How to populate datagrid from datatable?

Question

C++ / C#

there is a datagrid where 2 columns of the required size are created and there is a datatable where I add row. when I write datagridview.datasource= dt; new columns appear on the right and are not added to those that exist, how to fix it?

the code

DataColumn name = new DataColumn("Названия", typeof(string));
           DataColumn data = new DataColumn("Значения", typeof(string));
            dt.Columns.AddRange(new DataColumn[] { name, data });

           

            DataRow row1 = dt.NewRow();
            row1[0] = "прибор";
            row1[1] = "212211";

            dt.Rows.Add(row1);

Answer 1

Delete your columns
In the code, then set up the display, like:

dataGridView1.Columns[0].HeaderText = "№";
dataGridView1.Columns[0].MinimumWidth = 25;
dataGridView1.Columns[0].Width = 40;
dataGridView1.Columns[0].Visible = true;

dataGridView1.Columns[1].HeaderText = "Спрятанная колонка";
dataGridView1.Columns[1].Visible = false;
