How to fetch GridTemplateColumn checkbox value using client API

[nikila]

We have a RADGrid that has 3 GridTemplateColumns
(which is have checkbox controls within them).Using client API We want to fetch the values of column 3 checkboxes to find if any checkbox is checked.This javascript should run when a button outside the grid in the page is clicked.
We are unable to fetch the value of the checkbox using the following code.

var masterTable = $find("<%=RadGrid1.ClientID%>").get_masterTableView();

var col = masterTable.get_columns()[2];

alert(col.get_uniqueName());

We are able to get the unique name but are unable to fetch the value of the check box.

We tried using Cell [0].value which is not working.

Please let us know your suggestion.
