Populating GridView With Data From Stored Procedure
Jun 10, 2011
I have the following code in my asp page:
Imports System.Data.SqlClient
Imports System.Data
Partial Class _Default
Inherits System.Web.UI.Page
[Code] .....
And while the page doesn't throw me any errors, I'm also not seeing any data in my datatable.
I have two GridViews, the first works fine as I defined the datasource when I dropped it onto the asp page via visual studio and I specified the table to use.
The other GridView (dgvParams below) has just been dropped onto the asp page and I want to use it at run time[code]...
When I step through the code I can see row and column counts are as expected and call "dgvParams.DataSource = table".
Im desperately trying to populate my Listview called "Listview1" with my stored procedure that I have create on my SQL Server 2005. Ive got quite far as seen below but I still dont know to to effectively populate the Listview1 with the data retrieved from my Stored Procedure. The below connection does work but I dont know how to use it now with my Listview.
Imports System.Data.SqlClient Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I am trying to execute a stored procedure and place the information in a datagrid(without using the .net wizard) i want to do it manually. Using ado.net i believe. I am using vb.net and asp.net
Public cmd As New SqlCommand() Public saoda As New SqlDataAdapter(cmd) Public conn As New SqlConnection(" ") Dim saods As New DataSet
i have a gridview, linked to a sqldatasource. I have added a stored procedure to delete from multiple tables, and then enabled deleting on the gridviews smart tag.
When i click the delete button i get an error message, "Object must implement IConvertible". I read that it is a problem passing the parameter to the stored procedure, possibly the wrong datatype being passed. Im not sure if i am passing the parameter to the stored procedure at all. The parameter should be the gridviews datakeyname, in this case it is "UserId".
The stored procedure works i fine in management studio, so i think it is just the parameter being passed (or possibly not being passed)
Do i have to code the parameter in the code behind to be passed to the stored procedure?
I've got a stored procedure that right now generates a gridview. From that gridview, users want to be able to click on a button, and export it to Excel, where they can manipulate etc locally.But I used this
Dim sw As System.IO.StringWriter = New System.IO.StringWriter Dim hw As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(sw) gv.RenderControl(hw) Response.Write(sw.ToString) Response.End()
and from that I get a message every time it goes to excel,"The file you are trying to open,'Defauly.xls', is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" Users don't want that message.. but I can't find any way of getting rid of it.any solutions that does not involve tinkering with system registries (it's not feasible for this project)?
My other option is to convert the gridview to a datatable, and have another process do the export. But I'm stuck on the part where I dynamically create the columns and column names from the gridview (or stored proc for that matter).. . it won't always be the same amount of columns etc, so I can't hard code that in.
I am having trouble retrieving data from a stored procedure that I have set up as a Data Adapter using VB.NET 2005. The Database is SQL Server 2000, and what I am trying to access is a simple Stored Procedure that will validate a users login access. [code] I have a dataset set up as AdjustmentsDataSetspValidateLogin. I am trying to figure out in code how I can address this using a table adapter or how I can capture from a login form I have created the UserID and pass this value to the stored proc to return the current record, if any of the user.I initially setup a Dataset and dragged the dataset onto a form. Then I deleted the data navigator and the toolbar that was created by default so that I could just pass values to the Stored Proc. I also have the table adapter setup to return a table "LoginData" with the two fields Approver & Admin when I pass a userID.But I am having difficulty addressing the table adapter in code and pulling back the data values for the UserID I'm passing to the DataSet.Does anyone have any ideas on how I can call this stored proc and get the data values returned? I'm new to .net programming. [code]
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 am trying to find examples of getting data back from a stored procedure that has no parameters sent to it nor has any returned output parameter. Though it does display data.How can i get that from my code im using below?
Dim myCommandSQL As New SqlCommand Dim myReaderSQL As SqlDataReader = Nothing Dim intX As Integer = 0[code]....
The @return_value i just put there to see what would happen but i got nothing returned.
I'm using Microsoft .NET Framework 3.5 to create a web service with VB.NET. I'm using a Stored Procedure in SQL Server 2008 so that SQL can insert all the data that I'm passing. The problem is that in one of the servicse I need to pass around 10,000 records and it's not very efficient to run the stored procedure 10,000 times.
