Hi, 

I am using the RadTileView to load photos and I set the dragmode to slide, but what happens was, when you drag a photo into a different position the other photos moves in different direction as long there is a vacant slot. Is there a way to control the movement of the other objects(photos) in one direction? let say move side ways going to the right.

 

Thank you

Hello,

I have an application that follows the MVVM pattern that contains data presented in different RadGridView items.

My grids are bound to different QueryableCollectionViews exposed as IEnumerable properties in a view model.

Lets say I have a refresh-button that grabs data from a webapi and I want to update the grids with it.
Is there a way to refresh the QueryableCollectionView with the data without loosing filters, groupings etc?

Today I re-create my QueryableCollectionViews and manually add possible filters etc. The issue I'm having right now is that while the filters do work, the funnel icons for the filtered columns does not light up, so the client might not realise the grid is filtered.

 

Is there an easy way around this?

Thanks in advance,
Fredrik

To bind the IsExpanded Property to my own IsExpanded property I use the following snippet:

<Style TargetType="{x:Type telerik:RadTreeViewItem}" x:Key="ItemContainerStyle"  >
    <Setter Property="IsExpanded" Value="{Binding Path=IsExpanded,Mode=TwoWay}"/>
</Style>

This works fine so far but the highlight color of the nodes turned from blue into grey. How can I keep the original style and only add the setter property?

I can't find a way to clear selected items when RadAutoCompleteBox SelectionMode is set to "Multiple". I don't want to re-instantiate a new one just to clear selections.

I have DragAndDrop enabled on a RadGridView. This works, but when I want to scroll or I try to resize the column header a dragAndDrop action is also started that prevents the scrolling or resizing.

How can I detect that the DragAndDrop event started on a scrollbar or a column header and stop the event?

Solutions I found on the telerik page are all with the old RadDragDropManager and not with the DragDropManager that should now be used. I can't find the equivalent function for e.GetElement<T> that was called on the  in the DragDropQueryEventArgs. This would be called in the DragInitializeHandler.

Please give me solution to fix these issues regarding to GridView .

I use the Telerik libraries 2014.2.811.45.

I have a tree which can be edited by the user. The user as well can adjust the width of the tree and make it narrow enough to cut off some of the node names.

This post here (http://www.telerik.com/forums/treeview-tooltips-instead-of-horizontal-scroll-bar) seems to solve the problem but is unfortunately outdated. The API has changed meanwhile - the functions/properties don't exist any more.

Still I tried to adjust the solution to my library version but I couldn't get it work. The solution gets the bounds of the tree and each of its items and compares them. This seems to be an easy and adequate solution which I would like to use as well. Trying out different properties showed me the following: Width seems to return NaN. ActualWidth seems to return pretty much the width of the tree whether it is called on the tree or the node. I would expect it to return the width of the node name if called on the node. Further I could not find a property to get the right border of the tree/items.

How can I solve this problem with my telerik libraries?

Hi, we are evaluating DevCraft - the most critical portion that will affect our decision is the 3D charts functionality in WPF for our software. I used the WPF sample code in this https://github.com/telerik/xaml-sdk/tree/master/ChartView3D/WPF and successfully created a Surface Plot with colorizer.

 

Yet no matter what I do I cannot get the Tooltips to work - Tooltips are critical for our functionality and we need to show the datapoint that is closest in the surface plot in order to satisfy our need. 

I followed the directions in http://docs.telerik.com/devtools/wpf/controls/radchartview3d/features/behaviors/tooltipbehavior3d with no success.
 
The code below is my modified version of the code in the github to add tooltips.

https://github.com/telerik/xaml-sdk/blob/master/ChartView3D/WPF/ValueGradientColorizer/SurfaceGradients.xaml

 

I am using this project in Windows 10 professional with Telerik UI for WPF version 2017.2.629.0

A quick response would be appreciated since I will have to present a report tomorrow comparing Telerik with alternative 3D visualization libraries. 

Kind regards
