I am having trouble initializing a radio button as checked. What I mean is when I open the form, none of my 2 radio buttons are checked, but they work fine after I check on of them. I tried setting one of them as checked in the Form constructor, but it still appears as unchecked:
public frmPreferences(Capitals capit)
{
InitializeComponent();
radEnglish.Enabled = true;
}

You can check a radio button by default by adding the checked HTML attribute to the <input> element. You can disable a radio button by adding the disabled HTML attribute to both the <label> and the <input> .
To check/uncheck a radio button in React, we use the checked property of the input elements, which is set to true when the radio button is checked otherwise it is set to false .
To set a radio button to checked/unchecked, select the element and set its checked property to true or false , e.g. myRadio. checked = true . When set to true , the radio button becomes checked and all other radio buttons with the same name attribute become unchecked. Here is the HTML for the examples in this article.
radEnglish.Enabled = true
This does not set the CheckBox to a Checked state, it enables the control. You could do this in the designer, or you could use the line
radEnglish.Checked = true;
For WPF it's
radEnglish.IsChecked = true;
