Hi,
I know I have the bad habit to put myself in complicated situations...., but it is not my fault, blame my customers ;-)

The Situation is as follows:
I have a Content Page which has as Master Page. Inside the content Page I load several User Controls. From one of the User Controls, which contains a RadGrid, I open a PopUp to edit the detail of the Grid. The PopUp contains a Button to save the detail and after saving I call a javascript function inside the Content Page (...actually inside the User Control) that triggers a AjaxCall to Rebind the Grid.
Everything works fine....only the first Time !!! 
After that the debugger of Firefox tells me that the RadAjax Manager does not exists. I have to reload the Content Page (not even the User Control) to have the Rebind working again.
I'm pasting here some code.

The Master Page has nothing special inside it besides a Beside that only HTML and CSS.


The Content Page:

...and the code to load the controls.



The User Control.

The Rebind javascript is to Rebind the RadGrid. The code behind just says:



The PopUp that is opened by the User Control:

..and the code behind to Update and trigger the Rebind.

So, to make a long story short, First Rebind ....works great...and then non more Rebind till Content Page full reload.

Any ideas ?
Thanks much as always.

Hello

    I am using Radchart in a usercontrol for one of our application. The version of Telerik I have is 2012.1.215.40. I have Windows7 OS and IIS7. I have required Web.config entries in both System.Web and System.WebServer (Actually the entries were generated by the smarttag "Add RadChart HTTP Handler to Web.Config" option).

    The radchart shows up fine for the first time. When i click the same page from the menu, the rad chart shows up a popup "Error loading RadChart image"

  I tried the suggestions given by Evgenia in this post . Even setting usesession=false and setting the temp folder property resulting in the same sequence, first time it loads properly and second time when I load the page again it shows the error popup.

  Please help

Thanks

Hello,

Can someone explain or point me to a tutorial where I can have multiple windows nested in a tab strip.....with separate executing domains. So I guess what I'm asking is if there is a way to have one window nested in one tab using Chrome and the other tab/window using IE or Firefox?


So I might not be using the terms exactly correct so let me explain. I would like to have the tab strip with different tabs and the windows in that tab kept separate.

So user loads the default page and it has two buttons. New Tab Secured & New Tab Unsecured. The tab strip would be bound to an object and clicking either of the buttons would add another element to the collection so the tab strip would update with the new tab.

New Tab Secure would pop a modal window asking for credentials and a tab nickname (optional). Once entered it would go to an internal intranet site and the window of that tab would display the web page with the user logged in.

Now here is the trick that I am really unsure of.

New Tab Unsecure would open a new tab to the same site but of course we DON'T want the user logged in. PROBLEM. If for example IE is used then UNSECURED will be reading from the same cookies etc. and it will use the user credentials.

What I am desiring to provide to users of the system is the ability for them in one tab to have a administration login to make crud changes to the site. In the other tab see the impact of those CRUD operations.

Thank You

hi,
the parent is a sharepoint page, which has a webpart user control, which contains an iframe, which contains a user control that holds a radgrid control.
the radgrid has sorting filtering and paging enabled, i am using simple databinding and everything seems to work fine except the paging. lets say i have |<   <  1 2 3 4 5 >  >|   when i click on 2, the page posts back and the 2nd page is shown correctly and the number 2 is higlighted and same is the case with 3 and 4, however when i click on 1 (when the current page is 2) , both 1 and 2 are highlighted, the page does a postback but the contents are still of page 2, the next and previous arrows also exhibit the same behaviour. i am using the Black Skin and 2009.1.402.20 version., no matter what i try to do i cannot go back to page 1. this is the same behaviour in IE and FF

i have been reading couple of other threads which recommend using advanced databinding using needdatasource, i have tried that, but strangely the needdatasource method is not getting invoked automatically, the grid is blank.
when using the simple databinding i called the ShowListings() method from page_init(), but i commented those lines, because of the needdatasource method.

please advise.

here is my source code

Hi ,

Using Telerik Ajax Q2 2009 

Using a rad window manager,  if I open a rad window and minimize it and then open another Rad window,  and then  I maximize the first Rad window the maximized window will be in the back and the second Rad window will be on top. 

I believe the issue is related to the z-Index of the maximized window,  is there a way to alter the z-index to set it to a highest number so it will open on top

Sincerely,

Fadi

Hello,
I have a radbutton with the buttontype of Togglebutton and would like the font size to change when the button is toggled - a larger font when it is selected and a smaller font when it is not.  I am trying to do this through a Css Class.  It seems like everything else works just fine - I can change the font family, font weight, background color, etc., but the font-size does not.  Please help.

Thanks.

How can I close a radwindow from within a multipage pageview contenturl content page.
