Can we dynamically change list of dropdown values for each row of Grid control ?

If you are using SAIL then this is not too difficult. You can use the cascading dropdown SAIL recipe to help get you started:

I am not using SAIL, is there any way using JS.

@achaugule I did the same in my internal project using the js functions in Advanced form utilities. But remember that you need to code heavily for doing so.

hey thanks for an quick update..
I have used window.FormAPI.updateDropdownValues() function of Advance form utilities for normal dropdowns in my earlier projects. Does the same function work for grid dropdown as well?

@achaugule Usage of updateGridDropdownValues is suggested in your case. Attached the js file of Advanced form utilities which includes the functions in order to operate over a gird effectively.

FormsExt.js

Thanks a lot :) its working. Just one last doubt, there is change event associated with dropdown, can we fetch row id for which we have changed dropdown value.

Please make use of this.index OR window.FormDesigner.lastRowEvent.

window.FormDesigner.lastRowEvent works for me, Thank you very much.

:) Great!!
