从数据列表获取复选框值 [英] Get checkbox value from Datalist

问题描述

这是我的代码:

Here is my code:

<asp:DataList ID="DataList1" runat="server" DataKeyField="iPKImage" DataSourceID="SqlDataSource2"

               RepeatLayout="Flow" RepeatDirection="Horizontal">
               <ItemTemplate>
                   <div class="thumb">
                       <a href='<%# "library_image.aspx?imageid=" & Eval("iPKImage") %>'>
                           <asp:Image ID="imgThumb" ImageUrl='<%# "showthumbnail.aspx?img=" & Eval("iPKImage") %>'

                               CssClass="thumbImage" runat="server" />
                       </a>
                       <asp:HyperLink ID="hlTitle" CssClass="thumbTitle" runat="server" Text='<%#Eval("Image")%>'></asp:HyperLink>
                       <div class="thumbOptions">
                           <table>
                               <tr>
                                   <td>
                                       <a href='<%# "library_image.aspx?imageid=" & Eval("iPKImage") %>'>
                                           <img src="skins/common/icons/ico_img_view.gif" alt="View image details" /></a>
                                   </td>
                                   <td>
                                       <asp:ImageButton ID="btnRequest" ImageUrl="~/skins/common/icons/ico_img_request.gif"

                                           runat="server" CommandName="AddToCart" ToolTip="Add to my image request list" />
                                   </td>
                                   <td>
                                       <asp:ImageButton ID="btnDisseminate" ImageUrl="~/skins/common/icons/ico_img_disseminate.gif"

                                           runat="server" CommandName="AddToCart" ToolTip="Add to my image dissemination list" />
                                   </td>
                                   <td>
                                       <asp:ImageButton ID="btnEdit" ImageUrl="~/skins/common/icons/ico_img_edit.gif" runat="server"

                                           CommandName="EditImage" ToolTip="Edit image" Visible="false" />
                                   </td>
                                   <td>
                                       <asp:ImageButton ID="btnDelete" ImageUrl="~/skins/common/icons/ico_del.gif" runat="server"

                                           CommandName="Delete" ToolTip="Delete image" Visible="false" />
                                   </td>
                                   <td>
                                       <asp:CheckBox  ID="cbDownload" runat="server" />
                                       <asp:HiddenField ID="hdnImageID" Value='<%# Eval("iPKImage") %>' runat="server" />
                                   </td>
                               </tr>
                           </table>
                       </div>
                   </div>
               </ItemTemplate>
           </asp:DataList>

现在，如何找到复选框是否已选中，如果要选中该复选框，请在旁边的隐藏字段"中选择该值?

Now, how can I find if a checkbox is checked, and if it is, select the value in the Hidden Field next to it? Thanks in advance!

推荐答案

解决了自己...抱歉！

Solved myself...sorry!

Dim IDList As New List(Of Int32)
        For Each dl As DataListItem In DataList1.Items
            If (CType(dl.FindControl("cbDownload"), CheckBox).Checked) Then
                IDList.Add(Int32.Parse(CType(dl.FindControl("hdnImageID"), HiddenField).Value))
            End If
        Next

请尝试以下..可能会有所帮助

Dim Dl As String =已检查的数据列表项目:< br/>"
对于每个dli作为DataList1.Items中的DataListItem
昏暗的chk为CheckBox = DirectCast(dli.FindControl("CategoryID")，CheckBox)
如果chk.Checked然后
dl + =(chk.Text +< br/>")
如果结束
下一个
DlLiteral.Text = Dl


请参考此 [

plz try below..it may be helpfull

Dim Dl As String = "Datalist Items Checked:<br />"
For Each dli As DataListItem In DataList1.Items
Dim chk As CheckBox = DirectCast(dli.FindControl("CategoryID"), CheckBox)
If chk.Checked Then
Dl += (chk.Text + "<br />")
End If
Next
DlLiteral.Text = Dl
