颜色整行而不是单个单元格

我一直试图改变Compact Framework DataGrid中一行的背景颜色，但由于.NET CF上的DataGrid与其Windows Forms对应物相比有限，因此几乎没有成功。 我实现目标的唯一成功是我现在能够根据其值改变单个单元格的背景颜色。 我无法操纵我从谷歌搜索获得的代码，因为我在C＃中不是那么好。 但是，这是我的代码：

namespace GridColor { public delegate void CheckCellEventHandler(object sender, DataGridEnableEventArgs e); public class DataGridEnableEventArgs : EventArgs { private int _column; private int _row; private bool _meetsCriteria; public DataGridEnableEventArgs(int row, int col, bool val) { _row = row; _column = col; _meetsCriteria = val; } public int Column { get { return _column; } set { _column = value; } } public int Row { get { return _row; } set { _row = value; } } public bool MeetsCriteria { get { return _meetsCriteria; } set { _meetsCriteria = value; } } } public partial class ColumnStyle : DataGridTextBoxColumn { //public event CheckCellEventHandler CheckCellEquals; public event CheckCellEventHandler CheckCellContains; private int _col; public ColumnStyle(int column) { _col = column; } protected override void Paint(Graphics g, Rectangle Bounds, CurrencyManager Source, int RowNum, Brush BackBrush, Brush ForeBrush, bool AlignToRight) { bool enabled = true; if (CheckCellContains != null) { DataGridEnableEventArgs e = new DataGridEnableEventArgs(RowNum, _col, enabled); CheckCellContains(this, e); if (e.MeetsCriteria) //g.DrawRectangle(new Pen(Color.Red, 2), Bounds.Y + 1, Bounds.Width - 2, Bounds.Height - 2); BackBrush = new SolidBrush(Color.PaleGreen); } base.Paint(g, Bounds, Source, RowNum, BackBrush, ForeBrush, AlignToRight); } } } 

现在我的表格，我有这个：

 namespace GridColor { public partial class Form1 : Form { DataSet ds; SqlDataAdapter da; private List compareValues = new List(); public Form1() { InitializeComponent(); try { addGridStyle(ref dataGrid1); compareValues.Add("OK"); compareValues.Add("Filling"); } catch (Exception ex) { MessageBox.Show("Error: " + ex.ToString()); } } private void addGridStyle(ref DataGrid dg) { DataGridTableStyle dtStyle = new DataGridTableStyle(); dtStyle.MappingName = "Test"; string connString = "Data Source=192.168.2.16,1433;Initial Catalog=TestDB;User ID=sa;Password=ABC12abc;"; SqlConnection conn = new SqlConnection(connString); conn.Open(); SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandType = CommandType.Text; cmd.CommandText = "SELECT * FROM Test"; ds = new DataSet(); da = new SqlDataAdapter(cmd); da.Fill(ds, "Test"); for (int i = 0; i < ds.Tables["Test"].Columns.Count; i++) { ColumnStyle myStyle = new ColumnStyle(i); myStyle.MappingName = ds.Tables["Test"].Columns[i].ToString(); if (i == 1) { if (ds.Tables["Test"].Columns[i].DataType == System.Type.GetType("System.String")) myStyle.CheckCellContains += new CheckCellEventHandler(myStyle_CheckCellContains); } dtStyle.GridColumnStyles.Add(myStyle); } dg.TableStyles.Add(dtStyle); } public void myStyle_CheckCellContains(object sender, DataGridEnableEventArgs e) { try { if (compareValues.Contains((string)dataGrid1[e.Row, e.Column])) e.MeetsCriteria = true; else e.MeetsCriteria = false; } catch (Exception ex) { e.MeetsCriteria = false; } } private void Form1_Load(object sender, EventArgs e) { dataGrid1.DataSource = ds.Tables["Test"]; } } } 

在我的代码的哪一部分应该改变，以便如果一个单元符合标准，它的整行将被着色而不是只有它自己的单元格？

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; } }

我没有和CF一起工作，但是我想我会把它扔出去……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。
