对于WinForms,它是：
var value = DataGridView.Rows[0].Cells[0].Value
有没有办法在WPF中获取它？
解决方法
我认为最好的方法是使用Items属性并直接访问您的数据项：
var dataItem = dataGrid.Items[0] as ...;
但是您可以使用此类来获取单元格并使用GetValue()方法访问该值(更像您的示例).
代码取自此处：datagrid get cell index
static class DataGridHelper {
static public DataGridCell GetCell(DataGrid dg,int row,int column) {
DataGridRow rowContainer = GetRow(dg,row);
if (rowContainer != null) {
DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(rowContainer);
// try to get the cell but it may possibly be virtualized
DataGridCell cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
if (cell == null) {
// now try to bring into view and retreive the cell
dg.ScrollIntoView(rowContainer,dg.Columns[column]);
cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
}
return cell;
}
return null;
}
static public DataGridRow GetRow(DataGrid dg,int index) {
DataGridRow row = (DataGridRow)dg.ItemContainerGenerator.ContainerFromIndex(index);
if (row == null) {
// may be virtualized,bring into view and try again
dg.ScrollIntoView(dg.Items[index]);
row = (DataGridRow)dg.ItemContainerGenerator.ContainerFromIndex(index);
}
return row;
}
static T GetVisualChild<T>(Visual parent) where T : Visual {
T child = default(T);
int numVisuals = VisualTreeHelper.GetChildrenCount(parent);
for (int i = 0; i < numVisuals; i++) {
Visual v = (Visual)VisualTreeHelper.GetChild(parent,i);
child = v as T;
if (child == null) {
child = GetVisualChild<T>(v);
}
if (child != null) {
break;
}
}
return child;
}
}
