Gridview with SortDescription doesnot update UI after ItemsSource rebound

Hi,

I am binding my observablecollection to CollectionViewSource which has SortDescriptions. On initial load everything loads fine and sorting can be done.

I have a reset button on which i am trying to refresh the changes in the grid with re fetching observablecollection and binding to ItemSource. Once i do the rebind the sorting doesnot work.

Below is my collectionviewsource,

<CollectionViewSource

x:Key="BuildLineSource"

IsLiveSortingRequested="True"

Source="{Binding BuildLineCollection,

UpdateSourceTrigger=PropertyChanged}">

<CollectionViewSource.GroupDescriptions>

<PropertyGroupDescription PropertyName="BuildLineCategory.Category" />

</CollectionViewSource.GroupDescriptions>

<CollectionViewSource.LiveSortingProperties>

<system:String>ExecutePriority</system:String>

</CollectionViewSource.LiveSortingProperties>

<CollectionViewSource.SortDescriptions>

<componentModel:SortDescription PropertyName="ExecutePriority" />

</CollectionViewSource.SortDescriptions>

</CollectionViewSource>

Below is the code i am calling on Constructor and also on Reset click,

private void GetBuildLines()

{

BuildLineCollection?.Clear();

BuildLineCollection = _buildLineData.GetBuildLines();

((INotifyPropertyChanged)BuildLineCollection).PropertyChanged +=

(x, y) => BuildLineUpdated();

}

ScreenPosition for RadDesktopAlertManager depending on current screen

Hello Télérik,

I'm using a RadDesktopAlert in my software.

The declaration :

private void CreateNotification(string header, string content, int dureeEnMillisecondes, int tailleEnPx)

{

var alert = new RadDesktopAlert();

alert.Header = header;

alert.Content = content;

alert.Opacity = 0.7;

alert.ShowDuration = dureeEnMillisecondes;

alert.Height = tailleEnPx;

alert.ShowCloseButton = false;

//Point pointDeDepart = new Point(0, 20);

RadDesktopAlertManager manager = new RadDesktopAlertManager(AlertScreenPosition.BottomRight);//pointDeDepart);

manager.ShowAlert(alert);

}

- Me, and my clients, using 2 or more screens to work.

- For the moment, i'm using AlertScreenPosition.BottomRight and the notification was displayed in the bottom-right of the main screen (where is the windows task bar), even if the screen software is on a other screen.

I want to know if is it possible to display the notification on the current screen (where is the software, or where is the mouse) ?

Thank you very much, I hope be understadable.

Changing the header color for a RadWindow.Confirm

I would like to change the light blue header color of the RadWindow.Confirm. (See attached)

I have asked this question before and got a satisfactory answer, however that answer no longer works. I get a build error that RadWindow is does not exist in the namespace http://schemas.telerik.com/2008/xaml/presentation

Maybe something changed since I asked this question in 2015.

My current project is using the NoXaml binaries.

WPF RadDesktopAlert with Buttons

Hi Telerik,
I need your quick suggestion on the below requirement for our reputed Client (Transportation domain).
We are using the RaddesktopAlert and have an immediate requirement to have some buttons on RaddesktopAlert to perform some functionalities. I came across that RaddesktopAlert for Winforms supports this but don't have any idea how to achieve the same on RaddesktopAlert for WPF.
Any help on this one will be grateful :)

Data binding ComboBox in GridView

I'm using the combobox in this example inside a grid as a celledittemplate:
<telerik:GridViewDataColumn Header="َArticle Description" Width="100"><telerik:GridViewDataColumn.CellTemplate><DataTemplate><TextBlock Text="{Binding DataContext.AccDocumentItem.Description1, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"/></DataTemplate></telerik:GridViewDataColumn.CellTemplate><telerik:GridViewDataColumn.CellEditTemplate><DataTemplate><telerik:RadComboBox IsEditable="True" DisplayMemberPath="SLStandardDescriptionTitle"ItemsSource="{Binding DataContext.AccDocumentItem.SelectedSL.SLStandardDescriptions, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"Text="{Binding DataContext.AccDocumentItem.Description1,Mode=TwoWay,RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"><i:Interaction.Triggers><i:EventTrigger EventName="DropDownOpened"><i:InvokeCommandAction Command="{Binding DataContext.SLStandardDescriptionsDropDownOpenedCommand, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}" CommandParameter="DLType2"/></i:EventTrigger></i:Interaction.Triggers></telerik:RadComboBox></DataTemplate></telerik:GridViewDataColumn.CellEditTemplate> </telerik:GridViewDataColumn>

I need to present a grid where one column is a combobox. The user can select one value from the list or enter a new value, the problem is that selected row is repeated in all rows. Can you please tell me what I'm doing wrong?
Your time much appreciated!

How to make InlineUIContainer ReadOnly?

Hi every body...

In my application I have to make an InlineUIContainer (inserted within a table) as ReadOnly. To achieve this requirement I tried ReadOnlyRangeStart and ReadOnlyRangeEnd (as shown in the attached code). I also tried to InsertReadOnlyRange around the table using DocumentPosition (not shown in the attached code). In both cases the following error is thrown:

"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll"

Is not possible to make InlineUIContainer as ReadOnly? If so; is there any workaround?

Any Help Will Be Greatly Appreciated...

Note: the cause why I used TextBlocks instead of just adding new span to the paragraph; is that I have to make Text and image tightly grouped together; so that if they come across end of the page (and there is no enough space to them), then they move together to a new page. If there is a better solution to this requirement, it will be welcomed.

Private Function GetCenterManagerTable(ByVal mainDocument As RadDocument, ByVal FMMSContext As FMMS.BusinessObjects.Models.FMMSEntities) As Table

Dim _table As New Table With {.Borders = New TableBorders(New Model.Border(1, BorderStyle.Single, Colors.Black)),

.FlowDirection = GetFlowDirection(),

.PreferredWidth = New TableWidthUnit(TableWidthUnitType.Fixed, mainDocument.SectionDefaultPageSize.Width - 115),

.HorizontalAlignment = RadHorizontalAlignment.Center,

.Tag = RequestTypes.WritingDraft}

Dim _cellReviewer As New TableCell With {.TextAlignment = RadTextAlignment.Center,

.Tag = RequestTypes.WritingDraft}

QueryableCollectionView item type

When using QueryableCollectionView, it takes an IEnumerable as source. Are there any further requirements on the type of the individual items?

My input data is an object-array, and in the code I'm currently investigating a DataTable is created and its DefaultView is used as input to the QueryableCollectionView. I was wondering if I could just skip the DataTable and just use a List<object[]> instead. Apparenty not, but I'm curious as to why?
