如何获取WPF Grid中的选定列名称或索引

Question

您可以告诉您如何获取WPF Grid中的选定列名称或索引。

Answer 1

这是我们可以得到一个特定的细胞

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; 
    }

对于DataGrid，您可以通过CurrentCell属性得到列：

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