Hi,
My ItemType has some 'integer' data type properties, but in server method(c#) I am not able to get the Integer Property value as int using getProperty().
int qua = this.getProperty("quantity"); This says Cannot implicitly convert type 'string' to 'int'
And same thing happening while setting an integer value to an integer property.
this.setProperty("rem_qua",4); This says Cannot implicitly convert type 'int' to 'string'
How to do this. Am I need to use Conversion methods always? If I use Convert.ToString(4) to set value, I am not seeing correct values set. Please help me
Thank you,

Int qty;
int.TryParse(this.getProperty("quantity", "0"), out qty);

Thanks Zahar,
Your solution is working well on new Item creation/update manually. I have another Item type with a life cycle, and a method added to one transition's 'Post' to update the Parent Item and set new value to quantity. At this time 'qty' is returning null.
Itemtype1- OnBeforeAdd, OnBeforeUpdate
Innovator inn= this.getInnovator();
int qty1,qty2;
int.TryParse(this.getProperty("quantity", "0"), out qty1);
int.TryParse(this.getProperty("quantity_lo", "0"), out qty2);
if(qty1==0 || qty1<qty2)
return inn.newError("Enter Valid number in Quantity");
ItemType-2- LifeCycle Transition's Post:
Innovator inn= this.getInnovator();
int qty_umr;
int.TryParse(this.getProperty("quantity_umr", "0"), qty_umr);
Item num = this.getPropertyItem("parent_item");
Item ParentItem = inn.newItem("Parent","edit");
ParentItem.setAttribute("where","[PARENT].id = '"+num.getID()+"' ");
int qty1;
int.TryParse(ParentItem.getProperty("quantity", "0"), out qty1);
int new_qty = qty1-qty_umr;
ParentItem.setProperty("qty1",Convert.ToString(new_qty));
ParentItem = ParentItem.apply();
After Promoting the Item I am getting the Error 'Enter Valid number in Quantity'. Item has Quantity as 9,Quantity LO as 4, but 'qty1' getting null value. I used inn.newError("Quantity"+qty1) to check what it is getting. Even returning null of 'qty2' also.
This is happening only when I try to update the item though the above code after Promotion. Showing correct values on manual update. How to solve this?

After actions usually don't contains any information except ID + ITEM TYPE.
What you need to do is to get databased on ID+TYPE and then process with your code
Item thisItem = this.getInnovator().getItemById(this.getType(), this.getID());
if (!thisItem.isError()) {
// USE "thisItem" instead 'this"
}
return this;
I think you have problem in this code, you need to use "num" object in TryParse and not ParentItem - because ParentItem is not yet executed against the server:
Item ParentItem = inn.newItem("Parent","edit");
ParentItem.setAttribute("where","[PARENT].id = '"+num.getID()+"' ");
int qty1;
int.TryParse(ParentItem.getProperty("quantity", "0"), out qty1);
