Table Control
I populate an asp.net table control dynamically in a button click event but it disappears after page postback. how can I keep there after the postback? I have already placed a Table in in the page instead of creating at run time and adding to a place holder.
please help

<asp:Table ID="Table1" runat="server">
</asp:Table>
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tr As TableRow = New TableRow
Dim j As Integer = 0
Do While (j < 10)
Dim tc As TableCell = New TableCell
tc.Text = "date_" & j
tr.Cells.Add(tc)
j = (j + 1)
Loop
Table1.Rows.Add(tr)
End Sub
When I click another button the table disappears.

You need to generate the table on every postback as the table state is not persisted during the postbacks.
In Button_Click save a flag in the viewstate. e.g.
ViewState["gen"]=="y";
And in the page_load check this flag, if its "y" then generate the table again else don't generate it.
