Hi

is the drawitemstate of drawitem method of comobox defferent for Windows XP
and Windows 2003, how does one solve such problems

TIA
Barry
 
if you echo the e.state.ToString() of the drawitem event it shows

"None" or "Selected" in Windows 2003

"NoAccelerator, NoFocus" or "Selected, NoAccelerator, NoFocusRect" in
Windows XP
 
I prefer to ignore such EXPERT comments

.NET doesn't use messages, it uses events. And they will be the same for
a given .NET version, regardless of OS version. There's no "problem" to
solve.

Since the DrawItemState enumeration has a flags attribute, the values can be
"or'ed" together. This could occur regardless of the OS version. It appears
the defaults, probably due to visual styles or themes, are different between
the OS's in question.

Thanks for your reply

MSDN suggests the following (not tried it myself, but i solved the problem
in my app)

// Draws the backgrounds for entire ListView items.
private void listView1_DrawItem(object sender,
DrawListViewItemEventArgs e)
{
if ((e.State & ListViewItemStates.Selected) != 0)
{
// Draw the background and focus rectangle for a selected item.
e.Graphics.FillRectangle(Brushes.Maroon, e.Bounds);
e.DrawFocusRectangle();
}
else
{
// Draw the background for an unselected item.
using (LinearGradientBrush brush =
new LinearGradientBrush(e.Bounds, Color.Orange,
Color.Maroon, LinearGradientMode.Horizontal))
{
e.Graphics.FillRectangle(brush, e.Bounds);
}
}

// Draw the item text for views other than the Details view.
if (listView1.View != View.Details)
{
e.DrawText();
}
}

Correct, the drawing for a listviewitem would be handled similar to that for a
combobox. The flags are or'ed together in both cases. Glad you got it
working.
