Winform: How to display form controls only when all controls have been loaded?

I have a windows form with several labels and buttons. Eg:

Name : ____
Age  : ____
Phone: ____

btnCancel |  btnModify

The values of the labels (____) are fetched from database on page load. When I open this form labels such as Name,Age,Phone get loaded first, then ____ get updated when query returns result, and then btnCancel and btnModify get displayed. I want entire form to load at once when the value have been fetched. It would also be great if I could give some kind of indication that system is processing.

You could put all of the controls into a "panel" and then set the Panel.Visible to false and when the load and update are complete set the Panel.Visible to true.

The easiest way to signal a busy state is to use Control.UseWaitCursor property. You should be doing the actual loading in another thread.

For example, inside a Form or a UserControl:

panel1.Visible = false;
this.UseWaitCursor = true;
Task.Run(() => { 
    var data = LoadTheData();
    this.BeginInvoke((Action)(() =>
    {
        labelName.Text = data.Name;
        panel1.Visible = true;
        this.UseWaitCursor = false;
    }));
});
