How to copy DataGrid cell value to clipboard
提问by Farhad Jabiyev
I have a DataGrid. But I want to get focused cell value in CopyingRowClipboardContentevent. But e.ClipboardRowContentreturns me all selected cells values because of the SelectionUnit. And i must not change selection unit of datagrid. For solving the problem i need to get focused cell column number. Then I will remove all column values from clipboarcContent.
How can i get focused cell in CopyingRowClipboardContentevent?

I find the solution. First of all I have needed column number of the focused cell. I have managed to get it with this code:
我找到了解决办法。首先，我需要聚焦单元格的列号。我设法用这个代码得到它：
DataGridResults.CurrentCell.Column.DisplayIndex;
Then in CopyingRowClipboardContentevent, I must delete all other column values.
然后CopyingRowClipboardContent，我必须删除所有其他列值。
private void DataGridResults_CopyingRowClipboardContent(object sender, DataGridRowClipboardEventArgs e)
{
int y = 0;
for (int i = 0; i < e.EndColumnDisplayIndex; i++)
{
if (i != DataGridResults.CurrentCell.Column.DisplayIndex)
{
e.ClipboardRowContent.RemoveAt(i - y);
y++;
}
}
}

I found that this solution worked for me on all DataGrids; even ones that had hidden columns.
我发现这个解决方案适用于所有 DataGrids；甚至那些有隐藏列的。
// Clipboard Row content only includes entries for visible cells
// Figure out the actual column we are looking for (taking into account hidden columns)
int columnIndex = dataGrid.CurrentCell.Column.DisplayIndex;
var column = dataGrid.Columns[columnIndex];
// Find the associated column we're interested in from the clipboard row content
var cellContent = clipboardRowContent.Where(item => item.Column == column).First();
clipboardRowContent.Clear();
clipboardRowContent.Add(cellContent);
