Hello!

RadCarousel is a great component and it makes the application that I'm working on look so profesional even if I don't have a designer backgound or so.
There are a couple of addition things that I would need from this component, they may be already there but I don't know how to take advantage of them.
First of all - I need to always have one selected CarouselItem out there, no matter if I've clicked one or not.
If I press an additional "Load" button I should always have the possibility to retrieve the top most carousel item there
( right now carousel.SelectedItem can return null if there was no click on a specific item )
Second - Reffering the beginning or the end of carousel items sequence - I should have the possibility to stop the flow of the items (if I continuously press the carousel's ScrollViewer buttons) I mean that the last item should be in the middle of the screen and not somewhere far in the left/right of the screen (check out the attachments) - and this last one should be the SelectedItem also

separate context menu for grid headers

Hi,

I need separate context menu for the grid rows and the grid headers.

I defined the rows context menu in the xaml like this:

<telerikGrid:RadGridView x:Name="ordersGrid" AutoGenerateColumns="False" DataLoadMode="Synchronous" >

<Navigation:RadContextMenu.ContextMenu>

<Navigation:RadContextMenu Opened="RadContextMenu_Opened" ItemClick="RadContextMenu_ItemClick">

<Navigation:RadContextMenu.Items>

<Navigation:RadMenuItem Header="Update Order" />

<Navigation:RadMenuItem Header="Cancel Order" />

<Navigation:RadMenuItem Header="View Details" />

</Navigation:RadContextMenu.Items>

</Navigation:RadContextMenu>

</Navigation:RadContextMenu.ContextMenu>

and i defined in the code the context menu for the headers.

The problem is that the main context menu overrides the header context menu. I even try to remove it in the loaded event but it didn't help:

void ordersGrid_Loaded(object sender, RoutedEventArgs e)

{

GridViewHeaderRow headerRow = ordersGrid.ChildrenOfType<GridViewHeaderRow>().FirstOrDefault();

IEnumerable<GridViewHeaderCell> cells = headerRow.Cells.OfType<GridViewHeaderCell>();

/**remove the default menu from the header in order to ser a separate menu for header**/

foreach (GridViewHeaderCell cell in cells)

{

var x = cell.ContextMenu;

RadContextMenu.SetContextMenu(cell, null);

}

GridViewHeaderMenu gvhm = new GridViewHeaderMenu(ordersGrid);

gvhm.InitializeMenus();

}

How can i achieve it?

Thanks,

Ofer

How can I catch invalid entries as ValidationError?

Hello,

I have the following problem: I have a form with a RadDatePicker in it. Everything works fine, but when I enter an invalid date into the entry field of the picker, the date is just resetted or the entry field of the picker is empty. I would prefer to see the defined ErrorTemplate instead.
I tried to catch this by adding ValidatesOnError to the Binding in the XAML file but it doesnt work.

So: How can I catch it if the user enters an invalid value to the entry field?

Best Regards,
Jerma

ReadOnly Cell and GridViewCell.PreviewEditStartEvent

I'm using RadGridView and need to prevent editing for some cells not at the column level, but based on the row and column.

I've tried using ReadOnly Cell and GridViewCell.PreviewEditStartEvent as described here:

http://www.telerik.com/community/forums/wpf/gridview/set-read-only-property-for-cell.aspx

It appears in the version I am using the PreviewEditStartEvent does not exist. Am I missing something? Was this removed?

I have version 2009.3.1208.35.

Thanks,

Mike

New to WPF/DataBinding

How do I bind a GridView to a dataset, is it even possible? I looked iin the guide book and they all seem to binding via the code and in the ASP.NET version you can just link it to the SQL datasouce you created. (Again dont know much of this WPF world)

Im use to the ASP.NET RadGrid and binding options but Im trying to see if I can get one of my larger applications to run in WPF.

Im using Q3 WPF and VB. I added a DataSet and have the query I want in it. (I just left it the default "DataSet1.xsd" with all the default values for testing.)

Unable to drag Telerik controls from Toolbox onto designer

I'm unable to drag Telerik controls from the VS Toolbox onto my WPF design. When I try, I get the classic circle with a slash through it, generally used to indicate an operation is prohibited. I can drag regular MS controls from the toolbox onto the designer but not Telerik controls. Any suggestions for resolving this?

Thanks,
Scott
