I have created a control derived from Telerik.WinControls.UI.RadTreeView (Latest trial version)
I am also creating the RadTreeNode on fly..
I am setting below properties at runtime.
groupTreeView.AllowArbitaryItemHeight =
true;
groupTreeView.AllowPlusMinusAnimation =
true;
groupTreeView.DropFeedbackColor =
Color.Black;
groupTreeView.Enabled =
true;
groupTreeView.ExpandAnimation =
ExpandAnimation.Opacity;
groupTreeView.Focusable =
true;
groupTreeView.PlusMinusAnimationStep = 10;
groupTreeView.ShowExpandCollapse =
true;
groupTreeView.ToggleMode =
ToggleMode.SingleClick;
groupTreeView.UseNewLayoutSystem =
true;
but this does not show me the Expand(+) and collapse(-) sign.
Note my TreeViewXML..
<?xml version="1.0" encoding="utf-16"?>
<TreeView xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" UseDefaultSelection="true" AllowDragDrop="true" AllowPlusMinusAnimation="true" ThemeName="Office2007Black" AllowDrop="true" BackColor="Window" DropFeedbackColor="Red" LineColor="ActiveCaption">
</TreeView>
Please help..
