gridview里面的checkbox怎么绑定数据

Question

我在gridview里面建了模板列checkbox，但是不知道怎么让checkbox绑定上数据

Answer 1

rowdatabound里绑定，
checkbox cb=(checkbox)(e.row.findcontrol("checkboxid"));
cb.checked=...;//数据源对应的值

Answer 2

不是很明白 LZ 的意思
  是不是让checkbox打钩或不打钩啊，根据数据库里的值 比如是1 就打钩
    是这意思吗，
如果是  首先 你肯定为gridview绑定了数据 假如这个字段叫cbx  在RowDataBound事件里写  
 CheckBox Chk = (CheckBox)e.Row.FindControl("cbx")
 

Answer 3

 /// <summary>
    /// 得到用户的选择项
    /// </summary>
    /// <returns>管理员选择用户的编号集合</returns>
    private ArrayList GetSelected()
    {
        ArrayList selectedItems = new ArrayList();
        foreach (GridViewRow row in GridView1.Rows)
        {
            if (((CheckBox)row.FindControl("chkSelected")).Checked)
            {
                selectedItems.Add(row.Cells[1].Text.ToString());
            }
        }
        return selectedItems;
    }
    

Answer 4

 for (int j = 0; j < datagrid1.Items.Count; j++)
                {
                    if (((CheckBox)datagrid1.Items[j].Cells[0].FindControl("chkRow")).Checked == true)
                    {
                        string del = datagrid1.Items[j].Cells[1].Text.Trim();
                        if (del.ToString() != "")
                        {
                            //删除选中的数据
                            bl.DeleteBasicInfo(Convert.ToInt32(del));
                        }
                    }
                }

Answer 5

用Eval绑定数据源的内容<asp:GridView ID="gvTrade" runat="server" AutoGenerateColumns="false" >
                            <Columns>
                                <asp:TemplateField HeaderText="订单编号">
                                    <ItemTemplate>
                                        <asp:CheckBox  ID="cbNo" runat="server" Text='<%#Eval("id") %>'/>
                                    </ItemTemplate>
                                </asp:TemplateField>                            </Columns>
                        </asp:GridView>

Answer 6

格式有问题，重发一下<asp:GridView ID="gvTrade" runat="server" AutoGenerateColumns="false" GridLines="None" Width="100%">
                            <RowStyle HorizontalAlign="Center" Height="23px" />
                            <HeaderStyle  BackColor="#cccccc" Height="25px"/>
                            <Columns>     
                                <asp:TemplateField HeaderText="订单编号">
                                    <ItemTemplate>
                                        <asp:CheckBox  ID="cbNo" runat="server" Text='<%#Eval("id") %>'/>
                                    </ItemTemplate>
                                </asp:TemplateField>
                            </Columns>
                        </asp:GridView>
