編輯：我已經被帶領注意到問題不在第一行，但所有行都在鼠標滾動後移動。Datagrid滾動時奇怪地行事
我非常清楚，這是一個棘手的問題，這可能會導致我的不完整或者太私人的問題。這就是說我會盡可能清楚地解釋它。 我有一個由我通過例程構建的數據網格。如有需要，我可以分享。在此之後，通過數據網格發生的事件轉變：
<DataGrid Name="dtgResults" Background="Transparent" CanUserSortColumns="False" IsReadOnly="True" Foreground="Black" LoadingRow="Datagrid_LoadingRow">
<DataGrid.Resources>
<Style TargetType="DataGridCell">
<EventSetter Event="DataGridCell.Loaded" Handler="DataGridCell_Load"/>
<Setter Property="Tag" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}}"/>
<Setter Property="HorizontalAlignment" Value="Right" />
</Style>
</DataGrid.Resources>
</DataGrid>
那就是：
在Datagrid_LoadingRow
int index = row.GetIndex();
if (obcMyDim[index].IsComment) <-----a matrix telling when it's a comment
row.Foreground = new SolidColorBrush(Colors.White);
else
row.Foreground = new SolidColorBrush(Colors.Black);
所以它只是一個色素無電池數據的變化！
在DataGridCell_Load
，而不是I格式的小數位數，並通過這樣的：
DataGridCell cell = sender as DataGridCell;
DataGrid parentDataGrid = (DataGrid)(cell.Tag);
int column = cell.Column.DisplayIndex;// da 0
int row = -1;
//I get the line
DependencyObject rowDO = cell as DependencyObject;
while (rowDO != null && !(rowDO is DataGridRow))
rowDO = VisualTreeHelper.GetParent(rowDO);
if (rowDO != null)
{
DataGridRow gridrow = (DataGridRow)rowDO;
row = gridrow.GetIndex();
}
...
string strCellContent = ((TextBlock)cell.Content).Text;
if (strCellContent.Trim() != string.Empty)
{
if (strCellContent.IsNumeric())<----custom function
{
dVal = double.Parse(strCellContent, CultureInfo.InvariantCulture);
((TextBlock)cell.Content).Text = dVal.ToString("0.0000");
bool condOutOfTolerance = ...;
//Errore
if (column >= 5 && condOutOfTolerance)
cell.Foreground = new SolidColorBrush(Colors.Red);
}
}
因此，在短期的問題是，第一行的行爲古怪
這是第一張正確的圖像。 
後，然後有滾動向上/向下 DataGrid中的第一行改變
，然後再以不同
我得到那個不知何故它的感覺一個刷新的問題，但我不明白如何解決這個問題。
感謝您的幫助

下面是我手工填充我的DataGrid：

再次感謝您幫助！ ！
其他行上的值也在移動（其中一些改變了？） – stuartd
OMG我沒有注意到它!!!!!是的，我可以注意到所有價值線的上移...... – Patrick
