在下拉列表中显示selecteditem.value，在文本框中显示checkboxlist [英] display selecteditem.value from dropdownlist and checkboxlist in a textbox

问题描述

在下拉列表中选择MS SQL Server并在CheckboxList中选择Beginner时，我希望它在文本框中显示，然后单击添加按钮，结果应该在文本框MS SQL Server中 - 初学者在我的例子中，代码看起来像这样，它只在文本框中显示Beginner，而不是我在下拉列表中选择的值。

  protected   void  ButtonAddDataBase_Click（ object  sender，EventArgs e）
 {
 
 
  switch （DropDownListDataBase.SelectedItem .Value）
 {
  case    MS SQL Server：
 TextBoxResultDataBaseSkills.Text = DropDownListDataBase.SelectedItem.Value; 
 
  break ; 
 
} 
  switch （CheckBoxListDataBase.SelectedItem.Value）
 {
  case   初学者：
 TextBoxResultDataBaseSkills.Text = CheckBoxListDataBase .SelectedItem.Value; 
  break ; 
} 
 
 
 
 
 
}

解决方案

试试

 listBox.SelectedItem.ToString（）
 

如果在ValueMember中没有指定属性，则SelectedValue返回对象的ToString方法的结果。



编辑：



更改：CheckBoxL istDataBase.SelectedItem.Value

进入 - > CheckBoxListDataBase.SelectedItem.ToString（）;

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.

protected void ButtonAddDataBase_Click(object sender, EventArgs e)
    {


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

                    break;

            }
            switch (CheckBoxListDataBase.SelectedItem.Value)
            {
                case "Beginner":
                    TextBoxResultDataBaseSkills.Text = CheckBoxListDataBase.SelectedItem.Value;
                    break;
            }





    }

解决方案

Try

listBox.SelectedItem.ToString()

If a property isn''t specified in ValueMember then SelectedValue returns the results of the ToString method of the object.

Edit:

Change: CheckBoxListDataBase.SelectedItem.Value
Into -> CheckBoxListDataBase.SelectedItem.ToString();
