I want to programatically create a new Tab with its corresponding Page View. But I am getting a really weird behavior with my tests.
Is this possible at all?

Yes. You can do that as if with any other ASP.NET control.

This is what I have so far:
Code: HTML/ASPX
<eo:TabStrip ID="TabStrip1" runat="server" ControlSkinID="None" MultiPageID="MultiPage1">
<LookItems>
<eo:TabItem Image-BackgroundRepeat="RepeatX" Image-Mode="TextBackground"
Image-SelectedUrl="00010225" Image-Url="00010222" ItemID="_Default"
LeftIcon-SelectedUrl="00010224" LeftIcon-Url="00010221"
NormalStyle-CssText="color: #606060" RightIcon-SelectedUrl="00010226"
RightIcon-Url="00010223"
SelectedStyle-CssText="color: #2f4761; font-weight: bold;">
<SubGroup OverlapDepth="8"
Style-CssText="font-family: tahoma; font-size: 8pt; background-image: url(00010220); background-repeat: repeat-x; cursor: hand;">
</SubGroup>
</eo:TabItem>
</LookItems>
<TopGroup>
<Items>
<eo:TabItem Text-Html="Themes" PageViewID="PageView1">
</eo:TabItem>
<eo:TabItem Text-Html="Desktop" PageViewID="PageView2">
</eo:TabItem>
</Items>
</TopGroup>
</eo:TabStrip>
<eo:MultiPage ID="MultiPage1" runat="server" Height="180px" Width="100%">
<eo:PageView ID="PageView2" runat="server" Width="100%">
<asp:Button ID="Button1" runat="server" Text="Button" />
</eo:PageView>
<eo:PageView ID="PageView1" runat="server" Width="100%">
<asp:Calendar ID="Calendar1" runat="server"></asp:Calendar>
</eo:PageView>
</eo:MultiPage>
<br />
<asp:LinkButton ID="openTabLinkButton" runat="server" Text="Open in new tab." OnClick="openTabLinkButton_Click" />
Code: C#
protected void openTabLinkButton_Click(object sender, EventArgs e)
{
string uidSuffix = Guid.NewGuid().ToString();
Label label = new Label();
label.ID = string.Format("label{0}", uidSuffix);
label.Text = string.Format("Dynamically generated at: {0}", DateTime.Now.ToLongTimeString());
PageView pageView = new PageView();
pageView.ID = string.Format("pageView{0}", uidSuffix);
pageView.Width = new Unit(100, UnitType.Percentage);
pageView.Controls.Add(label);
this.MultiPage1.PageViews.Add(pageView);
TabItem tabItem = new TabItem();
tabItem.Text.Html = DateTime.Now.ToShortTimeString();
tabItem.PageViewID = pageView.ID;
this.TabStrip1.TopGroup.Items.Add(tabItem);
}
I click on my Open in new tab button once and I get a new Tab with its page view. I click again, and I do get a new Tab but the Page Views get all screwed up. I start getting random results when I click on the tabs. Any Ideas?

Hi, Please see this post for more details. It's a very common code error: http://www.essentialobjects.com/Forum/Default.aspx?g=posts&t=1056The basic rule here is, while you can change a control's property and ASP.NET will keep the change for you during postbacks, ASP.NET will NOT keep any changes you made to the control tree (add/remove controls, etc) itself. Thanks

Got it... New question: do I need to keep track of what I've added? (e.g. ViewState or something like that) or is there a super elegant way to achieve this?

Unfortunately, as far as I know, none.
