Answer 1

        for (int i = 0; i < oneList; i++)
        {
            if ((oneList.Items[i].FindControl("chkId") as CheckBox).Checked)
            { 
            
            }
        }

Answer 2

     for (int i = 0; i < rptFriend.Items.Count; i++)
        {
            if ((rptFriend.Items[i].FindControl("chkId") as CheckBox).Checked)
            { 
            
            }
        }

<tr> 
                    <td bgcolor="#F4F4F4" style="height: 25px" colspan="4"> 
                        <asp:Repeater ID="oneList" runat="server" OnItemDataBound="OneList_ItemDataBound">

                                        </HeaderTemplate> 
                                        <ItemTemplate> 
                                            <tr>

                                        <FooterTemplate> 
.......................................... </FooterTemplate> 
                                    </asp:Repeater> 
                                </td> 
                            </ItemTemplate> 
                            <FooterTemplate> 
                                </tr> </table> 
                            </FooterTemplate> 
                        </asp:Repeater> 
                    </td> 
                </tr> 
                <tr> 
                    <td height="30" colspan="4" align="center" bgcolor="#F4F4F4"> 
                        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text=" 保  存 " OnClientClick="return ChkKeys();" /> 
                        &nbsp;&nbsp; &nbsp; <input id="Reset1" type="reset" value=" 重  填 " /> 
                    </td> 
                </tr> 简化一下,是嵌套的Repeater.

Answer 4

foreach (Control ctl in Repeater1.Controls)
        {
            if (ctl is CheckBox)
            {
                (ctl as CheckBox).Checked = true;
            }
        }

Answer 5

foreach (Control c in this.Repeater1.Controls)
{ CheckBox check = (CheckBox)c.FindControl("cbDelete1");
if( check != null )
   {
     check.Checked = true;
   }
}

Answer 6

foreach (Control ctl in Repeater1.Controls) 
        { 
            if (ctl is CheckBox) 
            { 
                (ctl as CheckBox).Checked = true; 
            } 
        }

Answer 7

说实话 foreach (Control ctl in Repeater1.Controls) 
        { 
            if (ctl is CheckBox) 
            { 
                (ctl as CheckBox).Checked = true; 
            } 
        }和foreach (Control c in this.Repeater1.Controls) 
{ CheckBox check = (CheckBox)c.FindControl("cbDelete1"); 
if( check != null ) 
  { 
    check.Checked = true; 
  } 
} 还真是不行,我按照"jack20080808"给的这个for (int i = 0; i < rptFriend.Items.Count; i++)
        {
            if ((rptFriend.Items[i].FindControl("chkId") as CheckBox).Checked)
            { 
            
            }
        }自己改造里一个,绝对没问题了,        for (int i = 0; i < oneList.Items.Count; i++)
        {
            Repeater ListTow = (Repeater)oneList.Items[i].FindControl("towList");            foreach (RepeaterItem item in ListTow.Items)
            {
                CheckBox chkbox1 = (CheckBox)item.FindControl("chkId");
                if (chkbox1.Checked == true)
                    strWhere = strWhere + chkbox1.Text.ToString() + ",";
            }
        }
