Hi,

I have the native grid set up in my vue application with Vuex and having issue getting the grouping feature to work.

I am not getting a response whenever I drag a column to the column header. The dragged column just not stay in the column header, it disappears afterward.

It seems my grid isn't emitting the onDataStateChange method. Not sure what I have done wrong.

Other gird features are working fine.

Hello,

I created an example that mimics (to some extent) the code shown in your ticket and I am not experiencing any issues with grouping https://stackblitz.com/edit/vspufa?file=index.js. Can you check it out and see if I am missing anything?

Hi Ianko,

I found out why it is not working in my vue spa app (created using vue cli). It suppose to use '@datastatechange' all in small cap. However, in the web demon it is '@dataStateChange' the 'S' and 'C' is in large cap. That is the difference!

I am facing another issue with emitting '@expandchange'. The function gets emitted but it will not refresh the ui to collapse or expand the row.

Hi Ianko,

The '@expandchange' isn't working in your example too.

Hi,

I am afraid, the problem is with the computed property. Any changes to that property will not dispatch UI changes. You will need to use a simple property to bind the data. https://stackblitz.com/edit/vspufa?file=index.js

Maybe you can consider using watchers or some other mechanism to get and set data using Vuex.

Hi Ianko,

Thank you, no wonder why I am not getting update on the UI.

Can you provide me some insight how could I use watchers with the grid and Vuex?

I am new to Vue.

Hi,

Here you are an article showing various ways to watch state changes in Vuex: https://dev.to/viniciuskneves/watch-for-vuex-state-changes-2mgj.
