Tkinter two interlinked Comboboxes where options of second is taken based on Selection of first

   • Tkinter Combobox to select Option or ...   Part I Details Tkinter Combobbox    • Tkinter Combobox options taken from M...   Part II Options from JSon , CSV , MySQL or SQLite database table : We used MySQL database student table to populate the options of first dropdown combobox. User can select one option from the combobobx one and on selection the second list box is dynamically populated with the matching data of the first selected option. In our example we are using student table and in first combobox all unique class names are used. User can select one of the several classes from the first list and after selection the trace() method of string variable will trigger one function my_upd(). Inside this function we will first collect the matching data (student names) from the table for the selected class by executing the query. Using this record set we will create one list with the matching names. This name we will connect to value option of the 2nd combobox. This way we will reflect the changes based on the selection of the first drop down list box. www.plus2net.com/python/tkinter-Combobox-linked.ph… Copy the SQL dump to create student table www.plus2net.com/sql_tutorial/sql_student_dump.php #tkinter #python #gui #dependantcombobox #linkedcombobox #dynamicoptions #plus2net #addingoptions #linkeddropdown #databaseoption
