在单击添加按钮时，我希望文本框应显示????????

问题描述

我在Windows窗体上有4个值的Apple，Oranges，Kiwi和Bread combox.我想基于组合框中选择的值以相同的形式更新文本框中的代码.因此，如果Apple在组合框中被选中，则代码应用程序应显示组合框中的奇异果是否比文本框中的值是奇异，依此类推.

我已将所有数据保留在组合框中，但尚未为此创建任何数据.

1.是否必须为此创建Sql Data，然后必须进行连接?

请朋友，我没有4个项目，我还有30个数据，所以请让我知道我如何在组合框中管理此数据


================================================== ================

在单击添加按钮时，文本框应显示我编写的代码，该代码给我错误

           groupBox1 gb = new GroupBox1();
           int topPosition = 5;
           for (int j = 0; j < Convert.ToInt32(textBox6.Text.ToString()); j++)
           {
               comboBox2 cb = new ComboBox1();
               cb.left = 5;
               cb.top = topPosition;
               topPosition += 30;
               gb.controls.Add(cb);
           }
           frmsalesorderbooking.Control.Add(gb);
           frmsalesorderbooking.show();
       }

推荐答案

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
     {
         textBox1.Text = comboBox1.Text;
     }

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        If ComboBox1.Text = "RED" Then
            TextBox1.Text = "RED SELECTED"
        End If
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ComboBox1.Items.Add("RED")
    End Sub
