如题:detailsview insert mode 中有两个下拉列表框,如何让他们联动,联动效果有刷新的也没问题.
我现在搞不懂第二个下拉框如何取得第一个下拉的seletedvalue,
------解决方案--------------------------------------------------------
给DropDownList1绑定一个事件SelectedIndexChanged,如下：
- HTML code
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"></asp:DropDownList>
------解决方案--------------------------------------------------------
抓DropDownList1可以这样
- C# code
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { DropDownList ddl1 = (DropDownList)sender; DropDownList ddl = (DropDownList)DetailsView1.FindControl("DropDownList2"); }
