Questions on UI for ASP.NET AJAX Forum

I have a RadToolBar on my page and I am wondering if I can use it as a history bar for where the user has been within my application. I want it to show the 10 most recently visited pages within my application. I want the oldest history to be on the left and the most recent history to be on the right. Some of the page names can get quite long, so I want it to truncate on the left. In other words, if the toolbar buttons are about to wrap (which I know they don't), then I want the left-most buttons to be truncated or removed entirely.

Problem is, I don't know what screen resolution the user will use on my site, and many of the button names are long. So, the buttons are added off the page to the right, so you can't see the button with the most recent page visited unless you scroll the page all the way to the right.

Has anyone been able to do this? Or have a reached the limits of what this control can do?

Grid columns doesn't sort

Dear All,

I have a gridview inside dynamic loaded user-control. This user-control is placed inside a radpane.

However, the grid is populated with a button clicked event then the datatable is stored in a session variable, this variable is casted back in the Need_Datasource event of the grid.

When I click any column header the data is not sorted (Asc or Desc).

What could be the reason of that ...

Best regards
Waleed

TabStrip behavior between IE7 and IE8

I have a TabStrip with a RadGrid.
I have a series of tabs that is enabled or disabled depending if the user selects, adds, deletes or modifies the grid.
(ex: the "Removed" tab is enabled when the user removes a row from the grid)

Here's how I'm enabling/disabling the tabs:

    
                        for ( var i = 0; i < tabstrip.Tabs.length; i++ ) 
        
                        { 
        
                            //  Get the current tab text. 
        
                            var tabText = tabstrip.Tabs[i].Text; 
        
                            //  Search for the old count number between the parens, 
        
                            //  then truncate it completely. 
        
                            tabText = tabText.substring( 0, tabText.indexOf( "(" ) ); 
        
                            //  Add the new count number, and set the tab text. 
        
                            tabText += "(" + tabCounts[i] + ")"; 
        
                            tabstrip.Tabs[i].SetText( tabText ); 
        
                            //  Enable/Disable based upon the bit mask. 
        
                            //  tab is always enabled. 
        
                            var enable = (i == 0) || (tabCounts[i] > 0); 
        
                            if ( enable ) 
        
                            { 
        
                                tabstrip.Tabs[i].Enable(); 
        
                            } 
        
                            else 
        
                            { 
        
                                var theTab = tabstrip.Tabs[i]; 
        
                                theTab.Disable(); 
        
                                theTab.DomElement.setAttribute( "disabled", false ); 
        
                            } 
        
                        }

Functionality wise, it works fine in both IE7 and IE8. However, in IE8, the text inside the disable tabs is a bold grey-ed out font which is hard to read. In IE7, the font is black. Any reason why it's like this?
