使用下拉列表中的选定值 [英] Work with selected value in dropdownlist

问题描述

尝试根据选择的值测试下拉列表.else部分确实有效，因为执行了内部代码，并且我102％确信满足条件，所以我在下拉列表中使用了该名称. ，我需要帮助.

Been trying to test a drop down list according to selected value.The else part does work since the code inside is executed, and I am 102% sure that the condition is met, I have that name in my dropdown.Its confusing,i need help.

<asp:DropDownList ID="ddlStaff"  runat="server" AutoPostBack="true"

                 BackColor="#CCCCCC" ForeColor="Black"  Height="18px" Width="167px"

                    onselectedindexchanged="ddlStaff_SelectedIndexChanged">
             </asp:DropDownList>

以下是下拉菜单中的代码

Below is the code behind the drop down

if (ddlStaff.SelectedIndex.ToString() == "Anele ngqandu")
       {
           MessageBox.Show("ys");
       }
       else
       {
           radDoctors.Checked = true;
       }

推荐答案

您正在使用SelectedIndex，它应该是SelectedItem.Text或SelectedItem.Value(以适用者为准).

You are using SelectedIndex, it should be either SelectedItem.Text or SelectedItem.Value (whichever is applicable).

你好朋友

<pre lang="midl">Lable1.Text = DropDownList1.SelectedValue.ToString();<br />
if( label1.text == "selected value of DDBL")<br />
{<br />
       respose.write("done");<br />
}        <br />
<br />
</pre><br />

尝试使用此代码以获取帮助.

try this code its help u.

您可以使用DropDownList1.SelectedItem.Text或DropDownList1.SelectedValue例如

you may use DropDownList1.SelectedItem.Text or DropDownList1.SelectedValue for example

if (ddlStaff.SelectedItem.Text == "Anele ngqandu")
       {
           MessageBox.Show("ys");
       }
       else
       {
           radDoctors.Checked = true;
       }
