Multiple Selection Listbox As Data Control?
Aug 28, 2007
Hi, i have a listbox with multiple selection enabled, the end user uses this listbox to select what data they want to view eg. they select "green" to view all the green cars, "red" to select all the red cars etc.
i have the listbox as the control that is connected to the datasource (the sql used for it is select * from cars_table where color =@color
this works fine when one item in the listbox is selected, but when multiples are selected it does not work
what format does the =@color have to be when multiples are selected? i've tried "green, red" "green + red" etc. but cannot seem to get it working
does anybody have any working examples that i can take a look at? it seems to be a common action, yet i cannot seem to find any documentation on how to get it to work
thanks in advance!

Hi, im a newbie. using VB.net / visual studio 2005 and SQL express
I have pasted my page code below
Basically i have a lisbox which is bound to an sqldatasource. It allows the user to select multiple names. I then have another datasource which when the page is submitted it posts various values from different fields into my db. The insert works fine.My problem is that the multiple selection wont allow me to insert into my db, it just captures the first value.I used this sub below to prove that when i click a button on my page it takes all my selected choices and puts them inside a text box, this works i can see them all. I then bound the textbox text value to the one im inserting into the db, however once again its only inserting the first value from the text box, how is this possible, the text box shows all the values and its set to string, it should insert everything in the text box Protected Sub selectedContact_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim alternatives As ListBox = CType(UploadPictureUI.FindControl("alternatives"), ListBox)
Dim TextBox1 As TextBox = CType(UploadPictureUI.FindControl("TextBox1"), TextBox)
For intLoopIndex As Integer = 0 To alternatives.Items.Count - 1
If alternatives.Items(intLoopIndex).Selected Then
TextBox1.Text &= alternatives.Items(intLoopIndex).Text & _
ControlChars.CrLf
End If
Next
End Sub

I need to use the list of items from a multiselect listbox in a parameter of a query's IN clause.
Example:
I assemble the list from the listbox and set the paramter value so @CityList = 'London','Paris','Rome' .... etc.
A sample SQL would be:
SELECT * FROM Customers
WHERE City IN (@CityList)
However, the SQL will not work. It seems the whole string is put in
another set of single quotes by the compiler so it's treated as one
string literal instead of a list.
Is there a way around this?

Hi,
I have an ASP.NET form that stores it's data in MSDE but I just added a multi-select ListBox to the form and I'm having a hard time coming up with a way of writing that data to the database. Should I write the values into a column on the same table where I store the rest of the data from the form (values separated by a comma) or shouild I create another table (one to many) and store the data there. I like the second option, but I'm not sure how to loop through each value and write it to the database table.
I grab the values for the selection as follow:
foreach (ListItem lstItem in lbAttendees.Items)
{
if (lstItem.Selected == true)
{
grpList.Add(lstItem.Value.ToString());
}
}
but I'm not sure on what to do next and could use some help.
Thanks

I have a sql server database linked to my application. I have a table that I want one of the columns (Service Perfomed) to load in a list box. When I start the application nothing appears in the list box. What could I be doing wrong?
Here the code the visual studio created:
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
Me.ServiceTableAdapter.Fill(Me.MaintenanceRecordsDataSet.Service)
End Sub
I've tried combo box, text box and these seem to work fine but not the list box.

