This is the data in the combo Box

  (M)
  (F)

I want to select a name in the listbox then when I proceed to select the gender from the comboBox the value I select must be added to the end of the name that is selected

example.

Carol Willis(F)

This is what I have tried:

private void Form1_Load(object sender, EventArgs e) {                                                                                this.namesTableAdapter.Fill(this.namesDataSet.names);
    comboBox1.Items.Add("(M)");
    comboBox1.Items.Add("(F)");
    comboBox1.SelectedIndex = 0;
    listBox1.SelectedIndex = 0;
} 
//The code above loads the items into the comboBox 
//For the lisbox I connected to the database using the option "Use Data Bound Items"

Any form of help will be appreciated

Answer 1

这应该指向正确的方向：

public ListBox lbNames = new ListBox();
public ComboBox cbxGender = new ComboBox();

// combobox selected index changed event
private void cbxGender_SelectedIndex_Changed(object sender, EventArgs e)
{
    // check if there are selected items
    if(lbNames.SelectedItems.Count == 1 && cbxGender.SelectedItem != null)
    {
        // replace previous added gender
        Regex.Replace(lbNames.SelectedItem.ToString(), @".+(\([MF]\))", "");
        // append new gender
        lbNames.Items[lbNames.SelectedIndex] = lbNames.SelectedItem.ToString() + cbxGender.SelectedItem.ToString();
    }
}

没有经过测试，只是一个提示。

Answer 2

listBox1.Items[listBox1.SelectedIndex] = listBox1.Items[listBox1.SelectedIndex] + comboBox1.SelectedItem.ToString();

Answer 3

这样的事情可以解决问题：

private void comboBox_SelectedIndexChanged(object sender, EventArgs e)
    {
        foreach (ListViewItem item in listView.SelectedItems)
        {
            if (comboBox.SelectedItem != null)
                item.Text += " " + comboBox.SelectedItem.ToString();
        }
    }

不要忘记在表单上的ComboBox属性中双击/添加“SelectedIndexChanged”事件。
