TapGestureRecognizer not working correctly when tapping inside the DataGrid control on iOS and MacCatalyst platforms.
Workaround:
You could use CellTap or CellDoubleTap commands of the DataGrid control. Here are the links to our documentation articles: DataGrid Commands and DataGrid CellTap Command.
Hello,
it would be a very useful information when subscribing to the DataBindingComplete Command of a DataGrid to know whether for example a filter, sort, grouping had changed.
Currently, it is an internal Property
{
public IDataViewCollection DataView { get; internal set; }
internal DataChangeFlags ChangeFlags { get; set; }
internal DataBindingCompleteEventArgs()
{
}
}
Regards
DataGrid is added inside pages that can be accessed through shell flyout menu.
And the exact steps to reproduce the issue:
Go to page GridOne page in flyout menu.Enter any element by double tap. this navigates to another page - SubGridPage
On SubGridPage again double tap any element. this navigates to another page - InnerModel
When you are in InnerModel page select from flyout menu GridTwo page
On GridTwoPage double tap any element, this navigates to another page - SubGridPage
On SubGridPage double tap any element. this navigates to another page - InnerModel
When you land on InnerModel page go back to Grid One on flyout menu.
When you are in the GridOne InnerModel, press the back arrow.
It navigates to the SubGridPage. but the DataGrid is not visualized.
Currently I can change the IsBusy background color by using implicit style:
<ContentPage.Resources>
<ResourceDictionary>
<Style TargetType="telerik:RadBusyIndicator" x:Name="busy">
<Setter Property="BackgroundColor" Value="Red"/>
</Style>
</ResourceDictionary>
</ContentPage.Resources>
<telerik:RadDataGrid IsBusy="True"/>
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.
Provide a user commands as RadListView that you could directly bind in the ViewModel.
Solution:
Enhance the DataGridCommand class as a user command and in this way bind it to the defined commands inside ViewModel/ContentPage. - Sample project attached
When navigating to DataGrid examples, xaml binding errors occur for ActualWidth and Header Text.
Still, the app runs as expected.
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);
Provide an option to sort the template column by nested property.
For example:
<dataGrid:DataGridTemplateColumn>
<dataGrid:DataGridTemplateColumn.CellContentTemplate>
<DataTemplate>
<Label Text="{Binding MyAddress.City}" />
</DataTemplate>
</dataGrid:DataGridTemplateColumn.CellContentTemplate>
<dataGrid:DataGridTemplateColumn.SortDescriptor>
<dataGrid:PropertySortDescriptor PropertyName="MyAddress.City" />
</dataGrid:DataGridTemplateColumn.SortDescriptor>
</dataGrid:DataGridTemplateColumn>
