在只包含文本项的组合框中获取所选文本的最简单方法是什么?

SelectedValuePath="Content"

<ComboBox 
  Name="cboPickOne"
  SelectedValuePath="Content"
  >
  <ComboBoxItem>This</ComboBoxItem>
  <ComboBoxItem>should be</ComboBoxItem>
  <ComboBoxItem>easier!</ComboBoxItem>
</ComboBox>

.SelectedValue.ToString()

   stringValue = cboPickOne.SelectedValue.ToString()

为了澄清海因茨和吉姆·布里松的答案,这里的代码是 Visual Basic语言

Dim text As String = DirectCast(cboPickOne.SelectedItem, ComboBoxItem).Content.ToString()

和 C级# :

string text = ((ComboBoxItem)cboPickOne.SelectedItem).Content.ToString();

string SelectedItem = MyComboBox.Text;

如果您已经知道ComboBoxItem的内容只会是字符串,只需以字符串形式访问内容:

string text = ((ComboBoxItem)cboPickOne.SelectedItem).Content.ToString();

如果在组合框中添加项

youComboBox.Items.Add("Data"); 

然后用这个:

youComboBox.SelectedItem; 

DataRowView vrow = (DataRowView)youComboBox.SelectedItem;
DataRow row = vrow.Row;
MessageBox.Show(row[1].ToString());

使用 cboPickOne.Text

var s = (string)((ComboBoxItem)cboPickOne.SelectedItem).Content;

Dim s = DirectCast(DirectCast(cboPickOne.SelectedItem, ComboBoxItem).Content, String)

自从我们 知道 ToString() 方法调用。

DataRowView.Row.Item[Index] 或 ItemArray[Index] 属性以获取 SelectedItem ,其中Index是 DataTable 用作 itemSource

VB语言:

Dim sItem As String=DirectCast(cboPickOne.SelectedItem, DataRowView).Row.Item(1).ToString()

String sItem=((DataRowView)cboPickOne.SelectedItem).Row.Item[1].ToString();

VB语言:

Dim sValue As String=cboPickOne.SelectedValue.ToString()

C级#

String sValue=cboPickOne.SelectedValue.ToString();
