RadGridView RowDetailTemplate Child Grid Missing Column Values Until Window Resize

Hi,

I have a RadGridView that has a RowDetailTemplate that we are using a listbinding to show another grid showing details associated with the parent row item.

I'm setting RowDetailVisibilityMode to Visible to show the nested RowDetailTemplate expanded by default. All of this data is loaded from a monolith API call and then held in memory.

We are using an ICollectionView to filter the parent grid using fields in the UI.

This all works, BUT when the filter is released using a command and the entire grid is restored from the collection in memory, the child (RowDetailTemplate) grid only shows the values in the first column of the grid rows. The others don't show up unless I resize the App window, then they all show up.

So, I know the data is there, but it's not showing up without resizing the window after we restore the collection.

Is there a known issue with this behavior or a setting that I can apply to either the parent or child grid that will force the column values to re-render in the UI?

Behaves weirdly.
Awaiting for the solution.

WPF Telerik RadRichTextBox cannot display italic fonts

Hello,

I'm using RadRichTextBox (WPF Telerik 2021.1.222.40) and get an error about my span's font can't cannot be italicized. From what I'm investigating, it seems like my FontFamily is specifying the style so I can't reassign the FontStyle. Some fonts where I am experiencing this problem: ＭＳ明朝 Regular, ＭＳＰゴシック Regular, A-OTF 新ゴ Pro B, A-OTF 新ゴ Pro EL... I assume it has to do with the suffixes behind the font names: Regular, B, EL

Has anyone else encountered this issue?

Thanks for your help.

I want to automatically put the card in edit mode when the user adds a new card

I don't see an easy way to do this. I Selected the added item in the view model and then sent a message to the view to get it to call the Begin Edit method, but that didn't cause the card to go into edit mode.

Even though I added an item to the list that was bound to the Items source of the RadCardView, I noticed when I made the below call (from the view code behind), the list of cardViewItems did not contain the newly added object that I added to the source. Not sure why it is not automatically updating the cardviewitems, as the itemsSource is bound to an Observable Collection.

IEnumerable<RadCardViewItem> cardViewItems = cardView.ChildrenOfType<RadCardViewItem>();

I think that when BeginEdit is called, it is not finding the CardViewItem and therefore it does nothing. Not sure how to fix that. Maybe there is a bug in the cardview class.

Add new detail record in MasterDetail RadGridView

Hi,

I am trying to add new record into Details in Master Details RadGridView (Based on Telerik Demos/GridView/Editing/Entity Framework CRUD). I added option to add new detail record into master, in row details grid view new row with message "Click here to ad new item" appeared. After clicking on message an filling data in GridViewAddingNewEventArgs, I see new record in the details, but when I try to save it with dbContext.SaveChanges(), I've got message in output window about SQL update statement instead of insert (I always got the EntityFrameworkCore.DBUpdateConcurrencyException).

GridView with Dynamic ComboBox Column Header

Hello, Telerik

I want to create a feature with the following characteristics:

1. Use of the MVVM pattern.
2. The number of columns in the DataGridView is not fixed but dynamic. (Users can specify the number of columns as an option, allowing for dynamic changes.)
3. Only the first column's text is fixed, while the 2nd to nth columns are ComboBoxes, allowing users to select which columns they want to view.

For example, if a class has (name, age, gender, department, major, student number, average grade, highest grade, lowest grade) as fields,
'Name' is always shown in the first column as fixed data.
'Age' to 'Lowest Grade' are available as ComboBox options for users to select and view as they wish.

If n = 5, it could be displayed as follows:

1st | 2nd | 3rd | 4th | 5th
Name (Fixed) | Age | Gender | Major | Avg Score

<telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="column 1" DataMemberBinding="{Binding data_1}"/>
                <telerik:GridViewDataColumn Header="column 2" DataMemberBinding="{Binding data_2}"/>
                <telerik:GridViewDataColumn Header="column .." DataMemberBinding="{Binding data_1}"/>
                <telerik:GridViewDataColumn Header="column n" DataMemberBinding="{Binding data_n}"/>

</telerik:RadGridView.Columns>

I searched all the SDK examples and forums, but I don't know how to write it.

Thank you in advance.

Selecting Step in code behind for RadStepProgressBar by Binding - No Visual Update

Hi, we are looking at using the RadStepProgressBar

in Xaml

  <telerik:RadStepProgressBar
x:Name="SystemStepProgressBar"
ItemsSource="{Binding Steps}"
SelectedItem="{Binding SelectedStep, Mode=TwoWay}">

We are binding to a collection of StepInfo as per example online

When we change the SelectedItem in code behind, this is not registering visually, even though the RadStepProgressBar.SelectedItem and SelectedIndex is as we expect the visual display does not change?
