Is it possible to selectivly change the color of an item in text. I
saw ForeColor option, but it changes the color of all the items. If it
is not possible, is there any other control list listbox where we can
see more than one item and change the color during run time.
Thanks.
i think this should do,
private void PopulateListBoxes()
{
Updating = true;
areaListBox.Items.Add(new AreaStyle("Keywords", Color.Black,
Color.White, "Standard"));
areaListBox.Items.Add(new AreaStyle("Comments", Color.Green,
Color.White, "Standard"));
areaListBox.Items.Add(new AreaStyle("Numbers", Color.Navy, Color.Yellow,
"Bold"));
areaListBox.Items.Add(new AreaStyle("Strings", Color.Maroon,
Color.White, "Standard"));
areaListBox.Items.Add(new AreaStyle("Local variables", Color.OrangeRed,
Color.White, "Bold"));
areaListBox.Items.Add(new AreaStyle("Boolean operators", Color.Black,
Color.White, "Bold"));
areaListBox.Items.Add(new AreaStyle("Signals", Color.CadetBlue,
Color.White, "Bold"));
}
private void areaListBox_DrawItem(object sender, DrawItemEventArgs e)
{
ListBox list = (ListBox)sender;
AreaStyle style = (AreaStyle)list.Items[e.Index];
Color foreColor = Color.Empty;
Color backColor = Color.Empty;
// Get the Bounding rectangle for a selected item
Rectangle SelRect = new Rectangle(e.Bounds.X, e.Bounds.Y,
e.Bounds.Width - 1, e.Bounds.Height - 1);
using(Brush backBrush = new SolidBrush(style.BackColor))
{
// Paint the item background in the wanted color
e.Graphics.FillRectangle(backBrush, SelRect);
}
using (Pen p = new Pen(Color.Empty))
{
if(e.State == DrawItemState.Selected)
{
// Set the pen color
p.Color = Color.Black;
}
else
{
// Set the pen color
p.Color = list.BackColor;
}
// Draw the selection rectangle in either black or the lisbox
backcolor to hide it
e.Graphics.DrawRectangle(p, SelRect);
}
e.DrawFocusRectangle();
using(Brush brush = new SolidBrush(style.ForeColor))
{
using(Font font = new Font(list.Font,
GetFonstyleFromName(style.FontStyle)))
{
string text = list.Items[e.Index].ToString();
e.Graphics.DrawString(text, font, brush, e.Bounds.X, e.Bounds.Y
+ 1);
}
}
}
private void areaListBox_MeasureItem(object sender, MeasureItemEventArgs e)
{
// Increase slightly to create some room for the selection rectangle
e.ItemHeight += 2;
}
