Hi there,

Does anyone know how we can have an endless horizontal scrolling? Basically, I want to be able to change the visible range of ganttview dynamically as user clicks on the right/left thumb of horizontal scrolling.

Thanks,

Hello,I have a requirement that set the visibility property to collapsed of the ListRootContainer which in the Radtreeview control 

So, what should I do? Or some way to make the ListRootContainer hide.

Hi,

The RadDocking.Close event is not fired when close the pane with mouse middle button (click by pane header), how to get it raised?

Thank you.

Hi, I've got a grid where one of my columns shows an alphanumeric id and I want to sort the numbers correctly so I've implemented manual sorting. The bound data comes from a DataTable so I don't have a viewmodel for the rows. My sorting code, which I've hooked up to the Sorting-event, looks something like this:

But I have two issues:

1. When sorting on several columns I want to manage the sorting indices showing in the column headers, but I don't know how. It seems like they correspond to what's in the SortDescriptors collection. But I can't really edit the descriptors without adding some other sorting, can I? Is there some way to manually update the indices? Or set the SortDescriptors without really add another sort.
2. We can store the state of grids to user-defined views, and do this by using the PersistenceManager to get xml describing the state of the grid. But since the sorting is defined by the SortDescriptors collection our manually sorting is not exported to xml.

I guess that both problems is about how I should edit the SortDescriptors when using the Sorting event.

I want to remove the "Select All" option from multi select check box filter in kendo grid view, when there is no data to be shown on UI or when grid is empty.

Any setting i can do to do so?

Hello

We are facing the challenge, to present tasks to our customers.
Each task can consist out of n tasks, but can also stand alone. These child-tasks should be displayed in a hierarchical manner and must be searchable (down to the tree-leaves).

Now we have been wondering if it's easier to build a hierarchy in a GridView, where the Search is implemented, or use the TreeListView, which meets our hierarchical needs.
Since the hierarchical GridView creates new Grids for each hierarchy-level, it seems quiet challenging for me, too.

For the TreeView, you are providing an search-example:
https://docs.telerik.com/devtools/wpf/controls/radtreeview/how-to/implement-search-filter-sort
can this be adopted for the TreeListView?
I'm also wondering, if the search-box from GridView is accessible somehow in the TreeListView somehow.

So our main-concern is, which control is the way to go?

We are grateful for any advice you can give us.

Best Regards

Nico

Hi,

I'm currently setting my ItemsSource for my RadGrid to be of type QueryableCollectionView

I also set the selecteditem to be of type IDTO. 

When I use an QueryableCollectionView, by default, SelectedItem is set to the first item in the collection. If I were to use an ObservableCollection, it's completely fine, SelectedItem is empty until an item is selected. May I ask how do I set it so the QueryableCollectionView doesn't set the value by default. 

Hi Team,

I am facing an issue with Ribbonview during design time I can not see the ribbon control.

Scenario:

I have created a user control as a container for my Ribbonview. During design time we need to specify the height of that container user control to more than 250 like 251 in order to see this control during design time.

<telerik:RadGridView.FilterDescriptors>   

     <telerik:CompositeFilterDescriptor LogicalOperator="Or">       

          <telerik:CompositeFilterDescriptor.FilterDescriptors>             

               <telerik:FilterDescriptor Member="Hardcoded" Operator="IsEqualTo" Value="false"/>        

          </telerik:CompositeFilterDescriptor.FilterDescriptors>   

     </telerik:CompositeFilterDescriptor>

</telerik:RadGridView.FilterDescriptors>

When the editor becomes active, the contextualgroup IsActive is set to true and RibbonTab appear visible. When user selects it, it looks like in "before" picture. Everything ok. But when in this time the editor is closed, IsActive is set to false, but no other RibbonTab is automatically selected and in appears like in "after" picture. In the samples, i have not seen any special source code to select to another RibbonTab in this case. What is necessary to do in this case and how to define RibbonTab to be selected when ContextualGroup.IsActive is set to false?

Thanks, Ivo Kovacka
