DataGrid的模版列中加一个DropDownList,这个DropDownList的数据源如何绑定

Question

OnItemDataBound事件中绑定，用e.Item.FindControl找到DropDownList，再绑

Answer 1

<asp:DropDownList Runat="server" Width="80%" DataSource='<%# GetDetailData()%>' DataTextField="name" DataValueField="id" ID="ddlDepart">
</asp:DropDownList>
Public Function GetDetailData() As DataTable
     Dim StudentDataTable As DataTable
     '获取数据
     Return StudentDataTable
End Function

Answer 2

1,用DataSet绑   
    Dim item As DataGridItem
    Dim drop As DropDownList
        For Each item In DataGrid1.Items
            drop = item.FindControl("DropDownList1")
            drop.DataSource=你的DataSet
            drop.DataTextField=你要绑的字段
            drop.DataBind()
        Next
2,用DataReader循环添加项
用FindControl找到DropDownList后
    DropDownList1.Items.Clear
    While dr.Read
        DropDownList1.Items.Add(dr.Item(1))
    End While
