[Data Binding] slow ?

[Agnes]

I got a tables which got 10,000 records.
user will input the invoice no as key.
my strConnection = "select * from invoice_Table where invno ='" &
(Me.txtInvoiceN o.Text) &"' "
in my form, there are over 20 textbox.
If i use databinding to bind each textbox. will it become slow ???
if i move the position, will it slow ??

Thanks

10,000 is a lot of data, but it depends on a lot of things. I try not to
push about 5k as a rule, but I've done about 20k and not had any performance
issues on P4's all of which had 256 mb.

Hi Agnes,

my strConnection = "select * from invoice_Table where invno ='" &
(Me.txtInvoiceN o.Text) &"' "

Do you have invoices with 10000 rows?

By the way, you better can use a command.paramet er to fill that variable in
the selectstring

If your using a dataset (especially a typed one) use the BeginLoadData
method.

i.e.

Dim myStrongDataset 1 as new myStrongDataSet 1

myStrongDataset 1.MyTable.Begin LoadData()
myDataAdapter.F ill(myStrongDat aset.MyTable)
myStrongDataset 1.myTable.EndLo adData()

this turns off notifications which can cause performance problem.s

You can also use the currency manager to assist this with

dim cm as CurrencyManager

cm = BindingContext( myStrongDataset 1, "MyTable")

cm.SuspendBindi ng

myStrongDataset 1.MyTable.Begin LoadData()
myDataAdapter.F ill(myStrongDat aset.MyTable)
myStrongDataset 1.myTable.EndLo adData()

cm.ResumeBindin g
