问题
I have a large winform application which we working to modify the appearance. I am replacing System.Windows.Forms.Toolbar to System.Windows.Forms.ToolStrip control. I use a custom renderer to change dropdown arrow color. with default renderer i get mouse hover effects in toolstrip but with my custom rendering it dont seem to work. Here's my code.
Tool strip initialization:I removed unnecessary code for reading comfort
this.toolStrip1 = new System.Windows.Forms.ToolStrip();
this.imageList1 = new System.Windows.Forms.ImageList(this.components);
this.toolStripDropDownButton1 = new System.Windows.Forms.ToolStripDropDownButton();
this.toolStrip1.ImageList = this.imageList1;
this.toolStrip1.ImageScalingSize = new System.Drawing.Size(55, 32);
this.toolStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.toolStripDropDownButton1
});
this.toolStrip1.Renderer = new MyRenderer();
Toolstrip dropdown button:
this.toolStripDropDownButton1.DisplayStyle = System.Windows.Forms.ToolStripItemDisplayStyle.Image;
this.toolStripDropDownButton1.ImageIndex = 0;
this.toolStripDropDownButton1.Name = "toolStripDropDownButton1";
CustomRenderer
public class MyRenderer : ToolStripRenderer
{
protected override void OnRenderArrow(ToolStripArrowRenderEventArgs e)
{
e.ArrowColor = Color.White;
base.OnRenderArrow(e);
}
}

thanks to @LarsTech for his help. I found this working. I made this below modification in renderer and in code.
Added this line in initialization
this.Toolstip1.RenderMode = ToolStripRenderMode.Professional;
CustomRenderer
public class MyRenderer : ToolStripProfessionalRenderer //Professional renderer
{
protected override void OnRenderArrow(ToolStripArrowRenderEventArgs e)
{
e.ArrowColor = Color.White;
base.OnRenderArrow(e);
}
}
