winform 实现客户要求的在 DataGridView 自定义选择显示的列

[guangtoujiabaoji]

通过一个 CheckedListBox 实现，在 CheckedListBox 选中想要显示的列即可，代码如下：

private void Form1_Load(object sender, EventArgs e)
{
    SBKHSBYQ(dataGridView1, checkedListBox1);
}

public static void SBKHSBYQ(DataGridView D, CheckedListBox C)
{
    Dictionary<string, string> temps = new Dictionary<string, string>();
    foreach (DataGridViewColumn item in D.Columns)
    {
        C.Items.Add(item.HeaderText);
        temps[item.HeaderText] = item.Name;              
        C.SetItemChecked(item.Index, item.Visible);                             
    }
    C.ItemCheck += (o, e) =>
    {
        if(e.NewValue==CheckState.Unchecked)
            D.Columns[temps[(o as CheckedListBox).SelectedItem.ToString()]].Visible=false;
        else if(e.NewValue==CheckState.Checked)
            D.Columns[temps[(o as CheckedListBox).SelectedItem.ToString()]].Visible = true;
    };
}
