如何在标题复选框的检查框上的网格视图中检查所有复选框，包括页面索引

问题描述

我有一个网格视图，其中有一个标题复选框，在该子复选框下面.当我选中标题复选框时，所有复选框均被选中，但仅在gv的现有页面上.当我移至下一页时，我看到未选中下一页的复选框.因此，如果万一我要通过选中电子邮件ID前面的复选框来实现向所有用户发送电子邮件的功能，那么我会遇到一个问题，即只有gv第一页上的用户才能收到电子邮件.它们中的其余部分不能仅仅因为未完全选中复选框而得到它.我在论坛上看到了很多示例，但对我没有用.你能建议点什么吗?这是我的Java脚本代码:

Hi,
I have a grid view in which I have taken a header check box and under that child check boxes. When I check header check box all check boxes get checked but on the existing page of the gv only. When i move to the next page I see that the check boxes of next pages are not checked. So if in case I am making a functionality in which i want to send emails to all users by checking the check boxes in front of there Email Ids i encounter a problem that only users existing on first page of gv receive the Emails. Rest of them don''t get it just because check boxes are not selected completely. I have seen a lot of examples on forums but nothing was useful to me. Can u suggest something ? Here is my Java scrip code :

<pre lang="Javascript">
window.onload = function()
{
   //Get total no. of CheckBoxes in side the GridView.
   TotalChkBx = parseInt();

   //Get total no. of checked CheckBoxes in side the GridView.
   Counter = 0;
}

function HeaderClick(CheckBox)
{
   //Get target base & child control.
   var TargetBaseControl =
       document.getElementById(''<%= this.gvAllClients.ClientID %>'');
   var TargetChildControl = "chkEmail_Single";

   //Get all the control of the type INPUT in the base control.
   var Inputs = TargetBaseControl.getElementsByTagName("input");

   //Checked/Unchecked all the checkBoxes in side the GridView.
   for(var n = 0; n < Inputs.length; ++n)
      if(Inputs[n].type == ''checkbox'' &&
                Inputs[n].id.indexOf(TargetChildControl,0) >= 0)
         Inputs[n].checked = CheckBox.checked;

   //Reset Counter
   Counter = CheckBox.checked ? TotalChkBx : 0;
}

function ChildClick(CheckBox, HCheckBox)
{
   //get target control.
   var HeaderCheckBox = document.getElementById(HCheckBox);

   //Modifiy Counter;
   if(CheckBox.checked && Counter < TotalChkBx)
      Counter++;
   else if(Counter > 0)
      Counter--;

   //Change state of the header CheckBox.
   if(Counter < TotalChkBx)
      HeaderCheckBox.checked = false;
   else if(Counter == TotalChkBx)
      HeaderCheckBox.checked = true;
}

请帮忙！

Help please !

推荐答案

//Check all checkboxes in the grid.
function CheckAll(header,gridView)
{
    id = gridView.id;
    var rowCount = gridView.firstChild.childNodes.length;
    for(var i=2;i<rowCount+1;i++)
    {
        if(i<10)
            controlId = id+"_ctl0"+i;
        else
            controlId = id+"_ctl"+i;
        document.getElementById(controlId+'_chkPost').checked = header.checked;
     }
}

参数标题将是Grid Header列中的CheckBox，而gridView是您的Grid Object.

希望对您有帮助.

The parameters header will be the CheckBox in the Grid Header Column and gridView is your Grid Object.

Hope this helps.
