[Solved] Slow performance with the RadPanelBar

I am using a RadPanelBar control to house a hierarchical navigation tree in one of the pages on my site. The Panel Bar has two or three levels of items, each with an associated ID, parent ID, text attribute, URL and two or three other custom attributes. I have an OnItemClick event handler to update a section of the page whenever an item is clicked (from a custom attribute named "content"). Thus clicking any item causes a post-back.

My problem is this: although the site runs smoothly on my local server, when I deploy it to a remote server I experience long delays when waiting for the screen to be updated after clicking on an item in the Panel Bar. Using Firebug to investigate, I have found that a typical page is around 125KB in size, with most of this being taken up by the Panel Bar in terms of HTML tags or ViewState contents.

Is there an optimal way to use the Rad Panel Bar in situations like this when the items are "heavy"? Can I minimise the amount of ViewState required, or compress it somehow? Are there any settings that might improve performance? Or should I be looking at moving a lot of my server-side processing to the client? Any advice would be helpful, either general or specific.

Thanks,

Ed Graham

Custom Skin RadPanelBar

Hi,

I have been stuck on an issue for a long time now and in need of some assistance.

I am currently working on a DotNetNuke module with the Telerik DLL which is being referenced. I have Telerik file version: 2008.02.0826.20.

I am trying to make a custom skin for the RadPanel Bar and followed the instructions outlined the Telerik "Basics of Telerik RAD Controls Skinning" and it doesn't seem to work.

The following is the code I am using which is nice and simple.

ASCX:

<

telerik:RadPanelBar runat="server" Width="200px" Height="450px" ID="MyMenu"

Skin="WindowsXP" ExpandMode="FullExpandedItem"

PersistStateInCookie="False" EnableEmbeddedSkins="false" >

Radgrid initialization performance problem

My user request me to turn off the paging function of the grid, but it turns out the time for the grid to initialize is quite unacceptable(over a minutes). I have read a page about this problem and it suggested to turn off all client side event of the grid, but it is not possible for me as at least the sorting function and row double click event should be kept. So do you have any other method to better the performance? (My target is to show a few hundred record in the grid with no paging)

And I am curious about something. After I use the paging function, and then I change the page side by the "footer bar" of the grid, and it turns out the performance is okay. So why? Thank you.

[Solved] Set selected value of a lot of combo

Hi

I have 8 combobox on my form.
I have to set for each of them the selected value (Radcombo.Selectedvalue="Text")

In some case the value does not exist in the combobox, so I need to set the combo.selectedvalue to nothing

Do do this I use a "Try-Catch as Exception" for each combo ! As you know Try-Catch is not good for performances.

Here my code

Try
Zlocaledit.SelectedValue = Zlocal.Text
Catch ex As Exception
Zlocaledit.SelectedIndex = Nothing
End Try

Try
ZServiceEdit.SelectedValue = Zservice.Text
Catch ex As Exception
ZServiceEdit.SelectedIndex = Nothing
End Try

Try
ZSocedit.SelectedValue = ZSoc.Text
Catch ex As Exception
ZSocedit.SelectedIndex = Nothing
End Try

Etc etc etc

Is there another way to do this ? (Without a Try-Catch)

Thanks all
