Question

因此，基于radiobuttonlist中选择的内容，我希望select命令可以更改为我的数据源。我面临的问题是，如果我设置默认选择的单选按钮，则查询将适用于该

我的radiobuttonlist，用户（下拉列表都位于更新面板中，单击按钮后未更新

这是我的按钮代码

    If user.Text = "ALL" Then
                    SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE [completed] = 'NO'"
                    SqlDataSource23.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND (([completed] = 'YES') or ([completed] = 'XL')))"
                Else
                    If RadioButtonList1.SelectedIndex = 0 Then
                        SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND ([completed] = @completed))"
                        SqlDataSource23.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND (([completed] = 'YES') or ([completed] = 'XL')))"

                    ElseIf RadioButtonList1.SelectedIndex = 1 Then
                        SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND ([completed] = @completed) and tasktype = 'Air')"
                        SqlDataSource23.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND (([completed] = 'YES') or ([completed] = 'XL')) and tasktype = 'Air')"
                    End If
                End If

   UpdatePanel1.Update()
        UpdatePanel2.Update()

Answer 1

我敢打赌你的radiobuttonlist不在updatepanel中，这就是为什么它没有更新。要更新radiobuttonlist，您需要将其放在updatepanel。

中

您需要指定控件的事件名称：Event="SelectedIndexChanged"

<Triggers>
  <asp:AsyncPostBackTrigger ControlID="ddivision" Event="SelectedIndexChanged" />
</Triggers>

datasource select命令不会随单选按钮列表而改变
