.net - Capture single row in a datagridview -

i have .net windows app.

i have datagridview has few rows in it. had added column containing buttons allow user edit row. pops new form/dialog - edit form.

// add cellclick handler handle clicks in button column. dgv.cellclick += new datagridviewcelleventhandler(dgv_cellclick); 

the code fires is:

private void dgv_cellclick(object sender, datagridviewcelleventargs e) {         if (e.columnindex == buttoncell)     {         // id number         int number = convert.toint32(dgv.rows[e.rowindex].cells[0].value);           editform edit = new editform(number);         edit.showdialog();                        } } 

problem

my edit form displays (correctly). make changes, , close form. loads again! same number of rows in grid. ie. fires code above once each row in datagrid.

how can prevent this? there more elegant solution?

i make sure you're not registering cellclick event more once.

i.e., you're not calling code more once (like each time add row dgv):

dgv.cellclick += new datagridviewcelleventhandler(dgv_cellclick);
