Rename Column of DataGridView

I want to display a grid with the data from this sql query

SELECT * FROM invoices WHERE ddate >= curdate() - interval 180 day  AND equipment = 1 order by invoice_number desc

I think i have it working, however when i load the form in the program, I get an empty box.

I have attached the entire code

The columns i want are

invoice_number, ddate, company_name, and initials]

If possible, i would like the column names to be

Invoice Number, Date, Company Name and Initials

Just to make sure the connection works, i put a message box with the number of rows it found, and it returns the correct value.

I am just starting to learn vb.net so if the answer could explain as much as possible that would be a big help.

Public Class frmLookupInvoice
 
    Private Sub frmLookupInvoice_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim dt As New DataTable
        Dim dv As New DataView
        Dim SQL
 
        conn.ConnectionString = My.Settings.csInventory
 
        Try
            conn.Open()
            myCommand.Connection = conn
            SQL = "SELECT invoice_number, ddate, company_name, and initials FROM invoices WHERE ddate >= curdate() - interval 180 day  AND equipment = 1 order by invoice_number desc"
            myCommand.CommandText = SQL
            myAdapter.SelectCommand = myCommand
            myAdapter.Fill(dt)
            Dim numRows As Integer = dt.Rows.Count
 
            If (numRows) = 0 Then
                MessageBox.Show("No Invoices found")
            End If
 
            If (numRows) > 0 Then
 
                MessageBox.Show("Rows Found: " & dt.Rows.Count)
            End If
            conn.Close()
        Catch sqlerr As MySqlException
            MessageBox.Show(sqlerr.Message, "Error: " & sqlerr.Number)
 
            conn.Dispose()
        End Try
        'Dim invoice_number = dt.Rows(0)("access_level")
        myAdapter.GetFillParameters()
        'dt.Columns.Add(New DataColumn("Invoice Number", GetType(System.String), "invoice_number"))
        DataGridView1.DataSource = dv
 
 
 
 
 
 
 
 
    End Sub
 
    Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick

You can do this in the GridView's RowDataBound or RowCreated event. You just have to filter the RowType to make sure it's a Header.

The sample below is in C# if you don't mind.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

    if(e.Row.RowType == DataControlRowType.Header)

    {

        e.Row.Cells[0] = "Column Name";


    }


}

Why don't you change the query itself:

SQL = "SELECT invoice_number as [Invoice Number], ddate as [Date], company_name as [Company Name], and initials as [Initials] FROM invoices WHERE ddate >= curdate() - interval 180 day  AND equipment = 1 order by invoice_number desc"

I didn't know  you could do that


You don't have to answer this, I can make another question but, How do you make a simple repeating region.  See, I am used to web design using dreamweaver.  If i wanted a table full of data, I would just drag the items from the bindings panel, and slap on a repeating region, and it would display all the records.  I am trying to find a way of doing that here, and I just can't seem to figure out how

Actually, it's very simple with VB2005. Go to the "Data Sources" tab, click "add new data source" and follow the wizard questions. There's a list of walkthroughs:
