Getting distinct values into a combobox

[rhmorgan]

OK I am an extjs beginner. I have loaded up a store which I want to use for a grid. I also want to have combo boxes above the grid which filter the data. I want to use the same store to build the combo boxes; however, I cannot seem to be able to figure out how to remove the duplicate values. How do I get distinct id, name values from the store into the combobox? thanks to anyone who can help.

I assume your combobox is not part of the grid columns. What you could do is to implement one of the "before*" events of the combobox (I guess beforequery or expand), then use the store's "each" function and loop the store records to make a distinct list for your combobox.

I hope this helps.

BTW: Here is a very good guide if you are new to using the combobox component:
