Application.Update(control) VS control.Update()

Hello,

I have an async method LoadDataAsync,

in this method I want to show a loader over the DataGridView while the data is loading,

I saw a previous similar question but I wanted to ask more details,

The advised solution is to call Application.Update():

this.dataGridView1.ShowLoader = true;

Application.Update(this.dataGridView1) //Call 

 

But, I saw that we can also call: this.dataGridView1.Update()

 

So which is the correct and recommended approach?

Thanks!

Hi Ali,

Application.Update () can take any Wisej object as parameter and the result is always the same:
The client syncs with the server. So this is the recommended approach to update the UI after a background task.

The 2nd call is totally unrelated to this and cannot be used as a replacement for the 1st call.

Best regards
Frank

    Okay thanks! 1 thing, Application.Update() is used only in background threads? I’m using it on the main thread since there is a delay and the client isn’t updating the UI directly after the data is fetched, sometimes it require user interaction to refresh the UI.

    It depends on where you fetch the data into. Are you using databinding? In general Application.Update() should only be necessary in background threads. Best regards, Frank
