mouseover highlight

[beavisCZ]

Hello, I have problem with mouseover highlighting. It works fine in new version but only when treeView is focused. When it lost focus, mouseover highlighting is disabled. I use it as sidebar menu so I need to work also if it is not focused. Is it solution to this?

Hello beavisCZ,

Regarding your question: There is two ways to accomplish this requirement. You can create a new theme or modify an existing theme by using the Visual Style Builder tool. Find more in this documentation article.

In addition, you can use the NodeFormatting event to achieve the desired appearance in inactive state of the control:

private void radTreeView1_NodeFormatting(object sender, Telerik.WinControls.UI.TreeNodeFormattingEventArgs e)
{
    bool isInactive = (bool)e.NodeElement.GetValue(TreeNodeElement.IsControlInactiveProperty);

    if (isInactive && e.NodeElement.IsMouseOver)
    {
        e.NodeElement.BackColor = Color.Red;
        e.NodeElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
        e.NodeElement.DrawFill = true;
    }
    else
    {
        e.NodeElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);
        e.NodeElement.ResetValue(LightVisualElement.DrawFillProperty, Telerik.WinControls.ValueResetFlags.Local);
        e.NodeElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);
    }
}

this.radTreeView1.NodeFormatting += new Telerik.WinControls.UI.TreeNodeFormattingEventHandler(radTreeView1_NodeFormatting);

I hope this helps. 

Kind regards,
