[RESOLVED] DataGridView output not showing?

For a class project I'm supposed to write a program that requests a team as input and displays the players from that team in the first column. The players should be sorted alphabetically by their last name, and if they have the same name they should be sorted by first name accordingly. My program compiles and I'm fairly certain that I've done most of it correctly. The second column should be filled with the batting average of the corresponding player from the left column.

My problems are as follows:

1) I can't get the DGV output to show correctly, it posts the player's name with the batting average of that player in the following downward cell.

2) I'm not sure how to further use the .Split method to separate the first and last name after already separating the name from team/at bats/hits, and can't find any info regarding this topic. Also, I can't figure out how to sort in reverse, I've only seen the Ascending and Descending options so far for sorting.

3) Is the way I've figured the batting average the most efficient/correct way, or is there another better way?

Thanks in advance to anyone that helps, it's greatly appreciated by a knowledge-hungry newcomer!

Public Class danbrockplayers
    Structure player
        Dim name, team, atBats, hits, average
    End Structure

    Dim players() As player

    Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click
        gridStats.Rows.Clear()

        Dim query = From player In players
                    Where player.team = txtTeam.Text
                    Order By player.name
                    Select player.name, player.average

        For Each player In query
            gridStats.Rows.Add(player.name)
            gridStats.Rows.Add(player.average)
        Next

    End Sub

    Private Sub danbrockplayers_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Place the data for each player into the array players

        Dim allPlayers() = IO.File.ReadAllLines("Baseball.txt")
        Dim n = allPlayers.Count - 1
        ReDim players(n)
        Dim line As String  'holds data for a single player
        Dim data() As String

        For i As Integer = 0 To n
            line = allPlayers(i)
            data = line.Split(","c)
            players(i).name = data(0)
            players(i).team = data(1)
            players(i).atBats = CInt(data(2))
            players(i).hits = CInt(data(3))
            players(i).average = players(i).hits / players(i).atBats
        Next
    End Sub
End Class

1/ instead of this:

vb Code:

For Each player In query
    gridStats.Rows.Add(player.name)
    gridStats.Rows.Add(player.average)
Next

try this:

vb Code:

For Each player In query
    gridStats.Rows.Add(new Object(){player.name, player.average})
Next

2/ i didn't read the text file right through, but it looks like you can split first + last name on " "c

BAD.ASS.

Thanks dude, I've been googling around for like 3 hours trying to figure this part out on my own! I'll try your advice for my second problem when I get back from dinner.

the way you were adding, you were adding 2 items to 2 rows, instead of 2 items to 1 row.
every time you call dgv.Rows.Add it adds a new row.

I don't know why this didn't dawn on me earlier, it seems self evident to me now though, haha.

As far as using the split method goes, I understand that I can use a space character as delimiter .split(" "c), but what should I do to use that in the DGV? Should I edit my structure to include 'firstName' and 'lastName' instead of just 'name'?

add firstName + lastName members to your player structure + when querying:

vb Code:

Order By lastName, firstName _

you can continue just displaying the name + average fields in your dgv, + they'll be sorted as specified

So I can use multiple fields to sort specifically for cases like this where 2 instances of the same field might be identical?

I'm not sure if this is a dumb question, but can I use split like this:

Code:

---

line.split(" ",","c)

---

to split using space character as delimiter and also use a comma as a delimiter?

no split by ","c first as you originally were. then split name member by " "c to get first + last names

last recommendation.
try turning option strict on + fixing the errors it throws up (not my errors:D)
