How do I change the color of this white line on a MenuStrip? I can't figure out what property to use.
So far I'm using this code to style all the other parts:
internal static class Clr
{
public static Color White = Color.FromArgb(255, 255, 255);
public static Color Grey64 = Color.FromArgb(64, 64, 64);
public static Color Grey86 = Color.FromArgb(86, 86, 86);
public static Color Grey127 = Color.FromArgb(127, 127, 127);
public static Color Red = Color.FromArgb(255, 0, 0);
public static Color Blue = Color.FromArgb(0, 0, 255);
public static Color Green = Color.FromArgb(0, 255, 0);
}
public class Grey64Menu
{
public void ConfigureMenu(ToolStrip toolStrip)
{
toolStrip.Renderer = new ToolStripProfessionalRenderer(new Grey64ClrTable());
foreach (var topLevelItem in toolStrip.Items)
{
ToolStripMenuItem mainItem = (ToolStripMenuItem)topLevelItem;
mainItem.ForeColor = Clr.White;
mainItem.BackColor = Clr.Grey64;
foreach (var itm in mainItem.DropDownItems)
{
ToolStripMenuItem m = (ToolStripMenuItem)itm;
m.ForeColor = Clr.White;
m.BackColor = Clr.Grey64;
}
}
}
}
public class Grey64ClrTable : ProfessionalColorTable
{
public override Color MenuBorder => Clr.Grey86;
public override Color MenuItemBorder => Clr.Grey127;
public override Color MenuStripGradientBegin => Clr.Red;
public override Color MenuStripGradientEnd => Clr.Red;
public override Color ToolStripGradientBegin => Clr.Red;
public override Color ToolStripGradientEnd => Clr.Red;
public override Color ToolStripBorder => Clr.Blue;
//Dropdown Border Color
public override Color ToolStripDropDownBackground => Clr.Grey64;
public override Color MenuItemSelected => Clr.Grey86;
public override Color MenuItemSelectedGradientBegin => Clr.Grey86;
public override Color MenuItemSelectedGradientEnd => Clr.Grey86;
public override Color MenuItemPressedGradientBegin => Clr.Grey86;
public override Color MenuItemPressedGradientEnd => Clr.Grey86;
}
An alternative method, using a custom ToolStripProfessionalRenderer , to override OnRenderItemText and eliminate that initial loop ( foreach (var topLevelItem in toolStrip.Items)
) that doesn't consider sub-items.
Also, ImageMarginGradientMiddle
should be set as well, otherwise you'll have weird results when adding sub-items. You shuld override the other middle parts, too.
You could add a public property to the custom renderer, to change the Menu text ForeColor when required.
public class Grey64Menu
{
public Grey64Menu() : this(null) { }
public Grey64Menu(ToolStrip menu) {
if (menu != null) {
ConfigureMenu(menu);
}
}
public void ConfigureMenu(ToolStrip toolStrip)
{
toolStrip.Renderer = new MyMenuRenderer();
}
}
public class MyMenuRenderer : ToolStripProfessionalRenderer
{
public MyMenuRenderer() : this(new Grey64ClrTable()) { }
public MyMenuRenderer(ProfessionalColorTable colorTable) : base(colorTable) { }
protected override void OnRenderItemText(ToolStripItemTextRenderEventArgs e)
{
e.Item.ForeColor = Clr.White;
base.OnRenderItemText(e);
}
}
public class Grey64ClrTable : ProfessionalColorTable
{
// (...)
// Fill the Image area: ImageMarginGradientMiddle is required for sub-items
public override Color ImageMarginGradientMiddle => Clr.Grey64;
public override Color ImageMarginGradientBegin => Clr.Grey64;
public override Color ImageMarginGradientEnd => Clr.Grey64;
}
Per Hans Passant's comment:
That line is the background color for the Image Margin. So I was able to fix it by adding these two lines to my ProfessionalColorTable:
public override Color ImageMarginGradientBegin => Clr.Grey64;
public override Color ImageMarginGradientEnd => Clr.Grey64;
Thank you, Hans Passant
You can do this by creating your own ColorTable, and overriding the properties you wish to change the colour of:
public class TestColorTable : ProfessionalColorTable
{
public override Color MenuItemSelected
{
get { return Color.Red; }
}
public override Color MenuBorder
{
get { return Color.Green; }
}
}
You would use it like this:
private void Form1_Load(object sender, EventArgs e)
{
menuStrip1.Renderer = new ToolStripProfessionalRenderer(new TestColorTable());
}
