RadzenDataGrid row togglers

Hi there,
Is there a way to eliminate row toggler (arrow) at the beginning of the row and open the detail row by selecting the master row?

You can set DataGrid ShowExpandColumn to false.

if I set it false, how to display the details by selecting the row?

You can use DataGrid ExpandRow() method.

Any reference or samples on how to use ExpandRow() method?

There are plenty posts on the topic in the forum and there are hierarchical demos showing how to use ExpandRow().
