Winform DataBinding

Question

我需要启用/禁用datagridview的行列，这可以通过在绑定后循环所有行来轻松完成。 但我想在数据绑定时这样做...有没有办法做到这一点？我如何启用/禁用行单元格？

dgvLayout.AutoGenerateColumns = false;
dgvLayout.DataSource = list;

单击单击

但它不起作用

if ((dgvLayout.Rows[e.RowIndex].Cells["colControlText"].Value.ToString()) == "-Invalid-")
{
    if (e.ColumnIndex == 2 || e.ColumnIndex == 5)
    {
        return;
    }
    else if (e.ColumnIndex == 1)
    {
        return;
    }
}

Answer 1

您可以在datagrid的RowsAdded事件上编写代码

Answer 2

您可以使用此解决方案启用和禁用单元格

要“禁用”一个单元格，它必须是只读的并以某种方式变灰。此函数启用/禁用DataGridViewCell：

    /// <summary>
    /// Toggles the "enabled" status of a cell in a DataGridView. There is no native
    /// support for disabling a cell, hence the need for this method. The disabled state
    /// means that the cell is read-only and grayed out.
    /// </summary>
    /// <param name="dc">Cell to enable/disable</param>
    /// <param name="enabled">Whether the cell is enabled or disabled</param>
    private void enableCell(DataGridViewCell dc, bool enabled) {
        //toggle read-only state
        dc.ReadOnly = !enabled;
        if (enabled)
        {
            //restore cell style to the default value
            dc.Style.BackColor = dc.OwningColumn.DefaultCellStyle.BackColor;
            dc.Style.ForeColor = dc.OwningColumn.DefaultCellStyle.ForeColor;
        }
        else { 
            //gray out the cell
            dc.Style.BackColor = Color.LightGray;
            dc.Style.ForeColor = Color.DarkGray;
        }
    }
