Question

This is the code i’m using in my project:

private void button1_Click(object sender, EventArgs e)
    {
        OleDbConnection conn = new OleDbConnection();
        conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\KursniListi.xlsx" + @";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1;ImportMixedTypes=Text;TypeGuessRows=0""";

        OleDbCommand command = new OleDbCommand
        (
            "SELECT *" +
            "FROM [Sheet1$]", conn
        );

        DataSet dsKL = new DataSet();
        OleDbDataAdapter adapter = new OleDbDataAdapter(command);
        adapter.Fill(dsKL);

        dataGridView1.DataSource = dsKL.Tables[0];

    }

I need this to display me: rows 1 and 11, columns C,E,F

Answer 1

You can hide columns and rows on your datagrid using the Visible property

this.dataGridView1.Columns[0].Visible = false;
....

this.dataGridView1.Rows[1].Visible = false;
....

(I have used the index for the columns/rows because I can’t type your header names)
However without knowing the requirement to hide rows it’s difficult to give a satisfying answer.
