求教一点技巧
有一个包含2个页面tabControl控件,每个页面放一个datagridview控件,采用默认名datagridview1和datagridview2
如果要设计一个绑定函数来控制datagrideview列的显示,通过参数i来控制到底是哪个datagridview

C# code

                private void mainform_Load(object sender, EventArgs e)        {            bindgrid(1) //显示datagridview1列             bindgrid(2) //显示datagridview2列        }        private void bindgrid(int i)        {   dataGridView1.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells);            DataGridViewTextBoxColumn col_prog = new DataGridViewTextBoxColumn();            col_prog.DataPropertyName = "program";            col_prog.HeaderText = "栏目";            col_prog.Name = "program";            col_prog.ReadOnly = true;            col_prog.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;            dataGridView1.Columns.Add(col_prog);        }
