Santosh Reddy thanks alot for the code but in custom model its difficult to examine the problem .Your hint for AbstractItemModel::createIndex worked like charm !!! . I have just inserted two line of code in model and few lines of code in my delegate class and work done.
Qt Code:
setData(changeRequest ,Qt::EditRole);To copy to clipboard, switch view to plain text mode
Above was my modification ,
Thanks again Santosh
