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

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

Hi, I'd like to disable drag and drop reordering of columns in a RadGridView. I set CanUserSortColumns to false, but this doesn't seem to make a difference. I setup the grid like so:


What do I need to do to disable this feature?

Hi Telerik,

I'm using HierarchicalDataTemplate in RadPanelItem for my datasource. I need to use drag-n-drop to reorder items and groups in RadPanelBar.

1. When user drags HeaderRow (group item) he should be able to change order of this group in list as result.

Original:                                  After drag-n-drop by group header to the begin of list:
Group1                                   Group2
    Item11                                     Item21
    Item12                                     Item22
    Item13                                Group1        
Group2 <--dragged to begin       Item11
    Item21                                     Item12
    Item22                                     Item13


2. User also should be able to reorder item(s) (one or multiply selected) inside one group or move it to another group using drag-n-drop.


I'm more interested in the definition and visualization of position within the list where item should be moved.
Can you help me with direction of search or maybe little example?

Thanks.

When the arrows are clicked little faster , the calendar keeps loading few months & repeating the same cycle, does not move to further months. Not getting what is the bug because when I click on the arrows patiently like taking a second's gap in each click, then the datepicker loads properly.

Using virtualizing panel as itemspanel does not resize the dropdown height and also another behavior i got was it does not filter the items as it focused the correct item but in the case when it has lots of items in my  case 5000 items it searches correctly but does not filter. Can someone suggest how to fix this issue. I have created a sample project with this. The project has two dropdowns with seperate behaviors 

1) Dropdown height is not resizing on filtering.
2) Large Collection finds the item but does not filter the items.

Sample Project can be found here
