推荐答案

在radioButtonList中写入AutoPostBack ="True"，而不是"SelectedIndexChanged"事件将触发.
如果要查找所选单选按钮的值，请输入

In the radioButtonList write AutoPostBack = "True" than ''SelectedIndexChanged'' event will fire.

If you want to find the value of the selected radio button then write

RadioButtonList1.SelectedValue;

<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True">
        <asp:ListItem>Search1</asp:ListItem>
        <asp:ListItem>Search2</asp:ListItem>
        <asp:ListItem>Search3</asp:ListItem>
    </asp:RadioButtonList>
    <asp:Button ID="Button6" runat="server" style="height: 26px" Text="Button" />

代码将如下所示:

Code will be like this:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
If RadioButtonList1.Text = "Search1" Then
Search1() ''call function for search1
 Else If RadioButtonList1.Text = "Search2" Then
Search2 ''call function for search2
 Else If RadioButtonList1.Text = "Search3" Then
Search3() ''call function for search3
End If
  End Sub

Private Sub Search1()
''search according to the condition
End Sub

Private Sub Search2()
''search according to the condition
End Sub

Private Sub Search3()
''search according to the condition
End Sub

像这样尝试

Try Like This

<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True">
        <asp:ListItem>Naveen</asp:ListItem>
        <asp:ListItem>Kumar</asp:ListItem>
        <asp:ListItem>aaaa</asp:ListItem>
    </asp:RadioButtonList>
    <asp:Button ID="Button6" runat="server" style="height: 26px" Text="Button" />

在CS中:

IN CS:

Protected Sub Button6_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button6.Click
      con = New SqlConnection(ConfigurationManager.ConnectionStrings("con").ConnectionString)
      If con.State = ConnectionState.Closed Then
          con.Open()
      End If

      da = New SqlDataAdapter("select * from sample where name='" + RadioButtonList1.SelectedItem.Text + "'", con)
      ds = New DataSet()
      da.Fill(ds)
      GridView1.DataSource = ds
      GridView1.DataBind()
  End Sub
