Sum Values Of 1 Column in a Datagrid??

[Neumee]

Is there a way...I can sum all the values of one column of a datagrid and display the total in a label??

So...I have a column in my datagrid called "PAR_AMOUNT"....so for every item in the datagrid...I want to sum the values of the column "PAR_AMOUNT" and place the total in a label??

Ex.

Datagrid...
Item 1 "567"
item 2 "200"
item 3 "300"


Label.text = "1067"

Thanks in advance!!
