从DataGrid中选择DataGridCell [英] Select DataGridCell from DataGrid
问题描述
我有一个的DataGrid
WPF控件,我希望得到一个特定的 DataGridCell
。我所知道的行和列索引。我怎样才能做到这一点?
I have a DataGrid
WPF control and I want to get a specific DataGridCell
. I know the row and column indices. How can I do this?
我需要的 DataGridCell
,因为我要访问它的内容。所以,如果我有(例如) DataGridTextColum
的专栏,我的内容将是一个的TextBlock
对象。
I need the DataGridCell
because I have to have access to its Content. So if I have (for example) a column of DataGridTextColum
, my Content will be a TextBlock
object.
推荐答案
您可以用code与此类似,选择一个单元格:
You can use code similar to this to select a cell:
var dataGridCellInfo = new DataGridCellInfo(
dataGrid.Items[rowNo], dataGrid.Columns[colNo]);
dataGrid.SelectedCells.Clear();
dataGrid.SelectedCells.Add(dataGridCellInfo);
dataGrid.CurrentCell = dataGridCellInfo;
我看不到一个办法直接更新特定单元格的内容,所以为了更新特定的细胞,我会做如下的内容
I can't see a way to update the contents of a specific cell directly, so in order to update the content of a specific cell I would do the following
// gets the data item bound to the row that contains the current cell
// and casts to your data type.
var item = dataGrid.CurrentItem as MyDataItem;
if(item != null){
// update the property on your item associated with column 'n'
item.MyProperty = "new value";
}
// assuming your data item implements INotifyPropertyChanged the cell will be updated.
