DataSource Controls :: Implementing A BLL / Contacts Table, The Select Method Is A Sql Query Against A Sql Server 2000 Database?
Feb 17, 2010I'm implementing a BLL layer and have a few questions. First, in my DAL, there is a contacts table, the select method is a sql query against a sql server 2000 database. The preview data returns everyting as expected. The query is

When using the BLL method to a gridview, the results of the subquery are not displayed. There are also other methods, each having a different where clause for ContactRole_ID and each is having the same issue of not displaying the subquery reult in the gridview. No error, but no data is displayed for the subquery either. Here is the templatefield of the gridview

View 1 RepliesDataSource Controls :: Programmatically Setting ODS Select Method And Select Parameters?
Dec 22, 2010The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?

Forms Data Controls :: Get Data To DB From Listview User Entries Whithout Select, Insert, Edit Events?
Feb 24, 2011I'm using a listview control to do a survey stuff. Everything is working perfect to present the data questions, to be answered text with the different type of controls radiobuttonlists, checkboxlists, dropdownlists, etc. The admin can modify, create, change questions, answers, etc. on the survey.When it's select, edit, or insert it's easy to find the control inside a listview.However, I'm wondering how to post user's answers back to DB. How to find controls inside the listview to grab the entered data/responses from there using let's say the submit button that is outside of the listview.I believe there should be a way to do it as otherwise why we put radiobuttonlist on a listview that somebody could click it and then we should be able to get that entries. Or I'm too optimistic on this control?
View 2 RepliesForms Data Controls :: Way To Select Item In A ListView - How To Get Appropriate Index Number
Sep 7, 2010I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

View 3 RepliesForms Data Controls :: ListView Select Button Does Nothing And SelectedIndexChanged Never Fires
Jun 19, 2010I have a listveiw populated from a List<> in the code behind using the following code:
SubId = Convert.ToInt32(Request.QueryString.Get("SubId"));
using (JodyCoryDataContext myDataContext = new JodyCoryDataContext())
{
var SelectedRings = from jewlery in myDataContext.Jewleries
[Code]....
The page displays the images from the list<> and button ok but nothing happens when i click it other than postback. Furthermore even when i set up a test button wich changes the ListView.selectedindex the ListView.SelectedIndexChanged event never fires even though i can read the selected index and see that it has changed.
I'm guessing that it's something to do with using a list<> from the code behind to populate the listview but i must confess to being completely clueless.

SQL Server :: Method For Select And Non Select Queries?
Jan 23, 2011I am moving to the world of ASP.NET from an Access VBA / VB6 background and having read a few books on the subject I am still confused about communicating with SQL server in VB with ASP.NET.
As a very quick explination I am used to communicating with the server by passing strings containing the data I want to write (or read) such as:
[Code]....
I do not seem to be able to work out from ALAX, Dynamic Data, Bound Controls, DataViews, connecting to services with SOAP, DataSources and all of the other methods of database communication in ASP.NET which is the right system to do the simple reads and writes in SQL that I want to do.
At present I have a page with all of the controls on it required to collect a block of data I want to insert, it is all now fully validated but although I can build the SQL INSERT command in a string I cannot figure out how to fire it over to the local SQL Express server. Am I even doing this correctly or do I need to look at other controls?

Forms Data Controls :: Stop Databinding When There Is An Error In The Select Method?
May 23, 2010I have a dropdownlist (drpClients) bound to an object datasource (odsProgramClients). In the dropdown's databound event, I load a dynamic table based on the selected item in the dropdownlist. This all works well. However, if I force a problem in odsProgramClients select method, it continues to the databound event of the dropdown and attempts to load the table, even though dropdownlists underlying select method failed. I wish to stop the databound event from firing if there is a problem in the select method. I have code that traps the error in odsProgramClients select method.
[Code]....
[Code]....
How do I stop the dropdownlist from databinding, if there is an error in it's underlying datasource?
