Hey,

I have the problem with a gridview. When I cancel the Rowedit with pressing 'Esc' two times the row not fully cancels. As you can see in my video.

(https://www.dropbox.com/s/ctpiyfsq0v3vyx2/Record100919.wmv?dl=0)

The previously in the same row entered value is still visible. As soon as you click in the cell, it disapears. If  I not click into it and change another cell, it even writes the before cancelled value into the cell.

I not have something really special there. The radgridview itemsource is a Datatable set in C#:                

rgvTeile.ItemsSource = Daten.GibTeileWithReklamationsID(aktReklamationsID).DefaultView;

This is my radgridview:

                            <telerik:RadGridView
                                Grid.Row="3"
                                x:Name="rgvTeile"
                                Margin="0 10 0 0"
                                AutoGenerateColumns="False"
                                GroupRenderMode="Flat"
                                ShowGroupPanel="False"
                                FilteringMode="Popup"
                                ShowSearchPanel="False"
                                ValidatesOnDataErrors="InEditMode"
                                EnableColumnVirtualization="False"
                                NewRowPosition="Bottom"
                                HorizontalAlignment="Left"
                                RowEditEnded="RgvTeile_RowEditEnded"
                                ActionOnLostFocus="CommitEdit"
                                >
                                <telerik:RadGridView.Columns>
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding ID}"
                                        Header="ID"
                                        IsVisible="False"
                                        IsReadOnly="True"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Menge}"
                                        Header="Menge"
                                        />
                                    <telerik:GridViewDataColumn

                                        Header="Bezeichnung"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding ArtikelNummer}"
                                        Header="ArtikelNummer"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Farbe}"
                                        Header="Farbe"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Fertigmaß}"
                                        Header="Fertigmaß"
                                        />
                                </telerik:RadGridView.Columns>
                            </telerik:RadGridView>

Hi,

I have a RadTreeMap that's working perfectly except that I want its labels to be centered vertically and horizontally within each rectangle.

I'm also using a Colorizer:

<telerik:TypeDefinition.Mappings>
      <telerik:DesaturationColorizer From="1" To="0.1" StartColor="#d9ac26"/>
</telerik:TypeDefinition.Mappings>

...so, when I attempt to change use a TextBlock with the proper alignment:

<Style TargetType="telerik:RadTreeMapItem">

     <Setter Property="Template">
           <Setter.Value>
                <ControlTemplate>
                     <TextBlock Text="{Binding Label}" HorizontalAlignment="Center"  VerticalAlignment="Center"/>
                 </ControlTemplate>
            </Setter.Value>
       </Setter>
</Style>

...it successfully centers the labels, but I lose the colorizing effect. How can I make the TextBlock respect the intended colorizing?

As I see when RT control import and export back, it cleans custom attributes.

id tag is required for styles as i understand, but what about my own attribute "data-id" (by html specification all data-* attributes are user defined attributes)?

Is it any solution to prevent remove user custom attributes?

Hello 

Is it possible to do a datareduction so we dont display all the points : Handle
one million points (5 series of 200 000), and display one point by pixel (with
only the maximum level for each pixel. So one million points are never
displayed at the same time and we do datareduction.

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
