Extract values from vary controls and Write it on XML
This has found in forum who shared the problem and solution as mentioned above title. Background: A form contains many controls, such as TextBox, ComboBox and etc... Then, we need to extract the value from these options. The code example is as below: foreach ( Control control in this . Controls ) { //here 'this' is representing the form you want to iterate through //you can check whether it is a combobox or a text box if ( control . GetType () == typeof ( Combobox )) { //this is a combo box } else if ( control . GetType () == typeof ( Textbox )) { //this is a text box } } This is a nice example as for beginner like me ^^/ Link: http://stackoverflow.com/questions/6400382/how-do-i-extract-values-from-controls-and-write-it-on-xml
