hide line image

How to hide lines and change expand icon of treeview?

Hi,

Try hiding the default image by overriding the default CSS as shown below.CSS:

<style type="text/css">
 div.RadTreeView_Default .rtPlus
 {
  background-image: url("Images/img.gif") !important ;
 }
</style>

Try setting ShowLineImages as false to hide lines in treeview.
ASPX:

<telerik:RadTreeView  ID="RadTreeView1" ShowLineImages="false" runat="server" . .  >
</telerik:RadTreeView>

Thanks,
Shinu.
