将下拉列表中的所选项目放入文本框中

Question

I want to get a selected item from a drop down list, on button click need to show that selected item into a text box.

I haven't tried anything cause i don't know what to do.

Answer 1

Just use this code...

Suppose, Button click event:

   protected void Button1_Click(object sender, EventArgs e)
    {
       Textbox1.Text = DropDownList1.SelectedItem.Text.ToString();
    }

Answer 2

The following class can give you the general idea of doing what you want.

public class MyClass
{
    public MyClass() 
    {
        comboBox = new ComboBox();
        button = new Button();
        textBox = new TextBox();
        button.Click += OnButtonClick;
    }

    private void OnButtonClick(Object sender, EventArgs e)
    {
        textBox.Text = comboBox.SelectedItem.ToString();
    }

    ComboBox comboBox;
    Button button;
    TextBox textBox;
}
