c# - 鼠标右键选择单元格

Question

如何通过鼠标右键单击 RadGridView 中的单元格？

以下代码不起作用：

private void RadGridView_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    // ... getting grid and cell
    if (e.RightButton == MouseButtonState.Pressed)
    {
        grid.UnselectAll();
        grid.CurrentCellInfo = new GridViewCellInfo(cell);
        cell.IsCurrent = true;
        cell.IsSelected = true;
    }
}

这很奇怪，但选择行工作正常：

if (e.RightButton == MouseButtonState.Pressed)
{
    grid.UnselectAll();
    row.IsSelected = true;
    row.IsCurrent = true;
}

Answer 1

if (e.RightButton == MouseButtonState.Pressed)
{
    grid.Focus();
    grid.UnselectAll();
    grid.CurrentCellInfo = new GridViewCellInfo(cell);
    grid.SelectedCells.Add(grid.CurrentCellInfo);
}

Answer 2

你试过 grid.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect 吗？

使用 OriginalSource 获取被点击的单元格（记住它也可以为空）并设置 IsSelected 值。
