获取数据网格中的所有单元格

问题描述

是否有一种方法可以获取DataGrid中所有单元的可迭代集合，而不管是否已选中它们

Is there a way to get an iteratable collection of all the cells in a DataGrid regardless of whether they are selected or not

推荐答案

如果您的意思是 DataGridCell s，则可以使用Vincent Sibals帮助函数遍历 DataGrid.Items 的所有行和列 DataGrid.Columns 。

If you mean DataGridCells you could use Vincent Sibals helper functions to iterate over all rows DataGrid.Items and columns DataGrid.Columns.

public DataGridCell GetCell(int row, int column)
{
    DataGridRow rowContainer = GetRow(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_Standard.ScrollIntoView(rowContainer, DataGrid_Standard.Columns[column]);
            cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
        }
        return cell;
    }
    return null;
}

public DataGridRow GetRow(int index)
{
    DataGridRow row = (DataGridRow)DataGrid_Standard.ItemContainerGenerator.ContainerFromIndex(index);
    if (row == null)
    {
        // may be virtualized, bring into view and try again
        DataGrid_Standard.ScrollIntoView(DataGrid_Standard.Items[index]);
        row = (DataGridRow)DataGrid_Standard.ItemContainerGenerator.ContainerFromIndex(index);
    }
    return row;
}

如果网格是您的DataGrid，则将获得所有DataGridCell的列表，如下所示：

If grid is your DataGrid you get a list of all DataGridCells like this:

List<DataGridCell> allCellList = new List<DataGridCell>();

for (int i = 0; i < grid.Items.Count; i++)
{
    for (int j = 0; j < grid.Columns.Count; j++)
    {
        allCellList.Add(grid.GetCell(i, j));
    }
}
