dataset not saving to database - what am I not doing? :((

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :ASP.Net
Hello.  Please help me with this one if you have a few mins.  I think I'm overlooking something silly... I have a "hello world" database project.  A mdf database with 1 table "users", the table has 2 columns userid & username (both varchar(50)).  I added a dataset called Database1Dataset.xsd.  I drag the table onto it and it creates the "users" datatable.  I checked it to see if it created the insert and update commands and it has.   On my form I have 2 buttons, one for read and the other for write/save. The read button works and I can see the test records in the database; Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim da As New Database1DataSetTableAdapters.usersTableAdapter Dim dt As New Database1DataSet.usersDataTable da.Fill(dt) For Each dr In dt TextBox1.Text += dr.userid & " - " & dr.username & vbCrLf Next End Sub   The second button should add a new record and save it down to the database but this does not work.  Somehow the changes are not being commited and saved. Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim dt As New Database1DataSet.usersDataTable

Does this look correct for saving a file/ new record to a database


So thank you for all your help so far, So I think i got this right,
but would like for you all to look it over to see if there is any
areas I might run into trouble with:

//using asp.net mvc 2
the table (sql server 2005, using entities framework)
table fields

the form:
<h2> Add Media to this pattern</h2>
<% Html.EnableClientValidation(); %>
<% Html.BeginForm("AddMedia", "Pattern", new { id= Model.Pattern_Guid} , FormMethod.Post, new {enctype = "multipart/form-data"}); %>

Persist large dataset across ASP.NET pages. No database


Can anyone give me suggestions on how to implement the following requirement?

1. A online wizard (step-by step operation) processes user requests across several ASP.NET pages.  The session data is stored in memory until the user submits the request.  Once the request is submitted, a XML file is created and the data are passed to XML.

# Case Study: The parent page has a "select" button.  Click "select" will pop up a child page.  The users can select 1000+ items from a datagrid in the child page.  Once the user clicks "confirm", the selected items in the child page will be populated to the selected item gridveiw in the parent page.  The user can keep selecting more in the child page and the selected items will be appended to the gridview in the parent page.


- What's the best way to extract strings from a text file and convert to a dataset in memory and then present it in a datagrid in UI?

- What's the best way to persist and manipulate a large dataset across pages?  Session? or ViewState? Can it be accomplished by LINQ?

The app doesn't interact with a DB.  Once the request is submitted, it will convert the in memory data to a XML file.  What technology can be used to accomplished this?&nb

Why not Dataset use to Saving?


Hie Friends,

I have searched on net and even i worked on 2 huge shipping projects.

Everywhere i found that while binding data to control use dataset but when we save, they recommend use command (use generic collection and create command object with store procedure) why not we use dataset as in .NET 2.0 it is improved lot and data adapter has new feature batchupdatesize.

why we need to create property page which maps to all column in a database.

E.g. if i have employee table with empid and empname in database then i use to create emp.cs with properties of empid and empname and use same properties for saving. If i use these properties for validation in business rule then no problem. But why we use them in saving for creating command object.

insert new records in tables from dataset to database


I have 2 tables in SqlServer 2008.

Table1: T1id, SomeData

Table2: T2id, T1id, SomeData

I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns T1id in both tables.

Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.

I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".

I think i'm getting it wrong with ForeignKeyConstraints, maybe UpdateRule is not set to cascade, i just don't know.

I have been trying to work this out for 6 days now and i'm about to break something on half.

Can someone please guide me to right direction, maybe post some sample, anything.... please!

Saving SOAP to Database

Hi All, 

Web Services are very new to me and for the life of me I can not find any info on how to save a soap call/response to the database for a web service.

I did find how to trace them but not save it.

Part of my issue may be that, I am not building a soap envelope for the send. The service I am calling uses different methods to post to itself, e.g.  

api.Execute, api.Create, api.Update and api.Retrieve.

I think these methods are building the envelope for me. If I 'Go to definition' on the Execute method it takes me to the References.cs codebehind page in the application web service for this code.

