ADO.NET :: Updating A Dataset Table To The Database?

Feb 22, 2011

I have an asp.net application using visual studio express 2008. On one of my pages I created a dataset from one of my database tables. I am able to delete rows and add rows to the new dataset table. I then have a button and on the click event I use the commandbuilder to update the database table. The database table updates with new rows but the deleted rows are not carried out and I can not figure out why desite spending several hours on google to resolve this issue?

Here is some of my code:

Protected Sub Button_updateDatabase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_updateDatabase.Click
Try
'I have created a session variable for my data adapter
Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter"))
Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand
Session("Adapter").DeleteCommand = commandbuilder.GetDeleteCommand
'I created a session variable for my dataset
'This update command updates new rows to my database table but not deleted rows
Session("Adapter").Update(Session("CalendarDataset"), "Name")
Catch ex As Exception
Response.Write(ex.Message)
End Try
End Sub

ADO.NET :: Convert String To Int Before Updating Database Table?

Sep 22, 2010

I have a form in which I display data from a database table, change the data and then update the database table. The form consists of textboxes, so all data displayed in the form is string. However - one data is int in the database table (the rest is varchar), so I need to convert it from string to int when I update the database table. How do I do it?

[Code]....

And, strangely enough, the same code doesn't work with parameters. How is that?:

ADO.NET :: Updating .edmx Dataset Under MVC 2

Nov 9, 2010

When I add a column to my database my .edmx is not updated when I use the 'UPDATE MODEL FROM DATABASE' context menu. No matter what I do the .edmx file is never reflective of the added column. I tried to close the project and reopen it, no luck. I closed the vwd 2010 and restarted it, no luck. I finally decided to delete and rebuild the .edmx file from scratch. This is when I finally had success of viewing the added colum in the .edmx display, even though the added colum showed all along in the Database Explorer? Could there possibly be a hotfix or something that I am missing either for SQL 2008 R2 or VS 2010 VWD?

Also my Movie.cs file which carries the 'partial call Movie' as outlined in the tutorial and the namespace Movies.Models, is not produceing the [Required(Errormsg:...)] against the Title field. When I look thru Movies.Designer.cs, I have identical namespace of Movies.Model and the class Partial Movie enties present. I am not at all sure why there is no recognition between the two modules resulting in a valid client validation check?

Asp - Updating GridView With DataSet Source

Mar 23, 2011

I am working on a page to let a user import an excel file into our database. I want to allow the user to manipulate certain fields before committing the information so I loaded a DataSet from the Excel file and bound that to a GridView.

DataSource Controls :: Updating Dataset Value To Upper Or Other Method?

Jan 13, 2010

I have a dataset where I would like to upper all string fileds and when done check each field for a value. The other way i thought to do it is to do an upper of each string when I do the conditional check. I would like to know what is quicker upper of the values in the dataset or upper in the conditional statement? Knowing the dataset will contain a max of 10.000 rows and there are multiple conditional statements in the complete process.

DataSource Controls :: Querying & Updating Data From Dataset?

Mar 15, 2010

I'm hoping someone can point me in the right direction. I will be as detailed as I can in explaining the issue;I have a dataset I have instantiated in a class file (vb.net), and fill the data succesfully. That data is then dumped into an excel file. What I need to do is to go through all the data in the dataset, and directly update the database, changing a "status" column from "pending" to "processing" based on the store number. As I am new to datasets (relatively speaking, of course), I am not quite certain how to accomplish this task. Below is the code I have so far:

If anyone could provide sample code to use, or could provide a quick bit of code I could just copy and paste in and test,

C# - Creating A List Of Dataset Fields And Form Fields For Easy Updating?

Feb 25, 2011

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:

txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();

And conversely when it's time to submit.

formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();

I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.

So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.

VS 2008 Updating Table Fails

Feb 12, 2010

why this update is failing? The table is connected to OK and there are appropriate values in the parameters to the subroutine, and yet the record in the table remains unchanged. I am using exactly the same code (with different parameters, obviously) to update another table and this continues to work fine.

Public Shared Sub SaveMathsSettingOptions(ByVal ID As Integer, ByVal Auto As String, ByVal Repeats As Integer, ByVal Weekly As String, ByVal ClassSheets As Integer, ByVal HomeSheets As Integer)
Dim con As New MySqlConnection(_connectionString)
Dim ret As String

sql = "UPDATE centres SET maths_auto = @maths_auto, maths_auto_reps = @maths_auto_reps, maths_weekly = @maths_weekly, maths_class_sheets = @maths_class_sheets, maths_home_sheets = @maths_home_sheets WHERE centreID = @centreID"
Dim cmd As New MySqlCommand(sql, con)
cmd.Parameters.AddWithValue("@maths_auto", Auto)
cmd.Parameters.AddWithValue("@maths_auto_reps", Repeats)
cmd.Parameters.AddWithValue("@maths_weekly", Weekly)
cmd.Parameters.AddWithValue("@maths_class_sheets", ClassSheets)
cmd.Parameters.AddWithValue("@maths_home_sheets", HomeSheets)

Try
con.Open()

I would like specific columns, by name or position doesnt matter.So if a column is = named column, then addcell and also, the data needs to be interpreted: If value of column = x then response.write("y")
