Datagrid Changes Into Database?
Nov 7, 2011
I have spent the last day reading countless threads and webpages about updating a database with data entered into a datagrid.I have a datagrid with that I populate from an access database and the datagrid has 4 columns, 'Item Code','Description','Quantity' and 'Unit'.Another 3 columns ID, Division and Bid Refrence number are hidden. My aim was to use these as a unique reference so that I could update the changes made.I can show the datagrid just fine, no problems at all.

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I got a system which i want to insert, delete, update the data into my database and the data from database will be display using datagrid. The below is the coding for one of my button, delete.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Try
btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?

I am trying to update a database table from my datagrid using an event handler and ItemCommand. I manage to call the routine and everything is working fine except the text that is inserted into my database is empty. I managed to track this back to the text not being passed from my datagrids footer to the sql parameters. I tried using a string first and then passing that to the parameters but they were also empty. I am accessing the control using the following line.
sqlcmd.Parameters.Add("@GoodsDesc", SqlDbType.VarChar).Value = CType(e.Item.FindControl("txtGoodsDesc"), TextBox).Text
The control itself is defined using
<asp:TemplateColumn HeaderText="Goods Descriptions">
<ItemTemplate>
<asp:Label runat="server" ID="lblGoodsDesc" Text='<%# Eval("GoodsDesc")
[Code]....
It's like the text in the footer isnt being tied to the control before I call it.

Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.

I'm having a database, using GridView I retrieve the data into my WEB application.Then I set the rows to editable (not sure if it is fully completed) and when I edit some cells I want to update the GridView AND the database behind.When I click on 'edit' then the button is changed to update. I get some unhandled exception. I don't expect anything else since I didn't put any code in the update methods like RowCommand, RowUpdating, RowUpdated, RowDataBound.

I am currently stuck on a project where I am populating a datagrid from a series of labels and textboxes. I have that part down. Now for the part where I actually add it do the database, I am having a problem. It is actually adding everything to the database just like I want it but when it finishes adding the data from the datagridview, I am getting an error saying there are no values.
I have included the code I have been working with.
Private Sub btnsubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsubmit.Click
Dim I As Integer
For I = 0 To DataGridView1.Rows.Count - 1

I am trying updating a record. It seems like I did all the right things but I can't seem to update my database. I'm not sure if my update button is functioning as it should be.
Private Sub UpdateButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpdateButton1.Click
Dim cb As New OleDb.OleDbCommandBuilder(da5)
While count5 < MaxRecords5
cells5 = 0

Whenever I edit the datagrid, and press update, it doesn't really update the database.

I'm creating an admin application that will allow specific users to manage users login credentials for an application. On a form I have a datagrid that is populated by selecting * from Operator table on the DB. I want the admin users to be able to add, edit and delete records from the datagrid and i have enabled these properties on the grid but any changes need to be confirmed by clicking a 'Saves Changes' button. Here's the code behind this button:
vb
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Const cSUBNAME As String = "btnSave_Click"
Try[code].....
I have added a new record but when I save these changes I am getting this error: "02/12/2011 11:43:56,frmOperator,btnSave_Click,5,Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information."

I'm at the moment busy with a project for school. Well I have a datagridview that displays all of the employees within the company. But I want to be able to change, delete or add new employees in the datagridview and then save it in the actual database. I used this code to do that.
Me.Validate()
Me.TblPersonnelBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.DtsPersonnel)
But when I run my program and click on the save button I get this error message:
Application Exception was unhandled
TableAdapterManager contains no connection information. Set each TableAdapterManager TableAdapter property to a valid TableAdapter instance.How can I get around this? I think it has to do that my dataset exists out of 1 table but actually it contains items from 2 tables. Would this be the problem?I need to have the dataset like that though otherwise other parts of the program won't work.
