Hi, I have done application using Extjs 4. I have requirement need to export grid data to excel. I have grid it contains many records, showing records by group headers/summary(collapse/Expand actions ). The same thing i need to export grid data to excel the same activity need collapse/expand in excel sheet. I have tried i am able to export grid records with group headers.summary to excel, cool it is working but collapse/expand is not happening in excel sheet. I need to implement this feature by writing a code. Can anybody tell me how to achieve this one? is it possible or not by using extjs? great appreciated. Thank you.
