The problem why I can't get value using jquery is because the definition of id of the column:

First of, thank you for replying to my post, I am bashing my head against the wall for two days with this problem.
I will try to explane better.

When grid is in edit mode I would like to select value of column A ( edittype : select ) when inside dataEvent 'click' in column B ( column goes into inline edit mode on row select)
ColModel

Oleg thanks for the help, much appreciated. You probably saved me hours of testing

I am not sure that I full understand what you want. So I write two main problems which I see

1. You choose on the server side ids of the rows in a complex way and the values have special characters
2. The dataUrl of the 'category_entity_id' column should contain the value from the 'supplier_short_name' column from the same row.

Yes you are correct, that was my probem, but thanks to you it is almost solved

• make a simple ids
• if you have two grids on the same page don't use the same ids
• don't use for other elements on the page the same ids which could be returned from the server as rowIds

Make simple ids – of course I don't know why I was thinking that id of row must be made from columns which are unique in sql table.