NET 2.0
I am using Visual Studio Express 2005 for database web developement.
I have created a database with 5 tables. Two are associative tables.
They are
SoftwarePK SoftwareID Title
SoftwareSolutionFK SoftwareIDFK SolutionID
SolutionPK SolutionID Title
CategorySolutionFK CategoryFK Solution
Category
PK Category Title
Criteria for a search with three sources of input into a SqlDataSource attached to a FormView for paged out.
The following are the Search Criteria input sources:1) ListBox in Multiple Selection Mode2) CheckBoxList with Mutiple checks posible2) TextBox with key word search in Title.
Each Solution has 0 or many Categories and 0 or many Software.
When the records are entered in the database, the associative information for Categories and Software are populated to filter thereturned values.
In NET 1.1, I would create a search string like the following in code behind by looping through the CheckBoxList and ListBox finally adding the TextBox:
SELECT Solution.SolutionID, Solution.Title FROM SolutionWHERE Solution.SolutionID IN ('2','3','5') AND Solution.Title LIKE '%Math%'
I am unable to update the SelectCommand in the ASPX page.
However, when I use the I have used theSystem.Web.UI.WebControls.SqlDataSources"SelectQuery Builder"I receive the following in the Source for ASPX: <asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT Solution.SolutionID, Solution.Title
FROM
Solution INNER JOIN CategorySolution ON Solution.SolutionID = CategorySolution.SolutionID
INNER JOIN SoftwareSolution ON Solution.SolutionID = SoftwareSolution.SolutionID">
<SelectParameters>
<asp:ControlParameter ControlID="CheckBoxList1" DefaultValue="%" Name="CategoryID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="ListBox1" DefaultValue="%" Name="SoftwareID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="txtTitleSearch" DefaultValue="%" Name="Title" PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource> I receive duplicate records and not sure if the code generated accesses the Mutiple Selected values in the CheckBoxList1 and ListBox1.Question: 1) If the SelectQuery generator will not access multiple selected values from the CheckBoxList1, how can I use code behind to replaceSelectCommand in the ASPX page?2) What is the best solution for using the CheckBoxList1, ListBox1, and TextBox for filtering my results? Sample code, references to solutions, corrections on logic, a new approach, how to use the wizard correctly would all be greatly appreciated.3) Can Multiple Selection Controls be use with a SqlDataSource SELECT Command?Thanks for your time,Sincerely,Unhistoric

Hi
I am developing a program on Visual Basic 2005 to a pocket pc, I want to make the SQLceconnection but It says that the file doesn´t exists, I use this code:
Dim conn As New SqlCeConnection()
Dim Recordset As SqlCeDataAdapter
Dim SQL As String
Dim ds As New DataSet
conn.ConnectionString = _
"Data Source = '.BDDclimatologicos.sdf';"
conn.Open()
SQL = "select [Provincia] from ZonasClimaticas"
Recordset = New SqlCeDataAdapter(SQL, conn)
Recordset.Fill(ds, "ZonasClimaticas")
lstboxProvincias.DataSource = ds.Tables("ZonasClimaticas").DefaultView
I have Dcilmatologicos.sdf on a folder named BD next to the folder of the executable, I don´t know what happends.
My database has one table "ZonasClimaticas" and a column named "Provincia" on that, my other question is:
Is this the right code to show that column on a listbox?
Thank you very much!

I'm trying to run something like this:
Select ID, FIRST(forename), FIRST(surname) from table1
GROUP BY ID;
I know First doesn't work in TSQL, I used to use it in Access and now need to run something like that in TSQL. Simply getting unique ID with first forename and surname, cause there are some dupes in a table.
There are records like:
ID     forename    surname
--------------------------------
1   John   Kormack
1  James Dope
2  Erin   Dupes
3  Will Hugh
3Â Â Â Walter Heisenberg
So I want to pull out:
1 John Kormack
2 Erin Dupes
3 Will Hugh
How can I run it in TSQL?

