Expand / open / collapse hierarchy programmatically

Hi

I have a question regarding the telerik grid component particularly the hierarchy. Is it possible to open a hierarchy programmatically? For example:

I have my grid with information. Every row have more information to show. Those are stored in a hierarchy level to this row. Can I, instead of clicking the '+'-button in the row, just open it with with a method that i call e.g. in another button?

I want to make the rows clickable, i saw in the forum that this isn't yet supported for the grid. Now, I'm placing a div-Tag in the DetailTemplate of this row, and give that div a onclick-Attribute. The method the div invokes, should open the row for me respectively show the hierarchy of this row.

Is this possible?

thanks for your support.

regards

Ali Shala

Hi all,

As of version 3.0.0 of Telerik UI for Blazor, the Grid State will expose a collection of the actual expanded items instead of just their indexes - Expanded Items in the Grid State.

That said, I am now marking this thread as a duplicate of the above linked one since this enhancement could allow easy programmatic control of the hierarchy collapsing/expanding.

An update to this - the grid state lets you expand or collapse detail templates programmatically (link), so you could look at the current page of data, check the models and update the grid state as needed.

Hello Ali,

At the moment the approach with a row template where you handle the click and expanded state is the only option. A similar example is available in this blog post (see the "Master-Detail View" section).

I moved this thread to the public Feedback portal so you can Follow the status of such a feature. Here's a link for you: https://feedback.telerik.com/blazor/1442162-expand-open-collapse-hierarchy-programmatically.
