FormView EditItemTemplate DropDownList loaded from codebehind via stored procedure

Posted By:      Posted Date: September 04, 2010    Points: 0   Category :ASP.Net
I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate.  I present the data in a FormView ItemTemplate using text boxes.  When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.  I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course .  This project is different in that I want to get the data from a stored procedure on a MSSQL server. In my latest attempt, I can see the data in the datasets.  I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value" I include the code below.  If someone could point me to an example I would be greatful.  There has to be an elegant way of accomplishing this. Thank You, rlbaum *************************************************** <EditItemTemplate> <asp:Button ID="updatebutton" runat="server" CausesValidation="false" Text="Update&quo

SqlDataSource, FormView, and Update with stored procedure in code behind

Hello, Using a FormView with a SqlDataSource, I'm attempting to Update data by calling a stored proc in code behind. I was having trouble getting parameters using Update Parameters in the SqlDataSource, but found a working solution by coding the parameters. The problem now is I'm getting an "Updating is not supported by data source 'XYZ' unless UpdateCommand is specified'. I saw some previous posts on the forums, but didn't find them very enlightening. 

Send Email from SQL Server Express Using a CLR Stored Procedure

One of the nice things about SQL Server is the ability to send email using T-SQL. The downside is that this functionality does not exist in SQL Server Express. In this tip I will show you how to build a basic CLR stored procedure to send email messages from SQL Server Express, although this same technique could be used for any version of SQL Server.

If you have not yet built a CLR stored procedure, please refer to this tip for what needs to be done for the initial setup.

Inserting rows via stored procedure and under certain conditions


I'm using Dynamic Data with Entity Framework in VS2010.

Let's say my table has these fields:

PersonID (FK)
LocationID (FK)

Hypothetical scenario (it's easier for me to explain this way, so just bear with me for now)... But let's say each row in the table represents "how many items were sold by such-and-such employee at such-and-such location," where location and person are foreign keys which are referencing other tables.  Basically, there should be no more than a ONE row which has a particular combination of Person and Location.  Makes sense?

So, when inserting new rows using my Dynamic Data app, the insert form displays editable fields for Person (dropdown), Location (dropdown), and Items Sold (textbox).  How do I prevent users from inserting another row into the table containing an already-existing combination of Person and Location?   How do I displaying useful feedback to them in the event that they DO attempt to do this?

I have several thoughts about this, but since I'm new to Dynamic Data, I'm not sure which way to go.  For example:

Option 1:  Use "cascading dropdowns" approach in the insert form and only pull in the "allowed" combinations of the two dropd

Creating A Stored Procedure Which Searches Team Names

If anyone done anything similar to my request please let me know.

Call SQL Stored Procedure Asyncronously



I have a C# web page that calls a stored procedure. The page passes few parameters to the stored procedure and call it. The stored procedure does so many time consuming tasks on a huge number of database records but does not return any value.

Since the page is not expecting any return from the stored procedure, I want to execute the stored procedure asyncronously so that the user can continue working on the web page and other web pages while the stored procedure is running in the background. Also, I do not want the web server processes to be busy with the running stored procedure.

Any help, please.

Best regards,


Help with displaying formview based on dropdownlist


I have a formview1 with a dropdownlist1 in the insert template. Based on the value of that dropdownlist I would like to display a second formview on the same page in insert mode so that I can write data to two different tables.

How can I accomplish this?

Is this the best way to do it?



Unable to select any stored procedure while creating TableAdapters in wizard


I'm using VS 2008 and SQL 2008.

I have created the tables and the stored procedures in SQL 2008.

In VS 2008, I created DataSet1.xsd in App_Code and created the connectionString in web.config file.

Then when I go into the DataSet1.xsd and try to add a TableAdapter, strange things happened.

First I chose the data connection, then selected "Use existing stored procedure", then there was nothing listed in the dropdownlists (in Select, Insert, Update, or Delete). 

I'm sure the connectionString is correct because if I choose "Use SQL statement" and type in a "select * from mytable1", the TableAdapter can be created without any problem.

Any suggestions?

Problems connecting stored procedure to Crystal Reports


I am working on updating a reporting system that uses Crystal Reports.  All of the 250+ reports were created in CR 8 and I have been opening up the old files in Visual Studio 2005 and updating the database location.  All I have had to do with all connections to views and even a couple of stored procedures is create a new connection to the database and then update the old report's datasource location.  The reason I need to update the location is so that the .NET application will use the correct driver.  Everything has worked fine up until I got to one stored procedure.  The old version of the report works perfectly with the stored procedure, but when I try to run the report using VS 2005 I keep getting errors.

First I connected to the database using the Oracle OLE DB provider, then updated the location of the stored procedure in the report.  It then prompts me for the two parameter values for the stored procedure, both of which I keep as NULL so that the report parameters will be passed to the procedure.  Then I get the following error:

Query Engine Error: 'ADO Error Code: 0x
Source: OraOLEDB
Description: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'STORED_PROCEDURE'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored'

Trying to run a stored procedure from vb code with oracle data provider.



Here is my SP:

create or replace
 Open p_getuserssignon_recordset1 for
 SELECT Distinct(Userid), UserPassword, SecurityLevel, ActiveStatus
WHERE substr(UserId,1,2) <> vUid
Order By UserId;

I would like to run this SP from code and fill a gridview with the result. 

I am not sure how to go about this, as I have found several different examples, other than the one I  think I need.

I am using the oracle data provider and I have an input parameter (vUid, which will equal "zz").

First question. When filling a gridview with a result set from a stored procedure should the recordset OUT be defined as a REFCURSOR (like i did above)? 


Do you have example code as to how to execute the SP and fill a gridview?  I keep trying different variations of code i've found on the internet without any success other than getting more confused.

(I am using VS 2005, VB).

Thank you.



Using the BDC API how to catch the returned code when executing a stored procedure?

using BDC API, how can i catch the return code a stored procedure returns?

I tried Entity.Execute to execute a generic method. However, it returns an empty Entity table.

I know you can do it by setting up an output variable. I prefer returning an integer for tracking errors.

Any ideas?



Formview PagerTemplate DropDownList Navigation


Does anyone know if its possible to use a DropDownList within the PagerTemplate to navigate to a specific record?  I have been able to place the DropDownList outside of the FormView and PagerTemplate and make it work, however, I can't get it to work inside the PagerTemplate.


Formview + EditItemTemplate + Bind + PageLoad + Prerender = Confused


I am working with a formview edititemtemplate.  Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values.  These dropdown values get binded during page load.  I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.

I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback.   I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render.   I'm just not sure how to get the stars aligned here.

The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender.   However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.
