    When expanding all kendo grid rows, it is very slow.

    The detailtemplate is very simple, but it is still so slow. Any suggestions how to make it faster?

    Hi Jaanus,

    I understand that this functionality might be important for your project, however, usually, we do not recommend expanding all rows at once. This could lead to the observed slow performance. For the time being, there is no way to expand all the rows faster.

    The reason for the slow performance comes from the fact that, for every HTML row in the table, a new row is created and appended:

    Try our brand new, jQuery-free Angular components built from ground-up which deliver the business app essential building blocks - a grid component, data visualization (charts) and form elements.