I wish to create a stored procedure with multiple select statements. In addition, I then want to access each of the statements on the page load event. The purpose of the statements is to create multiple 'counts', and a number of labels on the page will each contain an individual returned count. At the moment I have created a basic stored procedure with two select statements:
CREATE PROCEDURE [dbo].[Finance_CustomerCount] AS SELECT COUNT(Quote_ID) AS Count1 FROM dbo.generatedquotes WHERE (status = 2) AND (Contract_End_Date >= GETDATE()) OR (status = 4) OR (status = 7) OR (status = 1) SELECT COUNT(invoice_id) AS Count2 FROM dbo.invoices GROUP BY invoice_open HAVING (invoice_open = 'Y') RETURN
I can then access the result of the first select statement by using this code: Dim newconn As String = Session("ConnectionString") Dim connection As New Data.SqlClient.SqlConnection(newconn) Dim MyCommand As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand("Finance_CustomerCount", Connection) [Code] ....
So what I basically need to know is, how do I access the second select statement result set for another label.
I would like to bind textboxes to certain columns from records generated from a stored procedure. The error I receive is "DataMember property 'spCustomerHeader cannot be found on the DataSource". I have no problem returning the data to a datagridview but I need this show this data in textboxes.
I found a few examples online on how to import excel into sql via vb. but can i do it via stored procedure? Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D: esting.xls;HDR=YES', 'SELECT * FROM [SheetName$]')
So like, can I pass in: ('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D: esting.xls;HDR=YES', 'SELECT * FROM [SheetName$]') As a parameter to SQL Server SP?
I am trying to execute a stored procedure and place the data in a datagrid manually (without using the .net wizard). I am using vb.net and asp.net in visual studio.Here is my code but I can't figure out where I'm going wrong.
Imports System.Data.Sql, Imports System.Data.SqlClient Imports System.Diagnostics Imports System
I'm currently writing a small app that takes data provided by an SQL stored procedure and makes it available for easy export for non-tech savvy users. I'm trying to make this as generic as possible, in that you should be able to plug in just about any SP and follow my template to have an export utility. I'd like to add a way to get the column names before running the SP from the SP itself. I had assumed you could just run the SP with impossible values so nothing is returned, then get the columns from the resulting VB.NET DataTable. However, if there is no data returned, the column names aren't returned either. How can I get the column names from the SP without having to hard-code them?
I created a sql stored procedure that will insert data for me depending on user input. Now I would like to know usually I would do something of this nature
Dim con As New SqlConnection(connectionString) Dim cmd As New SqlCommand("usp_userinput", con) 'references connectionstring and calls store procedure cmd.CommandType = Data.CommandType.StoredProcedure 'sets default to be storeprocedure lblMessage.Text = String.Empty With cmd.Parameters If (Session("UserInitials")) IsNot Nothing Then .AddWithValue("@UserInitials", Session("UserInitials").ToString()) End If End With
That is just an example how i usually approach calling the stored procedure in vb. However for this particular form I am going to have 50 or 60 textboxes which each one would require a session state variable.Seems a little tedious to have to create a session state variable for each textbox on the form.
Can any one provide me the link or give me an idea how to read all the tables returned by SQL Stored Procedure?
My Stored procedure returns two tables:
ID Name ----------- 1 Jeff 2 Joe
ID Pages ---------- 1 2
i want to read data from both of these tables. I tried using SQLDataReader and then populating into datatables but then i can only read the values of 1st table. I want to read both the table values. How do i do it? please let me know if you guys have any ideas how to deal with this.
I have a task to create a web service to receive client-side app's http request(with rpc={json data} in the end), deserilize it and put he parameter in stored Procedure in order to retrive data from sql server. the procedure query and client-side's app are already there and the return data to client-side app is JSON too
I am trying have a data grid selection populate a form. I am new to this.Basically I have a connection persistance object and I would like to call that and call a stored procedure with the value of the selection. The datagrid is bound to an object.
[code]Whenever my GridView populates, if there is no value to return from my _dataSet for a field, my GridView stops populating after that. Shouldn't it skip that and continue populating the rest of the grid? It seems the GridView won't accept an empty/null value. is?
I have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.
I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB
I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:
Name question answer ----------------------- Joe question1 answer1 Joe question2 answer2
[code]....
But I would like to change it, so that each question is a header, like this:
Name question1 question2 question3 ---------------------------------- Joe answer1 answer2 answer3 Jill answer1 answer2 answer3
This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:
I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?
I want use a stored procedure in my project but I have no idea about it. Please could you tell me a little bit about how to use I can use one in my vb.net application ?
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.
