Slight rendering issue w/ ListBox and PanelBar

[Bill O'Neil]

I have placed 2 listboxes (w/ transfer) inside a radPanelBar and when you switch the expanded item the listboxes remain on the screen during the transition and don't disappear until after the transition completes.

Not critical - but thought it was worth throwing out there in case you had a solution (or wanted to fix this in the next SP release.)

Hi Bill O'Neil,

In which browser did you observe the issue?

I tried in all browsers supported by RadListBox and RadPanelBar with the following configuration:

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" ExpandMode="SingleExpandedItem">
    <Items>
        <telerik:RadPanelItem Text="ListBoxes">
            <Items>
                <telerik:RadPanelItem>
                    <ItemTemplate>
                        <telerik:RadListBox ID="RadListBox1" runat="server" TransferToID="RadListBox2" AllowTransfer="true">
                            <ButtonSettings ShowTransfer="false" />
                            <Items>
                                <telerik:RadListBoxItem Text="item 1" />
                                <telerik:RadListBoxItem Text="item 2" />
                                <telerik:RadListBoxItem Text="item 3" />
                            </Items>
                        </telerik:RadListBox>
                        <telerik:RadListBox ID="RadListBox2" runat="server">
                        </telerik:RadListBox>
                    </ItemTemplate>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelItem>
        <telerik:RadPanelItem Text="Items">
            <Items>
                <telerik:RadPanelItem Text="Item 1"></telerik:RadPanelItem>
                <telerik:RadPanelItem Text="Item 2"></telerik:RadPanelItem>
                <telerik:RadPanelItem Text="Item 3"></telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelItem>
    </Items>
</telerik:RadPanelBar>

without success - the animation worked properly.

Could you reproduce the issue with the above markup at your side as well?

I agree. I see this too. The animation does work fine, but the list box stays visible as the PanelBar collapses behind it and then it disappears when the panel bar is fully collapsed. I copied the code directly out of this support ticket and tried it and it does the same thing. It's not a huge functional issue, but it does detract from the appearance enough that I can't really use a RadListBox on the RadPanelBar which is disappointing.

I know this thread is old, Bill if you happen to see this, did you ever find a solution?

Hello Jeff,

You can use OnClientItemCollapse and OnClientItemExnad events to set visibility of the collapsed and expanded items.

All the best,
