are you adding a boundColumn at runtime ?
What exactly is the control you are adding at runtime. If its a BoundColumn,
it already exposes various header/item/footer style properties which you can
use for formatting . .look in the BoundColumn Members section

I add a Buttoncolumn, allthough I rather add a button with a text on it.
This column is bound to the dataset. And for the other columns I add
Boundcolumns, but the do not look good.
Text is wrapped up (several lines) and I cannot set the with of a column.
Do you have any suggestions (and/or additional reading)
Thanks

boundcolumn1.ItemStyle.Wrap = True
sets wrapping for all item cells of the column

Perfect !
When the previous button works in the datagrid then this control would be
very usefull.
Next is still possible, but previous canbe pushed after 1 or more next (>),
buto does not change the rows which are displayes and is then disabled
(allthough I pushed several time on next)

almost forgot, for the width do :
boundcolumn1.ItemStyle.Width = Unit.Pixel(100)
boundcolumn1.ItemStyle.Width = Unit.Pixel(100)

This last one is probably a bug in your application. I suggest you try and
run in debug mode again and step through this line by line and see the
execution of your code and what happens as you hit the next or previous
buttons.
The previous button should be able to go all the way to the first page and
then stay disabled if its the first page, and the next button should be able
to go to the last record and then disable on the last. Try and use numbered
links and see if your getting the same behavior whereas to next-previous
links. That is set pager mode to NumericPages whereas to NextPrev.
From your previous posts i've noted that you are doing this correctly and
are also using the OnPageIndexChanged method correctly, so surely you have a
small bug in your code.

I will do what you suggest.
In the mean time I'm trying to handle the event of the buttoncolumn. I
receive the event, but I want to get the ID of the row:
col = New ButtonColumn '' BoundColumn
col.HeaderText = "ID"
col.DataTextField = "ID"
col.ButtonType = ButtonColumnType.PushButton
col.HeaderStyle.Wrap = False
col.CommandName = "Card"
Datagrid.Columns.Add(col)
AddHandler Datagrid.ItemCommand, AddressOf Me.DataGridCard
----
the datagridcard procedure
Private Sub DataGridCard(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs)
Dim datagrid As DataGrid, x As Label
datagrid = CType(sender, DataGrid)
x = FindControl("X")
datagrid.EditItemIndex = e.Item.ItemIndex
x.Text = "Xpage " + CStr(e.CommandName) + " " & e.Item.ItemIndex &
e.CommandArgument ''DataItem
datagrid.DataBind()
End Sub
Since the buttoncolumn displays the recordnumber I want to get that ID. With
that ID i can call my dialog to edit the cardrecord.
How do I get there. The datagrid.edititemindex only modifies the way the
record is shown (an you may edit it), buto that's not what I want to do,
Thanks

allthough I have an event firing on:
AddHandler Datagrid.PageIndexChanged, AddressOf Me.nextprev
The debugmode only enters the next buton, when clicking previous, the
NextPrev event is not called ?
Private Sub nextprev(ByVal sender As Object, ByVal e As
DataGridPageChangedEventArgs)
Dim datagrid As DataGrid, x As Label
datagrid = CType(sender, DataGrid)
datagrid.CurrentPageIndex = e.NewPageIndex
datagrid.DataBind()

the onitemcommand is the right place for this. however try Try :
dim MyButton as string
MyButton = CType(e.CommandSource, Button).CommandName
Not sure where you are stuck, are you saying your unable to retrieve what
you stored in the buttons commandName, and commandArugment values or your
not able to get the cell where this button is located

MyButton = CType(e.CommandSource, Button).CommandName

dim but as Button
but = CType(e.CommandSource, Button) ''.CommandName
x.Text = "Xpage " + but.Text
the but.text gives the text on the button which is the recordid. (Offcourse
I rather do not like to show the recordid, but for now it works.)
Thanx,
Now the prev and it begins to look at a sophisticated control.

well dont store it in text, store it in commandName, its there for this
purpose. Yeah these little bugs are hard to trace, try the numeric buttons
and see if you still have the same problem.

this works, but when I push the next button the procedure DataGridCard is
also handled:
So the nextprev button fires (only the next button) via:
AddHandler Datagrid.PageIndexChanged, AddressOf Me.nextprev
but the datagridcard procedure is fired first. Via
AddHandler Datagrid.ItemCommand, AddressOf Me.DataGridCard
Probaly handlers the next also the itemcommand, but why should it come
first?

but how can i store this property in the commandname, it is a buttoncolumn,
which is databind:
col = New ButtonColumn '' BoundColumn
col.HeaderText = "ID"
col.DataTextField = "ID"
col.ButtonType = ButtonColumnType.PushButton
col.HeaderStyle.Wrap = False
col.CommandName = "Card"
col.ItemStyle.Wrap = False
col.ItemStyle.HorizontalAlign = HorizontalAlign.Center
col.ItemStyle.Width = Unit.Pixel(80)
Datagrid.Columns.Add(col)
AddHandler Datagrid.ItemCommand, AddressOf Me.DataGridCard
My commandname card does not mean anything, but how can I get the
columnvalue of the dataset.

The buttonColumn has a CommandName property. Set your text value here
instead of the doing it in the buttons text property because this will
display as caption.

i do not understand what you mean.

I think I've solved it. I add the button in unbound mode, add a second
boundcolumn for the ID column, which visible property = False. Via the cell
text property
e.Item.Cells(1).Text I receive the not visible ID
Thanx Alessandro, you helped me very good !!

yep, using an invisible boundcolumn for the id is widely used and is much
better. Good job

In the prev/next page I do not get any progressing. I'show the code:
I've changed several properties, such as
allowpaging=true, allow custompaging=true and the vitualpagingcount=100
in the control creation I added 2 button (prev en next) and they where
"redirected" to this procedure:
Private Sub PrevNext(ByVal sender As Object, ByVal e As System.EventArgs)
Dim But As New Button, a As String, b As String
Dim datagrid As DataGrid, x As Label
But = CType(sender, Button)
a = But.CommandName
datagrid = FindControl("GRID" + ClientID)
If But.CommandName = "next" Then
datagrid.CurrentPageIndex = datagrid.CurrentPageIndex + 1
ElseIf But.CommandName = "prev" Then
datagrid.CurrentPageIndex = datagrid.CurrentPageIndex - 1
End If
datagrid.DataBind()
End Sub
Nothing happend, allthough in debug mode I can see that the currentpageindex
is modified
