Enable Persistence of Expanded/Collapsed Groups

I have two questions:

Is it possible to get and set the expanded and collapsed groups?

Hi Elio,  

 

Greetings from Syncfusion support.  

 

Query1: “Is it possible to keep the hidden groups of a grid still hidden after a Refresh of the grid?” 

 

Yes. We suggest you to achieve your requirement using GroupCollapseAll() method of EjsGrid in the DataBound event.  Refer the below code example.  

 

 

Refer the below sample for your reference 

 

Sample: https://www.syncfusion.com/downloads/support/forum/148011/ze/BlazorApp1-1460891179  

 

Refer our API documentation for your reference

Query2: “Is it possible to get and set the expanded and collapsed groups?” 

 

Currently we do not have support to get or set the state of Grouped columns in Blazor Grid.  We are validating your requirement,so we will update you the further details on 4^th October 2019. Till then we appreciate your patience.

Thank you for the reply. 

The issue is that using Grid.GroupCollapseAll();    it collapse all the groups. 

Instead I'd like to have with a grid.Refresh the collapsed groups stay collapsed and showed ones stay showed.

Actually I'm not at home so I can't upload a sample. I'll upload it asap. 

Hi Elio,  

Query: “The issue is that using Grid.GroupCollapseAll();    it collapse all the groups.  && Instead I'd like to have with a grid.Refresh the collapsed groups stay collapsed and showed ones stay showed.” 

While refreshing the EjsGrid using Refresh() method, we will re-render the each cell inside the Grid or group with updated properties. So it is not possible to store the collapsed state and expanded state of the groups. Once refreshed either you can expand all the Group using GroupExpandAll() or collapse all the Group using GroupCollapseAll() methods. It is the default behavior of the Grid.
