I have a RadTileView, with ItemsSource set to an ObservableCollection. RadTileViewItem.Position is configured to bind to a property on each item named Position. This seems to work fine for the initial load... however, when the Position property is updated, the RadTileView does not reorder the tiles.

I think it probably has something to do with items being added one at a time to the ObservableCollection, and then their Position values are being rebuilt en-mass.

Are there any specifics I should know about here? Basically I need a list of tiles, with items being added and removed on the fly, and also changing position.

[EDIT]

Okay. I have the reordering working. The issue seems to be that if the Binding on Position is not TwoWay, it is simple ignored, and the order in the collection controls the order of the tiles. This seems odd, as I don't desire TwoWay binding... I just want to be able to change it.

I'm still suffering from two issues. One, is the animations don't work. The tiles don't slide around. I have set a ReorderingDuration as well as ElasticEase as the ReorderingEasing. However, the tiles still just jump.

Second, there seems to still be something wrong with adding tiles. Sometimes, when I add items to the underlying collection, the tiles aren't actually created. Theres just blank spaces where the tiles should be.

[EDIT]

Okay. I've figured most of this out. Position must be two way, because TileView does not simply read from Position, but adjusts the positions of other tiles in order to reorder them. So if I change the position of an object in the collection, the TileView will go and change the positions of OTHER elements in the collection. And it looks like it only really likes to change the position of one thing at a time. So, fine. Instead of rebuilding all the positions in a loop; I'm only setting the position of the first item in the collection that's at the incorrect position. The loop then comes around again after 1 second, and does the same thing to the next item. And it only shifts it by one position at a time. So, if the position is > than it should be, I Position-- it. If it's less than it should be, I Position++ it. Eventually they are all the proper value.

This is kind of obnoxious. It'd be easier of I could just reset the positions of all items of the collection to the proper position and have the TileView move them around properly.

Second, my animations are still broken. But I figured out why. I'm overriding the Template of RadTileViewItem in order to remove the Header. For some reason, this destroys the animations. I still need help figuring out how to fix the animations.

[EDIT]

Success! I had to put TWO unnamed, unused Grid elements as the root of the RadTileViewItem.Template. That is totally undocumented. Somebody should document this somehow. =)

Hi Team!

I'm having the following exception throwed sometimes (I can't reproduce it consistently).

Is this a bug? 

 

Thanks a lot!

Best regards,

I have a RadGridView which used for displaying data. Since the i have many columns to display, so i fixed part of the columns and there will be a scroll bar for user to see all the columns. the issue is it cannot show all the columns when i choose 1027*768 screen resolution even max the screen. Any way to fix it? my verson is 2015.2.728.45. runtime version is v4.0.30319

Hi Team!

Is there anything I can do to avoid it? Is this a known bug?

Thanks a lot!

hi,

I tried to trigger the event ResizeCompleted on a Custom ganttask. 

I found in the telerik manual (http://docs.telerik.com/devtools/wpf/controls/radganttview/features/drag-and-drop/dragdrop-custom-behaviors.html) the following event : ResizeCompleted(SchedulingResizeState state) – occurs when the resize operation has finished

 

When I try to use it in code, I got it like in the picture! It can't find the override event like explained in the manual. 

 

 

Note: Using version '2015.2.728.40'

How do you use the Quick Start Control ?

Just start with WPF and Telerik so might be going down the wrong road
I have download the Demo's on to my PC and been running them and see example that have usage of telerikQuickStart
I'm guessing that the control is the one that is normaly on the right of most demo's

Have seen that I make a control and ref Quick start
<UserControl ......
             xmlns:telerikQuickStart="clr-namespace:Telerik.Windows.Controls.QuickStart;assembly=Telerik.Windows.Controls">

And seen that you set in your control what you want in the quick start
<telerikQuickStart:QuickStart.ConfigurationPanel>
     <StackPanel Margin="3">
         <Button Content="Button1" Click="OnButton1Handler" Margin="0,2" />
     </StackPanel>
</telerikQuickStart:QuickStart.ConfigurationPanel>

But how do you get one in your application to start ?

 

I'm currently evaluating whether we want to purchase Telerik controls for use in our products. Prototyping is quite cumbersome with the popup's with the message about the trial version.

A semitransparent watermark, or some "trial version" text somewhere in a corner would make it a lot easier for us to do our evaluation. Our business analysts and customers are allergic to popup's (with good reason), so if I would build a demo to show to management then they will not be impressed...

Hello,

I created a GridView that shows a List<object>, this "object" could be several types, all these types inherit from a same type. This base type has 3 properties:Key, Value and Icon.

Now I show my XAML

I attached what it shows at runtime.

The ValueColumn has not the filter control.

The only things is that DataMemberBinding has connected with a Converter because Value property should be several type, but this converter return ever string.

Is it for this reason that not appear a filter control?

This is a converter code (Column of value is not editable)

 

 

Hello Telerik.

I am currently browsing your forums and documentations, looking for two different features for the PDF displayed on my page.

Perhaps you could guide me to the right direction to look.

what i need the PDFViewer to do is:

 

- bookmark each chapter's titles

so that i could add a navigation menu, allowing the user to click a chapter and have the pdf document scrolled all the way down to it.

- implement a toolbox (including a search bar) to ease the user's navigation

 

it is getting pretty annoying finding running examples for these features. if you have something, please let me know.

thank you!
