Refresh Table on new Column definition

[Thoemmy]

I have a question regarding refreshing the column headers after the json hass been modified dynamically with user input.

How can i refresh the column headers in Angular properly without making a page reload?

Inside revogrid the columns got updated if i change the columns and transfer it into the revogrid attribute columns.
But currently ony the width of the rows are adjusted without the column header, this only gots refreshed after page reload or if you manually resize the column header.

The refresh('all') method is undefined in angular but i guess this is only for rgRows as written in the docs.

Would be nice if ou could give me a suggestion.

Also the method updateColumns is not defined:

ERROR TypeError: Cannot read properties of undefined (reading 'updateColumns')
    at TableComponent.ngOnChanges (table.component.ts:72:21)

I don't know Angular very well, but couldn't you bind the columns to a dynamic state variable so that the columns update when you change the data in that state variable? That is how we do it in Vue.

[Thoemmy]

Yes, I do that with the source and with the columns (ngrx), the thing is that if I change the name of the column, then the name is updated immediately, but if I adjust the column width then this is only applied to the columns but not for the column header.

I hope this explaination delivers more clarity 🙈

Currently the only way i found (not the best one) is to reload the page after saving the table settings.

Hi @Thoemmy, I didn't understand your case scenario. What @MattTheCuber suggested it makes sense, you need to trigger viewport refresh for the column header to be updated. To do so you can just put new columns ref or you can make a plugin which updates column data source store items collection. This would trigger update as well but more advanced way.

@Thoemmy Could you make a sample with 1 button which is demonstrating the issue?

From your description it sounds as an issue

[Thoemmy]

@revolist i will first try the newest release and if its still remain i will setup a simple example and share it here.

Thats why i initially did not create an issue and started a discussion.

[revolist]

Sure! Thanks!

@revolist i updated the package to the newest version and the issue is solved.
