Is anyone here familiar with Telerik Reporting?
If so, have you ever used their report table tool with more than 20 or more columns?
I recently created a report with 30 columns and it draws drastically slower than smaller tables. At first I thought it was from the amount of data that was being returned. When I checked the times at the database level the times were all very quick. I then reduced the amount of fields being returned, but kept the 30 columns in the report table and ran the report again. I got the exact same speed results.
Here's an example:
Qry: SELECT Col1 FROM Table1
Report table w/ 30 columns = 12-13 seconds.
Report table w/ 4 columns = 1-2 seconds.
I could see this being a problem if it was using HTML rendering extensions, but it's being displayed in a Report Viewer...
