When a Picker is used in a CellEditTemplate, and when in edit mode, when I click on the arrow of the Picker - the picker does not open. It only opens of I click the text in the Picker.

        <DataTemplate x:Key="template1">
            <Picker ItemsSource="{Binding Item.Categories}" />
        </DataTemplate>

        <telerik:RadDataGrid x:Name="dataGrid"
                             AutoGenerateColumns="False">
            <telerik:RadDataGrid.Columns>
                <telerik:DataGridTextColumn PropertyName="Name" />
                <telerik:DataGridTextColumn PropertyName="Category" CellEditTemplate="{StaticResource template1}" />
            </telerik:RadDataGrid.Columns>
        </telerik:RadDataGrid>

A work-around is to not use a Picker, but use a RadComboBox.

Hi Team,

I would like to be able to programmatically invoke a ToolTip on a specific cell.

It would be great if you were able to allow us to use a DataGridCellInfo item and string or View content for the tooltip (like UI for WPF allows)

var cellInfo = new DataGridCellInfo(rowToSelect, columnToSelect);

// Option 1 - Quick and easy
var stringContent = "I'm a tooltip";
MyRadDataGrid.ShowTooltip(cellInfo, stringContent);


// Option 2 - For everyone who needs more than just a string.
var customContent = new HorizontalStackLayout();
customContent.Children.Add(new Image{ Source = new FileImageSource{File = "warning.png"}});
customContent.Children.Add(new Label{Text = "I'm a tooltip"});

MyRadDataGrid.ShowTooltip(cellInfo, customContent);

I have a DataGrid with ItemsSource bound to ObservableRangeCollection,
First I Clear() the existing items of the collection, then add new items, and raises a single CollectionChanged event with action = NotifyCollectionChangedAction.Reset.

the grid continues to show nothing.

This works with .NET MAUI CollectionView and ListView

Workaround: Add a delay after clearing the collection.

Hi Team,

Please refer to the following screenshot from the ControlsSamples project on Windows:

Notice the descender on the y character is pushing up the Delivery column header's Label container, but the Price text is flush with the bottom? This is causing misalignment between text in other column headers that do not have descenders.

You might not immediately notice this, for example in the Aggregates demo, only the first column has no descenders but the next two do. 

However, it's a more serious visual problem when every other column is vertically offset. Please consider adding a default Padding to account for descenders, or maybe change the VerticalOptions of the text container to be center aligned.

Thank you,

Matthew & Team

When the selected item is set initially, the selected style is not applied to the row/cell.

Workaround: You can use a Dispatcher to workaround the issue, code looks as follows:

this.Dispatcher.StartTimer(TimeSpan.FromMilliseconds(200), () =>
        {
            if (dataGrid.SelectedItem == null)
            {
                dataGrid.SelectItem(viewModel.PersonCollection.First());
            }
            return false;
        });

1. filter the column by any distinct value
2. The filter is applied
3. Open the same filtering again and tap reset
4. All rows are visible and everything is ok
5. Open the same filtering again

The Checkbox from step 1 is still checked and checking any other checkbox and applying filtering does not work 

.Net Maui Data Grid Property Aggregator Descriptor incorrect placement on Mac

IsCaseSensitive property doesn't work in the DataGrid control.

Workaround: Use Programmatic Filtering 

Example: https://github.com/telerik/maui-samples/tree/main/Samples/SdkBrowser/Examples/DataGridControl/FilteringCategory 

Disable the built in filtering UI and apply a custom UI with programmatic filtering.

Run SDKBrowserMaui example on WinUI
Navigate to DataGrid->LoadOnDemandCategory->LoadOnDemandExmaple

Start scrolling the grid using the scrollbar

Crash occurs on WinUI.

.Net Maui Data Grid Property Aggregator Descriptor disappears when displaying columns in the same data grid which doesn't have aggregate property set

Hi Team,

I would like to be able to obtain a reference to a data item in the DataGrid when another UI element (outside of the DataGrid) is dragged and dropped onto it.

This feature request is to add the plumbing necessary to achieve that.

Thank you,

Tony
