Hi Hadhber,
Thank you for your patience.
Issue:
I will change the background color and font style of a selected nodeYou can change the selected node background color and font style through the style sheet of the treeview. The following code snippet is used to achieve this behavior:
CSS/TreeStyle.css style sheet
.Act_TextCont
{
background-color: red;
font-family: Arial;
font-size: 13px;
padding-left: 5px;
color:White;
height:15;
text-align:center;
}
Please refer the sample in the below link which illustrates the above:
