Programmatically Populate DataGridView?
Sep 25, 2010
I have a DataGridView that I'm trying to populate using a For loop:
Dim serverName As String = SQLServerName + "" + Instance
Dim server As Server = New Server(serverName)
Dim Datatable1 As New DataTable
For Each database As Database In server.Databases
Dim row As DataRow = Datatable1.NewRow
[Code]...
The DGV has been designed with the designer (columns, layout etc). Using the above the DGV does not populate. I was using a ListView for this but I need images in a subitem so have switched to using a DGV.

I have two DataGridViews in one window. The first one displays 2 columns, itemNo and taskWhen I click on a row in this grid, I want to populate the second grid with corresponding material. It is organized so that the itemNo in grid1 is 1, 2, 3, and so on, and so when a row is clicked, I want grid2 to show data that is 1.0, 1.1, 1.2, 2.0, 2.1 and so on. This data is all available in a table that exists within a dataset. However, tableAdapters do not use the .StartsWith function. I am able to get the information from grid1 when it is clicked on using Me.DataGridView1.CurrentRow.Cells(0).Value.ToString but how can I use this to get the data from the table into grid2

For my application i'm trying to generate a datagridview with a comboboxcolumn in it. This combobox I wanna fill with some data from a table in my database.I've figured out how to add items to the combobox but I can't assign a value to it. The combobox is suposed to fill with product name items, and the value should be the weight of the product, so later on i can calculate the total weight.But now it's just displaying the product name, and the value is also the product name.

I am using Visual Basic 10/I have 2 datagridview tables. The main datagridview can be edited by the user; adding/removing rows, changing data in text/combo columns, sort, etc. 2 columns from the second datagridview are a carbon copy of 2 columns from the main datagridview. I have achieved this by binding both datagridviews to a dataset. So that when I edit the main datagridview the effects are automatically replicated in the second datagridview.
Before I bound the datagridviews to the dataset I had a fully functional system to save the content of the datagridview to a text file and read it back in. This has now stopped working with the error message 'Can't edit a bound datagridview programmatically'.

I have a unbound datagridview for which i want to add a new row at the bottom when a user selects a value in the 2nd column of a 9 column DGV. The issue is that i have a default value (0.00) programmically entered into the last row once this 2nd column value is entered. When i call DGV.rows.add() it places the new row at teh top, but when the user enters or changes the last coulmn value then a new row is added at the bottom. I want my programmically added row to be at the bottom and have not found a way of doing this.
PS. What is the logic behind this different behavior on adding rows?

If have a textbox that is used to search a datagrid when a user types into it. This seems to be working properly, as the correct row is highlighted when text is entered. However, something isn't quite triggering properly because if I try to get the selected row, using dgSchedule.CurrentCell.RowIndex, it always comes up with whatever the last row that was physically clicked on, rather than the row that is actually highlighted.[code]...

I was just handed a VB.NET prototyping effort, and I'm not very experienced with VB.NET.I had to create a stored procedure which returns a self-referential table in order. Once, I completed that I wanted to get a DataGridView to show the results.
Previously, my team has been doing a lot of this via the GUI designer of VB.NET so I don't have a ton of code to describe, unfortunately.I was trying to follow their pattern which I will briefly describe here:
I have a DataGridView whose DataSource property points to a BindingSource. The BindingSource points to a DataSet. The editor for that DataSet calls a TableAdapter which gets the data from the stored procedure.
I previewed the data for the TableAdapter. The data is there. On frmMain's load the TableAdapter's Fill command is run. Not seeing anything. And my hunch is that this is way too complex a process to be correct. Or maybe not. I did a lot of Google searches before I decided to bother you fine folks.

Using SQL Server 2008 I created a Stored Procedure called MyStoreProc and it runs fine from the Management Tools.
In VB.Net 2008 I created a new dataset and a new TableAdaptor. In this table adapter I created a new Query called FillByGrid and selected the Stored Procedure. Previewed data and it previewed correctly.
On a form I created DataGridView and selected the Table Adapter from the dataset.
I ran the app and no data is shown. Visual Studio autocreated the code below and I changed it to select the the Query I just created:
Me.MyTableAdapter.FillByGrid(Me.MyDataset.MyTableAdaptor)
No data is shown on the grid so I tried the manual approach:
' Create the dataset
Dim da As New SqlDataAdapter, ds As New DataSet
Dim conn As New SqlConnection
[Code]....
Still no data shown. However stepping through the I can see that the connection is open, and "da.Fill(ds, "tbl1")" takes a little bit of time as it is running the Stored Procedure and ds table has the correct number of rows and columns. Its just not being shown on the datagrid.
Creating another table adapter in the dataset and returning data from a database table using a standard select * from table command display in the datagridview fine.

I am trying to auto populate some fields in my datagridview on my form called frmInfo.
I will try to explain what I need. The main form of my project is called frmEntry. frmEntry is mainly a data entry form only. A binding navigator is present to navigate between different record stored in the database. I want the datagridview on frmInfo to "grab" info present in the text fields of frmEntry.

I'm connecting a MS-SQL remotely with VB2008 Express.I defined two different methods - the first one is copied from my old VB6 application, which is working perfectly.In this application, the retrieved data is added to a listview control, not datagrid!
Code:
Dim myconn As ADODB.Connection
Dim MyRecSet As ADODB.Recordset
myconn = New ADODB.Connection
[code]....
The SQL query contain several table, thus I used a "*" instead for the table name- not sure this is correct?
Code:
da.Fill(ds,"*")

I have 4 arrays and each array has the data of one column.
What I am trying to do, is to populate data from each array (or make one big array and populate to datagirdview) to datagridview.
the way i did is very basic way and it takes a long time (>5 sec) to populate the data to datagridview.
My approach is:
add 4 columns to datagridview
do
datagridview.item( iRow, 1).value = arrayOne(iRow, 1).value
