How to keep form centered to the middle of the screen after resize ?

Add method for ResizeEnd event. In method, when ResizeEnd is fired, get current screen size (on multiple monitors, screen that contains current form) and then calculate form's position. Take a look at this example

private void Form1_ResizeEnd(object sender, EventArgs e)
    Screen myScreen = Screen.FromControl(this);
    Rectangle area = myScreen.WorkingArea;

    this.Top = (area.Height - this.Height) / 2;
    this.Left = (area.Width - this.Width) / 2;

How to calculate sum of group values using C# Dictionary?

You could just iterate through the Dictionary using foreach as follows:
public override decimal CalculateDiscount(IDictionary<myObject, int> items)
    if (items == null) throw new ArgumentNullException(nameof(items));

    foreach (var kvp in items)
        if (kvp.Key.Discount.Count == kvp.Value)
            _totalDiscount += kvp.Key.Discount.Price;
    return _totalDiscount;

How to Hiding a particular row in grid view using different buttons?

You can try this, But first you need to identify which row you wanted to hide.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)    
    Label YourControl= (Label)e.Row.FindControl("YourControl");    
    if (YourControl != null)    
        if (YourControl.Text.Trim() == "0")    
            LinkButton YourControl= (LinkButton)e.Row.FindControl("YourControl");    
            YourControl.Visible = false;    



How to Read Related Data Using LINQ/C# [one to many]?

You should be using Where instead of SelectMany:
var result = _context.PatPar.Where(m => m.FileId == id);
SelectMany is used to retrieve a collection from each item of the iterated collection. However your condition is to check if the FileId equals some id - the resulted type is a boolean. I assume what you are trying to do is return all the times that have that FileId.
To have it with the await:
var result = await _context.PatPar.Where(m => m.FileId == id).ToListAsync();

How to deserialize nested json?

Assuming your model class is defined like this:

public class DeviceInfo
    public string DeviceName { get; set; }
    public string TurbineName { get; set; }
    public string State { get; set; }
    public string TurbineType { get; set; }
    public string Version { get; set; }
Then, for the first JSON, you can deserialize like this:
var device = JsonConvert.DeserializeObject<DeviceInfo>(json);
And for the second case, you can deserialize to a dictionary, where the keys are the IP addresses, and the values are the devices:
var dict = JsonConvert.DeserializeObject<Dictionary<string, DeviceInfo>>(json2);
