When starting a cell edit, it is desired to have all the text selected, so the user can easily replace the current text without having to delete it. 

If you define a PropertyGroupDescriptor in XAML or in page constructor and the PropertyName is set to a nested property, the grouping is not applied.

Grouping by a nested property works correctly when called from the Filtering UI or on a button click action.

I have designed  datagrid like weekly signin details
But i required datagrid with sub header like , 
Please provide better solution to design for sub header with main header

 

Add the ability to specify a Template that should be shown when the DataGrid is empty.

Refer to the attached reproducible.

1. Run app and apply a filter: "Contains 0"

2. Notice #40 is in the correct location, between #30 and #50

3. Press the button on the bottom of the page to go BlankPage and then navigate back.

4. Observe #40 is now at the end of the rows even though the filter is clearly applied.

Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed.  I can reproduce the problem with both Replace and Add+Remove operations.

public override void OnNavigatedTo(INavigationParameters parameters)
{
    base.OnNavigatedTo(parameters);

    if (!parameters.ContainsKey("from"))
    {
        var items = new ObservableCollection<MyModel>();
        for (var i = 1; i <= 100; i++)
            items.Add(new MyModel { Number = i.ToString() });
        Items = items;
    }
    else
    {
        var item = Items[39];

        // Bug Test #1 - using ObservableCollection Reset
        Items[39] = item;

        // Bug Test #2 - using ObservableCollection Remove & Add
        //Items.RemoveAt(39);
        //Items.Insert(39, item);
    }
}

Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled. 

when using automatic column generation you don't have easy access to the column being created so that you can apply customizations (Header, style, etc).

Please implement the same event that UI for WPF has, see it here: https://docs.telerik.com/devtools/wpf/controls/radgridview/events/column-resize-event#autogeneratingcolumn

I have tried to change the cell background color programatically .

This is Perfectly Working on Android Devices.

But,this not working on iOS devices.

Please provide better solution to solve this issue.

below i have attached the xmal and .cs file

When the DataGridPickerColumn ItemsSource property is bound to a collection not part of the business object used for the DataGrid, and ItemDisplayBindingPath is used, null reference exception is raised when selecting items in the picker.

When display is on high resolution screen (MS surface book screen 3000*2000 with 200% scale) the DataGrid is not resized correctly.  See attachments. 

Applying custom filter to the datagrid and removing column at the same time disables the horizontal scrollbar - in scenario when the content of the column is bigger than the screen size.

Provide a way to associate a FilterDescriptor with a TemplatedColumn

While changing the orientation on mobile device to portrait or landscape, the columns' size is not calculated properly and the columns overlap on one another.

When the UserSortMode is set to single and it is sorted by a Template column that has DelegateSortDescriptor when we tap on another column the SortDirection of the Template is still visible.

Currently in 2019 R2 and earlier, the "options" button at the bottom of the filtering UI allows the user to rearrange and toggle the visibility of columns in the DataGrid.

I request to have a property or setting on the DataGrid or the DataGridColumn that will prevent the user from changing the visibility or ordering of columns. from that UI (just like you can prevent user filtering or user sorting)

If there a components which handles the Tap gesture (e.g. a button) is inside the TemplateCell, the DoubleTap gesture of the RadDataGrid throws NullReferenceException.

when the LoadOnDemand mode is set to Automatic and there are no more items for loading, the automatic load on demand is called

After scrolling down enough times where all of the data is loaded, if I try to scroll a bit more, things go a bit crazy.  A loading icon flickers on and off over the grid; the data in the grid flickers away and then back; and the entire UI essentially gets stuck in this situation.

QSF DataGrid CRUD example
When editing the value inside the OrderDate column, the edited value is not presented in the OrderDate column. It keeps the old value

When starting an app that contians a RadDataGrid in the initial page, an exception is thrown because the telerikfont.ttf file is left unregistered.

Work-around:

Access anything from the TelerikFont class before the InitializeComponent of the page:

TelerikFont.GetUseEmbeddedFont(this);