I have the following data (very simplified version)TransactionId Agent_Code------------- ----------191462 95328C205427 000024C205427 75547CAgent Code 75547C is a corporate agent. The others are not. I have alist of corporate codes so I can query against it, BUT what I want todo is...Return a unique TransactionId and max of the AgentCode, but if theAgent is a corporate agent, I need to return max of the corporate agentcodes. We can have multiple agents against the transaction andsometimes have a mix of corporate and none corporate agents. What weneed to do is see the corporate adviser if there is one. I only want 1record per TransactionId.We derive more data (sales hierarchy) from this, so are not interestedin anything other than the maximum, but need to know if it wascorporate which therefore gives me a different hierarchy later.Ideally I want to do this in a view and not use an SP. I can then usethis in my main view. If I have to resort to an SP, then so be it, butI would appreciate any helpful comments (or even better, the answer)ThanksRyan

How can I add multiple rdlc report definitions to a single Winforms ReportViewer control? I would like to start with the first rdlc and concatenate subsequent rdlc files after that. I want the user to be able to scroll through several different rdlc report definitions as if they were all just one report.

Hello all,
Is there documentation somewhere about multiple execution paths in SSIS control flow? I didn't find documentation anywhere. I have a situation where I have two tasks that take considerable time, but could be executed in parallel (to speed up things) and I was wondering whether SSIS supports parallelism.
To illustrate the issues in simultaneous execution, I created a test SSIS package. In the package, I have five tasks, let's call them T1, T2, T3, T4 and T5. The taks are connected with "green arrows" like this:
T1->T2
T1->T3
T2->T4
T3->T4
T5 is not connected. The tasks can be e.g. Send Mail tasks, that's not relevant to this issue. I put a breakpoint in each task and execute the package.
When I execute package, T1 and T5 become active, i.e. the arrow that displays where the package execution currently is, is in two tasks simultaneously. Now F10 (step over) doesn't seem to work "Unable to step. Not implemented". If I press F5 nothing happens. After I press F5 for a second time tasks T1 and T5 and executed. Why don't they execute with the first pressing of F5? I would additionally like to know whether these two tasks are executed in parallel or sequentially, i.e. in the same thread or in two threads? Is there documentation of this?
The execution stops at T2&T3. Again, pressing F5 doesn't do anything, but the second time I press F5 T2 and T3 are executed.

Dear Friends,
In my report, I am having Listbox for users to choose Country, City & Company.
The user can choose Country. Based on the country selection, cities will be listed out.
Based on the city selection, Companies will be listed out.
They can choose companies.
Now, I have to show two set of results.
A. List of Companies as per selection ( dataset with equal to selection )
B. List of Companies which are not selected ( ie dataset with not equal to selection )
I have created a dataset with all companies and filter it by selection. When I tried with the filter option in the Dataset, I am able to check for only one value and not for multiple value. If the selection is one company, then I can filter it. But if they choose 5 companies, I am not not able to filter it. Is there any other option I can try out.
Please advice. Thanks.
warm regards
Rakin
Singapore.

hello all,
i am making a query which select the data again a particuler date.
I insert values in the table for with current date(Today's date) and the records is inserted with the date format(2006-07-14 16:12:09),now when i run the query after 2 or 3 minutes to select the records inserted today, my query returns no results.
I think it is because of the the time (14:16 in this case) that after 2 minutes, the query looks for the records inserted at (2006-07-14 18:12 or 2006-07-14 19:12) and does not get the result.
Is there a method to not consider the time(14:16) when running the query but the query fetches the records including the records inserted at this time(14:16) no matter at what time I run the query today?
Please anyone help me!
Thanks in advance!

I have used my parameter value in where clause of my dataset control SQL query. When I choose a single value in my multiple-value parameter then I get output as expected. Hovewer when I choose multuple values I get an arror:
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
----------------------------
Query execution failed for dataset 'DATABASE'. (rsErrorExecutingCommand)
----------------------------
An error has occurred during report processing. (rsProcessingAborted)
I am convinced that it's a syntax problem. Is there a way I can change syntax of data output from query:
select @parameter
I need output to be like: value, value, value ... etc.
The dataset control query looks something like the following:
select
ID,
a,
b,
c,
d
from DATASET.dbo.Table
where ID in (select @parameter)
I have been searching through google for weeks to solve this and got this far and got stuck. Is it possible at all to achieve what I am looking for?
