VS 2008 DataGridView: How To Show Row #'s
Feb 16, 2010
This is a simple one, but I haven't seen a way to do it. I have a DataGridView that is bound to a Sql-Server database, and it works fine. The only thing I'd like to add is the row # at the beginning of every row. Yes, I COULD set the first column as "RowNUm" and maintain it that way, but it seems that having the row # on each row should be a feature already provided to us. So, is there a way to have the DataGridView display a row number for each row?

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I'm using Visual Basic Express 2008 in Windows 7(64-Bit). I've added a datasource to my project and dragged a table from Data Sources onto my form. It automatically created a DataViewGrid and placed this statement in my form load event:
Me.BillsTableAdapter.Fill(Me.DoBills_2009DataSet.Bills)
The DataGridView shows all the correct fields/columns. The .DataSource property for the DataGridView is set to the automatically created BillsBindingSource. When I preview the BillsTableAdapter, the data appears. But data does not appear when I run the app. The datagridview is empty. When I build the app and run the executable, I get a Microsoft .NET Framework error message that says: "Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click Quit, the applicaiton will close immediately. The 'Microsoft .ACE.OELDB.12.0' provider is not registered on the local machine." If I click "Continue" I get my form with an empty DataGridView. What am I missing to get the data to display in the grid at run time? Oh, and I've also tried using the DataGridView in C# and I get the same problem.

I have a dictionary (literally) database file in Access: its Fields are Headword (string) and Definition (Memo, it's in Rich Text). The Rich text looks fine in Access, but when I connect a Visual Basic (2008) Datagridview control to the database, the text looks like HTML, not RTF, and when I try to copy a specified "definition" into a RichtextBox, I get the same weird symbols, not RTF. One attached snapshot is how a record looks in Access, the other in a VB 2008 form with a datagridview control and an attempt to paste contents into a RichTextBox.
How can I get that same "look" from the RTF in the original Access file? I'm only recently moving from VB6; not a professional

I fill the DGV by looping through a dataset and adding a DGV row for each datarow. After this the DGV.RowCount = DataSet.Rows.Count. Funny thing is that the DGV shows only a part of it (19 of 2448 in my example). After some testing I figured out that the rows show up if I change the Window size a bit.So now I use a work-around by including the following code after I've filled the DGV:[code]

I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.

I used to have a single DataGridView (DGV) on a form. I formatted and populated this, then used DGV.Show to make it appear on my form. This worked fine.I upgraded my form, to included 2 DGVs. Within a sub I dim a new DGV, populate and format it as before then set this equal to whichever DGV on the form it's meant to be. For example:
Dim pDGV as new DataGridView
with pDGV
.ColumnHeadersVisible = True

I only want specific columns to show up in my DataGridView, so I run a dynamic sql query to select specific columns from a table on a sql server(I know its slow, but its only used once a day). However, every column from the table shows up in the datagrid, and I can't figure out what i'm doing wrong.
Public Class Assign_Priorities
Dim connect As New SqlConnection("Data Source=IRNTS4SQL;Initial Catalog=Materials;Integrated Security=True")
Dim ds As New DataSet
Dim da As New SqlDataAdapter("SELECT [Priority], [Tool Type], [Lot Number], [Process], [Priority Notes], [Quantity], [Time Job Entry] from [FPAD Process Log]", connect)

As part of a user interface I'm designing, I'd like the user to encounter the following: when the user wants to edit a value in a cell, the cell in the DataGridView is replaced by a DataGridViewComboBoxCell. This is working now, however, when the user enters the cell (edit cell) the edit cursor stays there, and the combobox won't show. When the user leaves the cell, the Combobox shows, and after again entering the cell and clicking on the combobox, the dropdown finally shows. So 6 clicks are necessary, and I'd like to reduce this to a maximum of two clicks.
Using VB.Net on Visual Studio 2008, with .net 3.5
This is my code:
Public Class Functions:
Public Sub ComboBox(ByVal source As System.Windows.Forms.BindingSource, ByVal MainView As System.Windows.Forms.DataGridView, ByVal valuemember As String, ByVal displaymember As String, ByVal row As Integer, ByVal column As Integer)

I'm using a DataGridView that gets its data from table in Microsoft Access, one of the fields is a Short Time type record (e.g 16:00) but when the DataGridView is loaded it shows the record as "16:00 12/31/1899" and never shows only the ShortTime.

I had a DataGridView that was bound to a Table in my typed DataSet. I recentyl added a new column to the table in the database and updated the table in the DataSet accordingly.Now, when I go to the DataGridView to update it, the new column does not appear under the "Databound column" list. I tried setting the data source to "None", then reselecting it. Still, it does not show the new column. I then deleted the DataGridView and re-added it to the form. Again, same result. However, when I select the data source, then click "Preview Data", it show the added column.
