Filter menu disappear with radajaxmanager

I have a radgrid and a radajaxmanager (2008 Q3) in a page.

It is a simple page, basically, it has the radgrid's NeedDataSource and an itemdatabound to generate the row numbering.

When the page is first load, the filtering function is fine.

Then, if I perform a second filtering, the filter context memu does not appear, with script error:

    
            'null' is not or not an object

If I removed the radajaxmanager, second filtering is ok.

The code:

    
            Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs)  
        
                    Dim myTable As New DataTable  
        
                    myTable = dbSearchPart_Cost 
        
                    If myTable Is Nothing Then  
        
                        msgMessage.Text = "System error.  Cannot connect to database! " 
        
                        GoTo error_exit  
        
                    End If  
        
                    RadGrid1.DataSource = myTable 
        
                    GoTo exit_sub  
        
            error_exit:  
        
                    msgMessage.CssClass = "ErrorText" 
        
            exit_sub:  
        
                    myTable = Nothing 
        
                End Sub  
        
                Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound  
        
                    If (TypeOf e.Item Is GridDataItem) Then  
        
                        Dim lbl As Label = CType(e.Item.FindControl("numberLabel"), Label)  
        
                        lbl.Text = e.Item.ItemIndex + 1  
        
                    End If  
        
                End Sub

And the ajaxmanager:

                DefaultLoadingPanelID="RadAjaxLoadingPanel1">

                        </UpdatedControls> 
        
                    </telerik:AjaxSetting>

Question on Scheduler/ToolTip Demo

Hello,
I have a general question on the demo found at http://demos.telerik.com/aspnet-ajax/scheduler/examples/radtooltip/defaultcs.aspx
I was able to duplicate this in my project, and it works perfectly. I do not like simply cutting and pasting unless I fully understand the detail.   I am currious why the Scheduler appointment created and databoud events are assigned the way they are in the example. Instead of declaring them in tag attributes in the ascx file, they are assigned values in the code behind in the page load. In addition, using the += and without checking for postback appears to me as though we are adding multiple duplicate event handlers. I do not pertend to be an expert on this, in fact, it is why I ask the question as to gain a better understanding. The following shows the page load from this exampe.

private void Page_Load(object sender, EventArgs e)
        {
            RadScheduler1.AppointmentCreated += RadScheduler1_AppointmentCreated;
            RadScheduler1.DataBound += RadScheduler1_DataBound;
        }

Some more necessary features

Hello,

From what I see in your demo, your captcha is missing:
- using random colors for letters (very nice to see) and not only one color,
- optionally working as a page validator (could be turn on by a property) with validation group.
- auto reset after ajax request

Hope it will be in Q2 :)

Thanks
CS

FlashManager "Could not find the command" error

I added entries within the <tools> element in this file:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\wpresources\RadEditorSharePoint\4.5.6.0__1f131a624888eeed\RadControls\Editor\ToolsFile.xml

as follows:

    
                <!-- Added for media files --> 
        
                <tool name="FlashManager" /> 
        
                <tool name="MediaManager" />

I saved the file, reset IIS on the server and the buttons appear on the toolbar when I edit a RADControl web part. But when I click on the buttons I get an error dialog:

Could not find the command FlashManager. Please update your command list.

Anyone got any idea why? The help file says I should be able to use the FlashManager control right?

My server is 64 bit Windows Server 2003

Auto-generated javascripts

In a couple of Grids of mine i have a column with a ComboBox in it. The ComboBox is using LoadOnDemand and javascript to handle this is auto-generated by the ComboBox for each row in the grid.

Is there any good way or best practices to reduce the amount of javascript being generated?

Thanks in advance!

Inline Edit Mode on single click

Is it possible to take the grid row into Inline Edit Mode on a single click. I want the previous row's update command to be fired and the edited row's Edit Command events to be fired. If the update command fails due to validation, I want to be able to retain the user in the previous row. There is an example using double-click and click which I have already looked into but I want to something similar with a single row click.

Thanks

Image Manager - all images have wrong height

Hello,
From the rad editor - select image manager.
All images are viewable, I can upload, delete, and re-name.

However if I select an image and go to properties the height is always 15 and the width is always 0.
If I just select an image (skipping viewing properties) and insert in into the rad editor content area there will be a style that set width=0 and height =15.

What's the bug here?
thanks!!
