Thanks ANUTEJ,

The code workes for some conditions only actully when inserting the date and time field while parsing the csv it is not parsing this field showing error in the apex class while value mapping.

 accObj.Paid_Date__c= csvRecordData[5];
here error showes for parsing.
1. After inserting the record in the object the records are showing the vf page itself i dont want this to show here. only success msg should show.
2. second thing is the object has 2 diffrent record type i need to insert the record to the specific record type in that object how can we add for the record type in the code.

3. When csv file is empty error is not showing need to validate the file has the headers or not.
4. If suppose with the above code if csv file has diffrent headers in the it is inserting the record in the wrong field.

Please suggest me for the above. it seems urgent requirement.


please find my code.
