As a developer user, I need to add a Markdown Editor control to my Blazor UI application so that I can capture and display markdown-compliant text input.
I am editing parent and child records in the hierarchy grid. I can edit parent and child records without issue. The only problem I have now is this; when I click edit on a child record, then collapse the parent, the edit of the child record is lost or cancelled but there is no event I can see to use to put things back in non-edit mode.
I enable buttons and links in non-edit (view) mode and disable them when editing a record.
So, is there an event or some way to know the user is collapsing or expanding a parent record?
This error appears after update 15, in 14.1 it works correctly.
This error occurs from the FilterMode set to FilterRow. As a workaround, until the fix is implemented, you could use the FilterMenu instead.

If I'm filtering a column containing enum values I expect a dropdown of available values to choose from (as it is the case when filtering a grid using telerik UI for .net core).
Unfortunately with Blazor Grids the filter for Enums displays a numberbox. This is not usable since the user does not know the IDs for the enum values.
Please let me know how I can get the filter to let the user choose from the available enum values!
how to select ALL items in the grid data source using GridCheckboxColumn in the grid header when grid is in Virtual scroll mode?
When I click on the GridCheckboxColumn in the grid header it selects only the items in the current visible page but I would like to select all items in the grid data source.
Selecting all items in the grid (not only visible ones) is a must have feature and current behavoiur is kind of misleading because the user would expect that all items are selected.
ADMIN EDIT: This has been available since 2.10.0 through the SelectAllMode parameter of the selection column.
ADMIN EDIT: Check the source code and comments in it from the following demo to see how to bind the grid to a DataTable: https://demos.telerik.com/blazor-ui/grid/data-table. You can also examine it offline - the entire demos project is available in the "demos" folder of your installation
I would like to be able to supply a DataTable with an arbitrary amount of columns to the grid and display them all without declaring them all. This should also allow paging, sorting, filtering. At the moment binding to a DataTable is not supported, only IEnumerable collections are.
At the moment, here's the closest I can get, sorting and filtering throw errors so they are disabled.
