WPF DataGrid: How do you iterate in a DataGrid to get rows and columns?

所有單元格我有一個WPFDataGrid。我想遍歷Datagrid中的所有cells。 給我一個簡單的代碼來做到這一點。 像這樣

for(int i =0 ....) //rows 
{ 
    for(int j=0 ....) //columns 
    { 
     //access cell 
    } 
} 

Answer 1

public IEnumerable<Microsoft.Windows.Controls.DataGridRow> GetDataGridRows(Microsoft.Windows.Controls.DataGrid grid) 
{ 
    var itemsSource = grid.ItemsSource as IEnumerable; 
    if (null == itemsSource) yield return null; 
    foreach (var item in itemsSource) 
    { 
     var row = grid.ItemContainerGenerator.ContainerFromItem(item) as Microsoft.Windows.Controls.DataGridRow; 
       if (null != row) yield return row; 
     } 
} 

//假設網格綁定到一些信息類

foreach (DataGridRow rowContainer in GetDataGridRows(gridname)) 
{ 
    if (rowContainer != null) 
    { 
    DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(rowContainer); 

    DataGridCell cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column); 
    if (cell == null) 
    { 
     dataGrid1.ScrollIntoView(rowContainer, dataGrid1.Columns[column]); 
     cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column); 
     } 

     //start work with cell 
    } 
}
