C#学习教程：颜色整行而不是单个单元格分享

好吧，我回去找了几年前的代码，我在台式机上做了这个，然后是更高级的DataGridView出来之前等等。

首先，本教程是Microsoft 自定义Windows窗体DataGrid的 ，它解释了如何突出显示整行。

我查看了我的代码，我必须为每个列添加一个自定义列样式，向我处理的主窗体发出一个事件，然后确定该记录的正确颜色。 然后，我设置args.Color属性，DataGridColumn将绘制正确的颜色。 所以是的，你必须让每一列成为你的自定义formtable类，然后你的应用程序逻辑可以处理事件，获取记录数据并确定颜色

**更新：这是一个简单的例子**

 public partial class Form1 : Form { FormattableTextBoxColumn firstNameColumn = new FormattableTextBoxColumn(); FormattableTextBoxColumn lastNameColumn = new FormattableTextBoxColumn(); public Form1() { InitializeComponent(); // add first name col firstNameColumn.MappingName = "FirstName"; dataGridTableStyle1.GridColumnStyles.Add(firstNameColumn); firstNameColumn.SetCellFormat += new FormatCellEventHandler(ColumnSetCellFormat); // add last name col lastNameColumn.MappingName = "LastName"; lastNameColumn.SetCellFormat += new FormatCellEventHandler(ColumnSetCellFormat); dataGridTableStyle1.GridColumnStyles.Add(lastNameColumn); // This just sets up a dummy data source, since I don't have a database in this example List peopleList = new List(); peopleList.Add(new PersonTest { FirstName = "Alan", LastName = "QQQQQ", HighlightPerson = true }); peopleList.Add(new PersonTest { FirstName = "John", LastName = "Smith", HighlightPerson = false }); BindingSource peopleDataSource = new BindingSource(); peopleDataSource.DataSource = peopleList; dataGridTableStyle1.MappingName = peopleDataSource.GetListName(null); dataGrid1.DataSource = peopleDataSource; } // I'll cache this brush in the form, just make sure to dispose it (see designer.cs disposing) SolidBrush highlightBrush = new SolidBrush(Color.Yellow); // here is the event you can handle to determine the color of your row! private void ColumnSetCellFormat(object sender, DataGridFormatCellEventArgs e) { if ((e.Source.List[e.Row] as PersonTest).HighlightPerson) e.BackBrush = highlightBrush; } // example test class public class PersonTest { public String FirstName { get; set; } public String LastName { get; set; } public bool HighlightPerson { get; set; } } } 

和自定义数据网格列

 public class FormattableTextBoxColumn : DataGridTextBoxColumn { public event FormatCellEventHandler SetCellFormat; protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight) { DataGridFormatCellEventArgs e = new DataGridFormatCellEventArgs(rowNum, source); e.ForeBrush = foreBrush; e.BackBrush = backBrush; OnSetCellFormat(e); base.Paint(g, bounds, source, rowNum, e.BackBrush, e.ForeBrush, alignToRight); } private void OnSetCellFormat(DataGridFormatCellEventArgs e) { FormatCellEventHandler handler = SetCellFormat; if (handler != null) handler(this, e); } } 

您还需要此DataGridCellEventArgs.cs

 public delegate void FormatCellEventHandler(object sender, DataGridFormatCellEventArgs e); public class DataGridFormatCellEventArgs : EventArgs { public int Row; public CurrencyManager Source; public Brush BackBrush; public Brush ForeBrush; public DataGridFormatCellEventArgs(int row, CurrencyManager manager) { this.Row = row; this.Source = manager; } } 

这是一个示例项目：

我没有和CF一起工作，但是我想我会把它扔出去&＃8230;&＃8230;如果你可以访问单元格，那么这行不是NamingContainer吗？ 如果是这样，您可以向上钻取行并应用样式或使用CSS类添加属性。
