When you edit a value of a certain item of the DataGrid and keyboard is displayed, while the focus is still in the input and the row is scrolled away, the keyboard will stay open on Android.
In addition, if you return back to the edited cell, the row will display as if it were on focus, the cell shows the editor underline, the keyboard is still open, but there will be no focus. You will be required to click on the cell to get focus again.
Lastly, only on Android 5.1, if the edited value is a number, when you scroll the cell out of view, the keyboard changes from the numerical to alphanumerical (default).
You can reproduce this by changing input language to any region that uses a comma decimal separator (e.g. Duetsch). The comma is ignored, ultimately corrupting the data
Step 1 - File > New > LoadOnDemandCollection Demo
Follow the LoadOnDemandCollection documentation https://docs.telerik.com/devtools/xamarin/controls/datagrid/load_on_demand#loadondemandcollection
Step 2 - Deploy to UWP
=> Observe the DataGrid will be stuck in busy state after the initial set of items load
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.
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)
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.
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 starting an app that contians a RadDataGrid in the initial page, an exception is thrown because the telerikfont.ttf file is left unregistered.
Access anything from the TelerikFont class before the InitializeComponent of the page:
Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.
