页面脚本
<asp:DataGrid id="DataGrid1" runat="server" AutoGenerateColumns="False" Width="267px" CellSpacing="1" CellPadding="0">
<HeaderStyle HorizontalAlign="Center" BackColor="#DDDDD5"></HeaderStyle>
<Columns>
<asp:TemplateColumn HeaderText="选择">
<ItemTemplate>
<asp:CheckBox id="CheckBox1" runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn Visible="False" DataField="carcode" HeaderText="编码"></asp:BoundColumn>

另外别忘记取出它对应的文件名或文件ID,它们可显式或以隐藏字段表示,若为隐藏字段,则也用FindControl来取

Answer 3

for( int i = 0; i < ListDataGrid.Items.Count; i++ )
{
CheckBox chk = ( CheckBox )DataGrid1.Items[i].FindControl("chkFile");
if( chk.Checked )
{
Response.Write( DataGrid1.DataKeys[DataGrid1.Items[i].ItemIndex].ToString() );
}
}

如果你只需要文件名的话 DataGrid加上DataKeyField="Name"文件名DataGrid1.DataKeys(i).ToString()
