i have radpanelbar then items then radpanelitem then item then radpanelitem then itemtemplate . then inside this itemtemplate, i have an asp user control and this control is invisble. i could make it visible by doing this
document.getElementById('btnNext').style.visibility='visible';
but this is just regular html <input>. if i do this with user control like <asp:button> it doesn't work. could someone help? Thank you.

Hello Duy,
The FindControl method provides you with a reference to any control inside any of the templates used in the RadPanelBar or any of its PanelItems. You have to make sure that you properly typecast the returned value as FindControl returns a reference to a Control class. After you get the reference you may modify any properties of the referenced control.
For details on the matter please take a look at this example.

and if if i make everything htlm control, i can't seems to retreive the value
like this
Dim str2 As String = DirectCast(RadPanelBar1.FindItemByValue("hleeee").("txtFileNameSaveas"), HtmlTextArea).Value.ToString
the error is because it ocudln't find the control since it is html input now not asp control anymore.

Hello Duy,
We are a bit confused by your questions. Are you trying to access the templated control client-side or on the server? Once you are pasting here some JavaScript lines, but now we see VB.NET code-behind. Please try to be more specific on what exactly you are trying to achieve.

i tried to follow your example but it didn't work with javascript. for some reason it kept saying that the control is undefined. So i turned around and tried to use server side but was also successfull. so this is what i did right now. i made the page reload when you click on the button to display asp user controls. then i also put in an ajaxupdate so the users will not really see the page getting reload. that is what i have right now. i know this is not the best way but until i find the answer to my question i have to use that method. hope this clarifies a bit. thank you for your help.

Hi Duy,
Unfortunately, the provided information does not help us much in reproducing the error. I'm afraid we could not be of much help unless we reproduce the issue on our side. It will be best if you can open a support ticket and send us a simple running project (incl. your custom skin, CSS, images, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
Thanks beforehand for your patience and cooperation,
Paul
