将复选框状态保存到设置文件 [英] save checkbox state to settings file

问题描述

我已经创建了设置文件  3 bool vars scoope用户名为skype_mute和skype_vol_down ....

i already have settings file create with 3 bool vars scoope user named skype_mute and skype_vol_down....

我需要将3个复选框状态保存到设置中提交

and i need to save the 3 checkbox states to the settings file the

我有一个lkistcheckbox有3个复选框，frist是独立的，第二个和第三个是如果2是maked 3rd没有标记，反之亦然如何将值保存到设置文件。

i have a lkistcheckbox with 3 checkboxes and the frist is independent and the second and 3rd is if 2 is maked 3rd is unmarked and vice versa how to save the values to the settings file.

 

之前我使用普通复选框并保存我只需使用：

previously i use normal checkbox and to save i just use:

//in preferences form 3
save button // should save all 3 checkboxes state however this is for normal checkbox and not list checkbox
 private void btn_guardar_pref_Click(object sender, EventArgs e)
        {
            Settings1 set = new Settings1();
            set.cb_MinTarefas = checkBox1.Checked;
            set.Save();
            this.Close();
        }

// check checkbox state before opening form

 public partial class Form3 : Form
    {
        public Form3()
        {
            InitializeComponent();
            Settings1 set = new Settings1();
            checkBox1.Checked = set.cb_MinTarefas ;


// new code to checkbox list 3 checkboxes frist is independent and 2nd and 3rd is just allow select or 3rd or 2nd

  private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
        {
            
                CheckedListBox.CheckedIndexCollection checkedIndices = checkedListBox1.CheckedIndices;
                if (checkedIndices.Contains(0) && checkedIndices.Count == 2 && (int)e.NewValue == 1)
                {
                    checkedListBox1.SetItemChecked((e.Index == 1 ? 2 : 1), false);
                }
                if (!checkedIndices.Contains(0) && checkedIndices.Count > 0 && (int)e.NewValue == 1)
                {
                    checkedListBox1.SetItemChecked((e.Index == 1 ? 2 : 1), false);
                }
              
//in form1 main form
            

         private void Form1_Load(object sender, EventArgs e)
        {

            VerificarActualizaçoesWebradio();

            Settings1 set = new Settings1();
            bool checkedValue = cb_MinTarefas ;

so the checkbox names are 1- cb_MinTarefas 2nd is cb_BaixarVolSkype 3rd is cb_SkypeMute

so how can i do this?

您可以使用数据绑定。
$以下b $ b是两个方法的示例：v1和v2。



 

you can use databinding.
below is an example with two approaches: v1 and v2.

 

using System.Data;
using System.IO;
using System.Windows.Forms;
using System.Xml.Linq;

namespace WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            var xml = @"<root>
                <data checked='true' />
            </root>";

            // v1: load xml and binding to xelement
            var xe = XElement.Parse(xml);
            var cb1 = new CheckBox { Parent = this, Dock = DockStyle.Top, Text = "XElement" };
            cb1.DataBindings.Add("Checked", xe.Element("data").Attribute("checked"), "Value");

            // v2: load xml and binding to dataset
            var ds = new DataSet();
            ds.ReadXml(new StringReader(xml));
            var cb2 = new CheckBox { Parent = this, Dock = DockStyle.Top, Text = "DataSet" };
            cb2.DataBindings.Add("Checked", ds, "data.checked");

            // test
            this.Menu = new MainMenu();
            this.Menu.MenuItems.Add("trace", (s, e) => 
            {
                foreach(Control c in this.Controls)
                    foreach(Binding b in c.DataBindings)
                        b.WriteValue();

                // todo: save to file
                MessageBox.Show("DataSet: " + ds.GetXml() + "\n\n XElement: " + xe);
            });
        }
    }
}
