unknown server tag

I've got this error message Unknown server tag 'radP:RadPanelBar' Then I have found this link http://www.telerik.com/community/forums/aspnet-ajax/panelbar/unknown-server-tag-telerik-radpanelbar.aspx for this saying that 2008 version is needed for RadPanelBar. but I have Q 2007 RadControls version.. First of all, is this really true that I need to have this version otherwise with 2007 it doesnt work? Is that anyway I can download this for free since I have 2007 version?
One thing makes me confused though if I really need to have 2008 version , why under the folder Q 2007 RadControls , RadPanelBar dll and documents etc comes with it, that's why I automatically thought that I am ok to use Radpanelbar... Please advice!!

[Solved] Missing Zeros

I am doing a cross-page post using something similar to this...

Dim

amount As RadNumericTextBox = Me.PreviousPage.FindControl("txAmount")

If the end-user types in an amount, such as 12.50 on the original page, the cross page post will drop the 0.

How can i retain the zero buring a cross-page post?

In Built Loading Panel

Hello,

It seems the latest version of the telerik controls has an in-built loading panel, which is very nice... but I was wondering if each control now has an API to show or hide that loading panel? Is that a CSS thing, or something else?

Thanks.

RadSlider not starting with minimum and maximum values selected

Hi.

I have placed 4 RadSliders on my page and am struggling to get the RadSlider selection to start at the left and end at the right of the RadSlider. See attachment below. The first slider starts about 3mm from the left and ends 3mm from the right. This seems to happen if there are less than about 5 selections to choose from. The other 3 have alot more than 5 available selections and start/end in the expected place. Do you know why this may be happening and how it can be resolved?

Thank you for your time.

Best Method For Sending RadConfirm Response To CodeBehind

I would like to have a radconfirm message on my aspx page, and depending on the answer, would like to do some server-side code.
I have found many, many different forums with multiple solutions for how to implement this logic. I could probably piece something together from what I have found, but I was curious as to the Best practices. I have never really had to communicate between client side and server side like this, so I really don't know what advantages/disadvantages there are to various methods. Would someone be able to "wrap it all up" for me in once post?

My requirements are as follows:
Situation One:
I have a Linkbutton to "Clear". When the user clicks this, I pop up a radConfirm asking them if they are sure. If they answer No, then I do nothing more. If they answer Yes, then I need to run some server-side code. I thought in this situation I would have my "CallBack" function from the radconfirm check the yes/no answer, and if yes, then call some server-side code, otherwise do nothing. Does this sound like a logical method? Best way to call some server-side code from this javascript callback function?

Situation Two:
I have a "Clear" linkbutton inside of a repeater. This linkbutton has a CommandArgument bound to an ID, and I am using a CommandName; when clicked, I "delete" based on the specific ID. Simple enough. Now they want to add a "confirm" prompt to this process, and I would like to use radConfirm for this. I would thing the process I have identified above would be okay, but how would I pass my desired bound ID to my callback function - can I just pass this into the parameter of the callback function?

Thanks for the help!
Stacey
