Datepicker setDate

Hi everyone,

If found something strange about the way setDate behaves when passing a date object in parameter.

I use the fonction like this:
var date = new Date();
alert(date); // Tue Aug 25 2009 16:58:26 CTU+0800
$('#datepicker).datepicker('setDate', date);
alert(date); // Tue Aug 25 2009 16:58:57 CTU+0800

Why does the setDate function modifies the date object? Is this normal?
How to modifiy format of the date ,eg 'yy-MM-dd'?
I didn't find anything about this subject on the website.

Thanks a lot

Request: More built-in themes

I would like to make a request for more built-in themes. Ideally, I would like to see a good 20 or 30 of them to choose from instead of 4. I know it just came out, so I'm glad it at least has four, but I'd rather not have to sit in Blend and mess around with customizing the template unless I really have to. It looks like with templates, you can basically do anything you want with the chart...the xaml just really gets complicated (I'm no wpf expert yet though, so maybe it is just a learning curve I need to get over).

On a side note, my post about hiding the legend just disappeared completely from the forum. Also, subscribing to threads seems to not work. Maybe the new website changes caused some glitches.

[Solved] Rad Drag and Drop example

I was wondering if there if someone has an example of using the rad drag and drop to rearrange items in a WPF list box. I found the example to drag and drop from one control to another, but I am looking for direction on how to drag and drop to rearrange items in a single control.

Thanks

Scheduler example goes haywire in VS2008 designer

I build the Example solution and then opened:
When I try to view Scheduler -> WPF -> FirstLook -> Example.xaml

The Scheduler displayed, but started stretching (scaling) horizontally and never stopped stretching. The size Eventually I closed Example.xaml and reopened. The initial screen showed up fine again but started stretching horizontally, indefinitely.

The other examples show fine, only the scheduler shows this behaviour. Also if I hold down the left mouse button inside the design window, the stretching speeds up!

Running the Example under Debug / Run works fine, its only under the designer.

I'm using VS 2008 with SP1 installed.

[Solved] How to enable tabs inside a cell editor

Hi,

to edit custom data I provide my own editor (some controls for the data).
Assume there are some checkboxes. I uncheck (by mouse) the first and then I decide to use keyboard input.
So I press tab to go to the next checkbox (or whatever there is in my "user control").
But instead of selecting the next element in my editor it leaves the cell.

Did I oversee some property I have to set - or does this mean "RadGridView" has limited keyboard support?

If you want to see what I mean you can check (after screening) my code library post here:
http://www.telerik.com/community/code-library/wpf/gridview.aspx (custom editor...)

multiple data series

I have a table that looks like this:

Date_time, sensor_port_number, value

There is more than 1 “sensor_port_number”

How would you display this data in your chart so that all “sensor_port_number” values are displayed in the same chart

So each “sensor_port_number” is series data

Can your product do this? and if yes can you tell me how please.

thanks,

martin

filtering problem

i get following exception while trying to filter at runtime using UI:
"'System.Object' is not a valid metadata type for type filtering operations. Type filtering is only valid on entity types and complex types."

When i add filter in code :
FilterDescriptor fd=new FilterDescriptor("nazwa",FilterOperator.Contains,"GT");
view.FilterDescriptors.Add(fd);
everything works.

binding code:             QueryableCollectionView view = new QueryableCollectionView(presenter.Model.EntityList);
            view.PageSize = 1000;
            SortDescriptor sd=new SortDescriptor();
            sd.Member = "nazwa";
            sd.SortDirection = System.ComponentModel.ListSortDirection.Ascending;
            view.SortDescriptors.Add(sd);
            radGridView1.ItemsSource = view;

presenter.Model.EntityList contains objects that derive from EntityObject(so i think they are of "entity type" ).
What should i do to avoid this problem?

IsBusy property for gridView - why ReadOnly ?

Hi,

I am just wondering if there any reason why IsBusy property of GirdView is readonly? It would be great to be able change this property to True while loading data from database, then assign the data to gridView.ItemsSource and then set IsBusy to false.
My problem is that database which is used by application might be somewhere in the Internet not in local network. So when I have to fetch a lots of data from DB, it may take about 10 seconds. During this time it would be great to set IsBusy to true and when data are fetched, assign the collection to the ItemSource and resotre the grid. Now it looks like this: UI hangs when fetching the data for 10 seconds and then when collection is assigned the busy icon is animated for about 1 sec.

Could you provide some example how to solve such an issue?
Maybe I can change RadGridView soruce code and change setter of IsBusy to public?

Cheers!
