Question

C#, visual studio 2015, MS Access database : the datagridview1 as below:
ID	Entry Date	Status	FirstName	LastName	Father Name	Mother Name	ChildrenNo
1	20/7/17	Unmarried	Rohim	Mia	Ajgor	Korimona
4	23/7/17	Unmarried	Kuddus	Mia	Abdullah	Zerina
5	24/7/17	Married	Nitai	Pada	Sumon	Khodeja	4
6	25/7/17	Married	Salam	Istiak	Sahabuddin	Ojela
7	26/7/17	Married	Alom	Mahabub	Mijan	Sahnaj	3
8	27/7/17	Married	Mitu	Kita	Samim	Sorifa
					ComboboxStatus	datetimepricker1
					btnFind	datetimepricker2
When I will select comboboxstatus as Married, dtp1 as 24/7/17, dtp2 as 27/7/17, If I press btnFind button then I get the result that ChildreNo column is not empty and datagridview will show the result as:
ID	Entry Date	Status	FirstName	LastName	Father Name	Mother Name	ChildrenNo
5	24/7/17	Married	Nitai	Pada	Sumon	Khodeja	4
7	26/7/17	Married	Alom	Mahabub	Mijan	Sahnaj	3
Please provide me any link or example or simple code.
