下拉列表和SelectedIndexChanged [英] Dropdownlists and SelectedIndexChanged

问题描述

在下拉列表和SelectedIndexChanged中激活oldposts（）时遇到一点麻烦。



这是我的代码：

 <   asp：DropDownList     ID   =  DropDownList1    runat   =  server    AutoPostBack   =  True    OnSelectedIndexChanged   =  DropDownList1_SelectedIndexChanged > ;  

 受保护的  Sub  DropDownList1_SelectedIndexChanged（< span class =code-keyword> ByVal  sender 作为 对象， ByVal  e  As  System.EventArgs）句柄 DropDownList1.SelectedIndexChanged 
 oldposts（）
 结束  Sub  

错误代码：

最小下拉：指数超出界限 
解决方案
 
当你的索引大于最高值时会发生这种情况数组的索引，在本例中是下拉列表的值数组。检查你的oldposts（）是否有类似于描述的东西。

Having a little trouble with dropdownlists and SelectedIndexChanged in activating oldposts().



Here is my code:



<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">




Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged
        oldposts()
    End Sub




Error Code:



Min Dropdown: Index was outside the bounds of the array.
解决方案
This happens when your index is greater than the highest index of an array, in this case, the value array of the dropdownlist. Check your oldposts() if there is something similar to what was described.

This[^] may help.
