1.需要安装EPPlus插件2.引入usingOfficeOpenXml;usingOfficeOpenXml.Style; 3.代码publicvoidExportDataGridViewToExcel(DataGridViewdgv,stringfilePath)    {      //设置EPPlus的许可证上下文      ExcelPackage.Licens

C#WinformDataGridView头部行高自动适应文本//头部行高自动适应DGV.ColumnWidthChanged+=DGV_ColumnWidthChanged;///<summary>///DataGridView头部行高自动适应文本///</summary>///<paramna

效果图： 在此之前感谢博主，winform无法屏蔽回车事件、KeyPress事件不执行问题解决-CSDN博客根据该大佬的方式，需处理添加回车事件处理，便继承了RichTextBox重写该方法，且执行了执行事件publicsealedclassMyUIRichTextBox:UIRichTextBox{publicboolLastRow=false;

1、场景需求，勾选单元格，获取所有当权选中数据；先用第一个单元格修改事件，privatevoiddgvMain_CellEndEdit(objectsender,DataGridViewCellEventArgse){}发现勾选完，光标移走才触发； 实现方法，两个事件；初始化列增加FalseValue=0,TrueValue=1,

 //nuget导入npoi我就不说了。。。 privatevoidbutton1_Click(objectsender,EventArgse){//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++//交互->不需要拖入控件stringstrFileName="";

第一种风格：1///<summary>2///第一种样式3///</summary>4publicvoidDgvStyle1(DataGridViewdgv)5{6//奇数行的背景色7dgv.AlternatingRowsDefaultCellStyle.BackColor=S

//在DataGridView的PreviewKeyDown事件中privatevoiddataGridView1_PreviewKeyDown(objectsender,PreviewKeyDownEventArgse){if(e.Control&&e.KeyCode==Keys.V)//判断是否按下ctrl+v{Paste(dataGridView1,"",0,false);//粘贴代码}}粘贴，行数和列数不

privatevoiddataGridView_RowPostPaint(objectsender,DataGridViewRowPostPaintEventArgse){try{DataGridVie

privatevoiddgv_RowPrePaint(objectsender,DataGridViewRowPrePaintEventArgse){if(infos[e.RowIndex].HaveDetails=="不存在")//此条

privatevoidGetDGVData(){dataGridView1=DynamicCreationDGV(dataGridView1);}privateDataGridViewDynamicCreationDGV

1:场景：由于环境需要，在获取数据源的时候会获取多于DataGridView中绑定的字段，若不做任何处理，直接将数据源绑定到DataGridView上面，DataGridView就会将数据源中没有绑定的字段
