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:
