[Solved] PanelBar will not collapse

[Mark Mergler]

Hi

I have a data bound PanelBar that will not collapse.

This is the rendered HTML

<div id="ctl00_Main_nav1_RadPanelBar2" class="RadPanelBar RadPanelBar_mresource" style="height:300px;">
    <ul class="rpRootGroup">
        <li class="rpItem rpFirst"><a href="./" class="rpLink"><span class="rpOut"><span class="rpText">Home</span></span></a></li>
        <li class="rpItem"><a href="reporting/" class="rpLink"><span class="rpOut"><span class="rpText">Dashboard</span></span></a></li>
        <li class="rpItem"><a href="#" class="rpLink rpExpandable rpExpanded"><span class="rpOut"><span class="rpText">Reporting</span></span></a><div class="rpSlide" style="display:block;">
            <ul class="rpGroup rpLevel1 " style="display:block;">
                <li class="rpItem rpFirst"><a href="pages/c.aspx" class="rpLink"><span class="rpOut"><span class="rpText">SMS Applicants</span></span></a></li>
                <li class="rpItem"><a href="reporting/conversion/" class="rpLink"><span class="rpOut"><span class="rpText">Conversion Rate</span></span></a></li>
                <li class="rpItem"><a href="reporting/source/" class="rpLink"><span class="rpOut"><span class="rpText">Candidate Source</span></span></a></li>
                <li class="rpItem"><a href="reporting/livesms/" class="rpLink"><span class="rpOut"><span class="rpText">Live SMS</span></span></a></li>
                <li class="rpItem"><a href="reporting/poll/" class="rpLink"><span class="rpOut"><span class="rpText">Poll Results</span></span></a></li>
                <li class="rpItem rpLast"><a href="reporting/mapping/" class="rpLink"><span class="rpOut"><span class="rpText">Mapping</span></span></a></li>

            </ul>
        </div></li><li class="rpItem rpLast"><a href="#" class="rpLink rpExpandable rpExpanded"><span class="rpOut"><span class="rpText">Campaign Tools</span></span></a><div class="rpSlide" style="display:block;">
            <ul class="rpGroup rpLevel1 " style="display:block;">
                <li class="rpItem rpFirst rpLast"><a href="pages/v.aspx" class="rpLink"><span class="rpOut"><span class="rpText">Visitors</span></span></a></li>
            </ul>
        </div></li>
    </ul><input id="ctl00_Main_nav1_RadPanelBar2_ClientState" name="ctl00_Main_nav1_RadPanelBar2_ClientState" type="hidden" />
</div>

And this is the code that created it

<telerik:RadPanelBar runat="server" ID="RadPanelBar2" Height="300px"  EnableEmbeddedSkins="false" Skin="mresource"
         DataFieldID="MenuItemId" DataFieldParentID="ParentID"  >
        <DataBindings>
        <telerik:RadPanelItemBinding Depth="0"  TextField="Text"  NavigateUrlField="NavigateURL" ExpandedField="Expanded" />
        <telerik:RadPanelItemBinding Depth="1" TextField="Text" NavigateUrlField="NavigateURL"  />

        </DataBindings>
        </telerik:RadPanelBar>

 
I have created a version of the PanelBar manually entering the items and the rendered html is the same, but the expanded items collapase.

The difference that I can see is that in the databound version I pass in a NULL as the NavigateURL for the items I want to collapse where as on the static version I do not use the NavigateURL attribute at all.

Thanks

Hi Mark Mergler,

Can you try removing the NavigateUrlField="NavigateURL" from the databinding expression of the level 0:

<telerik:RadPanelItemBinding Depth="0"  TextField="Text"  ExpandedField="Expanded" />

Hi

I have investigated further and this issue seems to be due to something related to the script manager.  The PanelBar was within a control (nav.ascx) and it worked fine when it was manulalty built, ie not data bound.

When I used a datasource and did the databinding in nav.ascx.vb that is when the collapse stopped working.

I have now moved the PanelBar code from nav.ascx and put it directly onto the aspx page that the ScriptManager is declared on and it works with the data binding.

I am having the same issue with a Grid now, this is on a separate aspx page and the ScriptManager is declared on a master page.

When I bind the datasource for the Grid on the aspx.vb page the filtering etc does not work, but if I have the data source on the aspx page it does.

I'm very confused.

Hello Mark Mergler,

This is really strange.
If you could reproduce the problem in a simple project and send it to us - we will be able to inspect it locally and find the cause of the problem.
