I am using a DataGridPro component with different columns.
One one the columns is defined like this:
This issue is that I am trying to understand why the row is not available in the valueOptions prop of the column definition.
I would like to be able to populate the choices based on a list that is available on the row in another field.
But I get this error when I try to read the row:
Can you please help? The grid is populated with lots of rows coming from an api fetch.
Every other column is working fine accept this one.
Thank you.
I discovered that it was my bad. My column object was used twice with different parameters and so, yes, the row was not available for the second case.

I was trying to make a dynamic table in Flutter/Dart where I can add new rows , delete some of them and edit their content .
I tried different packages but I couldn't figure out a way to make it .
Can someone help me ?
I have the following problem:
customer wants Excel like behaviour on a table. When double-clicking on the space between two column-headers, the column should be sized like the biggest text inside that column.
Question: Is there a build in GXT function to add a Handler to the space between two column headers? I havent found sth. like that, browsing the documentation of grid...
Additional Information: GXT: 3.0.1 GWT: 2.5.1
Thank you very much!
No, it doesn't seem GXT exposes any handlers for actions on the column separators. A possible solution would be to have a option in the column drop down. There is an aricle about that here: http://greatlogic.com/2014/06/02/autofit-column-width-in-a-gxt-grid/
I want to create a celltable which column can have costumn widgets like rating.
After researches, i find that i have to create a class that extends AbstractCell, But it isn't very clear.
Can somebody help me, or is there any tutorial for that?
