Title appears two times

Hi,
When I use the property "CaptionFormatString" to set a caption title to an autogenerated edit form, when I edit a record, the caption of the popup form is set accordingly but the title is also repeated an another time just below the caption of the form.

How can I prevent that oddly behavior ?

Thanks.

Collecting the Data for a Custom Sort

I need to implement a Custom Sort on a grid.

To do this, I need to pass the sort criteria to my Data Access Layer. I thought that the args for the SortCommand would provide me with what I need, but they only detail the column currently being sorted. I expected to discover in this object all of the sorted columns and their current sort order (to be clear, my grid allows multi-column sorting).

I then thought that I might be able to use the Grid.MasterTableView.SortExpressions collection, but that shows the old sort expressions.

Am I right in thinking that I have to manually create the current sort expressions collection from the old one and the args of the SortCommand event handler if I want the full sort expression for the grid?

'this._pickers.startDate' is null or not an object

VS 2010 (.NET 40) RadControls AJAX 2010 Q1

I'm using the most simple of setups... SQLDataSource and a table with only the columns suggested in the Scheduler's Data Source Configuration Wizard. If i double click on any appointment that isn't an All Day event, i'll get this script error message.

Error: 'this._pickers.startDate' is null or not an object

which, when viewed in the debugger, refers to this line of code (line 4779) of the Telerik.Web.UI.WebResource:

    
            var k=[$get(this._pickers.startDate.get_element().id+"_wrapper"),$get(this._pickers.startTime.get_element().id+"_wrapper"),$get(this._pickers.startTime.get_element().id+"_timeView_wrapper"),$get(this._pickers.endDate.get_element().id+"_wrapper"),$get(this._pickers.endTime.get_element().id+"_wrapper"),$get(this._pickers.endTime.get_element().id+"_timeView_wrapper"),$get(this._templateId+"_SharedCalendar")];

I have no other customizations to the RadScheduler:

    
            <telerik:RadScheduler ID="RadScheduler1" runat="server" DataEndField="EndDate"   
        
            DataKeyField="CalId" DataSourceID="SqlDataSource1" DataStartField="StartDate"   
        
            DataSubjectField="Subject" DataDescriptionField="Description"   
        
            DataRecurrenceField="RecurDesc" DataRecurrenceParentKeyField="RecurrenceID" >   
        
            </telerik:RadScheduler>

And i have one of these that comes before the RadScheduler declaration:

    
            <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">   
        
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server">   
        
            </telerik:RadScriptManager>

Any ideas?

'Security error' on RadAjax postback

I am receiving the following javascript error when doing a RadAjax postback:

Error:
uncaught exception: [Exception... "Security error"  code: "1000"
nsresult: "0x805303e8 (NS_ERROR_DOM_SECURITY_ERR)"  location: "http://localhost:2927/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_ctl00_am_sm_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-AU%3a8f393b2b-3315-402f-b504-cd6d2db001f6%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2010.1.519.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-AU%3afcd44c12-f50d-4937-b05d-1aa46b5c5b3e%3a16e4e7cd%3aed16cbdc%3af7645509

The ajax postback still works fine - but I am worried about this error.

Using Telerik 2010.1.519.35.

Do you know what it means?

AnimationType.Pulse

Is it just me or does the Pulse Animation Type not work.
It appears to first change the image and then pulse/fade.
Should it not do it between the images?
Or are my setting wrong.

I tried it by going to the demo site 'http://demos.telerik.com/aspnet-ajax/rotator/examples/default/defaultcs.aspx' and changing to slideshow and pulse.

It just looks wrong. I tried changing the scrollduration and frameduration to see if i can see it working better. But no avail.

Can someone shed some light on this?

Master and Detail Grids, but using OnNeedDataSource

Hello,

I'm trying to create a solution similiar to the Master/Detail demo.

I have 2 grids on a single page, MasterGrid and DetailsGrid.
I have AllowRowSelect="true" in MasterGrid and that works fine.
My problem is that I need to get the selected DataKeyValue (of MasterGrid) from within the DetailsGrid_NeedDataSource as a parameter value.

I can get the DataKeyValue from within a grids own GridCommand event, something like:

protected void MasterGrid_DeleteCommand(object source, GridCommandEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.Item;

int id = Convert.ToInt32(dataItem.GetDataKeyValue("ID"));

}

But again, I can't get the value in an unrelated method (NeedDataSource of a different grid).
Any assistance is appreciated.

Thank you,
Ronnie
