1.ContextMenuStrip 获取右键控件名称

this.contextMenuScriptScore.SourceControl.Name; //当前控件名

2.radiobutton 分组

放入一个Panel里面。

例如，放入一直flowLayoutPanel里

3.动态生成一个Label,放入flowLayoutPanel里。

 private void AddLable(int number, string text )

        {

            Label lable = new Label();

            lable.Name = "lab_tgt_word_" + number;

            lable.Text = text;

            lable.AutoSize = true;

            lable.BorderStyle = BorderStyle.FixedSingle;

            lable.Size = new Size(50, 50);

            lable.Margin = new Padding(0, 0, 10, 20);

            lable.Location = new Point(this.flowLayoutPanel2.Size);

            lable.ContextMenuStrip = contextMenuScriptScore;        //右键菜单

            this.flowLayoutPanel2.Controls.Add(lable);

        }

4.用户控件(userControl)刷新父窗体的datagridview

//2.userControl刷新父窗体 datagridview

var mainForm = (Main)this.Parent;

DataTable table = (DataTable)mainForm.dataGridView1.DataSource;

table.Rows[tableJson.ID - 1]["tgt_len_compute"] = tableJson.TgtLenCompute.ToString();

mainForm.dataGridView1.DataSource = table;

5.datagridview导出excel，去掉一列，不改变datagridview

DataGridView dgv = this.dataGridView1;

DataTable dataTable = (DataTable)dgv.DataSource;

//必须copy，才不会改变datagridview的绑定源

DataTable datatableCopy = dataTable.Copy();

datatableCopy.Columns.Remove("ID");

 string sheetName = datatableCopy.Rows[0][0].ToString().ToUpper() + "&" + datatableCopy.Rows[0][1].ToString().ToUpper();

                ExcelHelper.ExportToExcel(datatableCopy, sheetName, saveFileDialog1.FileName);

 ExcelHelper.ExportToExcel(datatableCopy, sheetName, saveFileDialog1.FileName);

6.自定义MessageBox 按钮的文本

使用

DialogResult dialog = MessageBoxEx.Show("does it load directly or does it recalculate?", "hint", MessageBoxButtons.YesNo, new String[] { "load", "recalculate" });

代码

using System;

using System.Drawing;

using System.Runtime.InteropServices;

using System.Text;

using System.Windows.Forms;

namespace Sphinx.Utils

{

    public class MessageBoxEx

    {

        public static DialogResult Show(string text, string caption, MessageBoxButtons buttons, string[] buttonTitles)

            frm.Show();

            frm.WatchForActivate = true;

            DialogResult result = MessageBox.Show(frm, text, caption, buttons);

            frm.Close();

            return result;

        }

            frm.Close();

            return result;
