Occurs when DrawMode is OwnerDraw, and an item needs to be painted in the drop-down suggestion window.

Event Data

The event handler receives an argument of type DrawItemEventArgs containing data related to this event. The following DrawItemEventArgs properties provide information specific to this event.

Example

This is an example handler for the DrawItem event. It draws the background of the highlight bar using a gradient fill, and displays the file size or "Folder" beside each item in the list (depending on what it is). We are assuming in this example that files are being suggested in the drop-down suggestion window.

[C#]

private void autoComplete1_DrawItem(object sender, Skybound.AutoComplete.DrawItemEventArgs e)
{
    bool selected = (e.State & DrawItemState.Selected) == DrawItemState.Selected;
    
    if (selected)
    {
        // make a gradient highlight brush
        using (Brush brush = new LinearGradientBrush(
            e.Bounds, SystemColors.Highlight, ControlPaint.Light(SystemColors.Highlight),
            LinearGradientMode.Vertical))
        {
            e.Graphics.FillRectangle(brush, e.Bounds);
        }
    }
    else
    {
        e.DrawBackground();
    }
    
    // draw image and text
    e.DrawImage(e.Bounds.Location + new Size(4, 0));
    e.DrawText(e.Bounds.Location + new Size(22, 1));
    
    // get the full path to the file
    string fileName = e.GetFullPath();
    if (fileName != null)
    {
        string extra;
        
        // retrieve information about the file
        FileInfo info = new FileInfo(fileName);
        
        if ((info.Attributes & FileAttributes.Directory) == FileAttributes.Directory)
        {
            extra = "Folder";
        }
        else
        {
            extra = (info.Length / 1024).ToString("#,##0") + " KB";
        }
        
        // draw the additional information directly in front of the other text
        Point location = new Point(e.Bounds.X + e.MeasureText().Width + 28, e.Bounds.Y + 1);
        
        e.DrawText(location, extra, selected ? Color.LightGray : Color.Gray);
    }
}

[Visual Basic]

Private Sub autoComplete1_DrawItem(ByVal sender As Object, _
    ByVal e As Skybound.AutoComplete.DrawItemEventArgs)

    Dim selected As Boolean = ((e.State And DrawItemState.Selected) = DrawItemState.Selected)

        Dim location As Point = New Point((e.Bounds.X  _
                        + (e.MeasureText.Width + 28)), (e.Bounds.Y + 1))
        
        e.DrawText(location, extra, IIf(selected, Color.LightGray, Color.Gray))
