Sub Main()
Dim dts As New DataSet
Dim da As New SqlDataAdapter

For example, I want to access the second cell value in "Columna". How can I do this with no using a Datagrid?

I am currently working with a datatable and I want to be able to show richtext in a column of the table. First question can this be done? I can force the column to be Type Of richtext box. However, when I try to view/display the table, I get something like..."System.Windows.Forms.RichTextbox, Text: Text That I have added" in the column.
Is there a way that I can get it to show the rich text in a cell of a datacolumn of a datatable?

The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?

I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

I have searched alot but can only find info on moving entire rows bound between 2 datagrids, but noting on moving single cells. I have some code below that works ok from DGV to textboxes but not from DGV1 to DGV2.
Dim i As Integer
i = DataGridView1.CurrentRow.Index
Form3.DataGridView1.Item(1, i).Value = DataGridView1.Item(0, i).Value

I am having problem setting focus on specific cell in my Datagridview1 . On Form1 when clicking on cell 3 in any row, I am callig a Dialog1. However, when done working with it, and closing the Dialog1, the focus returns to cell 3 in my Datagridview1 . I like to set the focus on the next cell(4) making it the current cell.
I have tryed :
DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect
DataGridView1.CurrentCell = DataGridView1.Item(4, e.RowIndex)
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells(4)
And few other things, I am always getting this exception: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

DataGridView.Rows.Item("Index of Row").Cells.Item("Name of Column").CellValue

x = DataGridView1.Rows.Item(0).Cells.Item("Dec").CellValue

am converting a old vb.net program to WPF and am having trouble. I imported some data to a datatable and dumped that into a datagrid. I now need to go row by row and extract the cell values and use them to update the appropriate database record. This was working in my old program using:
For i = 0 To DataGridView1.Rows.Count - 1
cellvalue = Me.datagrid.Items(i).Cells(8).Value).ToString
(insert to database) etc

I want to add a label in a specific cell in my table, but everything goes wrong when I do so.
I make a label and put it in column 2 row 0: table.Controls.Add(UI.createLabel("test", 9, "sans serif", "bold"), 2, 0)
That goes fine..... label "test" goes exactly where it supposed to go. But when I put it in column 2 row 1, this happens: table.Controls.Add(UI.createLabel("test", 9, "sans serif", "bold"), 2, 1)

I have a bound data grid view that is linked to a table in my Access Database.
I want to make data entry easy for the user and also error free by limiting what they can put in each cell. How can I make specific columns in my DGV have a dropdown button and add a range to it?
I know how to do it manually:
Dim NewCol As New DataGridViewComboBoxColumn
NewCol.HeaderText = "Title for Column"
NewCol.Items.AddRange("one", "two", "three")
DataGridView1.columns.add(NewCol)
But I don't want to do add each column manually...

I know this will be easy, but I can't seem to find it anywhere. How do you SET the current row in a gridview? I find tons of ways to get data from it, but I what to set a current row or cell programatically. I'm using VB 2008 express. I also find lots of promising properties like Selected... but these are all read only and i can't set them.
