Using WinForms; Is there a better way to find the checked RadioButton for a group? It seems to me that the code below should not be necessary.

When you check a different RadioButton then it knows which one to uncheck… so it should know which is checked. How do I pull that information without doing a lot of if statements or a switch.

Note that this requires that all of the radio buttons be directly in the same container eg, Panel or Formand that there is only one group in the container. You can wire the CheckedEvents of all the buttons against one handler.

There you can easily get the correct Checkbox.

Radio Button in C#

The OP wanted to get the checked RadioButton BY GROUP. While SLaks' answer is excellent, it doesn't really answer the OP's main question. To improve on SLaks' answer, just take the LINQ one step further.

Here's an example from my own working code. Per normal WPF, my RadioButtons are contained in a grid named "myGrid" with a bunch of other types of controls. I have two different RadioButton groups in the Grid.

If your code has the possibility of no RadioButtons being checked, then use "SingleOrDefault. You can use the CheckedChanged event for all your RadioButtons. Sender will be the unchecked and checked RadioButtons.

You can use an Extension method to iterate the RadioButton's Parent. This allows you to query other RadioButtons in the same scope. Using two extension methods, you can use the first determine whether any RadioButtons in the group are selected, then use the second to get the selection.

The RadioButton Tag field can be used to hold an Enum to identify each RadioButton in the group:. In addition to the CheckedChangedEvent wiring one could use the Controls "Tag" property to distinguish between the radio buttons If you want to get the index of the selected radio button inside a control you can use this method:. The code isn't that well tested, but it seems the index order is from left to right and from top to bottom, as when reading a text.

If no radio button is found, the radio button selected event c# returns It turned out my first attempt didn't work if there's no radio button inside the control. I added a try and catch forex at eye level pdf to fix that, and the method now seems to work.

Sometimes in situations like this I miss my youth, when Access was my poison of choice, and I could give each radio button in a group its own value. My hack in C is to use the tag to set the value, and when I make a selection from the group, I read the value of the tag of the selected radiobutton. In this example, directionGroup is the group in which I have four five radio buttons with "None" how to get money fast in rappelz "NE", "SE", "NW" and "SW" as the tags on the other four radiobuttons.

I proactively used a button to capture the value of the checked button, because because assigning one event handler to all of the buttons' CHeckCHanged event causes EACH button to fire, because changing one changes them all. So the value of sender is always the first RadioButton in the group. Instead, I use this method when I need to find out which one is selected, with the values I want to retrieve in the Tag property of each RadioButton.

Stack Overflow works best with JavaScript enabled. The underlying code does not know which one to uncheck, it just iterates all the RadioButton controls below the same parent of the changed control and unchecks the one previously checked.
