Datagrid：如何获取SelectedCell的SelectedItem？ [英] Datagrid: How to get the CurrentCell of the SelectedItem?

问题描述

在WPF datagrid的代码中，如何从我的dataGrid.SelectedItem（In代码）中获取currentCell？

许多谢谢，

解决方案

请尝试从 post

您可以从 dataGrid.SelectedIndex 和列by dataGrid.CurrentColumn.DisplayIndex

  public static DataGridCell GetCell（DataGrid dataGrid，int row，int column）
 {
 DataGridRow rowContainer = GetRow（dataGrid，row）; 
 if（rowContainer！= null）
 {
 DataGridCellsPresenter Presenter = GetVisualChild< DataGridCellsPresenter>（rowContainer）; 
 
 //尝试获取单元格但可能会被虚拟化
 DataGridCell cell =（DataGridCell）presenter.ItemContainerGenerator.ContainerFromIndex（column）; 
 if（cell == null）
 {
 //现在尝试带入视图并检索单元格
 dataGrid.ScrollIntoView（rowContainer，dataGrid.Columns [column]）; 
 
 cell =（DataGridCell）presenter.ItemContainerGenerator.ContainerFromIndex（column）; 
} 
 
返回单元格; 
} 
 
返回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）; 
} 
 
返回行; 
}

Many Thanks,

Try this from post

You can retrieve row from dataGrid.SelectedIndex and column by dataGrid.CurrentColumn.DisplayIndex

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;
}

Edit

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;
    }
