Winform DataBinding

Question

我需要啓用/禁用datagridview的行列，這可以通過在綁定所有行後進行循環來輕鬆完成。 但我想這樣做，而數據綁定...有沒有辦法做到這一點？也如何啓用/禁用行單元格？

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

細胞點擊

，但它不工作

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

您可以使用此解決方案的啓用和禁用電池

要「禁用」一個單元格，它必須是隻讀的，並以某種方式變爲灰色。此功能啓用/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; 
     } 
    }

你可以在數據網格的RowsAdded事件給你寫代碼
