[Solved] PanelBar expand bug

[Dmitry]

Hello! Thx for your MVC components, they are great!

But, I've noticed some strange behavior when using PanelBar items content() method in some other content() method(for example tabstrip content). When the page is loaded - the state of the panel item is not expanded, but if insted of content i use item it works as it should

here is code sample

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<% Html.Telerik().TabStrip().Name("MyTabs")
       .Items(tabstrip =>
                {
                    tabstrip.Add()
                        .Text("test")
                        .Content(() =>
                        {
                            Html.Telerik().PanelBar()
                                .Name("catalog")
                                .Items(item=>
                                {
                                    item.Add()
                                        .Text("my_groups")
                                        .ImageUrl("~/Content/Img/GridTab/groups.png")
                                        .ImageHtmlAttributes(new { alt = "My Groups Icon" })
                                        // using items - that expands fine
                                        //.Items( subItem=>{ subItem.Add().Text("Test").Action("test","test");})
                                        // using content() - that doesn't
                                        .Content(() =>
                                        {
                                            %>
                                            <ul class="t-group">
                                                <li class="t-item t-state-default">
                                                    <a class="t-link" href="/MyTest/Test">Test</a>
                                                </li>
                                            </ul>
                                            <%
                                        })
                                        .Expanded(true);
                                }).Render();

                            });
                })
       .SelectedIndex(0)
       .Render(); %>
</asp:Content>

And one more thing i've noticed.

when i use content() method the inner html is located in the <div class="t-content"> tag. if i use items - the content is located right in to the <ul>. so i tried to write smth like that

.Content(() =>
{
    %>
    </div>
    <ul class="t-group">
        <li class="t-item t-state-default">
            <a class="t-link" href="/MyTest/Test">Test</a>
        </li>
    </ul>
    <div>
    <%
})

insted of

 

.Content(() =>
{
    %>
    <ul class="t-group">
        <li class="t-item t-state-default">
            <a class="t-link" href="/MyTest/Test">Test</a>
        </li>
    </ul>
    <%
})

that began to work somehow fine.

so there is something about that div or it's class or how it is processed by the script.

hope it would be helpful for you.

thx!

Hello Dmitry,

Indeed, this behavior is by design -- we strive to leave all user content in tact, and to suppress all of our code within it. If the hack that you found works for you, you may use it, yet it is not officially supported (i.e. if something goes wrong). That said, why not use the .Items method?

Hi!!!Thx for the answer!!

but....

but...but...

"By design" it's not the good answer for me =(, becuase if you allow using such html you should process it correctly.

Items method is very good, but in Q2 the selection remained on the item, that was thr reason to explore some other ways.

Po moemy u vas tam mnogo russkih

Nu esli net, to i bog s nim.

Smisl moegp obrashenia v tom chto esli uj vi predostavlyaete vozmoznost renderit svoi html v kontrolah, to sdelaite eto universalnym!

To chto ya seicas opisal eto - bug, a ne "by design"

Esli eto by design, to opishite kakie konstrukcii forbidden dlya telerik

And the last one.

Why dont you particapate in platforma 2011 in russsia. our components are great and ifyou particapet and my boss will see you may be he will give me money to buy full version of your components
