Hi James,
How can I disable the mouseover from changing the background color for ComboBoxDropDown and ComboBoxAdv. I want a fix color or want to be able to manually control this behavior to the color I want.This could be achieved by customizing the ComboBoxAdv control. The dropdown control is a ListControl. To set custom selected color, we have modified the DrawMode property and DrawItem events of the ListControl.
[Code]
public class CustomCombo : ComboBoxAdv
{
public int LastSelectedIndex = -1;
public Brush SelTextBGColor = Brushes.Gray;
public CustomCombo(): base()
{
this.ListBox.DrawMode = DrawMode.OwnerDrawFixed;
this.ListBox.DrawItem += new DrawItemEventHandler(ListBox_DrawItem);
}
void ListBox_DrawItem(object sender, DrawItemEventArgs e)
{
Brush myBrush = Brushes.Black;
if (this.LastSelectedIndex != e.Index && this.LastSelectedIndex != -1 )
{
e.Graphics.FillRectangle(Brushes.White, this.ListBox.GetItemRectangle(this.LastSelectedIndex));
e.Graphics.DrawString(this.ListBox.Items[this.LastSelectedIndex].ToString(), e.Font, myBrush, this.ListBox.GetItemRectangle(this.LastSelectedIndex), StringFormat.GenericDefault);
}
if (e.Index == this.ListBox.SelectedIndex)
{
e.Graphics.FillRectangle(this.SelTextBGColor, e.Bounds);
}
e.Graphics.DrawString(this.ListBox.Items[e.Index].ToString(), e.Font, myBrush, e.Bounds, StringFormat.GenericDefault);
this.LastSelectedIndex = this.ListBox.SelectedIndex;
}
}
is it possible to hide the down arrow at the far right?Yes. It is possible to hide the down arrow at the far right by setting the DropDown style property to Normal.
[Code]
this.comboBoxAdv1.DropDownStyle = System.Windows.Forms.ComboBoxStyle.Simple;
