我有一个 DataGrid WPF 控件,我想获得一个特定的 DataGridCell.我知道行和列索引.我该怎么做?
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 DataGridCell 因为我必须访问它的内容.因此,如果我有(例如)一列 DataGridTextColum,我的内容将是一个 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.
推荐答案你可以使用类似这样的代码来选择一个单元格:
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;我看不到直接更新特定单元格内容的方法,因此为了更新特定单元格的内容,我将执行以下操作
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.更多推荐
从 DataGrid 中选择 DataGridCell
