Hi,

I have used a candlestick and a barchart in same page. When I changed the zooming parameters and scrolling the scrollbar, the candlestick's DateTimeCategoricalAxis display has some problem, please see the picture.

Hi,

I would like my application to save the grid state (sort, column order, filters, etc) and then when restarted I would like to re-apply these settings.

I started playing around with this idea only to find the SortDescription and CompositeFilterDescription are not Serializable.  Can we please make these serializable in a future release?  Even better can we add the methods:
RadGridView.SaveGridState(string filename)
RadGridView.LoadGridState(string filename)

Thanks

Hi,

I'm having trouble changing the dictionary to en-GB when the RadRichTextBox control is hosted in a RadWindow rather than a standard window.
It will be easier to see some coding examples of my problem.

Initial Loading Code:


Notice that I'm using a class called RadWindowHelper2 and a method windowHelper_TraskBarDisplayed(). I obtained this code somewhere in these forums so that a taskbar item is displayed.
At the end of the initial code I then call LoadDictionary() to change the dictionary to en-GB.


RadWindowsHelper2 class

windowHelper_TaskBarDisplayed()


LoadDictionary()

I can get the window to load and radrichtextbox to show providing I do one of the following:

1. Comment out LoadDictionary() method call   (loads RadWindow with a taskbar icon but doesn't change dictionary)
2. Comment out the code that creates an instance of RadWindowHelper2   (loads RadWindow without a taskbar icon but does change dictionary to en-GB)

For some reason I cannot get both of the above methods to load together.

Here's the exception and stack trace when I try to show a taskbar icon and change the dictionary to en-GB:

Exception:
NullReferenceException was unhandled

Object reference not set to an instance of an object.

Any advice would be greatly appreciated.

Hi There,

first i want to explain to you what i want, than how i solved it and finally what my problem is.

I was looking for a SelectionChangedEvent on a GridViewComboBoxColumn because based on the selection i have to calculate another property of my "RowItem".
e.g. A user change the value in my first column ( a GridViewComboBoxColumn ), so the value in column no 3 has to be calculated.

Because i didn't find an event, which i can use.

I created my own column, it work mostly:


My problem is now that i am unable to get the row item in my gridview to set the property for the third column.
Can somebody helps me by this issue? Or is it the wrong why to solve this problem?

Many thanks in advance for your cooperation

My tileView has tileItems that have an image thumbnail along with other things. The process that loads these images is a time-taking process. I want to load the image thumbnails only if the Tile item is within the viewable area. So if my current viewarea shows 50 tile items out of 100 tile items, I want to load the images for only those 50 that are visible. When the user scrolls the tileview and other tileitems come into view, then I want to load the images for these tileitems too.

Is there any event that I can use, to call my load image code....maybe something like tileitem post rendering or something.
I will be grateful for any code samples.
Thanks,

Hi,
I have RadCarousel which contains RadCarouselPanel for its items Panel. I use a horizontal path and have 3 items per page. The HorizontalScrollBarVisibility has been made to hidden and I use the CarouselButtons.
The way it is laid out is I have a grid panel with 3 columns and widht of the grid being 1022. The centre contains the radcarousel, and on either side the carousel scroll buttons with width 38 px each. The centre column occupies the rest of the space in the grid. So I want to specify the width between the panels in the radcarousel.
And also I wanted to know if there is anyway to connect the the items in the rad carousel panel Here is the explanation for the connectors
[prev]=[Main]=[next]
[prev] is the panel that is on the left side of the focussed item on carousel
[Main] is the panel that is the focussed item on carousel
[next] is the panel that is on the right side of the focussed item on carousel
= are the connectors between panels

Is there a way to achieve this requirement. Any help is appreciated. I use the v2012_3_1017_40_noxaml version from telerik.

Thank you
YK

Hi,

I'm using a RadGridView to display several thousand objects stored in an ObservableCollection.
The GridView is bound to the PagedItems on a DataPager, which is bound to the ObservableCollection.
I use filters on the columns in the GridView to filter down the data, so that instead of 250 pages, I get 5 pages.

How can I access these items in these pages? That is, all the items that matches the filter, and not only the items on the current page.
(the items on the current page I can access by gridView.Items, but it does not show the whole collection)

Hi,

I am trying to create a cutom look for the RadGridView to suit our application theme. The templates are based on telerik default templates where you have used some converters:
FilterOperatorConverter,FilterCompositionLogicalOperatorConverter,DistinctValueConverter etc..
No matter how I declare them in a resource dictionary I get errors:

The first decleration prompts the error:
Ambiguous type reference. A type named 'FilterOperatorConverter' occurs in at least two namespaces, 'Telerik.Windows.Controls.GridView' and 'Telerik.Windows.Data'. Consider adjusting the assembly XmlnsDefinition attributes. C:\dev\trunk\WPFClient\Views\RequestSubmitView.xaml 1 1 WPFClient

The second decleration prompts the error:
The name "FilterOperatorConverter" does not exist in the namespace "clr-namespace:Telerik.Windows.Controls.GridView;assembly=Telerik.Windows.Controls.GridView,Version=2012.3.1017.40,Culture=neutral,PublicKeyToken=5803cfa389c90ce7". C:\dev\trunk\WPFClient\Views\RequestSubmitView.xaml 90 13 WPFClient

There are a few odd things about this bug.
1)At runtime everything works fine. The problem is limited to design time and the visual studio designer does not work because of this.
2)I've tried this out in an external test application and the second decleration  work fine. It only happens in our project. It is not originally a .net 4 application but was upgraded from 3.5.

Thanks,

Gary
