顯示、隱藏DataGridView的列

原創 a313976010 2020-02-24 14:41

最近閒來無事，就做了個自定義顯示隱藏DataGridView列的控件。如下圖，左邊是隱藏字段，右邊是顯示的字段，可以上下排序、置頂置底，保存之後DataGridView會按照以選擇的字段順序調整列的先後順序。雙擊字段可以移除到列一個列表中去，可以相互拖拽等功能，右鍵菜單有全選、取消等操作。就是上下排序的時候不能實現多選，希望各位大神看看能不能幫我解決一下這個問題，在此謝過了。好了，廢話不多說了，代碼貼上：

2011-09-05 升級說明：增加顯示字段的保存。以選字段會保存下來，關閉後下次在打開DataGridView會按照您上次的排序及算則的字段進行排序

調用方法如下：

private void 顯示字段ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (dataGridView1.RowCount > 0)
