How to get value of Radio Buttons in Winforms/WPF?

To get the value of a radio button in Winforms or WPF, you need to first group the radio buttons together using a container control such as a GroupBox or Panel. Then, you can use a loop to iterate through the radio buttons in the container and check which one is currently selected.

Here's an example of how to get the value of a radio button in Winforms:

// Get the selected radio button in a Winforms GroupBox foreach (RadioButton radioButton in groupBox1.Controls.OfType<RadioButton>()) { if (radioButton.Checked) { string value = radioButton.Text; // Do something with the selected value break; } }

In this example, we iterate through the Controls collection of a GroupBox named groupBox1 and check each radio button to see if it is currently selected. When we find the selected radio button, we get its Text property and do something with the selected value.

Here's an example of how to get the value of a radio button in WPF:

// Get the selected radio button in a WPF Panel foreach (RadioButton radioButton in panel1.Children.OfType<RadioButton>()) { if (radioButton.IsChecked == true) { string value = radioButton.Content.ToString(); // Do something with the selected value break; } }

In this example, we iterate through the Children collection of a Panel named panel1 and check each radio button to see if it is currently selected using the IsChecked property. When we find the selected radio button, we get its Content property (which contains the text displayed on the radio button) and do something with the selected value.

Note that in both examples, we use the OfType LINQ extension method to filter the collection to only include radio buttons, and we use a loop to check each radio button until we find the selected one. This allows us to handle cases where there are multiple radio buttons in the container.
