Checkbox in ListGrid - One selected at any given time

[ishahid]

I am using SmartClient 8.1.

I have a ListGrid with data source attached. One of the fields is boolean and it gets checked/unchecked for each row according to data it fetches.

The problem is that I want to allow only one of the check boxes in this column to be checked. All other should be unchecked.

I call a function to deselect all other checkboxes on the change event of this column. See the following code that only works for the first click.

function deselectAllOtherCheckboxes(value)
{
	if (value == true)
	{
		srec = table.getSelectedRecord();
		
		for (var i=0; i < table.data.getLength(); i++)
		{
			rec = table.data.get(i);
			if (rec.id != srec.id)
			{
				rec.checkboxField = false;
				table.refreshCell(i, 2);
				table.refreshRow(i);
			}
		}
	}
}
