Hi!

I want to import specific cells of an Excel file to specific cells of a datagridview.

I followed many tutorials here that import Excel tables, but as I want only specific cells in specific locations of the datagridview, I adapted the code.

Instead of: DataGridView1.DataSource = dt; I did: dataGridView1.Rows[0].Cells[0].Value = dt; but it doesn’t work.

Can anyboby help me please?

Thank you.


Here is the code:

C#
string constr = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + textBox1.Text + @";Extended Properties=""Excel 12.0 Macro;HDR=YES;ImportMixedTypes=Text;TypeGuessRows=0""";

           OleDbConnection con = new OleDbConnection(constr);

           //specific cell 1 - product "code"
           OleDbDataAdapter sda = new OleDbDataAdapter("Select * From [ARTIGOS$A" + textBox3.Text + ":A" + textBox3.Text + "]", con);
           //specific cell 2 - product "description"
           OleDbDataAdapter sdb = new OleDbDataAdapter("select * From [ARTIGOS$B" + textBox3.Text + ":B" + textBox3.Text + "]", con);
           //specific cell 3 - product "price"
           OleDbDataAdapter sdc = new OleDbDataAdapter("Select * From [ARTIGOS$I" + textBox3.Text + ":I" + textBox3.Text + "]", con);

           DataTable dt = new DataTable();
           DataTable dt2 = new DataTable();
           DataTable dt3 = new DataTable();

           sda.Fill(dt);
           sdb.Fill(dt2);
           sdc.Fill(dt3);

           dataGridView1.Rows.Add();
           dataGridView1.Rows[0].Cells[0].Value = dt;
           dataGridView1.Rows[0].Cells[1].Value = dt2;
           dataGridView1.Rows.Add();
           dataGridView1.Rows[0].Cells[2].Value = textBox2.Text;
           dataGridView1.Rows[0].Cells[3].Value = dt3;

You can't add a datatable object into a value inside a cell.
You can bind a datatable into dataGridView.DataSource property.

Using OleDb it's not possible!

Steps to do:
1) Create new instance of MS Excel
2) Open workbook
3) Get data from worksheet and insert into DataGridView
4) Close workbok
5) Close application

Hi Maciej, why it is not possible doing it using OleDb?

OleDb driver provides methods to read tabular format data. As i see, you want to read specific Excel ranges: A...:A..., B...:B.... OleDb driver reads data in continuos way, usually UsedRange.

You can't set values like that: dataGridView1.Rows[0].Cells[1].Value = dt2;, because datatable object is a set of records.
BTW, dataGridView1 has DataSource property: dataGridView1.DataSource = dt2;
Please, read msdn documentation.

Thanks for the reply. OleDb gets the job done in the case presented by ricardo. On the subject of DataSource I did not understand, because my comment was exactly that.

I would consider Excel Interopt: http://www.dotnetperls.com/excel[^]
