how make loop until event in visual studio ?

i want value of label datagrid cell, until user clicks on button1. can me code ?

logic:

do .. ...  textbox1.text = datagridview1.selectedrows(0).cells(0).value.tostring until button1.click

why want loop @ first place? label value once set doesn't change. if want label value empty can try setting empty once button1.click event triggers.
