*KR**다른 텍스트 색상 또는 배경색으로 셀 값을 판단 할 수있는 -
 실버 DataGrid를 사용하는 경우, 그것은 종종 수요를 발생합니다.
WPF와 Silverlight 바인딩 및 동작의 템플릿 원칙에 처음 익숙하지
않은, 참으로, 계몽에 오신 것을 환영합니다, 탐험 나는 반면에
세 가지 접근 한 메모를 마무리 해요 곳을 찾기 위해 어떤 노력을했다.

DG1, DG2, DG3 다음 실버 라이트 프로그램에서 세 가지 데이터
격자를 넣어. 빨간색 마이너스 표시하면 여러 지점의 소스 데이터를 
 각 레코드 쇼에 ScoreB 두 점수와 ScoreA을 가지고, 우리는 점수> 
 0을 달성하기 위해 희망, 텍스트, 녹색입니다. DG1, 2,3 색상
부정적인 점수에 따라 효과를 달성하기 위해 각 사용 다른 방법 :

DG1 : 사용 DataGridTemplate, TextBlock에, ScoreA / B에 바인딩있는
foregroud 숙박 시설은 넣어하지만 IValueConverter를 추가 빨간색이나
녹색의 번호를 설정합니다

DG2 : 셀의 시각적 요소를 제거하는 DataGridTextColumn.GetCellContent (DataGridRowEventArgs.Row) 방법을 사용하여 DataGrid.LoadingRow
 이벤트, DataGridTextColumn을 사용합니다 
(오른쪽 DataGridTextColumn을 우려 TextBlock의 경우),
TextBlock에, DataGridRowEventArgs.Row로의 변환. 반사 기술은
 자신의 긍정적이고 부정적인 속성에 따라 TextBlock의
전경을 ScoreA 또는 ScoreB를 제거하고 조정과 함께 
DataContext에 정보 객체를받을 수 있습니다. 반사 교체 하드 
 코딩이나 경우 장소를 전환 할 수 있습니다 
(예를 들어 : 만약 (c.Header.ToString () == 
 "ScoreA") V = sd.ScoreA;), 또는 당신은 바인딩을 사용 할 
 수 있습니다 + 변환 방식을 데이터 속성 전경 값은 
 (이 방법 DG3는 보여줍니다) 함께 묶어.

DG3 : 사용자 정의 ScoreColumn, 그것은 긍정적이고 부정적인
전환의 데이터 값으로 수행 할 수 있도록  
DataGridTextColumn을 상속하지만, GenerateElement  
 ()를 재정의 Foreground 속성 플러스 바인딩하기 전에
TextBlock에 반환합니다. 또한, GenerateElement ()는 재미있는  
게임을 많이 변경할 수 동적 인 시각적 요소의 조합을 표시  
할 반환 할 수 있습니다   ****KR**아래 봐***

**When using Silverlight DataGrid, it is often encountered a demand -
to be able to determine the cell value by a different text color or 
 background color. Initially unfamiliar with WPF and Silverlight 
Binding and Template principle of operation is, indeed, took some 
effort to explore, to find out where I'm finishing three different 
approaches, one notes, on the other hand are welcome to enlighten.

In the following Silverlight program, put three DataGrid: dg1, dg2, 
 dg3. Source data for the multiple points, each record have ScoreA 
with ScoreB two scores in the show, we hope to achieve scores of> 
 0:00 text is green, if negative displayed in red. dg1, 2,3 each use a 
different method to achieve the effect according 
 to color negative score:

dg1: Use DataGridTemplate, put TextBlock, Foregroud property 
Binding to ScoreA / B, but add a IValueConverter will turn 
red or green numbers

dg2: Use DataGridTextColumn, in DataGrid.LoadingRow event, using DataGridTextColumn.GetCellContent (DataGridRowEventArgs.Row) way
to remove the visual elements of the cell (right DataGridTextColumn 
concerned, is TextBlock), its transformation into a TextBlock,
DataGridRowEventArgs.Row. DataContext may obtain information 
object with Reflection techniques remove ScoreA or ScoreB, and 
then adjust the TextBlock Foreground according to their positive 
and negative attributes. Reflection can switch places with  
Hardcoding replaced or if (for example: if (c.Header.ToString () == 
 "ScoreA") v = sd.ScoreA ;), or you can use Binding + Converter  
way the foreground with the data attribute value tied together 
(this practice dg3 demonstrates).

dg3: Customizing a ScoreColumn, inherited from  
DataGridTextColumn, but override GenerateElement (), returns a
TextBlock before the Foreground property plus the Binding, so that 
it can do with the data values ​​of the positive and negative switching.  
 In addition, GenerateElement () can return to display dynamic visual  
 element combinations that can change a lot of interesting gameplay

在使用Silverlight DataGrid時，很常遇到一項需求--要能依儲存
格值決定不同的文字顏色或背景色。起初不熟WPF及Silverlight
Binding及Template運作原理，著實花了一些功夫摸索，這裡整理
找出的三種不同做法，一方面備忘，另一方面歡迎大家指教。
在以下的Silverlight程式中，放了三個DataGrid: dg1, dg2, dg3。
資料來源為多筆分數資料，每筆記錄各有ScoreA與ScoreB兩個 
分數，在顯示時，希望做到分數>0時文字為綠色，若為負數則以 
紅色顯示。dg1,2,3各使用不同的方法達成依分數正負變色的效果:
dg1: 使用DataGridTemplate，放入TextBlock，Foregroud屬性 
Binding至ScoreA/B，但加掛IValueConverter將數字轉為紅色或綠色

dg2: 使用DataGridTextColumn，在DataGrid.LoadingRow事件中，
利用DataGridTextColumn.GetCellContent  
(DataGridRowEventArgs.Row)的方式取出儲存格中的視覺元素 
(對DataGridTextColumn而言，就是TextBlock)，
將其轉型為TextBlock，DataGridRowEventArgs.Row.
DataContext可取得資料物件，用Reflection的技巧取出ScoreA
或ScoreB，再依其正負調整TextBlock的Foreground屬性。
Reflection的地方可以用switch或if配合Hardcoding取代(例如:  
if (c.Header.ToString() == "ScoreA") v = sd.ScoreA;)，
或者可以用Binding + Converter方式將前景色跟資料
屬性值綁在一起(此做法dg3會示範)。

dg3: 自訂一個ScoreColumn，繼承自DataGridTextColumn，
但覆寫GenerateElement()，傳回TextBlock前，為Foreground
屬性加上Binding，使其能隨資料值的正負做切換。另外，
GenerateElement()可以動態傳回要顯示的視覺元素組合，
可以變化出許多有趣的玩法                       **
