在repeater中使用dropdownlist的dlPage_SelectedIndexChanged事件实现转页怎么没有击发

protected void dlPage_SelectedIndexChanged(object sender, EventArgs e)
{
dlPage.SelectedItem.Text = PageIndex.ToString();
GetPage(); //分页
}
<asp:HyperLink ID="hlFirst" runat="server" BorderStyle="None">首页</asp:HyperLink>  
<asp:HyperLink ID="hlUpPage" runat="server">上一页</asp:HyperLink>
<asp:HyperLink ID="hlDownPage" runat="server">下一页</asp:HyperLink>
<asp:Label ID="lblSome" runat="server" Text=""></asp:Label>

转到<asp:DropDownList ID="dlPage" runat="server"
onselectedindexchanged="dlPage_SelectedIndexChanged" AutoPostBack="True">
</asp:DropDownList>
public static void GetPage()
{
//转到第几页代码
dlPage.Items.Clear();
for (int i = 1; i < PageCount + 1; i++)
{
this.dlPage.Items.Add("第" + new ListItem(i.ToString() + "页", i.ToString()));
}
dlPage.SelectedIndex = PageIndex;
}
protected void dlPage_SelectedIndexChanged(object sender, EventArgs e)
{
dlPage.SelectedItem.Text = PageIndex.ToString();
GetPage();
}
点击第二页时他只加载一下页面，没有触发事件

Answer 1

dlPage.Items.Clear();
for (int i = 1; i < PageCount + 1; i++)
{
this.dlPage.Items.Add("第" + new ListItem(i.ToString() + "页", i.ToString()));
}
dlPage.SelectedIndex = PageIndex;
}
protected void dlPage_SelectedIndexChanged(object sender, EventArgs e)
{
dlPage.SelectedItem.Text = PageIndex.ToString();
GetPage();
}

Answer 2

DropDownList设置了AutoPostBack=true吗？

追问

设置了

追答

那你的问题是dlPage_SelectedIndexChanged这个函数没有触发？

追问

GetPage()
{
dlPage.Items.Clear();
for (int i = 1; i < PageCount + 1; i++)
{
this.dlPage.Items.Add( new ListItem(i.ToString() , i.ToString()));
}
dlPage.SelectedIndex = PageIndex;
}
dlPage_SelectedIndexChanged
{
dlPage.SelectedItem.Text = PageIndex.ToString();
