Visibility of selectedindex of a datagriditem

I put a datagrid in a panel with an overflow set on auto.
I want to show just 5 items in the grid.

My question is how to make sure that the selecteditem is always visible in
the grid. Because now i have this situation that after each selection (I use
the itemcommand) the grid starts from the top.
when i (for example) set selectedindex = 8, the selection is made, but not
visible to me. I have to scroll down first.

Hi Richard,

I think this will do what you want.

**** Panel and grid
<asp:Panel id="Panel1" runat="server" Height="100px" style="OVERFLOW: auto">
<asp:DataGrid id="DataGrid1" runat="server">
<Columns>
<asp:ButtonColumn Text="Select"
CommandName="Select"></asp:ButtonColumn>
</Columns>
</asp:DataGrid>
</asp:Panel>

**** Code
Private Sub DataGrid1_SelectedIndexChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles DataGrid1.SelectedIndexChanged

Dim s As String = "<script language='javascript'>
document.all('DataGrid1_tr_" & DataGrid1.SelectedIndex &
"').scrollIntoView(); </script>"

RegisterStartupScript("DataGrid1_SelectedIndexChanged", s)
End Sub


Private Sub DataGrid1_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles
DataGrid1.ItemDataBound

Dim tr As DataGridItem
tr = e.Item
tr.Attributes.Add("id", "DataGrid1_tr_" & e.Item.ItemIndex)
End Sub


Does this answer your question?
