Is there a way to use a sprite for the button images and get the hover affect using another part of the sprite? I am currently setting the ImageUrl and HoveredImageUrl properties but with 10 buttons that causes 20 images to download. I would prefer to get that down to 1 image if possible.

Thanks.

MarkFirstMatch property with same text values

WE found a wierd behaviour, with RadComboBox , tried many different thing, and are lost, need some guidence.

    
            <telerik:RadComboBox ID="ddlDriverLastName" Runat="server" Skin="Office2007" DropDownWidth="470" Width="133"   
        
                                                             MarkFirstMatch="true" AllowCustomText="true" SelectOnTab="true" AutoPostBack="false"   
        
                                                             ShowWhileLoading="true" ToolTip="Select Driver" Sort="None" 
        
                                                             HighlightTemplatedItems="true" EnableItemCaching="false" Filter="Contains" 
        
                                                             OnClientSelectedIndexChanged="ChangeInputColor">

we have multicolumn dropdown with Last Names, when i bind the dropdown i set DriverID as value, and Last Name as text.

In case when we bind list that contains identical last names, we get this wierd behaviour, when first item in the list with the same last name is selected and page is reposted, the SelectedValue that is being passed by the control is that of the previously selected item with the same Last Name.
In other words, we can never get the first Last name item in the list, to be ever recognized as the one being selected.
Does anyone esle have this issue?

Disable listbox (with transferlist) without hiding transferbuttons?

Would it be possible to disable the listboxes without hiding the buttons that make it possible to swap items between the lists? (in other words, some sort of "ReadOnly"-mode, without changing the look of the controls)

Sys.WebForms.PageRequestManagerServerErrorException: Cannot find column

Hi guys:

I have created a RadGrid to connect to an OLAP datasource. That grid has three columns bounded to the following column names returned from that datasource:

[Periodo].[Periodo].[Mes].[MEMBER_CAPTION]
[Tipo Afiliado].[TipoAfiliado].[Tipo Afiliado].[MEMBER_CAPTION]
[Measures].[Total trabajadores afiliados]

When i want to click over one of the columns in the grid, i receive the following error:

Sys.WebForms.PageRequestManagerServerErrorException: Cannot find column Periodo].[Periodo].[Mes].[MEMBER_CAPTION.

Note that in the error description the column name given lacks the "[" character at the begining and the "]" character at the end.

If i configure the RadGrid to query a SQL Server database, the ordering works fine. I only have troubles with OLAP datasources.

                        ((RadGrid)source).DataSource = BillingItemsChildData(id);  
        
                    }

I've set the OnNeedDataSource attribute in the nested grid but it's getting called at the right times! The only way I can get this to work is to use a SqlDatasource in the .aspx file and that's just not an option for me. Also You see i'm sending the id (datakey) to the

BillingItemsChildData method but i'm not able to get the datakey from the parent inside this event. I've been testing by manually setting it.

I've been stuck on this for a while now. People on here have suggested that I use the detailsgridbind event but it's not a details grid, it's a nested radgrid.

I've tried setting the NeedDataSource event programmaticaly in just about every event in the page lifecycle and nothing works, only the .aspx SqlDataSource.

Thanks in advance.

Many thanks in advance.

Naming masterpage breaks controls

I have tried a few ways to name the masterpage (PreInit, Init) but it either does not change the masterpage id or the controls don't work properly. I am using the telerik RadINputManager to validate information on a form. If I change the masterpage ID it does not disable the user from submitting the form when there are errors. How can I get around this?

CaptionFormatString="Edit Item : {0}"

Hi everyone,
I am hoping for some help on something I am sure isn't a major.

I am taking advantage of the CaptionFormatString on a edit/insert form I am using. It works as it should when editing and when adding a form no text is displayed. When I insert a record (I keep the form open) the Caption is then displayed as Edit Item : {0}

Can I change this to be blank or a more friendly type of message?

Thank you

Shane
