当我运行一个应用程序时,它会显示一个表列表但是当我点击任何一个表时它会抛出一个异常:
只有LINQ to Entities中的排序输入才支持'Skip'方法.必须在方法'Skip'之前调用'OrderBy'方法.
但我没有在我的申请中声明任何查询.
我点击一个标题复选框就有一个GridView.我想检查ItemTemplate中的所有CheckBox.
我试过通过Jquery实现,但它没有用,因为
$(document).ready(function () {
$('#<%=ChkSelectAll.ClientID %>').click(function () {
$('#<%=ChkSelectAll.ClientID %>').is(":checked")(function () {
$('#<%=ChkSelect.ClientID %>').prop('checked', true);
});
});
