Tags: Data Grid |
I am working on a grid
that potentially can be very large for our users. It uses a lot of the built-in
features Syncfusion provides. I would like to make it so they can arrange the Grid in a
way like (move columns around, remove or add columns, group by, sort etc...) and then
be able to save that modified grid as a view that can be selected anytime they
are using our tool. potentially they could have multiple view saves they could
load at will.
The piece I am having
trouble with is getting the grid state, and reloading it on the page. I would
be saving the state to a field in a firebase DB to be called on anytime it is
needed. I have read and seen the documentation on state persistence and
saving it to local storage, and have tried to use that to save to our DB but
have been unsuccessful. I am hoping I am hoping to find an additional example,
or documentation of something like this.
