Combox selected item matches with datagridview row and only that row disply

[Iamateur]

The user will click the book name in the combo box.
Note:
The combo box is separate from gridview i.e. it is not a part of gridview.
Then the gridview for Issuing books i.e. with the columns bid,bname,aname,data of issue,date of return shoudl be** displayed.**

The row that will be displayed in gridview is such that the bookname selected by user in the combo box should match with bname row ..
After displaying row :
On the same gridview there will be button with name "Issue" so once it is clicked then this row of gridview should get stored in the database table name "Issue" and get deleted from the databse table name "MBA"

Is this possible??
If yes, then how it can be done?
