I'm using C# to develop WindowsForms application. I have created a form with some panels. Each panel has a RadioButton. When I click a RadioButton, and then other one, both are checked.
How could I simulate that all the RadioButtons are in the same group, so only one can be checked, and the others are unchecked?
Of course, I can control the checkedChanged event for each RadioButton ... but is there any better solution?
Thanks in advance.
RadioButtons are automatically linked if they are inside the same parent. Since you want them to live in different containers you will have to link them manually.

I am designing a windows form in C# and there is a checkbox called "electronic delivery". Under it is a field for "email address". Now I would like to add the option that the email field is only visible if checkbox is checked.
If checkbox is not checked, I would like to have a different field there.
I know how to handle this on the code side, to make things visible/hidden, but how do I place the fields in the form? Should I place one on top of another? Then I won't be able to access the one below to change it's properties.
Or should I keep only one filed and change it's name inside the code?
You could place your controls in FlowLayoutPanel control. The FlowLayoutPanel control arranges its contents dynamically in a horizontal or vertical flow direction.
You could just place them one on top of the other as you suggested. You said you did not want to do this because it would make selecting the properties of the controls difficult.
You can select a control from the combobox drop down menu on the properties section of Visual Studio.
You should create two Different Panels and Add Objects based on the Requirement. After Put visible and Hide Code in the Check Box Checked Event.
Try Panels it Will Work.
You can Simple Move Panel Along with all you objects which make it super Easy.
I have created a form that shows data and the filter that has checkbox in it
combobox
I have used a Button and a Panel to do this and found that the panel is only shown in the parent's panel not float like the combobox
or panel can't do like this?

You want something that cannot be done with parented components (like panels)
I see some options:
(1) owner draw a combobox to include checkboxes, see Codeprojects https://www.codeproject.com/Articles/31105/A-ComboBox-with-a-CheckedListBox-as-a-Dropdown
or
(2) Create a small floating popup form without system menu and a single pixel border. Inside the form, you could place a CheckListBox docked Fill to allow for filter checkboxes for each item.. you may have a look at this topic Is there a simple way to implement a Checked Combobox in WinForms
(3) Both solutions have drawbacks. Actually it may be better to avoid it, find another way to specify your filter options, redesign your UI.
I am not getting it after quite a research, that how can I implement simple Lostfocus like we use to do in Winforms. In Windows Form Control, we usually have LostFocus which I use when someome press TAB to lose focus or use mouse to select other controls. But it is not the case with WPF. I first use LostFocus, but when i press tab it doesn't fire the event. however when I click using mouse to other control it does get fired properly. So, this doesn't solve my problem.
Second, I try to use LostKeyboardFocus, it does get fired when using TAB key, and on few occassion when I use mouse to select other element, but not when I select menu item from Parent window menu.
Also, I have my control on User Control, that I put in TAB control on parent window. But when I press TAb key it always select the Parent Window Menu instead of TreeView I have in UserControl.
Any suggest is great help. Thanks.
Well, my quest for finding logically reasoning is still not satisfied, but I get the simple thing done simply.
#Daniel, as I said I think the two questions are related, well the answer is indeed related. Maybe you can explain my finding that I am putting as answer here.
I simply set the TabIndex property of my Textbox and other control [TreeView] as 1 and 2, now when I press TAB or select the TreeView item using mouse, i got Lostfocus fired up. and since I have Tab Index set within control, it doesn't select Menu item of parent [it does select it as last now]. So that make Lostfocus the function I should use for my purpose.
Anyone with explanation or better solution is still requested to share it. Thanks.
There is option called checkedListBox1 for check box group item..
Like that any control for radio button. and how to bind my data(data set) in that.
User container to have same functionality as like group name.
container can be group box or Panel
There is no such thing for radio buttons. You may, however, look for third party controls or extend the existing CheckedListBox so that only one item at a time can be checked.
The second solution is a bit ugly, because seeing check boxes the user would expect to be allowed to select more than one option.
Put the radio buttons in their own panel, and they will work together, with only one button in the panel being selectable.
As for data-binding, there are several approaches available, such as creating a form Boolean property for each option, and binding each radio button to its property.
An easier approach would be to use Jay Andrew Allen's RadioPanel, which takes care of binding the radio button options to an enumeration field.
I want to have buttons that kind of act like tabs - they switch between "pages" of the application. How can I achieve this effect? I'm thinking that I could just put the controls in some kind of container and toggle the visible attribute, but is that plausible?
I am using WinForms.
The reason I don't want to use a tab control is because some of the panels already have tab controls in them..I don't want to create a nested tab hell. I just want some kind of spiffy button based navigation.
You could "attach" button functionality to Panels, then use the panels as the "tabs". You could even create a UserControl that inherently ties them together.
However, a TabControl (for Winforms) already exists that does this. http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.aspx
If you're looking for something for ASP.Net 2.0 and above, you could try the following: http://www.codeproject.com/KB/custom-controls/TabControl.aspx
I think the best option is to use this WinForms TabStrip control -- a subclass of ToolStrip where the buttons are drawn as tabs, and you simply treat them as such programmatically by switching which panel is shown in your container as tabs are selected.
