Hi,

i want to know how can Rad filter generated Raddatetimepicker can be validated for proper date.


and how can message be shown for entering proper date in the Raddatetimepicker.

please reply me soon.

Hi All,
            in my application i have
one checkbox,
one button &
one RadCombobox

when we check the Checkbox & click on button ,the RadcomboBox's visible property will set to false.

& when we uncheck the Checkbox & click on button ,the RadcomboBox's visible property will set to true.

i.e radComboBox keeps appearing & dissappearing.

in this scenario i am getting the following error,

the target 'xyz' for the callback could not be found or did not implement IcallbackEventHandler.

please help me to solve this.

Thanks in advance.

I am new to asp.net programming and our team is using the latest version of telerik for our web application.
 I would like to replace the ImageUrl attribute with Telerik.Web.UI.Skins.Forest.Dock.CommandSprite.gif contained in the telerik.web.ui.dll or telerik.web.ui.skins.dll.

<asp:Image ID="dockImg" runat="server" ImageUrl="~/images/imagesCANAFTWP.jpg"  onclick="dock()"  style="cursor:pointer"/>

What is the correct way of referencing the imageUrl in the above line of markup to use?

How do I reference the active/inactive part of the image in prticular the middle set?

is there a base image to let the skinmanager "invoke" the correct color icon?

Thanks,
Michael

hello,

my pages use the RadAjaxLoadingPanel, which is cool.

however, when CSS is disabled for my pages, i think it is a bug for the animated loading-gif to visible 100% of the time at the page's bottom. 

the animated loading-gif should only be visible on the area using it, while its actively being used (based on user event).

similarly, it should not render "Loading..." at the bottom of the page all the time on text-only browsers, such as Linq.


telerik, can you address?

thanks!

I have deployed an application to a live server that is running Windows 2008R2 /64bit with IIS7. The application is installed into a virtual application directory. For deployment, I copied the Telerik.Web.UI.dll in the bin directory.

When the webform that contains date selector boxes and list box is generated, the javascript and icons do not load.  The form shows a link that says open the calendar popup where the calendar button should display.

I am using Q2 2010 SP2

Just wanted to have a discussion on the formats of the exception rule dates.
Just had a discussion about the meaning of the Z character when used within a time stamp. 

The literal "Z" is actually part of the ISO 8601 datetime standard for UTC times. When "Z" (Zulu) is tacked on the end of a time, it indicates that that time is UTC.

The dates in the exception rule section of the recurrence rule string seem to always contain the Z character indication that the time stamp is in UTC, which I`m seeing is not always accurate. I find that the date time in the exception rule is actually stored in the time zone of the machine that saved the appointment.

Can anyone at telerik comment on this at all?
Would you say that is correct from your perspective? Was this intentional?

regards,

Hi,

- I am using version 2011.1.519.35 of your ASP.NET for AJAX controls.
- I am using the Treeview with a NodeTemplate.
- In the NodeTemplate I am displaying two things:

  1. Text in an ASP Label
  2. A LinkButton that allows users to navigate to other pages in the web app.  Note that my LinkButton has NO Text Property.

I also use the OnClientNodeClicked event.  When a user clicks on the node, the javascript function executes a RadAjaxManager.ajaxRequest to load other information on the page.

I do want to run the OnClientNodeClicked javascript function when the user clicks on the Node's Text and that works.

I do NOT want to run the OnClientNodeClicked javascript function when the user clicks on the LinkButton in my NodeTemplate.

IMPORTANT:  When my LinkButton has a value set in it's Text Property, I can click on the text of the LinkButton and it does NOT run the OnClientNodeClicked

MY PROBLEM:
But when my LinkButton as NO Text property (I want to only display an image, no text) and when I click on the Image for the LinkButton, the OnClientNodeClicked function is running.

Since my LinkButton's purpose is simply to navigate the user to another page in my web app, I want to NOT run OnClientNodeClicked when they click the image because as I mentioned, it does an ajaxRequest to that same page and updates another user control there.  That is a postback I don't want since I just want to navigate to another page.

Instead of a LinkButton, I've also tried using an asp:Hyperlink control and an asp:Literal with an <a href...> that I build in server-side code.

QUESTION:
So how I can either determine that the Image in the LinkButton was clicked in the OnClientNodeClicked function and then cancel / exit that client event, or how can I set up my NodeTemplate so that the Image in the LinkButton does not fire the OnClientNodeClicked function in the first place?

My treeview is as simple as this:

 

 

  

Thanks,
Michael

I'm using RadAsyncUploader (latest version of course) to upload multiple images to a page.

However, i'm getting FielNotFoundException in the FileUploaded event all the time and
after some investigation i can see that the file is uploaded ~App_Data/RadUploadTemp with a random generated name.
Later when the program steps into the FileUploaded event it tries to find a file with another  generated name.

What makes this a bit more complicated is that sometimes the filename it tries to access is the uploaded one.

Can you assist me with this issue?

Hi, I have master child grid and export functionality in both parent as well as child grid.

Hi,

Not sure if this is the correct forum for this sort of question, but here goes:

I have a login page that uses the FormsAuthentication logic to secure the website. It is set up to disallow any access when you are not logged in (other than the login page).

That means literally every file is inaccessible, including .css files and images. Those I need on the login page, I have set up as exceptions, using the <location path="css/login.css"> setting in web.config.

Now, apparently the site's Telerik skin is not active either, so I assume I need to set it as an exception as well, but since all of that is stored within the Telerik dll, I don't know how to allow it.

Any ideas?
