问题描述
我有一种方法可以制作网格表并从网站获取 json 数据,但该网站的数据总是在变化。所以我需要关闭我的应用程序并重新打开它以进行数据刷新。如何在不关闭并重新打开我的应用程序的情况下执行此操作?如何刷新我的页面以更新数据?
public MainPage()
{
InitializeComponent();
GetTable();
}
public void GetTable()
{
//It have my codes for create table and get datas from json
}
解决方法
尝试这样做..
public MainPage() {
InitializeComponent();
ValidateDatabase();
}
public async Task ValidateDatabase() {
//It have my codes for create table and get datas from json
await loadComponentsFromDatabase();
}
private async Task loadComponentsFromDatabase()
{
// your operation to the database,and render it to the users
// note that all components must render here and not in InitializeComponent.
// so all your components must be visible= false until you are here and make
// visible = true
}
