Question

好的，所以我有这段代码，我尝试将所有行设置为只读一些。

由于条件每行更改，我将所有单元格设置为ReadOnly，然后解锁我需要的单元格。

没有涉及数据绑定。我使用网格＆＃34;按原样＃34;。

cells [1]是DataGridViewTextBoxCell

cells [4]是DataGridViewComboBoxCell

当我这样做时：

row.ReadOnly = true;
row.Cells[1].ReadOnly = false; //Successfully changes from true to false.
row.Cells[4].ReadOnly = false; // This DOES NOT work!

好的，所以我尝试了别的东西：

foreach (DataGridViewCell cell in row.Cells)
{
    cell.ReadOnly = true; //Successfully changes from false to true.
}
row.Cells[1].ReadOnly = false; // This DOES NOT work!
row.Cells[4].ReadOnly = false; // This DOES NOT work!

这里是列定义：

textBoxColumn = new DataGridViewTextBoxColumn();
textBoxColumn.Name = "Column0";
textBoxColumn.HeaderText = "My column header";
textBoxColumn.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
textextBoxColumn.Resizable = DataGridViewTriState.True;
textextBoxColumn.SortMode = DataGridViewColumnSortMode.NotSortable;
dataGridView.Columns.Add(textBoxColumn);

comboBoxBoxColumn = new DataGridViewComboBoxColumn();
comboBoxBoxColumn.Name = "Column4";
comboBoxBoxColumn.HeaderText = "My column header";
comboBoxBoxColumn.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
comboBoxBoxColumn.Resizable = DataGridViewTriState.True;
comboBoxBoxColumn.Items.Add("Item 1");
comboBoxBoxColumn.Items.Add("Item 2");
comboBoxBoxColumn.SortMode = DataGridViewColumnSortMode.NotSortable;
dataGridView.Columns.Add(comboBoxBoxColumn);

我只是不明白。

修改：

这是我创建行的方式：我首先创建所有（数百个）行，然后将其一次性添加到DataGridView中，以避免UI刷新：

row = new DataGridViewRow();
for (Int32 i = 0; i < dataGridView.Columns.Count; i++)
{
    DataGridViewCell cell;
    DataGridViewColumn column;

    column = dataGridView.Columns[i];
    cell = (DataGridViewCell)(column.CellTemplate.Clone());
    row.Cells.Add(cell);
}

DataGridViewCell.ReadOnly = false不起作用
