Hai Sadiq,
There are 2 ways to get the data filtered based on the checkboxes.
1. If the data is limited, you can get all the data at once and then when the user checks a checkbox, filter that data and display.
In this case, you need not to hit the database again and again for the different checkbox checked option.
2. if the database if big, then you can't use the first approach as it will make the performance degrade for the whole application.
In this case, you need to get the data from the database each time when you check the checkbox.
Hope it will be helpful to you.

var dv = _dsBaseDataSet.Tables[0].DefaultView;
dv.RowFilter = "filter_criteria";
