可能重复:
WPF DataGrid: How do you iterate in a DataGrid to get rows and columns?
我有WPF
DataGrid
。我想迭代cells
中的所有Datagrid
。
给我一个简单的代码来做到这一点。
喜欢这个
for(int i =0 ....) //rows
{
for(int j=0 ....) //columns
{
//access cell
}
}
答案 0 :(得分:3)
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;
}
}
//假设网格绑定到某些信息类的可观察集合
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
}
}
