how to update a datagridview on a Parent form from a Child Form C# - sql-server

Question

I'm quite a new C# programmer,it has been a month that ive started using C#, so far so good i might say, but im curently dealing with a simple situation , but i still dont get it to work , there is the scenario :
I've 2 forms a Parent and a Child , the parent contains a Xtragrid control and a button which opens the second form and load the textBoxes in the second form with values , the second has a button to update the values in case of any changes . but i still dont get it to work , I've the following error :
MUST DECLARE A SCALAR VARIABLE at #ID
I understood the cause of the probleme but i just cant fix it ,ive have done some researches to sort myself out but i still didnt manage to make it work
the last line
da.updatecommand.parameters.addwithvalues("ID#",ds.tables["tblLesseeYW"].Rows[LesseeYW.Position][0];
I have done it but it is not working( LesseeYW which is my binding source object but it doesnt exit in the current context nor the dataset which is understandable
: there is the code need help pleaese

Answer 1

at first you should program more objective. Dont declare all variables of your class as public static. You should make them private. To get acces you have to declare Properties.
Like this:
private string name;
public string Name
{
get {return name;}
set {name = value;}
}
if you have an ID you can easily make it read-only and noone from "outside" can modify it but everyone can read.
private int leeseId;
public int LeeseID
{
get{return leeseId;}
}
So you use "getter/setter" to offer your class properties. Further not all your variables should named leese... Just name it id,name,city,pic etc. In your form you create an Object from your class. You can name this object Leese.
private Leese leese = new Leese();
leese.id = ???
leese.name = ???
Much more readable.
da.updatecommand.parameters.addwithvalues("ID#",ds.tables["tblLesseeYW"].Rows[LesseeYW.Position][0];
You wrote "ID#" but it should be "#ID". And if you build your class as i descripe at top you can use property:
da.updatecommand.parameters.addwithvalues("#ID", leese.Id);
i hope that help you.
