controls were added to the Forms Controls collection.
It is also worth noting that if you have a control that can contain a group of controls within it's Controls collection (i.e. GroupBox), the tab processing engine will give tab focus to the parent control and then cycle through all of the internal controls, in their internal sorted order. This means that all child TabIndex values can be maintained independently of all other controls that are in the same collection as the parent control.
You need to use the TabIndex propert on the control. Be aware that according to the documentation, you must set the TabStop property to true in order for it to be included in the tab ordering.
You need to define the TabIndex of each control. There is a button in the designer toolbar to make it easier (I don't remember the name, but you should find it easily... it's probably something like "Tab Order"). Click this button, then click each control on the form in turn.
Each control has a property called "TabIndex". These will by default just be incrementing as you create items. You can set these manually.

I have a control with several textbox controls on it.
Now, when I press tab after I edit one of the textboxes, the focus is switched to the next textbox BUT I need to press an additional tab in order for it to enter the "editing" stage.
The first tab simply draws a dotted background on the textbox ... and the second one actually puts the cursor position inside the textbox. Is there a way when I press tab, to automatically set the cursor inside the textbox?
Thanks./
Are you sure you don't have any hidden controls or other controls that might be accepting focus before your textbox? Either way, you should be able to update the tabindex value of your controls so they follow a logical sequence when tab is pressed.
