Adding Table Values In Datagridview To Database Usnig Coding?
Nov 15, 2011
here is the coding for creating a table with book name, author name, isbn , tileetc,........
in the below coding i need the insert , retrieve, and update coding as vb.net coding
DataGridView1.ColumnCount = 4
DataGridView1.ColumnHeadersVisible = True
have web page, In that I created table and loaded row values at run_time using javascriptNow I want to take a those table values in aspx.vb coding area, I tried it does not pull up my values even my table has 3 rows, but in aspx.vb area it shows row count as 0. How can I achieve this.
A new project requires that we have two servers set up to accept requests. Originally we had a reporting system which queried a database and brought back various details to the user. We now obviously need to query two database on seperate servers and merge this information to provide real-time reporting.
I have DataGridView Named EditRecordDates with column called RecDateApp. Its the 3RD Column in DataGridView--I want to take Value from Textbox called AppDateTextBox and Populate all Rowa in Column with Value
I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.
I have a DataGridView table that I allow the user to enter data into. I have a button to add a row. This works OK but how can I select that row after the button has been clicked. The reason for this is so the user will not have to scroll to the bottom of the list the enter data into the new row.
i have a datagridview and in one of the columns i m storing the amount on button click...i want to add the values of the amount at that time only i have done this but it is displaying 0 in the required textbox total += Form1.DataGridView1.Rows(counter - 1).Cells(6).Value
I am working on TreeView Control. I want to create Nodes in the Treeview. For this,I have a DataGridView1 table which is having the Data.In this table i want to use First Column Data.
In the first column data the values like 3101,3102,3103....3201,3202...3301,3302,..3401,3402..So i want to create Treeview Nodes like 31 is the Parent Node and under Parent node i want to display 3101,3102,3103..are Chiled Nodes.
I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable" Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
I am using data grid view in Windows Form standalone application to display items as excel spread sheet in VB.NET. I got a table named CostTypes with column names [CostTypeID, CostType] and values [1,External] and [2,Internal] (These are constant but more values can be added to table).
I want to create columns with names of the values[External , Internal] in DataGridView. If I use databiding directly I get columns [CostTypeID,CostType] which is not what I am looking for.
I have a datagridview that is populated from an Oracle 11g DB. What I would like to do is add the values of a column together and display the results in a textbox. What would be the easiest way to do this?
Iam trying to link a database to a website. I want the website to allow a user to make a username (OrgID) and password (OrgPassword) and have them apear in my database table (Organizer). This is the code I have so far, but I cannot get it to update the information in the database.
I have a class that represents the table of a db-row. Its properties are the columns of the table. I add a new row to the table with the following code:
Public Sub AddRow(oTestRow As TestRow) Dim sql As String With oTestRow
[Code]....
That is just an example, but my classes have around 30-40 properties and this brings a very large and complex sql string. Creating, editing or maintaining these sql strings for many classes could generate errors. I am wondering if any compact way or method exists in order to add the whole object's istance (the properties of course) to the table "TestTable" without writing such a large sql string. I created the TestRow in the way that its properties are exactly the columns of the table "TestTable" (with the same name). But I did not found in the ADO.NET anything that could be used.
I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.
I am making a application that has the ability to edit values on a access database table. As a simple example, My table looks something like this:
Order Number Completed 2000 No 2001 No 2002 No
The application needs to edit the Completed columns. I have 1 text box, and 1 button in my form. You enter the Oder Number in the textbox and press the button. The VB application then needs to change the Completed to Yes in the database. Example, I type in 2002 in the textbox and press a button. The application changes Completed to Yes for this order number in the access database and saves/updates the database.
I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.
Imports System.Data.OleDb Imports System.Exception Public Class Form11
The below code is suppose to create a database and a table with a column "FirstName" which is assigned a value "James"
Imports System.Data.SQLite Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
But for some reason the app only creates a a database which has a size of 0 bytes. Why is it not working . I am using I am using SQLite ADO.NET Provider. , VS 2010, Winforms
i apologize if this isnt up to your developer lingo, i really do lack proper developer/English skills)Just for starters this request is 100% genuine...im not some student trying to get you guys to finish my project, this is purely for educational and personal information for myself.Scenario: (brief)(i am using Visual Studio 2010)I am wanting to build a project that generates a printable purchase orders report and retreieves and save the entered details to a access Database (MDB).
In the purchase order application im trying to develop i want a user to be able to select existing clients from n table in the access DB. in which will then fill a portion of the CLIENT detail section in the application. i want to then be able to uses these client details to create a unquie purchase order ID containing all client details aswell as the purchase order list for that client this such as products and labor or whatever is inputted in the fields. (I have attached a screen shot of a brief example of the form layout, might give you more idea. - screen shot made in VISIO)

How can I search a table in a database using vb codes and display any table that match the criteria in a datagridview?? is it possible? I'm using vb 2008 and a ms sql server 2005 management studio express...
Im gettin this error when I try and insert values from my datagridview to my database: "Index was out of range. Must be non-negative and less than the size of the collection.
In the example from my book, I'm coding a button click event, and adding the code..."me.width=me.width + 20"The author states that "me refers to the object to which the code belongs(in this case the form)".
But this isn't exactly accurate, is it? The "code belongs" to the button object -- not the form object, right? So, I'm guessing that what the author really should have said is that "me refers to what ever form you're working on". Would that be true?
I need an application which opens a table from a database(in my project) in a Datagridview. Then it allows me to modify it and save the table. I managed to do all this but when I open the database in my project( with Ms Access) the data remains the same. Why is this happening?
I have all connections working and I am using this code to save:
Me.RegistrationTableAdapter.Update(Me.ContactsDataSet.Registration)I need a reply asap if it is not a problem.
I have one textbox at form named "Ord ID". I have bind database table with datagridview control and now on load event data is displaying correctly. In Datagridview there is one column which is checkbox type, suppose at datagrid there are 10 records displaying, and I have tick 6 checkbox for 6 records, so when I press add button then the value exist in textbox automatically comes to only six records of Datagridview column named "StatusID".
I am having trouble setting up an application that uses DataGridView to update the publishers table from a pubs.mdf database. And I need to make sure that all fields that might throw an exception are being validated.
