Answer 1

foreach (GridViewRow row in GridView1.Rows)
            {
                CheckBox cb = (CheckBox)row.FindControl("CheckId");
                if (cb.Checked==true)
                {
                }
            }

Answer 2

一般是把选中了的ID写到一个input 控件里面,用','隔开 返回回去

Answer 3

<ItemTemplate>
<asp:CheckBox ID="Select" Runat="server"></asp:CheckBox>
<asp:Label Runat="server" Visible="False" ID="Label1" Text='<%# DataBinder.Eval(Container.DataItem,"XXX_Id") %>'>

</ItemTemplate>cs在某个方法中,一般是按钮激活的一个提交.:
int iCount =this.DataList1.Items.Count;
for(int index =0; index <iCount; index ++)
{
     CheckBox Cb =(CheckBox)this.DataList1.Items[index].FindControl("Select");
     if(Cb.Checked ==true)
     {
Label Label1 =(Label)this.DataList1.Items[index].FindControl("Label1");
int Id =Convert.ToInt32(Label1.Text);
         //这不取到Id了吗?
         ....
     }
}
