如何创建一个突出显示中间选定文本c＃win的列表。形成 [英] How to create a list that highlights middle selected text c# win. form

问题描述

我想创建一个列表，搜索并检索列表中与搜索条件匹配的所有数据（要搜索的文本可以出现在列表的字符串 start，middle，end ）< br $> b $ b

我想要的样本图像实现



现在，情况是我可以自己处理搜索部分但我不知道如何创建控件在c＃win中突出显示列表中的匹配文本。 form

解决方案

为DrawItem添加一个事件处理程序

  this  .ComboBox1 =  new  ComboBox（）; 
  this  .ComboBox1.DrawMode = System.Windows.Forms.DrawMode.OwnerDrawVariable; 
  this  .ComboBox1.DrawItem + =  new  DrawItemEventHandler（ComboBox1_DrawItem）; 
 
  private   void  ComboBox1_DrawItem（对象发​​件人，
 System.Windows.Forms.DrawItemEventArgs e）
 {
  //  使用e.Graphics属性绘制自己的文本 
  //    
  //   e.Graphics.DrawString（...））;  
 
} 
 

这里有一个MSDN示例：ComboBox.DrawItem

I want to create a list that searches and retrieves all the data in list which is matching the searching criteria (the text to search can appears anywhere in the list's string start,middle,end)

Sample Image Of What I Want To Achieve

Now, the situation is i can handle the searching part myself but i dont know how to create control which highlights the matched text in the list in c# win. form

解决方案

Add one event handler for DrawItem

this.ComboBox1 = new ComboBox();
this.ComboBox1.DrawMode = System.Windows.Forms.DrawMode.OwnerDrawVariable;
this.ComboBox1.DrawItem += new DrawItemEventHandler(ComboBox1_DrawItem);

private void ComboBox1_DrawItem(object sender,
                                System.Windows.Forms.DrawItemEventArgs e)
{
    // use e.Graphics property to draw your own text
    //
    // e.Graphics.DrawString(...));

}

There is a MSDN example here: ComboBox.DrawItem
