DataSource Controls :: Take Names From The Table And Do Another Select Based On That List Of Names?

Jun 1, 2010

I have been working with this database for some time. Here is the situation...

I inherited a MS SQL database that has hundreds of tables with similar data. For instance:

FordTampa_customer is a table,

ChevyAtlanta_customer is a table, etc....

All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...

So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.

All right, on to the real point of my post...

Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.

I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:


I am not sure how to take those names from the table and do another select based on that list of names.

Forms Data Controls :: How To Re-bind A Dropdown List Control In A Formview

Oct 20, 2010

I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.

When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.

Forms Data Controls :: Adding Values To A Table From Another Table Via Dropdown

Jan 3, 2010

I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.

Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.

I have the Gridview setup to show table2 data.

I created a field template and inserted my dropdown list and linked it to my table1 data source.

When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.

posting the dropdown value from table 1 into the appropriate field in table2..

Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.

ADO.NET :: Selecting Custom Columns To Bind Dropdown From A Generic List?

Feb 18, 2011

I have been facing this problem for a while now, what I exactly want to do is ->

I have a 3- Tier Application. For a table (say Employee) I have following classes in my BLL and DAL

1. Employee.cs (Contains database fields as properties)

2. EmployeeKeys.cs

3. EmployeeFactory.cs (Main BLL which make call to DAL method)

4. EmployeeDAL.cs (The DAL)

Suppose I have 6 columns in Employee table.

I know that the DAL returns List<Employee> to the BLL and then the BLL in turn gives me the Employee fields.

I have no problem accesing it.

But suppose I have a dropdownlist control and wish to bind EmplyeeName and EmployeeId with the Dropdown.

Is there any way that I can implement that my DAL returns a Generic list containing only the two fields required to bind the Dropdown.

In short i want my list to return only 2 columns, not all the 6 like the List<Employee>

How do i implement this???

Do I need to create a custom List<CustomEmployeeData>, if so how can i implement it in the 3 tier application.

Basically i m looking to increase the efficiency by getting less data from database. Am i on the right track????

Bind Datafield To Dropdown List With Hard Coded Values?

Jan 19, 2010

I have a dropdown list with hard coded values:

<asp:ListItem Text="One Day Shoots" Value="1" />
<asp:ListItem Text="Multi-day Shoots" Value="2" />

I want to use this to insert and edit values from a db. For example when adding a record the user selects 'One Day Shoots' and 1 gets inserted into the database. Then if the user goes to edit the page since the value in the db is 1 then the 'One Day Shoots' is selected.

One way I considered accomplishing this was by using a hidden feild - when the user selects something in the dropdown list the field is updated with the value, then when the user actually adds the record the value in the feild is submitted. I'm pretty sure this would work but is there a better way?
