[英]C# - If A Radiobutton Selected In GroupBox, Unselect Other Radiobuttons In Other GroupBoxes
I have 11 GroupBoxes and 40 RadioButton in my project. 我的项目中有11个GroupBox和40个RadioButton。 I wanna make when I select a RadioButton in a GroupBox, the other RadioButtons in other GroupBoxes unselect. 我想在GroupBox中选择一个RadioButton时,取消选择其他GroupBox中的其他RadioButtons。
You can recursively search the Form for all RadioButtons, then wire them up and use code like suggested in the linked question from the comments. 您可以递归地在“表单”中搜索所有RadioButton,然后将它们连接起来并使用注释中链接问题中建议的代码。
It might look something like: 它可能看起来像:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
FindRadioButtons(this);
}
private List<RadioButton> RadioButtons = new List<RadioButton>();
private void FindRadioButtons(Control curControl)
{
foreach(Control subControl in curControl.Controls)
{
if (subControl is RadioButton)
{
RadioButton rb = (RadioButton)subControl;
rb.CheckedChanged += Rb_CheckedChanged;
RadioButtons.Add(rb);
}
else if(subControl.HasChildren)
{
FindRadioButtons(subControl);
}
}
}
private void Rb_CheckedChanged(object sender, EventArgs e)
{
RadioButton source = (RadioButton)sender;
if (source.Checked)
{
RadioButtons.Where(rb => rb != source).ToList().ForEach(rb => rb.Checked = false);
}
}
}
