HighlightCssClass of AJAX ValidatorCalloutExtender, for radtimepicker

Hello, i have the following css class that has worked for almost every ASP.NET control i have worked with. it is used with the HighlighCssClass of validatorcalloutextender (see below). All it does is outline the field in red that are not valid, it does not work with the radtimepicker, and thoughts on how to get this to work?? I tried putting the same style on just the endTimeInput part, that does what i want, but when i point the requiredfieldvalidator to the DateInput of endTimeInput it errors and cant find the control, but this is the part of the control i want outlined in red. thanks

.ValidatorCallout
{
    border:solid;
    border-color:#FF0000;
    border-width:2px;
}

<telerik:RadTimePicker ID="rad_TimeEnds" runat="server" Width="85px">
            <TimeView ID="TimeView2" runat="server" StartTime="9:0:0" EndTime="22:31:00" Interval="0:30:0" Columns="5" TimeFormat="HH:mm" Culture="en-US"></TimeView>

[Solved] Line Chart with Pivot Data?

Hello,
I'm trying to create a line chart using pivot data returned from SQL Server. For example. Column 1 is a Product List and columns 2 - 13 represent each month of the year with a sales figure. Can anyone point me to a demo or sample that demonstrates how to get a line chart from this data. I haven't gotten anywhere on my own and looking over the live demos application hasn't gotten me anywhere.

I'd like the y axis to be a 1 - 100,000 range and the x axis to represent the months of the year. Then a line representing each of the products.

I appreciate the help.

Thank you,
Vinny

Problem with client event handlers on menu in UpdatePanel

I have a RadMenu that exists in a MasterPage. The master page adds a client event handler to the OnClientItemClicking event. Here's the code:

    
                <script type="text/javascript">  
        
                    function PageLoad()  
        
                    {  
        
                        var menu = $find("<%= MasterMenuInner.ClientID %>");  
        
                        menu.add_itemClicking(MenuItemClicking);  
        
                    }  
        
                </script>

The PageLoad() function is called by the body "onload" event.

The content page also needs to handle the OnClientItemClicking event. Here's the code for that:

    
                    function MenuItemClickingConfirmDelete(sender, args)  
        
                    {    
        
                         var itemValue = args.get_item().get_value();  
        
                         if (itemValue == 'Delete')  
        
                         {  
        
                            if (confirm('Delete this invoice?'))  
        
                            {  
        
                                args.set_cancel(true);  
        
                            }  
        
                         }  
        
                    }  
        
                    function InvoiceListPageLoad()  
        
                    {  
        
                        var menu = $find("<%= Master.MasterMenu.ClientID %>");  
        
                        if (menu)  
        
                        {  
        
                            menu.add_itemClicking(MenuItemClickingConfirmDelete);  
        
                        }  
        
                        else  
        
                        {  
        
                            alert("<%= Master.MasterMenu.ClientID %> not found!");  
        
                        }  
        
                    }

The "InvoiceListPageLoad()" function is also called by the body "onload" event.

So, everything works fine on the initial page load. Both event handlers fire as expected. Great.

The problem starts when the menu (on the master page) is updated. During an AJAX postback, I enable/disable some buttons. The menu is inside an UpdatePanel. The menu updates fine, but all client event handlers are "lost". I guess they are not part of the control state or view state. Obviously the body "onload" event doesn't fire after an AJAX postback.

I tried using the following code to re-register the event handlers after an AJAX postback:

ScriptManager.RegisterStartupScript(this, this.GetType(), "startup", "InvoiceListPageLoad();", true);

Unfortunately, I always get the alert box that says "ctl00_MasterMenuInner not found!"

How do I register a client event handler after an AJAX postback?

Persisting Checkboxes in new grid

Hi there,
I had a huge long client script for RadGrid that persists checkboxes and rowselection into HashValues on client RowSelect and RowDeselect. I got the code from a Telerik forum for the old Grid and now that I've upgraded to Prometheus the Code is obosolete. Anybody have some code on how to client side persist Checkboxes and Row Selection for the new Ajax Grid? Or just a real simple way to do this? I basically want to implement a Client Select Column that allows CheckAll UncheckAll and doesn't lose Selection while paging or using AjaxRequests.

Thanks.

Set Focus to control under the tabstrip

Hi,

I have TabStrip with three tabs. When users click on the submit button, I have java script, it will validate all the controls of each tab with in the tabstrip. If anyone of the control does not enter the value my java scrip will popup the alert message.

What I am looking here is, after the pop-up this message it should set the focus to that particular control. I have all RadtextBoxes and Radcombo boxes with in the tabs. Please send me the javascript snippet which should set focus to control (RadTextBox or Radcombo) under the specific tab

Thanks,
Sravan

Radtooltip in Scheduler in DNN

I'm recreating your example on using the Radtolltip in the Scheduler, however in a DNN module. Has anyone succeeded with it? If you try it one to one there are 2 problems I encounter:

a) There is an error that the module couldn't load totally. However, the schedule shows.
b) Dim toolTip As AppointmentToolTip ...Will not be recognised as defined.

Should anyone have tried this and succeeded - I'd be thankful for info's on how you did it.

Unable to rebind the datagrid using AjaxManager

Hi,

I am using new RadControl ASP.NET for AJAX latest build.

I am testing the RadGrid and having problem.

Here is the scenario.
I do have MasterPage. The ScriptManager is inside masterpage.
I have a page that is using MasterPage.
The page contains a RadGrid and DataSource connect to SQL Server.

The RadGrid allows user to add, modify and delete. The Add / Modify button using RadWindow when its clicked.

when the user clicked "Modify" inside the grid (from one of the row), there will be a window pop up. Once the user update the button, the RadWindow will be closed and the AjaxManager.AjaxRequest('Rebind') is called. The AjaxRequest contains "RadGrid1.Rebind()" command.
Once the AjaxRequest is called, I got the following error:
-------------------------

Value cannot be null.
Parameter name: key

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.

Exception Details: System.ArgumentNullException: Value cannot be null.

Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433
----------------------------------

I have double checked the DataKeyValues in the Grid and its there. I dont know what is going on.

I tried so many things to work around it, but unable to do so. I tried using RadAjaxPanel, RadAjaxManager, PostBack when the window closed, etc, but all failed.

In summary,
- The page contains MasterPage that have ScriptManager
- The page contains RadGrid that will popup RadWindow.
- I have followed the sample from LiveDemo but failed as well.

Anyone can help me out ?

Thanks.
