GridDataView实现 点击任意一格可以修改

直接上代码好了

private void dgv1Member_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{

string name = this.dgv1Member.Columns[this.dgv1Member.CurrentCell.ColumnIndex].HeaderText;
this.dgv1Member.BeginEdit(true);//将单元格设为编辑状态
if (name == "会员号")
{
this.dgv1Member.Rows[e.RowIndex].Cells[e.ColumnIndex].ReadOnly = true;//将当前单元格设为可读
MessageBox.Show("会员名唯一，不允许修改");
}
else
{
this.dgv1Member.Rows[e.RowIndex].Cells[e.ColumnIndex].ReadOnly = false;//将当前单元格设为可读
}

string MemberID = this.dgv1Member.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();//获取当前单元格MemberID
}

private void dgv1Member_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
string aa = dgv1Member.Columns[this.dgv1Member.CurrentCell.ColumnIndex].DataPropertyName;//Name
string aa1 = dgv1Member.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();//真真
string aa2 = dgv1Member.Columns[0].DataPropertyName;//Memeerid
string aa3 = dgv1Member.Rows[e.RowIndex].Cells[0].Value.ToString();//id=6

string sql = String.Format("update Member set {0} = '{1}' where {2} ='{3}'",
dgv1Member.Columns[this.dgv1Member.CurrentCell.ColumnIndex].DataPropertyName, //所选单元格列名
dgv1Member.Rows[e.RowIndex].Cells[e.ColumnIndex].Value, //所选单元格修改
dgv1Member.Columns[0].DataPropertyName, //所选单元格列名
dgv1Member.Rows[e.RowIndex].Cells[0].Value); //所选行的商品

SqlConnection con = new SqlConnection();
con.ConnectionString = "Data Source=.;Initial CataLog=xiyidian;integrated security=true";
con.Open();
SqlCommand com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.Text;
com.CommandText = sql;
SqlDataReader dr = com.ExecuteReader();
dr.Close();
con.Close();

GridViewDataBind();

}
