I have a csv importroutine which imports my CSV values into Sitecore. After this proces is done i want to show the errors in an asp:literal. This is not working, and I think this is because i need an updatepanel for this in order to be able to
update text after the first postback (the csv upload / import).
I made this:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
and coded this:
string melding = string.Format("Er zijn {0} objecten geïmporteerd.{1}", nrOfItemsImported, errors);
ViewState["Melding"] = melding;
And i have a button. On the onclick of this button I have:
Literal literal = new Literal();
literal.Text = (string)ViewState["Melding"];
literal.ID = DateTime.Now.Ticks.ToString();
UpdatePanel1.ContentTemplateContainer.Controls.Add(literal);
PlaceHolder1.Controls.Add(literal);
When i now press the button i want to
update the panel so that it will show my Literal with the errormsg on it. This however isn't happening. How can this be? I'm guessing it has something to do with my viewstate, i don't see keys on the viewstate after I press the button...
