绑定到datagridview

Question

How can i bind data to datagridview?

DataTable table = new DataTable();
string pot = "Provider=Microsoft.Ace.OLEDB.12.0; Data Source = " + textbox_path.Text + ";Extended Properties=\"Excel 8.0; HDR=Yes;\";";
OleDbConnection pove = new OleDbConnection(pot);
OleDbDataAdapter myDataAdapter = new OleDbDataAdapter("Select * from [" + textbox_sheet.Text + "$]", pove);
DataTable dt = new DataTable();
myDataAdapter.Fill(dt); /* napaka | oldedb driver ? :O*/
dataGridView1.DataSource = dt;

Answer 1

在末尾添加：-

dataGridView1.DataBind();

Answer 2

If you are working in web application you have to add dataGridView1.DataBind(); after dataGridView1.DataSource = dt; .

Else tell us what is the problem in your above code? Is it throwing any error?

Answer 3

Check the below MSDN link. It has working examples.

Answer 4

Although you did not mention it, this question was tagged as winforms. Winforms does not need
dataGridView1.DataBind();
You have not given us any errors or hints as to where it fails. I suspect it is in the formation of this connection string or select statement. The code to bind the datatable to the DGV is correct

string pot = "Provider=Microsoft.Ace.OLEDB.12.0; Data Source = " + textbox_path.Text + ";Extended Properties=\"Excel 8.0; HDR=Yes;\";";
OleDbConnection pove = new OleDbConnection(pot);
OleDbDataAdapter myDataAdapter = new OleDbDataAdapter("Select * from [" + textbox_sheet.Text + "$]", pove);
