Hi,
could you please be so kind and show me in your grid style (I'm using Windows8 theme) name of style/template where I can remove borders of indent cell on detail row (marked with orange). I want also remove background and border of indent cell on second and third grouping row (marked with dark red) when I have more grouping columns. I was already overide style of first grouping row (in my case MainClassification) but when I have second and third grouping I have indent cell which I want override too. I have Collapsed "RowIndicatorVisibility" and "RowDetailsVisibilityMode" properties just for your information. My telerik version is 2016.Q2. Thank you very much for your help.
