Bonjour,
J'ai un combo, avec 3 evenements persos (Enter, DropDown, DrawItem). Lorsque je clic à coté, il conserve
le focus !??
comboBoxLibelleRestoria.Enter += new EventHandler(comboBoxLibelleRestoria_Enter);
comboBoxLibelleRestoria.DrawMode = DrawMode.OwnerDrawFixed;
comboBoxLibelleRestoria.DrawItem += new DrawItemEventHandler(comboBoxLibelleRestoria_DrawItem);
comboBoxLibelleRestoria.DropDown += new EventHandler(comboBoxLibelleRestoria_DropDown);
void comboBoxLibelleRestoria_Enter(object sender, EventArgs e)
{
if (comboBoxLibelleRestoria.Items.Count == 0)
{
var item = Util.ListArticles.Values.FirstOrDefault(art => art.ELEMENT_REPAS == this.labelElement.Text && art.LIBELLE_RESTORIA == comboBoxLibelleRestoria.Text);
PopulateComboboxLibelleRestoria(this.labelElement.Text);
comboBoxLibelleRestoria.SelectedItem = item;
}
}
void comboBoxLibelleRestoria_DrawItem(object sender, DrawItemEventArgs e)
{
Article item = (Article)((ComboBox)sender).Items[e.Index];
var lib = getArticleLibelleRecherche(item);
e.DrawBackground();
using (SolidBrush br = new SolidBrush(e.ForeColor))
{
e.Graphics.DrawString(lib, e.Font, br, e.Bounds);
}
e.DrawFocusRectangle();
}
void comboBoxLibelleRestoria_DropDown(object sender, EventArgs e){
ComboBox senderComboBox = (ComboBox)sender;
int width = senderComboBox.DropDownWidth;
Graphics g = senderComboBox.CreateGraphics();
Font font = senderComboBox.Font;
int vertScrollBarWidth =
(senderComboBox.Items.Count > senderComboBox.MaxDropDownItems)
? SystemInformation.VerticalScrollBarWidth : 0;
int newWidth;
foreach(Article art in((ComboBox)sender).Items){
newWidth = (int)g.MeasureString(getArticleLibelleRecherche(art), font).Width
+ vertScrollBarWidth;
if(width < newWidth){
width = newWidth;
}}
senderComboBox.DropDownWidth = width;
}
Quelqu'un aurait une idée ? un contournement ?
