在WPF数据网格的代码背后,如何从我的dataGrid.SelectedItem(在代码中)中获取currentCell?
非常感谢,
解决方法:
从post开始尝试
您可以通过dataGrid.CurrentColumn.DisplayIndex从dataGrid.SelectedIndex和column中检索行.
public static DataGridCell GetCell(DataGrid dataGrid, int row, int column)
{
DataGridRow rowContainer = GetRow(dataGrid, 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
dataGrid.ScrollIntoView(rowContainer, dataGrid.Columns[column]);
cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
}
return cell;
}
return null;
}
编辑
public static DataGridRow GetRow(DataGrid dataGrid, int index)
{
DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(index);
if (row == null)
{
dataGrid.ScrollIntoView(dataGrid.Items[index]);
dataGrid.UpdateLayout();
row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(index);
}
return row;
}
