if you obtained grid PRO edition, you may try to use “combo” type instead of “coro”. “combo” is based on dhtmlxCombo that support autocomplete with dynamic loading:
if you want to show all options at once - “combo” excell will not resolve the problem. The solution is using dynamic loading when options are loaded when characters are types in editor.
Moreover… How many cells have “combo” type ? You defined data for a cell - it would be better to define the type for a column if all cells in the column have the same type.
yes i want to show all the options at once. more then 4 cells have combo type, each combo contains more then 2000 options and all the cells in a single column have same type.
