下拉值无法在gridview中刷新 [英] dropdown value not refresh in gridview

问题描述

嗨
我在gridview中使用dropdownlist作为

 <   asp:DropDownList     ID   ="   ="span>   样式  =" 大纲:0"  runat   服务器"  SelectedValue   ='  <％ #Eval (" )％>' > 
<   asp:ListItem    文本  ="  值   0 " <   asp:ListItem    文本  ="  值   1 " <   asp:ListItem    文本  ="  值   2 " 解决方案

Make AutoPostback属性= TRUE 提出建议. lang ="xml"> < asp:DropDownList < big > AutoPostBack ="true " < /big > ID ="drpstatus "Style =" outline:0"runat =" server"SelectedValue ='" 状态值")< asp:ListItem 文本 =" 值 0 " < asp:ListItem 文本 =" 值 1 " < asp:ListItem 文本 =" 值 2 " <asp:DropDownList ID="drpstatus" Style="outline: 0" runat="server" SelectedValue='<%#Eval("status_value")%>'> <asp:ListItem Text="Inactive" Value="0"> <asp:ListItem Text="Active" Value="1"> <asp:ListItem Text="Rejected" Value="2">

when i bind 1st time it show correct selected value but when i change the value through another webform and refresh this page the value still remains same and i checked in database it has changed but not it is not changing in dropdown

please suggest

解决方案

Make AutoPostback Property = TRUE of your dropDownList.

<asp:DropDownList <big>AutoPostBack="true"</big> ID="drpstatus" Style="outline: 0" runat="server" SelectedValue='<%#Eval("status_value")%>'>
<asp:ListItem Text="Inactive" Value="0">
<asp:ListItem Text="Active" Value="1">
<asp:ListItem Text="Rejected" Value="2">

try this,

All the best :-)
