Hi,
I have a adrotator control on a page, and want to program the connection of
the control via SQL.

I have the following code which doesn't seem to do much, and not sure what
else to do?


Dim SQLServerConnection As SqlConnection
Dim SqlConnectionCls As New clsSQL
SQLServerConnection = SqlConnectionCls.Connect

Dim SqlCommand As New SqlCommand

With SqlCommand
.CommandType = Data.CommandType.StoredProcedure
.Connection = SQLServerConnection
.CommandTimeout = 15
.CommandText = "sproc_GetAddDetails"
End With

Me.AdRotator1.DataSource = SqlCommand

AdRotator1.ImageUrlField = "advert_image"
AdRotator1.NavigateUrlField = "advert_URLlink"

I think you forgot to get the data

AdRotator1.DataSource = SqlCommand.ExecuteReader
 
Hi Aussie,

As Alexey has suggested, for SqlCommand object, after you initialize it,
you can call the "ExecuteReader" method (for select ) to return a
SqlDataReadere object. You can loop all the records in the resultset
through DataReader

#Retrieving Data Using a C# .NET DataReader
http://www.akadia.com/services/dotnet_data_reader.html

and for ASP.NET complex databound control, you can directly assign the
DataReader object to their "DataSource" property and call "DataBind" method
to perform databinding. e.g.

==============
SqlCommand comm;

..............


SqlDataReader reader = comm.ExecuteReader();
AdRotator1.DataSource = reader;
AdRotator1.DataBind();

Hi,

Thanks for your reply.

I am still not able to get this to work. My code is as follows. When I view
source of the HTML page, there are no values for the adrotator at all.
The Stored Proc works fine.

I can't see whats wrong......

Try

Dim SQLServerConnection As SqlConnection
Dim SqlConnectionCls As New clsSQL
SQLServerConnection = SqlConnectionCls.Connect
Dim SqlCommand As New SqlCommand

With SqlCommand

.CommandType = Data.CommandType.StoredProcedure
.Connection = SQLServerConnection
.CommandTimeout = 15
.CommandText = "sproc_GetBannerAdvertDetails"

End With

' I have swapped these arround and tried, but not working. I have put the
image/navurl after the databind.

AdRotator1.ImageUrlField = "advert_image"
AdRotator1.NavigateUrlField = "advert_URLlink"
AdRotator1.DataSource = SqlCommand.ExecuteReader
AdRotator1.DataBind()

Catch ex As Exception


End Try

Aussie,

get rid of the try..catch block, I think you will see what is wrong.

Hope it helps
 
Hi,
Sorry I actually removed the catch code to save space. There was no error
created(catch never got fired)

Thanks

Well, are you sure that sproc_GetBannerAdvertDetails is working? Try
to execute it in the Query Analizer (or any other tool to check the db
output)
 
Hi Aussie,

I'm not sure about your backend datasource. I suggest you perform the
following checK

1. Direclty bind the DataReader(get from SqlCommand) to a GridView (with
AutoGenerateColumns="true") to verify whether the reader has returned the
correctly & expected resultset

2. For databinding code logic, here is the code in my local test page for
your reference:


=================================
Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load

BindRotator()

End Sub

Private Sub BindRotator()

Dim conn As SqlConnection
Dim comm As SqlCommand
Dim sql As String = "SELECT [id], [name], [description] FROM
[RVTable]"
Dim rdr As SqlDataReader


conn = New
SqlConnection(WebConfigurationManager.ConnectionStrings("ASPNETTestDBConnect
ionString").ConnectionString)
conn.Open()
comm = New SqlCommand(sql, conn)

rdr = comm.ExecuteReader()

AdRotator1.DataSource = rdr
AdRotator1.ImageUrlField = "name"
AdRotator1.NavigateUrlField = "description"

AdRotator1.DataBind()

rdr.Close()

conn.Close()


End Sub
================================

If you have any further finding or question, please feel free to post here.
