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 = ; i < ; 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 = ;
dataGridView1.ColumnHeadersVisible = true; // Set the column header style.
DataGridViewCellStyle columnHeaderStyle = new DataGridViewCellStyle(); columnHeaderStyle.BackColor = Color.Beige;
columnHeaderStyle.Font = new Font("Verdana", , FontStyle.Bold);
dataGridView1.ColumnHeadersDefaultCellStyle = columnHeaderStyle; // Set the column header names.
dataGridView1.Columns[].Name = "Recipe";
dataGridView1.Columns[].Name = "Category";
dataGridView1.Columns[].Name = "Main Ingredients";
dataGridView1.Columns[].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(, column);
DGV的常用属性设置
1. 禁用编辑功能
dataGridView1.ReadOnly = true ;
2.不让DataGridView自动生成列
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;
