Hi,
I have developed an excel2007 add-in in which I have added a button to ribbon. On button click I am opening windows form in which I have embedded WPF chart control.
Chart control takes selected cells and puts that in an ObservableCollection which is binded to chart.
Now the problem is, when the form is displayed for first time. It takes 15-20 seconds to the display the form and wpf chart. After that it works fast.
