I am using your new tabbed comboboxes. I like them very much but when I have larger choicelist, the drawing gets very slow. How can I speed up the tabbed comboboxes?
The original intention for CGXTabbedComboBox was only small tables. For small tables it works fine to scan the choice list for the text to displayed when cells are drawn.
However, this approach can slow down the grid when used intensive with large tables (with more than 50-100 items per cell).
Therefore we have added a new user attribute that lets you specify a unique id for each choice list. This approach gives the cell some more information about the choice list so that choice list entries can be reused among cells. This allows the tabbed combobox to build an associative map and look up values in this map instead of looping through the choice list.
Check out the class reference for CGXTabbedComboBox for more details.
