dropdownlist绑定的问题

Question

我想在formview中读取记录
textbox可以这样绑定<asp:TextBox ID="name" Text='<%#Eval("name")%>那dropdownlist该怎么绑定啊

Answer 1

要先把数据绑定给dropdownlist
然后设置它选中的记录
 selectIndex= <%#Convert.ToInt32(Eval("name"))%>

Answer 2

dropdownlist如下：
<asp:DropDownList ID="ddl1" runat="server" TabIndex="3">
    <asp:ListItem>共青团员</asp:ListItem>
    <asp:ListItem>党员</asp:ListItem>
 </asp:DropDownList>怎么在前台根据从数据库读取的值使ddl1显示相应选项啊？

Answer 3

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (((DropDownList)e.Row.FindControl("ddl_dept")) != null)
       //  if (e.Row.RowType == DataControlRowType.DataRow)        {
            DropDownList ddl_dept = (DropDownList)e.Row.FindControl("ddl_dept");
            ddl_dept.DataSource = SQLDAL.GetTable("select * from xt_Department");
            ddl_dept.DataTextField = "DepartmentName";
            ddl_dept.DataValueField = "DepartmentID";
            ddl_dept.DataBind();
            ddl_dept.Items.Insert(0,"");
            ddl_dept.Items[0].Value = "0";
            ddl_dept.SelectedValue = ((HiddenField)e.Row.FindControl("HiddenField1")).Value;        }    }
html:
   <asp:TemplateField HeaderText="">
                        <EditItemTemplate>
                            <asp:DropDownList ID="ddl_dept" runat="server" AutoPostBack="True">
                            </asp:DropDownList>
                            <asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("DepartmentID") %>' />
                           
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="Label2" runat="server" Text='<%# Bind("DepartmentName") %>'></asp:Label>&nbsp;
                        </ItemTemplate>
                    </asp:TemplateField>

Answer 4

在数据加载事件中，给DropDownList绑定数据,差不多就是楼上那样子

Answer 5

我用的formview，不能用RowDataBound,我的 dropdownlist的选定值来自数据库我想实现更加数据库的值，使dropdownlist某一项是被selected通过前台<%Eval%>能实现吗

Answer 6

ddl.SelectedIndex=ddl.Items.IndexOf(ddl.Items.FindByText("党员"));
