Setting RadPanelBar to be fully expanded
HOW-TO
Set RadPanelBar to be fully expanded
SOLUTION
Here we will use the GetAllItems() method of the RadPanelBar. It returns a linear collection of all items regardless their place in the hierarchy.
<telerik:RadPanelBar ID="RadPanelBar1" runat="server">
<Items>
<telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">
<Items>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
<Items>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
<Items>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
</telerik:RadPanelItem>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 2">
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelItem>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 2">
</telerik:RadPanelItem>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 3">
<Items>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelItem>
<telerik:RadPanelItem runat="server" Text="Root RadPanelItem2">
<Items>
<telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelBar>
