I have a Tile Layout with a TelerikButton in the HeaderTemplate and it does not fire unless I click on the button more that once. This seems to have started with v3 of the controls.
<TileLayoutItem ColSpan="13" RowSpan="12" Class="scrollableTile">
<HeaderTemplate>
<h5 class="k-card-title d-inline-block">Hours</h5>
<TelerikButton Class="float-end" Icon="save" Title="Save" OnClick="SaveHoursAsync"></TelerikButton>
</HeaderTemplate>
<Content></Content></TileLayoutItem>
Yes. Thanks.
I marked my post an answer for anyone hitting the same behavior to see easier. Sorry for orphaning your comment a little ^_^
