[英]Set the font and color of a listbox item by code in C#
I'm busy with a customized list box that I use as a register reader in c#. 我正忙于一个自定义列表框,我在c#中用作注册阅读器。 Now I want to set a determined item in a determined item with a different font and color than the rest.
现在,我想在一个确定的项目中设置一个确定的项目,其中的字体和颜色与其他项目不同。 I checked This question and from the answers I made the following code:
我检查了这个问题,并从答案中我做了以下代码:
private void myListBox_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
{
e.DrawBackground();
Font myFont;
Brush myBrush;
int i = e.Index;
if (e.Index == 3)
{
myFont = e.Font;
myBrush = Brushes.Black;
}
else
{
myFont = new Font("Microsoft Sans Serif", 9.75f, FontStyle.Bold);
myBrush = Brushes.CadetBlue;
}
e.Graphics.DrawString(myListBox.Items[i].ToString(), myFont, myBrush, e.Bounds, StringFormat.GenericDefault);
}
And call the method in my IntializeComponent() using 并使用我的IntializeComponent()调用该方法
this.myListBox.DrawItem += new System.Windows.Forms.DrawItemEventHandler(this.myListBox_DrawItem);
The call does not throw an exception whatsoever, but I see no change on the line I want to handle. 该调用不会抛出任何异常,但我看到我想要处理的行没有变化。 Is there something I am missing?
有什么我想念的吗?
You are missing one more line in your IntializeComponent()
add this: 您在
IntializeComponent()
中缺少一行,添加以下内容:
this.myListBox.DrawMode = DrawMode.OwnerDrawFixed;
before attaching an event. 在附上活动之前。
