VS 2010 Fill A Datagridview With Data From A SQL Database?
Nov 29, 2011
I am trying to fill a datagridview with data from a SQL database.The dgv will print rows and values where each row is a different category.
[VB CODE] Private Sub populatedgv1()
'setup temptable to store Server data
Dim m_table As New DataTable
[code]....
Why does it only print all the rows for each DS (different sizes/colors) only if there are more then one DS? (if there is only 1 DS it will only print one row, regardless of different colors/sizes but if there is 2 DS, it will print all the values from the first DS)I have gotten a massive headache from trying to figure out these 2 problems. If any1 can help I would be very grateful. Please let me know if you need anymore info (SQL tables, data), and I'll put them up.
I have Access database that I am connecting to as such:
Public dbE As DAO.DBEngine Public db As DAO.Database Public sql As String

1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )
I am trying to fill a label with data, using datagridview, from a specific row, cell. The commented out code works but is tedious and sequential, basically has to go row by row. Is there a way I can just say "hey, gimmee the data at x,y?" LOL Trust me, at one point I even tried that. All this must take place at form load so there is no click events involved.
Private Sub STAPLES_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.STAPLETableAdapter.Fill(Me.FSC_DATADataSet.STAPLE) [b]'THIS WORKS SEQUENTIALLY[/b] 'Me.TextBox1.Text = Me.STAPLEDataGridView.CurrentRow.Cells(0).Value.ToString.Trim 'Me.TextBox1A.Text = Me.STAPLEDataGridView.CurrentRow.Cells(1).Value.ToString.Trim [Code] .....
fill a NEW DataSet's DataTable with data from a DataGridView? I am generating a data report that uses that "new DataSet." I need to go from a DataGridView to a DataSet because i need the person to be able to perhaps edit the information before its inserted into the report. my process to generate the report is...
- fill datagridview with advanced join sql - allow user to edit datagrid if necessary - put datagrids modified information in new dataset - set report's databinding source to new dataset - generate report...
The second line will have numbers if other table has information about that customer reservations, or will be in 0 if not.I can load the first line of each pair, with the data of the "requested" items loading a datagrid with a datatable.

I just want to display data of a single column from an oracle table into a datagridview or a listbox for readonly with no requirements to make changes to it. Simply display the information.What is the best way forward... To used DATAADAPTER or DATAREADER.s DATAGRIDVIEW SLOWER TO FILL THAN a LISTBOX.i am using the following code to fill datatgridview but for some odd reasons at time it is slow to display the data. I want to use listbox instead
Dim ds As New DataSet Dim adp As OracleDataAdapter adp = New OracleDataAdapter("select customer_name from customers")
What I want to happen is that the button from my system will remove the previous data from database and then insert new data to database from text file. Im done with inserting new data. The thing is that I dont how to control or where to put the Delete Command from my code.

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold.

Im new to vb.net and would like to know the very basics on how a datagridview works? how does it populate data from the database? what process does vb follow to update this datagridview? I'm trying to get my head around the following terms and need some explaining how they work and how they are linked? if possible, is there a link to a diagram that explains this?
i know how to write a code to display data from the database into a datagridview, and i know how to use text boxs for uplying chnages on the database and directly display them in the datagridview, but what i want is to be able to aply changes without using textbox but directly the datagridview, so the user will be able to see that data on the datagriedview and insert his data in its field and update other and when he saves it will directly effect the database.
I want to fetch some data from the database to the DataGridView,so i did this
Dim connString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Etech.mdb" Dim myConnection As OleDbConnection = New OleDbConnection myConnection.ConnectionString = connString
