For normally checkboxlist i using these binding is work, but how to bind in gridview for each row dynamically.

        List<string> availableItems = new List<string> { "Item1", "Item2", "Item3", "Item4", "Item5" };
        List<string> selectedItems = new List<string> { "Item1", "Item3", "Item4", "Item6" };

        // add available items to checkboxlist control
        foreach (string item in availableItems)
            chkItems.Items.Add(new ListItem(item));

        // check pre-selected items
        var query = from ListItem listItem in chkItems.Items
                    join item in selectedItems
                    on listItem.Value equals item
                    select listItem;
