updatepanel没有实现局部刷新
RT。aspx局部代码如下
程序代码：<asp:UpdatePanel ID="UpdatePanel1"
runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
<asp:ListItem Text="请跟进" Value="请跟进"></asp:ListItem>
<asp:ListItem Text="请核实" Value="请核实"></asp:ListItem>
<asp:ListItem Text="已报名" Value="已报名"></asp:ListItem>
<asp:ListItem Text="未报名" Value="未报名"></asp:ListItem>
</asp:DropDownList>
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%#Eval("id") %>' />
</ContentTemplate>
</asp:UpdatePanel>.cs DropDownList1_SelectedIndexChanged事件代码如下程序代码：protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
//string value = ((DropDownList)dataListSchool.FindControl("DropDownList1")).SelectedItem.Text;
foreach (DataListItem item in dataListSchool.Items)
{
if ((item.ItemType == ListItemType.Item ) || (item.ItemType == ListItemType.AlternatingItem) || (item.ItemType == ListItemType.SelectedItem))
{
string value = ((DropDownList)item.FindControl("DropDownList1")).SelectedValue;
int id = Convert.ToInt32(((HiddenField)item.FindControl("HiddenField1")).Value);
switch (value)
{
case "请跟进":
DbHelperSQL.ExecuteSql("update person set mark = '请跟进' where id = " + id);
break;
case "请核实":
DbHelperSQL.ExecuteSql("update person set mark = '请核实' where id = " + id);
break;
case "未报名":
DbHelperSQL.ExecuteSql("update person set mark = '未报名' where id = " + id);
break;
case "已报名":
DbHelperSQL.ExecuteSql("update person set mark = '已报名' where id = " + id);
break;
default:
break;
}
}
}
}
