Hi,

the navbar always renders with a delay of up to 1 second.

Is there any way to reduce the time?

How big is the NavBar? How many items and levels?

Hi Sadat,

The navbar is not very big. Toplevel, 1 Sublevel and about 9 items in all.



There a calls for some dialogs in the navbar. If I remove the dialogs it is a bit better.

What is the best practice for the use of dialogs.
I have the feeling, that they delay the rendering in the browser.

For now it works fine and I'm hooked about the ComponentArt controls but I'm afraid if I include more dialogs, that it is getting slower.
Does it matter where I place (inside/outside of the content-table) etc.

Thanks,
Chris 

 

<ComponentArt:NavBar ID="NavBar1" 
	Width="200" CssClass="NavBar" 
	DefaultItemLookId="TopItemLook"
	SiteMapXmlFile="~/navData.xml" 
	ExpandSinglePath="true" 
	FullExpand="false" 
	CollapseDuration="50"
	ExpandDuration="50" 
	DefaultSelectedItemLookId="Level2SelectedItemLook" 
	runat="server">
	<ItemLooks>
		<ComponentArt:ItemLook LookId="TopItemLook" CssClass="TopItem" HoverCssClass="TopItemHover"

		<ComponentArt:ItemLook LookId="Level2ItemLook" CssClass="Level2Item" HoverCssClass="Level2ItemHover"
			LabelPaddingLeft="15" />
		<ComponentArt:ItemLook LookId="Level2SelectedItemLook" CssClass="Level2ItemSelected"
			HoverCssClass="Level2ItemHover" LabelPaddingLeft="15" />
	</ItemLooks>
</ComponentArt:NavBar>

Yes, dialogs can be placed anywhere in the page, and can be called from NavBar.
You can also try setting EnableViewState="false" to see if that speeds up anything.
Also make sure you are running the application in debug mode.
