如何在WPF網格中獲取選定的列名或索引

Question

您能告訴我如何在WPF網格中獲取選定的列名或索引嗎？

Answer 1

對於DataGrid，可以通過CurrentCell屬性獲得該列：

DataGridCellInfo cellInfo = dataGrid.CurrentCell;
DataGridColumn column=cellInfo.Column;

Answer 2

嘗試此操作以獲取所選行的列表：

IList rows = dg.SelectedItems;

從這個相關的問題 。

Answer 3

這就是我們如何獲取特定單元格的值

Object obj = GetCell(3).Content;
                     string cellContent = String.Empty;
                     if (obj != null)
                     {
                         if (obj is TextBox)
                             cellContent = ((TextBox)(obj)).Text;
                         else
                             cellContent = ((TextBlock)(obj)).Text;
                      }




private DataGridCell GetCell(int column)
    {
        DataGridRow rowContainer = GetRow();

        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.
                customDataGrid.UCdataGridView.ScrollIntoView(rowContainer, customDataGrid.UCdataGridView.Columns[column]);
                cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
            }
            return cell;
        }
        return null;
    }
