Questions on UI for ASP.NET AJAX Forum

I am experiencing the strangest thing. It's odd enough that I must have done something idiotic.

I have a page with a RadScheduler. The page has a MasterPage and applies a very simple ASP.NET theme (just a stylesheet and some images -- no control skins or js.) Runs with v. 2009.1.402.35. With the theme, the page freezes when a user running IE (any version 6-8) clicks on Options in creating an appointment. Runs fine under Firefox or Safari for Windows, or if I remove the Theme declaration in the Page tag.

Like I said, it's a strange issue. Has anyone else experienced this?

ShowMoreResultsBox="true" produces exception

Using Telerik.Web.UI.dll 2009.1.402.35 I get an exception when the RadComboBox property ShowMoreResultsBox is set to true. If I remove the property I don't get the exception.The exception is not thrown (yellow page), however, I'm using the ELMAH "framework" to catch and log exception (see below).

The test page I've re-created the exception on has no code-behind and looks like this:

[Solved] RadCompression Problem

I've downloaded the latest version of the Telerik controls 2009.01.311.20 and I was trying to use the compression module but I get this error:

    
            Configuration Error  
        
            Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.  
        
            Parser Error Message: Unrecognized attribute 'EnablePostbackCompression'. Note that attribute names are case-sensitive. 
        
            Source Error:  
        
            Line 25:   </configSections> 
        
            Line 26:   <telerik.web.ui> 
        
            Line 27:     <radCompression EnablePostbackCompression="true" /> 
        
            Line 28:   </telerik.web.ui> 
        
            Line 29:   <connectionStrings>

I entered it exactly like it says in the online documentation, I pretty copied and pasted it in, and I receive that error. Did you rename that attribute or something?

Thanks,

Kevin

Adding nodes client side

Hi

I am trying to add nodes to rad tree view from java script method.

To get tree view object reference, I tried in three ways as below

case1: var

treeViewInstance = <%=RadTreeView1.ClientID %>;

case2: var

treeViewInstance = window["<%= RadTreeView1.ClientID %>"];

case3: var treeViewInstance =$find("<%= RadTreeView1.ClientID %>");

In case1, case2 object is loading into treeViewInstance, But it does not having the methodes like get_nodes, trackChanges, commitChanges.

Where as in case3 treeViewInstance becoming null.

Can any one suggest me to solve this problem!!!

Thanks in advance,

RadAjax and Firefox versus IE7

I have two panels. One contains a form, the other contains a grid. When I select a row from the grid, it posts back and updates the values in th form. It also contains a combobox, when clicked it also updates the form panel on the left.

I have wrapped both panels with RadAjaxPanel.

In IE7, it handles the ajax fine and updates the form values without a visible postback, refresh of the page, etc.

In Firefox, with the RadAjaxPanel, it allows one click, and then the grid is locked up and the so is the comboxbox and no amount of clicking will update either. As well, the length of the grid is messed up and too long.

In IE7, it works as expected.

If I remove the RadAjaxPanel, IE7 posts back and refreshes visibly as expected. But Firefox now works as though it has an Ajaxpanel loaded in automatically! It works great without the RadAjaxPanel at all.

Has anyone else experienced this? Does Firefox have Ajax built into the panels? This is very strange. I have deleted and added back several times and tested and retested just to confirm what I think I'm seeing.

Any ideas?

I am using Firefox version 3.0.8.

thanks.

Using NextPrevNumericAndAdvanced Pager in Master table and Detail table

I use RadGrid control version 4.6.

I want to use NextPrevNumericAndAdvanced Pager for my grid to be able to manipulate the size of the master and detail tables. I can resize the master table. Unfortunately, when I resize the master table, the dimensions of the detail table are also changed. It is not the behavior I need. I need both of the table view to work completely separately.

Another problem I have is when I try to change the size of detail table; I’m getting the following exception:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Best way to display different content in same RAD Window depending on clicked button in toolstrip?

Hi,

I have a Rad Window and a menu on an ASP.NET MVC app.

I was wondering, what is the best way to load completely different content when a button on the toolbar is clicked?

For example, on page load, I have some welcoming text in the Window, but if I click "skills" in the toolstrip, I would like to eradicate the welcoming text and show a rad data grid, slider, etc? Maybe I need seperate RAD windows but wouldn't this harm performance?

Thanks
