如何使DataGrid中的每一行记录显示不同的背景颜色?(急)

Question

DataGridTableStyle style=new DataGridTableStyle();
style.MappingName=ds.Tables[0].TableName;
style.AlternatingBackColor=System.Drawing.Color.Lavender;;

Answer 1

我不是说怎么为他上颜色,而是问,如何区分两行.<一行白一行黑,如何判断行颜色切换?>

public class DataGridColoredTextBoxColumn : DataGridTextBoxColumn 
 
     { 
 
          protected override void Paint(System.Drawing.Graphics g, 
 
               System.Drawing.Rectangle bounds, System.Windows.Forms.CurrencyManager 
 
               source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush 
 
               foreBrush, bool alignToRight) 
 
          { 
 
          // the idea is to conditionally set the foreBrush and/or backbrush 
 
          // depending upon some crireria on the cell value 
 
          // Here, we color anything that begins with a letter higher than 'F' 
 
               try{ 
 
                    object o = this.GetColumnValueAtRow(source, rowNum); 
 
                    if( o!= null) 
 
                    { 
 
                         char c = ((string)o)[0]; 
 
                         if( c > 'F') 
 
                         { 
 
                         // could be as simple as 
 
                         // backBrush = new SolidBrush(Color.Pink); 
 
                         // or something fancier... 
 
                              backBrush = new LinearGradientBrush(bounds, 
 
                                   Color.FromArgb(255, 200, 200), 
 
                                   Color.FromArgb(128, 20, 20), 
 
                                   LinearGradientMode.BackwardDiagonal); 
 
                              foreBrush = new SolidBrush(Color.White); 
 
                         } 
 
                    } 
 
               } 
 
                catch(Exception ex){ /* empty catch */ } 
 
               finally{ 
 
                    // make sure the base class gets called to do the drawing with 
 
                    // the possibly changed brushes 
 
                    base.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight); 
 
               } 
 
          } 
 
     }

Answer 5

在DataGridResult_ItemDataBound事件里用  e.Item.ItemIndex 整除2判断

Answer 6

请问DATALIST有类似的事件吗？再一个,如何通过此事件更新记录中的其它控件,假设,显示每条记录中有一个LABEL控件,如何让此控件显示的数为e.Item.ItemIndex,现二个,背景颜色如何从此事件中调用.也有每条记录的背景颜色.

Answer 8

你是要一行黑一行白？还是每一行都不同，是前者还有办法，
this.dataGrid.AlternatingBackColor = System.Drawing.Color.LightGray;
