MYSQL responding very slow
Hi Experts,
I am using MYSQL database as a backend to my VB.NET web application.
I have used RADCOMBO feature to populate data from MYSQL Query. There are approx 8 comboboxes which are interlinked with each other. That means on selecting the first combobox value the second combobox will show filtered records according to first one and so on...
For filling the combobox it takes time approx 1-2 minutes for each. The filling the combobox returns the correct value.
It's only taking time to query it with MYSQL..
How to get rid of this issue?
My sample code is as below :
Sometimes I also getting error related to 'Postback' due to this issue...

My sample code is as below :
Protected Sub rdSls_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)
Dim conobj As New connection
Dim conn = conobj.makeConnection
fillobj.radFillCombo(rdSls, e, "nSlsID", "sSlsNo", "tsls", " and nOrderStID <> 6", conn)
conn.Close()
End Sub
Protected Sub rdOrd_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)
If rdSls.SelectedValue <> "" Then
Dim conobj As New connection
Dim conn = conobj.makeConnection
fillobj.radFillCombo(rdOrd, e, "nSlsDetID", "sOrdNo", "tslsdet", " and nSlsID=" & Val(rdSls.SelectedValue) & " and sOrdNo <>'' group by sOrdNo", conn)
conn.Close()
End If
End Sub
Sometimes I also getting error related to 'Postback' due to this issue...
