在自定义控件中有个DropDownList子控件，请问如何触发该子控件的selectindexchaged事件？

Answer 1

不是跟你说过了吗？？你定一一个事件句并举例吧：
Public Event subDropDownListSelectedIndexChanged As EventHandler
Public Sub SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles subDropDownList.SelectedIndexChanged
        Me.EnsureChildControls()
        RaiseEvent FileDropDownListSelectedIndexChanged(sender, e)
    End Sub

Answer 2

Public Event subDropDownListSelectedIndexChanged As EventHandler
Public Sub SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles subDropDownList.SelectedIndexChanged
        Me.EnsureChildControls()
        RaiseEvent subDropDownListSelectedIndexChanged (sender, e)
    End Sub

Answer 3

直接在页面文件上面写：<asp:dropdownlist id="ddlGroup" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlGroup_SelectedIndexChanged"></asp:dropdownlist>public void ddlGroup_SelectedIndexChanged(object sender, System.EventArgs e)
{
//
}
