Call 'getSelections' method to get all the selected rows. If the row amount is greater than 1, show your error message.

Code:

var rows = $('#dg').datagrid('getSelections');
if (rows.length > 1){
  // show your error message
}

It's simple to find the count of different values in an array. Please try this code:

Code:

var cc = [];
var rows = $('#dg').datagrid('getSelections');
for(var i=0; i<rows.length; i++){
	var currency = rows[i]['currency'];
	if ($.inArray(currency, cc) == -1){	// not found
		cc.push(currency);
	}
}
if (cc.length > 1){
	alert('Found Different Currency');
} else {
	alert('No Different Currency');
}
