标头复选框不选中所有子项，不选中所有子项 [英] Header checkbox on checking not makin all the child child check boxes checked

问题描述

我遇到了一个非常不寻常的问题.我编写了一个Java脚本，该脚本可以更早地正常工作，如果在网格视图中选择了标题复选框，则所有复选框都已选中，但是比向页面添加其他功能和控件时它停止了工作.我无法猜测为什么会这样.我的JavaScript代码是:-

Hi,

I am suffering from a very unusual problem. I wrote a java script which was working fine earlier making all the check boxes checked if I select the header checkbox in grid view but than when I added other functionality and controls to my page it stopped working. I am unable to guess why is it happening. My code of javascript is :-

function SelectAll(id) {

        var frm = document.forms[0];

        for (i=0;i<frm.elements.length;i++) {

            if (frm.elements[i].type == "checkbox") {

                frm.elements[i].checked = document.getElementById(id).checked;

            }

        }

    }  

和C#代码相同的是:

and c# code for the same is:

if (e.Row.RowType == DataControlRowType.Header)
       {

           ((CheckBox)e.Row.FindControl("chkAll")).Attributes.Add("onclick", "javascript:SelectAll('" + ((CheckBox)e.Row.FindControl("chkAll")).ClientID + "')");
       }