[System.Web.Services.Protocols.SoapDocumentMethodAttribute("Execute", RequestElementName="ExecuteRequestMsg", RequestNamespace="http://exacttarget.com/wsdl/partnerAPI", ResponseElementName="ExecuteResponseMsg", ResponseNamespace="http://exacttarget.com/wsdl/partnerAPI", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
        [return: System.Xml.Serialization.XmlElementAttribute("OverallStatus")

DataAdaptor/Dataset problems when no row present in database tables

Hi All, I'm trying to use a DataSet to maintain some rows for a table, and when I've finished my changes, send all changes to the database using a SqlDataAdapter.    I find if there are no rows in the table in the database then I am getting a 'Object reference not set to an instance of an object' when I try to access the table in the Dataset. Is there a way to work with a Dataset like this ie. I start off with an empty table and I wish to add rows, to access the structure of the table rows, build rows, then add them and do the update on the SQLDataAdapter. Thanks, Sinead Here is my code: protected SqlDataAdapter memberDA = new SqlDataAdapter(); protected DataSet memberDS { get { if (ViewState["memberDS"] != null) return (DataSet)ViewState["memberDS"]; else return new DataSet(); } set { ViewState["memberDS"] = value; } } protected SqlDataAdapter getDataAdapterForMembers() { SqlConnection conn = new SqlConnection(); conn.ConnectionString = ConfigurationManager.ConnectionStrings["SiteDBConn"].ConnectionString; memberDA = new SqlDataAdapter("usp_GetMembers", conn); memberDA.SelectCommand.CommandType = CommandType.Stored

Updating the viewstate object before saving it to the database


I have overridden the following methods:


SavePageStateToPersistenceMedium(object viewState) 

in a class that my page derives from, so that the viewstate can be stored in DB.

Now, on page_load of my page, I am checking what control caused a postback & based on that I am forcing execution of 2 button click events in a row (by overloading those click events & calling them explicitely), but the behaviour I want is as if the execution of those 2 button click events went through the regular page life cycle.

Here is the sequence of events that happen in typical page life cycle & notice I want to alter behaviour at step 4 (on load):

1) Initialization

2) LoadViewStateData (here the viewstate is loaded from my database using the overridden LoadPageStateFromPersistenceMedium)

3) LoadPostBackData

4) Load

Here, I would like to force execution of 2 button_click events based on whether a particular control posted back.

       4.1) imgBtnPrev5_Click()

       4.2) imgBtnPrev4_Click()

Now, when the imgBtnPrev5_Click() is executed, the viewstate is already loaded, so we are fine. But after execution of imgBtnPrev5_Click(), I would like to update the viewstate object in memory & then call the o

Uploading .pdf files with FIle Upload control and then saving to database


Hi everyone!

I'd like to allow users to upload a .pdf file via the file upload control (if that's the best method), save the file to the db and then retrieve it so they can click on a link and open the .pdf they've uploaded.

I've been looking for a tutorial on how to do this but keep running into methods of saving the file directly on the server in a directory, not in SQL server  (using Linq and VB by the way)

Can someone please point me in the right direction on how to do this?   Thanks!

Create a XML file from Database table using Dataset



I've got a SQL database with a table named contact with different column such Name, Address, email ...

I would like to generate a XML file based on the table data:


     <name> John</name>

    <address> 100 main street </address>



After some research it looks like I can use a dataset from that table to create my xml.

Being a beginner I cannot find the right steps / syntax to do so.

Is there any tutorial showing how to work with dataset and XLM?

Thank you for your helps

Saving an Access database (Powershell)


Here is a fun one. I was told this is the place I’m supposed to ask so here I am.

 I am making a Powershell script that does a bunch of things. The last step is to connect to an Access Database via ADO.net and make an update. I have the basic script from the scripting guys and tried modifying it to my own needs. The Database section is as follows:


$UH = [int]"149995"
$update = " MM/DD: Add text"

$objConnection = New-Object -comobject ADODB.Connection
$objRecordset = New-Object -comobject ADODB.Recordset
$objConnection.Open("Provider = Microsoft.Jet.OLEDB.4.0; Data Source = c:\scripts\User_Help_BE.mdb")
$objRecordset.Open("Select * from [User Help Main Table]",$objConnection,3,3)


while (!($objRecordset.EOF)){
 if ($objRecordset.Fields.Item("ID").Value -eq $UH) {
   $objRecordset.Fields.Item("Tried").Value = $objRecordset.Fields.Item("Tried").Value + $update
	 $UHT = $objRecordset.Fields.Item("Tried").Value
   break }
if ($objRecordset.EOF
