showed checkbox box with checked values

You can use the event CheckedChanged. As you use many checkboxes, you can write only one method and use it for all checkboxes.

You can use the event CheckedChanged. As you use many checkboxes, you can write only one method and use it for all checkboxes.
I recommand you to use a list of values to stock what you want to show in the textbox then work on it (in my example, I sort the data and concatene them).
public partial class Form1 : Form
{
private List listData;
public Form1()
{
this.listData = new List();
InitializeComponent();
}
private void checkBoxs_CheckedChanged(object sender, EventArgs e)
{
CheckBox theCheckBoxChanged = sender as CheckBox;
// verify the event is from a checkbox
if (theCheckBoxChanged != null)
{
if (theCheckBoxChanged.Checked)
{
// add data
this.listData.Add(theCheckBoxChanged.Text);
}
else
{
// remove data
this.listData.Remove(theCheckBoxChanged.Text);
}
this.UpdateTextBox();
}
}
private void UpdateTextBox()
{
// be carefull, you can't concatenate if there is no data.
if (this.listData.Count > 0)
{
// sort and concatenate
this.textBox1.Text = this.listData
.OrderBy(s => s)
.Aggregate((s1, s2) => s1 + " and " + s2);
}
else
{
this.textBox1.Text = String.Empty;
}
}
}

Don't forget to assign the event CheckedChanged of all checkboxes to checkBoxs_CheckedChanged
