performance issue with summary values
posted

Hi

I am facing some performance issue after setting summary values to column.I takes 2-3 seconds to scroll horizontal or vertical.I have 500 unbounded columns and 50 rows(10 groupby rows) and 80  visible columns in area.I have added custom summary calculator to columns.

The thing which i want to achieve is to show different colors and text in each groupby row means one row with different color in each column(see attachment).I have used ICustomSummary calculator.I am returning just a string in EndCustomSummary method.I have tried to improve the performance by setting same customsummarycalculator in each column but it is still very slow.
