Hi Telerik Team,

I tried to switch the expandImage of the radPropertyGrid for several hours now. Hopefully you can help me to switch the Image ( see attachment -> red box ). In addition to this... how do I switch the backcolor of the sourrounding bars ( see attachment -> yellow boxes ).

I'm setting the content of the radPropertyGrid during runtime using the SelectedObject Property.

Thank you in advance :)

Hello Gøran,

Thank you for writing.

It is appropriate to use the ItemFormatting event in order to customize the described elements:
public Form1()
{
    InitializeComponent();
 
    this.radPropertyGrid1.SelectedObject = this;
    this.radPropertyGrid1.ToolbarVisible = true;
    this.radPropertyGrid1.ItemFormatting+=radPropertyGrid1_ItemFormatting;
}
 
private void radPropertyGrid1_ItemFormatting(object sender, PropertyGridItemFormattingEventArgs e)
{
    PropertyGridGroupElement groupElement = e.VisualElement as PropertyGridGroupElement;
    PropertyGridItemElement itemElement = e.VisualElement as PropertyGridItemElement;
 
    if (groupElement!=null)
    {
        groupElement.ExpanderElement.ExpanderItem.Image = Properties.Resources.arrow;
        groupElement.ExpanderElement.ExpanderItem.ImageLayout = ImageLayout.Zoom;
        groupElement.TextElement.BackColor = Color.Red;
        groupElement.TextElement.DrawFill = true;
        groupElement.TextElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
    }
    else if (itemElement!=null)
    {
        itemElement.ExpanderElement.BackColor = Color.LightBlue;
    }           
}

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,
