ScrollChildren and EnableEmbeddedSkins

I am using a TabStrip control with the following definition:

    
                        <telerik:RadTabStrip ID="RadTabStrip1" SelectedIndex="0" runat="server" MultiPageID="RadMultiPage1" 
        
                            Width="100%" EnableEmbeddedSkins="False" Skin="" ScrollChildren="true">  
        
                        </telerik:RadTabStrip> 
        
                        <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0">  
        
                        </telerik:RadMultiPage>

I am creating the tabs in code with user controls:

    
                Private lngCampaignId As SqlDecimal  
        
                Public Property CampaignId() As SqlDecimal  
        
                    Get  
        
                        Return lngCampaignId  
        
                    End Get  
        
                    Set(ByVal value As SqlDecimal)  
        
                        lngCampaignId = value 
        
                    End Set  
        
                End Property

And using the following css:

    
            .normaltab  
        
            {  
        
                background: url('../Images/bookstore_activetab.jpg') no-repeat;  
        
                font-family: Verdana, Arial, Helvetica, sans-serif;  
        
                font-size: 11px;  
        
                text-align:left;  
        
                width: 175px;  
        
                height: 28px;  
        
                color: #5b3b23;  
        
                padding-top: 10px !important;  
        
            }  
        
            .selectedtab  
        
            {  
        
                background: url('../images/bookstore_inactivetab.jpg') no-repeat;  
        
            }  
        
            .hovertab  
        
            {  
        
                color: #ad9d91;  
        
            }  
        
            .pageview  
        
            {  
        
                background-color: #EBF5F6;  
        
            }

My problem is that when I have ScrollChildren on, my tabs disappear. I believe that it is because I am not using a standard skin. Can you tell me what other css styles I need to define in order to use ScrollChildren with my custom tab css.

Thanks.
Dan

Adding multiple items using DataNavigateUrlFormatString

Hi,

I have a grid and a date range parameter and need to send those date parameter values through the DataNavigateUrlFormat. How can I do this without hardcoding those values and using the date parameter values (dynamic values)

Example: In the column mentioned below I want to pass “From Date” and “To Date” values as part of the query string.

<telerik:GridHyperLinkColumn DataNavigateUrlFields="EmailCampaigns" UniqueName="EmailCampaigns"

DataNavigateUrlFormatString="EmailTrackingBreakup.aspx?MailType={0}&FrmDt=01/01/2009&ToDt=05/31/2009" DataTextField="EmailCampaigns"

HeaderText="Email Campaigns" SortExpression="EmailCampaigns">

</telerik:GridHyperLinkColumn>

Thanks,

Grid

[Solved] Error sending JSON object to AjaxManager via AjaxRequest

Hi,

I have bumped into a small issue regarding sending a JSON object to AjaxManager from client side javascript.

I'm trying to send this string representation of a JSON object:

    
            {'cmd':'Rebind','data':[{'newid':5},{'newname':'test'}]} 
        

Client side script calling ajaxRequest() thus:

    
            function refreshView(args) { 
        
                var ajxmgr_id = '<%= RadAjaxManager.GetCurrent(Page).ClientID %>'; 
        
                var oAjxMgr = $find(ajxmgr_id); 
        
                var jsonArgs = JSON.stringify(args); 
        
                oAjxMgr.ajaxRequest(jsonArgs); 
        
            }

where "args" is the JSON object.

Error message received when passing this JSON object:

Sys.WebForms.PageRequestManagerServerErrorException: Type System.String not supported for deserializing a matrix.

This is the full error message I receive (excuse the Norwegian :P )

As you can see the JSON object has a nested array in it ('data':[...]). Are there limitations to the complexity of the JSON strings I can pass to ajaxRequest()?

The problem is circumvented by simplifying the JSON object to a flat structure; i.e.:

    
            {'cmd':'Rebind','newid':5,'newname':'test'}

With same client side script above, there are no errors and everything works fine.

Is it possible to pass complex nested JSON objects as strings or can I only send flat structured {"key", "value", ...} type objects?

I'm using the lastes RadControls for ASP.NET Ajax (2009.2.701.35)

regards,
Ernst

RadGrid delete command code

I used from the training book the delete command. The problem that I am having is when I try to delete a record in the RadGrid, I get the following error:

Object referance not set to an instance of an object

The weird thing is I got it from the Telerik RadControls Ajax book and besides that I have no clue. See attached code:

    
            Imports System.Data.SqlClient  
        
            Imports Telerik.Web.UI  
        
            Partial Class EmployeeFamily  
        
                Inherits System.Web.UI.Page  
        
                Protected Sub RadGrid1_DeleteCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.DeleteCommand  
        
                    Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)  
        
                    Dim MemberFamilyID As String = item.OwnerTableView.DataKeyValues(item.ItemIndex)("MemberFamilyID").ToString()  
        
                    Try 
        
                        'Delete command execute  
        
                        SqlDataSource1.DeleteCommand = "DELETE FROM MemberFamilyInfo Where MemberFamilyID = '" + MemberFamilyID + "'" 
        
                    Catch ex As Exception  
        
                        RadGrid1.Controls.Add(New LiteralControl("Unable to delete MemberFamily. Reason: " + ex.Message))  
        
                        e.Canceled = True 
        
                    End Try 
        
                End Sub

Different image for each item on custom skin

Hey!

I've got a custom skin for a Panel Bar with each item's background image
as well as rollover image set in the skin file in CSS. However, what I need
is to set the images dynamically because each item is a product category
that has its own background image. I understand there's different ways
of doing this - and I'm also cautious of performance... Any advice and
examples much appreciated!!

no images in dropdown when setting a filter

Hi,

when setting the filter attribute of the comboboxcontrol to one of the available types, i got a problem with assigned images.
The images where not shown in the generated dropdownbox. Not setting the filter shows all assigned images as wished.

Is this a known or volitional issue, or is this a bug?
I would like to see the images there, why is it not possible?

Or am i just doing something wrong?

Thanks for a short reply.
