hi Totto,
from your code it looks like you are adding the controls directly into the
Repeater controls collection, i don't think this is correct. you may have
intended to insert the control into the relevant item:
repFylleknapper.Items[i].Controls.Add(...)
it may be easier to have your buttons declared in the ItemTemplate/aspx of
the Repeater control. this is because the Repeater viewstate will preserve
the values this way. if you do it this way, you will only need to bind the
datasource for the first page_load (if you do manual databinding).
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text='<%# Eval("ID") %>'
Tooltip='<%# Eval("Country") %>' OnClick="RepeaterButtonClick" />
</ItemTemplate>
</asp:Repeater>
i presume the previous values you refer to are in textboxes also in the
repeater? if you are inserting these the same way as the buttons, i
wouldn't be surprised that they get lost :)
my original advice to recreate the controls manually for every postback is
only valid when the controls are created programatically and excluded from
the page viewstate management. it isn't necessary if you use my suggestion
above.
when using Server.Transfer you can choose to preserve the Form values with a
second boolean parameter. does this solve it for you?
if you could describe what your code in more detail it would be helpful,
i.e. what do you do in the click event handler, and then what do you do
after the server.transfer.

Hi tim,
I found that the Repeater.Controls.Add() function was a nice way to add
buttons to the repeater, that way I can set all the properties of the
button before is's added to the repeater.
Button btn = new Button();
btn.ID = i.ToString();
btn.Click += FyllingsKnapp_Click;
btn.Text = row[0].ToString();
btn.ToolTip = row[1].ToString();
repFylleknapper.Controls.Add(btn);
But I have one problem:
I have used context to transfere values between pages with
Server.Transfere(), but when I press one of the buttons in the Repeater,
there is a postback performed. And when I come to the clickeventhandler
for the buttons, all the previus values is gone exept for the button
values because its's reloaded during postback.
Any suggestions?
I have also posted the question in another thread.
Thanks Totto

>hi totto,
that's what i would use. the repeater is the most light-weight, so it is
the fastest to use when you don't need all the grid functionality, and it
generates no HTML markup except what you specify. it should work if you
declare the OnClick event handler in the repeater itemtemplate for the
button. make sure your event handler is marked Public.
if your events aren't firing, post your code here and i'll take a look at
it. dynamic controls can be difficult to get your head around at first,
because of the postback life-cycle.
