选择Gridview中的所有复选框
我正在尝试选择我在页面上运行的gridview中的所有复选框，我正在使用JQuery和Javascript来实现该功能但javascript似乎不起作用。 我在普通的表上尝试了相同的脚本并且它工作但它似乎不适用于我添加到gridview的复选框。 你能帮助我解决这个问题。 这是页面的代码。

我创建了新项目并使用了您的代码。你的JS不工作的原因是你在服务器控件的Id上转发，例如：
table[id*=tblChck]他们将在客户端浏览器中具有不同的ID。它是ASP.NET如何防止Id重复的。如果您有母版页，则内容页面中的所有服务器控件都会添加一个前缀，例如＆＃34; MainContent _＆＃34;。为了使你的JS工作，你需要将JQ选择器更改为类似<script type="text/javascript">
$(function () {
$("table[id*=tblChck] [id*=chkHeader]").click(function () {
if ($(this).is(":checked")) {
$("table[id*=gvData] [id*=cbSelect2]").attr("checked", "checked");
} else {
$("table[id*=gvData] [id*=cbSelect2]").removeAttr("checked");
}
});
$("table[id*=gvData] [id*=cbSelect2]").click(function () {
if ($("table[id*=gvData] [id*=cbSelect2]").length == $("table[id*=gvData] [id*=cbSelect2]:checked").length) {
$("table[id*=tblChck] [id*=chkHeader]").attr("checked", "checked");
} else {
$("table[id*=tblChck] [id*=chkHeader]").removeAttr("checked");
}
});
});
</script>
的东西，或者你可以添加一个css类并由它选择。
要完全清楚以使代码工作，我必须将JS更改为：
File tempFile = null;
try{
tempFile = File.createTempFile("sign_", "tmp.pdf");
}catch(IOException e){
e.printStackTrace();
} finally {
if (tempFile != null) {
tempFile.deleteOnExit();
tempFile = null;
//Added a call to suggest the Garbage Collector
//To collect the reference and remove
System.gc();
}
}
