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.


Imports MySql.Data.MySqlClient
Imports System.Data
 
 
 
Public Class frmLookupInvoice
 
    Private Sub frmLookupInvoice_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        Dim conn As New MySqlConnection
        Dim myCommand As New MySqlCommand
        Dim BindingSource1 As New BindingSource
        Dim myAdapter As New MySql.Data.MySqlClient.MySqlDataAdapter
        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
 
    End Sub
End Class

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:
