Filling a grid

[Jennifer]

I'm trying to fill a datagrid on a VB ASP web page. No data is
showing up on my grid and I'm not sure why.

The code is as follows

Dim dvMain As DataView
Dim X As Int16
Dim dtMain As New DataTable()
Dim DR As DataRow

'Note - GetDailySales is a function that successfully returns a
dataview.
'I am not worried about this.

dvMain = GetDailySales(txtUnitID.Text, "8/1/04")

dtMain.Columns.Add("Unit")
dtMain.Columns.Add("Date")
dtMain.Columns.Add("User")
dtMain.Columns.Add("Eve Deposit")
dtMain.Columns.Add("EB Desposit")
dtMain.Columns.Add("Day Deposit")
dtMain.Columns.Add("Special Deposit")
dtMain.Columns.Add("Total Deposit")
For X = 0 To dvMain.Count - 1
DR = dtMain.NewRow
DR("Unit") = dvMain(X)("Unit_ID")
DR("Date") = dvMain(X)("Business_Date")
DR("User") = dvMain(X)("User_ID")
DR("Eve Deposit") = dvMain(X)("Deposit_Eve_Amt")
DR("EB Desposit") = dvMain(X)("Deposit_EB_Amt")
DR("Day Deposit") = dvMain(X)("Deposit_Day_Amt")
DR("Special Deposit") = dvMain(X)("Deposit_Special_Amt")
DR("Total Deposit") = dvMain(X)("Deposit_Eve_Amt") +
dvMain(X)("Deposit_EB_Amt") + dvMain(X)("Deposit_Day_Amt") +
dvMain(X)("Deposit_Special_Amt")

Next
dgSummary.DataSource = dtMain
dgSummary.DataBind()
This code is in a button_click. I would expect my grid (dgSummary) to
fill up with the data, yet it doesn't.

I'm sure I'm missing something really obvious here, but it has been
more than a year since I've even looked at .Net... If anyone can tell
what I'm doing wrong, I would greatly appreciate it.

Thanks,
Jennifer
