c# - Fragment Manager error : An object reference is required for the non-static field, method, or property -

im getting error: object reference required non-static field, method or property 'android.app.fragmentmanager.begintransaction()' in line : fragmenttransaction transaction = fragmentmanager.begintransaction();

void meditar_click (object sender, eventargs e )             {                 fragmenttransaction transaction = fragmentmanager.begintransaction();                  dialog_editar_produto dialog_editar = new dialog_editar_produto ();                 dialog_editar.show (transaction, "dialog fragment");                  dialog_editar.moneditarcomplete += dialog_editar_moneditarcomplete;              } 

what can do?

that error message indicates begintransaction not static method of fragmentmanager class. try accessing fragmentmanager object in class.

try this:

fragmenttransaction transaction = this.fragmentmanager.begintransaction();
