Hello,

I'm using the ASP.NET AJAX pageLoad()-method inside my javascript to attach e.g. a click event to a task of the gantt control. But it seems that this pageLoad()-method will not be invoked anymore if I collapse a task. And even if I expand that task again, the pageLoad()-method inside my javascript-code is not called anymore, too. The $(document).ready()-function is not working in my case because I add a special css-class as a bookmark to attach the click-event and this must happen on every page load. I hope you can help me.

Regards,
Felix

Hello

For several year that I'm using Load on Demand based on XML. I start notice some failures lately and I saw that the fastest way is using a Web Service. Can I build new nodes calling a Web Service and change the node image?

When I am trying to brows Asp.netAjax live demo in my machine it displays error message: the error is like this
A network-related or instance-specific error occured while establishing a connection to SQL server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL server is configured to allow remote connections.  (Provider:SQL Network Interface, error: 26-Error locating server/Instance specified)

Is there any means to fix this problem?

I have a radscheduler and the date that shows up in the header is very dark.  I have used other radschedulers in my application and did not have this problem, so I have to believe that it is something I did with this specific one.  I have attached a screenshot of the code for the radscheduler and a screenshot of the problem.  Any help is appreciated.

Hai, i got a problem using RadDateTimePicker.
I'm using a css class to apply style on button globally
The CSS style is like this:


and it makes the button ("Today", "OK", "Cancel") inside Calendar in RadDateTimePicker (On Calendar, Click on month, and it shows the button) is looks like disabled, and the cursor is "not-allowed" when i hover on it.

How to override the style on the button?

I have attach the image, it looks like disabled and the cursor is "not-allowed" (the screenshot in windows doesn't shows cursor, but believe me it's changed) 

I have a webpage that has 2 user controls on it. In one user control i have a RadMenu. In the other user control, underneath the first user control, a flash movie object is placed, When I am developing and I run the application on my machine using either IE or Firefox as my default, the RadMenu displays over the flash movie. I then deploy the code to my development server. When I run the application (development server) using the Firefox browser on my machine the RadMenu displays over the flash movie.

When I run the application (development server) using IE browser on my machine the RadMenu displays behind the flash movie. This is the same IE (version 8) that my machine uses when running it locally on my machine.

I have tried everything but cannot see what is wrong. Attached is the code being generated using FireFox (embed) and IE(object). In both cases the wmode is set to opaque.Any thoughts on why it is displaying behind the flash movie when running IE using the development server only?

Hello,

I have a tree with node templates that are added programmatically in the code-behind. The tree is set up to display checkboxes (Checkboxes="true") and the template includes a label and checkbox.  I want to set up the tree so that when checking the node's checkbox will also set the template's checkbox to the opposite value and viceversa (checking the template's checkbox will set the node's checkbox).  I have tried different approaches but I just can't get this to work.  Can anybody point me in the right direction.  Here's the code for the .aspx page:

<style type="text/css">
    .RedBoldFont
    {
        color: red;
        font-weight:bold;
    }
    .RedBoldItalicFont
    {
        color: red;
        font-weight:bold;
        font-style:italic;
    }
</style>
