.NET - Getting DataGridView To Populate From Stored Procedure?
Mar 12, 2009
I was just handed a VB.NET prototyping effort, and I'm not very experienced with VB.NET.I had to create a stored procedure which returns a self-referential table in order. Once, I completed that I wanted to get a DataGridView to show the results.
Previously, my team has been doing a lot of this via the GUI designer of VB.NET so I don't have a ton of code to describe, unfortunately.I was trying to follow their pattern which I will briefly describe here:
I have a DataGridView whose DataSource property points to a BindingSource. The BindingSource points to a DataSet. The editor for that DataSet calls a TableAdapter which gets the data from the stored procedure.
I previewed the data for the TableAdapter. The data is there. On frmMain's load the TableAdapter's Fill command is run. Not seeing anything. And my hunch is that this is way too complex a process to be correct. Or maybe not. I did a lot of Google searches before I decided to bother you fine folks.

Using SQL Server 2008 I created a Stored Procedure called MyStoreProc and it runs fine from the Management Tools.
In VB.Net 2008 I created a new dataset and a new TableAdaptor. In this table adapter I created a new Query called FillByGrid and selected the Stored Procedure. Previewed data and it previewed correctly.
On a form I created DataGridView and selected the Table Adapter from the dataset.
I ran the app and no data is shown. Visual Studio autocreated the code below and I changed it to select the the Query I just created:
Me.MyTableAdapter.FillByGrid(Me.MyDataset.MyTableAdaptor)
No data is shown on the grid so I tried the manual approach:
' Create the dataset
Dim da As New SqlDataAdapter, ds As New DataSet
Dim conn As New SqlConnection
[Code]....
Still no data shown. However stepping through the I can see that the connection is open, and "da.Fill(ds, "tbl1")" takes a little bit of time as it is running the Stored Procedure and ds table has the correct number of rows and columns. Its just not being shown on the datagrid.
Creating another table adapter in the dataset and returning data from a database table using a standard select * from table command display in the datagridview fine.

I'm having a devel of a time getting what I figure is something simple to work.
I need to set up a Combobox where the list of items is created by accessing a stored procedure.
The SQL code is simply (I left off the code to create the sp);
SELECT ItemCode
FROM vw_CodeList
GROUP BY ItemCode
ORDER BY ItemCode

The store procedure which give me the information I need is:
USE [UCSMIS]
GO
SET ANSI_NULLS ON
[Code].....
When I try to add it to my report it gives an error, is it because of the temp table and how should I go about it?

I've noticed that I can use LINQ to call a SQL Stored Procedure and use those results in a datagridview and have sorting by column automatically included. However, if the LINQ call is done on a web service, it seems like I have to return the results as an array which, when it gets back to the client, doesn't have the interface needed by the datagridview control to do it's sorting. I haven't been able to find an easy way to get the sorting ability back.
I've tried to serialize the result on the web service but the returned type can't be serialized. I tried putting the data context in a common DLL so I could use the Attach functionality but that doesn't exist for stored procedures. I suppose I could make a table in the data context just for this purpose but that will be a pain to maintain. Would I just be better off skipping LINQ and using an old fashioned typed dataset for this?

I have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]
Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.
I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.
If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.

Using VB2008 How can we fill the datagrid with information from a stored procedure and a sp variable.We have a dataset named: DBnamesDataSet, a source: ShownameBindingSource and a adapter: Show_nameTableAdapter.
Stored procedure:
alter PROCEDURE [dbo].[show_name]
@name varchar(50)

I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.

I have noticed the following but unable to understand why.Whenever a procedure is called in .net it takes more time than when it is called subsequently.Even if a procedure is called after some interval it takes more time than it takes if it is called quite frequently. i am not asking about sql query or sql command. any user definded function or user defined method takes much more time to finish when it is called occasionaly. but when the same procedure is called quite often it finishes a lot faster. why?

I am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.
So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.
CODE:
I'm not sure if you need to see any of my ASPX or my SQL. both work fine on their own, but i am not able to get these buttons to work.

I have a stored procedure that when I run it within my application it times out, but when I use Management Studio and pass in the same exact parameters, the stored procedure executes under a second. I had this exact same issue with the same stored procedure before, and all I did was recompile it, and it fixed the problem, but I do not want to keep having to recompile this stored procedure every few days or so. Has anyone else ran into this issue before?
Another note I would like to mention, is that I'm currently working on a test database, so I'm not inserting, deleting or updating any of the records that the Stored Procedure is using. So the database itself is not changing, but for some reason the Stored Procedure is showing degradation, and at the most we have 2 users in the database at a time.
Below is the code I use to call the Stored Procedure from my app.
cmd.CommandText = "sp__RECAP_SELECTION_GET_GRID_RECORDS_RECAP_TYPES"
cmd.Parameters.Add("@FK_KitchenID", SqlDbType.SmallInt).Value = cmbKitchenCustomer.KitchenID_SelectedPrimaryKey
[Code]....
As I mentioned, if I run the Stored Procedure within Mangement Studio, it runs with no problems. Also if I recompile the stored procedure, it runs fine within the app, but after a few days, the stored procedure starts to timeout again within the app and I need to recompile it again.

I am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).

I am trying to get some data relevant to a stored procedure (or funtion) back from a database using .Net. The first thing I need to be able to do, is get the stored proc from the database and turn it into string format.The information I need is: The return set of columns, tables used within the SP, Stored Procedures called from the SP. The only way of doing this at the moment that i can think of, is though parsing the text and looking for keyword matches.

I am a newbie to vb.net and sql server. My responsibility is to build a vb.net function that when a scanner scans an object, it would take the scanned string and call a stored procedure to get a row of data that match that scanned string and pass the data row to an application that would print out a label.below is my vb.net and sql server stored procedure script
1. Do I have to come up with a public class in order to store my row of data to pass it on to a different vb.net application that would take that data row and print out a label?
2. In my stored procedure, how would I return the founded data row to the vb.net function?
Module makeLabel
Public Class AMGCdata
Public fileName As String[code]...........

I'm having problems trying to create a new stored procedure.I am using sql 2005 express. I also have sql server management studio express installed.I open up the studio express and goto the database that i want to use to create the stored procedure. When I right click i see a sub menu, but don't see a option that says create stored procedure ( or any option that has anything to do with stored procedures ).Am I right in saying that I need the full version of visual studio to be able to work with and create new stored procedures.I am also told that sql server comes with built in stored procedures. Am i right in assuming that I can call these without having visual studio installed. And if the answer is yes, then how do I find out the name of these procedures, the parameters they use and what each particular stored procedure does.

I've added few stored procedures to my SQL Server 2005 database. Few of them were a procedures containing SELECT statements and one of them contains INSERT statement. While executing the procedures with select statements are as easy as displying tables, the procedure with INSERT statement is not so easy [for me].At first, i've tried to add the procedure to the dataset and execute it as others, by filling the table adapter. But... there is now way to access the tableadapter within the code... VB does not recognise it! Just like it wasn't there! It's not even listed on with the other tableadapters below my project. It's viible only in the dataset!After few minutes i've removed the procedure from the dataset and tried to add it as a query. Everything seemed to be ok... but... after naming a function, that would execute the query.... the function is visible nowhere. I can't execute it within the code.
