asp.net uses full selections in the Repeater control for bulk operation instances

This article describes an example of how asp.net uses full selections in the Repeater control to do batch operations.Share it for your reference.Specific analysis is as follows:

Today, I encountered a fully selected operation in the Repeater control, so I checked it on the Internet and found a better one, so I wrote it down.

Once the interface code is simplified (all operations selected):

<script type="text/javascript">

function SelectAll(parentChk, ChildId, bigControlID) {

var oElements = document.getElementsByTagName("INPUT");

var bIsChecked = parentChk.checked;
for (i = 0; i < oElements.length; i++) {

     if (IsCheckBox(oElements[i]) && IsMatch(oElements[i].id, ChildId, bigControlID)) {

 oElements[i].checked = bIsChecked;

      }

   }

}
function IsMatch(id, ChildId, controlID) {

var sPattern = '^' + controlID + '_+.*' + ChildId + '$';

var oRegExp = new RegExp(sPattern);

if (oRegExp.exec(id))

 return true;

else

 return false;

}
function IsCheckBox(chk) {

       if (chk.type == 'checkbox') return true;

       else return false;

}

</script>

  

<asp:Repeater ID="Repeater_xx" runat="server">

       <HeaderTemplate>

   <table>

         <tr>

        <th> option </th>

        <th> data </th>

         </tr>

       </HeaderTemplate>

       <ItemTemplate>

         <tr>

       <td>

     <asp:CheckBox ID="CheckBox_ID" runat="server" Checked="false" />

       </td>

       <td>

     <asp:Label runat="server" ID="Label_ID" Text='<%#Eval("Label_ID")%>'></asp:Label>

       </td>

   <tr>

      </ItemTemplate>

      <FooterTemplate>

  </table>

      </FooterTemplate>

</asp:Repeater>   
<asp:CheckBox runat="server" ID="CheckBoxCz" Text=" Select All / Deselect " onclick='SelectAll(this,"CheckBox_ID","Repeater_xx")'/>
<input class="anniu" id="input_gs" type="submit" runat="server" onserverclick="Gssubmit_Click" value=" operation " />

Background retrieves data for the current row based on the selected item and then operates on it

public void Gssubmit_Click(object sender, EventArgs e)

{

        for (int i = 0; i < Repeater_xx.Items.Count; i++)

          {

                 // Get Checkboxes 

                 CheckBox cb = (CheckBox)rpt_Paper.Items[i].FindControl("CheckBoxCz");

                 // Determine if selected 

                 if(cb != null && cb.Checked == true)

                 {

                   Label id = (Label)rpt_Paper.Items[i].FindControl("Lable_ID");

                   // Get the row ID

                   int ID= Convert.ToInt32(Id.Text);

                  // Corresponding actions 

                    ......

                 }

          }  

}

I hope that the description in this paper will be helpful to everyone's asp.net program design.
