When selecting "MS SQL Server" in the dropdownlist and also choose "Beginner" in the CheckboxList i want it to be displayed in the Textbox afther clicking the button "Add"
So the result should be in the textbox MS SQL Server - Beginner
In my case the code looks like this and it only displays "Beginner" in the textbox and not also the value i select in the dropdownlist

    
            switch (DropDownListDataBase.SelectedItem.Value)
            {
                case "MS SQL Server":
                    TextBoxResultDataBaseSkills.Text = DropDownListDataBase.SelectedItem.Value;
                    break;
                case "MSSQL":
                    TextBoxResultDataBaseSkills.Text = DropDownListDataBase.SelectedItem.Value;
                    break;
                case "MS Access":
                    TextBoxResultDataBaseSkills.Text = DropDownListDataBase.SelectedItem.Value;
                    break;


            }

            foreach (var x in CheckBoxListDataBase.SelectedItem.Value)
            {
                if (CheckBoxListDataBase.SelectedItem.Value == "Beginner")

                    TextBoxResultDataBaseSkills.Text += x.ToString(CultureInfo.InvariantCulture);
                else
                {

                    if (CheckBoxListDataBase.SelectedItem.Value == "Medium")

                        TextBoxResultDataBaseSkills.Text += x.ToString(CultureInfo.InvariantCulture);
                    else
                    {

                        if (CheckBoxListDataBase.SelectedItem.Value == "Expert")

                            TextBoxResultDataBaseSkills.Text += x.ToString(CultureInfo.InvariantCulture);
                    }
                }
            }
                
        }

// Is there any wrong with this code?
