Hello,

We've been having an issue where users are seeing the upload button within the Upload Dialog of the Image Manager Dialog appears as text with a dashed border around it. I do not know if the button is disabled or not or even if it is functional as a button.

However it is appearing as not a button.

Any ideas on why this may be happening?

Thanks,
Cameron

PS. We are using the 2011.3.1305.40 version of the controls.

I am able to use this method in asp.net grids but am switching over  to radgrids in new projects.  What happens is that when I click on it it should just open the email, but with the radgird it also wants to try to navigate to the email to as well.  How can I just use it as a way to open the ema il of your computer.

I have a RadGrid that I have over a million records on. Currently I use a select * to display everything in the grid, so people can click next, put in a search in the filter, etc.It otherwise works perfect for me.

Under heavy load, I was wondering if there is a more efficient way to use the RadGrid, so instead of doing a select * for all the records, I can select 20 records, but still have the filters on top and the search capacity to search all million records if someone does it at the top. 

Thanks!

Hi,

I have a solution that adds tabs and page views dynamically, then based on postback criteria may potentially remove those tabs and add new ones.

The sequence is:
- First Render:
    - Build Tab with PageViewID set
    - Build PageView using known PageViewID
    - Add control to PageView
    - Add PageView to MultiPageView
- Postback (no changes of tab):
    - Find PageView and Add Control
(all working fine so far no matter how many postbacks)
- Postback (changes to tabs):
    - Find PageView
    - Find Tab
    - Remove Tab
    - Remove PageView
    - Perform sequence as per First Render except with different Tab and PageView

Then during this postback there is some code changing tab selection. This code sets  this.{Tab}.Selected = true;
An exception is thrown at this point from the Telerik libraries. 

System.NullReferenceException occurred
  Message=Object reference not set to an instance of an object.
  Source=Telerik.Web.UI
  StackTrace:
       at Telerik.Web.UI.ControlItem.get_Index()
       at Telerik.Web.UI.RadTab.set_Selected(Boolean value)

I have tried when adding +/ removing to change the SelectIndex of the RadTabStrip. I have tried selecting another (known to exist) tab. some general stuff like:

if

(tabStrip.Tabs.Count > 1)

{

    tabStrip.Tabs[0].Selected = true;

    tabStrip.Tabs[0].PageView.Selected = true;

}

Nothing I have tried is preventing this exception. I have not seen any demo or example of adding then removing + adding during page life cycles.

The other question I have is why do the RadTabStrip and MultiPageView recreate the dynamic tabs. This is not like normal ASP.NET controls which you must recreate every postback in the same order. Is there a way to prevent automatic recreation of tabs?

Thanks.

I found an exmaple here How print Radgrid, but only print current page.
I need print whole RadGrid.
how I can you this?

thanks

my radajaxManager:

<telerik:AjaxSetting AjaxControlID="imgPrint">
                            <UpdatedControls>
                                                   <telerik:AjaxUpdatedControl ControlID="pnlBellMaintainanceServices" />                              
                            </UpdatedControls>
                        </telerik:AjaxSetting>

Hi,
I am using Visual Studio 2008 and Telerik Controls Version 2009.3.1103.20.

I am developing ASP.Net Website.

I have so many different WebPages and I want to implement AJAX on my page so that I can display rotating image during postback when system is processing something.

I tried code from Telerik Demo, tried using "telerik:RadAjaxPanel" and also tried to add ajaxsettings using "telerik:RadAjaxManager" but somehow I always ended up having javascript errors on some controls. So finally I thought to post my question here for help.

I am PASTING html for my sample UI. Can you please help me what is the best way to implement this on this page?

In the attached sample HTML, I removed all of my events and other source code and just putting my basic UI design with minimum fields.

My purpose is to know hot to implement AJAX on these pages.
Please provide me working setting for AJAX on these pages as I have already tried so many different options.

I HAVE SAMPLE PROJECT BUT DONT KNOW HOW TO UPLOAD IT HERE. SO I AM PASTING ONE OF MY PAGE CODE HERE. IF THERE IS ANY WAY TO UPLOAD .ZIP FILE WITH NEW THREAD, PLEASE DO LET ME KNOW AND I WILL UPLOAD MY SAMPLE PROJECT.

Can you help me with these items? -->
 1. is it possible to display loadingpanel image for whole page and its ok to refresh whole page if we can display loading image during postback
 2. in general, for grid, whenever any paging number is clicked, it should display loadingpanel for grid
 3. CompletedRequestsDetail.aspx
           --> When "btnUpdateGeneratedPONo" or "btnCompleteRequest" is clicked which is inside ItemTemplate, it should display loadingpanel for grid
           --> when "btnViewAllSelected" or "btnViewAllSelectedSupplierCopy" is clicked, it should display loadingpanel for whole page


Thanks in advance,
Nirav
