您好b $ b

尝试此代码.. < br $> b $ b





<前lang =cs> 受保护 void dl_checkoutitem_ItemCommand（ object source，DataListCommandEventArgs e）
{
string [] checkboxes = { CheckBox6， CheckBox7， < span class =code-string> CheckBox8， CheckBox9， CheckBox10};
string [] checkedCheckboxIds = checkboxes.Where（k = > （e.Item。 FindControl（k） as CheckBox）.Checked）.ToArray（）;

}

i have an datalist controle inside it i have checkboxes for a single row i have 6 checkboxes and i want to find out the id of checkboxes which is checked on itemcommand event how can i findout
below is my datalist

<asp:DataList ID="dl_checkoutitem" runat="server" Width="100%"

                                    onitemcommand="dl_checkoutitem_ItemCommand" >
                            <ItemTemplate>
                           <asp:Table ID="tbl_dal" runat="server" CssClass="table table-striped table-hover table-bordered">

                            <asp:TableRow>
                            <asp:TableCell Width="3%" > <asp:Label ID="lbl_sn" runat="server"></asp:Label> </asp:TableCell>
                             <asp:TableCell Width="15%" >  <%#Eval("User_name")%>  </asp:TableCell>
                              <asp:TableCell Width="20%" ><asp:Label ID="lbl_quantity" runat="server" Text='<%#Eval("Email")%>'>s</asp:Label>  </asp:TableCell>
                              <asp:TableCell Width="9%" ><asp:Label ID="lbl_price" runat="server" Text='<%#Eval("Contact_no")%>' ></asp:Label>   </asp:TableCell>
                              <asp:TableCell Width="9%" ><asp:CheckBox ID="CheckBox6" runat="server" /></asp:TableCell>
                              <asp:TableCell Width="9%" ><asp:CheckBox ID="CheckBox7" runat="server" /></asp:TableCell>
                              <asp:TableCell Width="9%" ><asp:CheckBox ID="CheckBox8" runat="server" /></asp:TableCell>
                              <asp:TableCell Width="9%" ><asp:CheckBox ID="CheckBox9" runat="server" /></asp:TableCell>
                              <asp:TableCell Width="9%" ><asp:CheckBox ID="CheckBox10" runat="server" /></asp:TableCell>
                              <asp:TableCell Width="8"> <asp:Button ID="btn_save" runat="server" Text="save" CssClass="btn"  CommandName="update" CommandArgument='<%#Eval("id") %>' /></asp:TableCell>
                              </asp:TableRow>
                             </asp:Table>
                            </ItemTemplate>
                          </asp:DataList>

解决方案

Hi
Try this code..

protected void dl_checkoutitem_ItemCommand(object source, DataListCommandEventArgs e)
       {
           string[] checkboxes = { "CheckBox6", "CheckBox7", "CheckBox8", "CheckBox9", "CheckBox10" };
          string[] checkedCheckboxIds = checkboxes.Where(k=> (e.Item.FindControl(k) as CheckBox).Checked).ToArray();

       }
