Question

C#listBox赋值给textbox

Answer 1

比如：您的TextBox ID为txtName ，ListBox 的ID为lstTeype
<asp:ListBox ID="lstType" runat="server">
<asp:ListItem Text="悔过衙" Value="悔过衙" />
<asp:ListItem Text"思己之过" Value="思己之过" />
<asp:ListItem Text"悔在衙" Value="悔在衙" />
</asp:ListBox>
赋值代码如下：txtName .Text = lstType.SelectedItem.Text;
或
txtName .Text = lstType.SelectedItem.Value;

希望对您有所帮助。
