我的代码有问题吗？ [英] Is there something wrong with my code?

问题描述

我有一个网格，我想每隔X秒绑定一次，但是计时器不会等到进程完成，它只是一遍又一遍地执行，我甚至尝试创建一个变量，并将其用作标志，但它似乎没有工作，这里是我的代码（问题不在我的代码背后，如果它有任何问题必须在这里，因为我唯一要做的是在tick事件中绑定网格）：

I have a grid that I want to bind every X seconds, but the timer is not waiting until the process is done, it's just executing itself over and over, I even tried creating a variable, and use it as a flag, but it doesn't seem to be working, here is my code(the problem is not in my code behind, if there's any problem it has to be here, because the only thing i do is bind the grid in the tick event):

推荐答案

你能查看一个标志吗？你的Timer1_Tick（）

- >如果为true GetLatestDataForGrid（）

- >否则忽略

- >设置flag = False



并在完成gridLoad后将该标志设置为TRUE。

Can you check a flag in your Timer1_Tick()
-> If true GetLatestDataForGrid()
-> Else ignore
-> Set flag=False

And set that flag to TRUE after completion of your gridLoad.
