动态添加列和行
方法一
通过手动添加Datatable,再绑定dataGridView
DataTable dt = new DataTable();//建立个数据表 dt.Columns.Add(new DataColumn("id", typeof(int)));//在表中添加int类型的列 dt.Columns.Add(new DataColumn("Name", typeof(string)));//在表中添加string类型的Name列 DataRow dr;//行 for (int i = 0; i < 3; i++) { dr = dt.NewRow(); dr["id"] = i; dr["Name"] = "Name" + i; dt.Rows.Add(dr);//在表的对象的行里添加此行 } dataGridView1.DataSource =dt;
如果要添加一个textbox效果的列,可做如下处理
dt.Columns.Add(new DataColumn("选中", typeof(bool));
方法二
直接在dataGridView中插入
dataGridView1.ColumnCount = 4; dataGridView1.ColumnHeadersVisible = true; // Set the column header style. DataGridViewCellStyle columnHeaderStyle = new DataGridViewCellStyle(); columnHeaderStyle.BackColor = Color.Beige; columnHeaderStyle.Font = new Font("Verdana", 10, FontStyle.Bold); dataGridView1.ColumnHeadersDefaultCellStyle = columnHeaderStyle; // Set the column header names. dataGridView1.Columns[0].Name = "Recipe"; dataGridView1.Columns[1].Name = "Category"; dataGridView1.Columns[2].Name = "Main Ingredients"; dataGridView1.Columns[3].Name = "Rating"; // Populate the rows. string[] row1 = new string[] { "Meatloaf", "Main Dish", "ground beef","**" }; string[] row2 = new string[] { "Key Lime Pie", "Dessert", "lime juice, evaporated milk", "****" }; string[] row3 = new string[] { "Orange-Salsa Pork Chops", "Main Dish", "pork chops, salsa, orange juice", "****" }; string[] row4 = new string[] { "Black Bean and Rice Salad", "Salad", "black beans, brown rice", "****" }; string[] row5 = new string[] { "Chocolate Cheesecake", "Dessert", "cream cheese", "***" }; string[] row6 = new string[] { "Black Bean Dip", "Appetizer", "black beans, sour cream", "***" }; object[] rows = new object[] { row1, row2, row3, row4, row5, row6 }; foreach (string[] rowArray in rows) { dataGridView1.Rows.Add(rowArray); }
插入DataGridViewCheckBoxColumn列
DataGridViewCheckBoxColumn column = new DataGridViewCheckBoxColumn(); { column.HeaderText = "选中"; column.Name = isSelected; column.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells; column.FlatStyle = FlatStyle.Standard; column.ThreeState = true; column.CellTemplate = new DataGridViewCheckBoxCell(); column.CellTemplate.Style.BackColor = Color.Beige; }
DataGridView1.Columns.Insert(0, column);
DGV的常用属性设置
1. 禁用编辑功能
dataGridView1.ReadOnly = true ;
只需要把属性AutoGenerateColumns设为false即可。
需要注意: 在界面设计的属性窗口中是看不到AutoGenerateColumns属性的,
需要在代码中设定,比如在窗口的构造函数中设定:dataGridView1.AutoGenerateColumns = false;
没有整理与归纳的知识,一文不值!高度概括与梳理的知识,才是自己真正的知识与技能。 永远不要让自己的自由、好奇、充满创造力的想法被现实的框架所束缚,让创造力自由成长吧! 多花时间,关心他(她)人,正如别人所关心你的。理想的腾飞与实现,没有别人的支持与帮助,是万万不能的。
