Hi,
Problem:When I lick on button outside the grid only on second click I get data? why?
var historyReportViewModel = new HistoryReportViewModel();
var historyReportResults = historyReportViewModel.CreateHistotyReport(resultsSelection, portalSelection, fromDateTimeSelection,
selectionTypeSelection, routeSelection, toDateTimeSelection);resultsDataGrid.ItemsSource = historyReportResults;
<telerikDataGrid:RadDataGrid Grid.Row="4" Grid.Column="0" x:Name="resultsDataGrid" Margin="10"
AutoGenerateColumns="False">
<telerikDataGrid:RadDataGrid.BindingContext>
<local:HistoryReportViewModel />
</telerikDataGrid:RadDataGrid.BindingContext>
<telerikDataGrid:RadDataGrid.Columns>
<telerikDataGrid:DataGridTextColumn PropertyName="Succeded" HeaderText="Succeded"/>
<telerikDataGrid:DataGridTextColumn PropertyName="Type" HeaderText="Type"/>
<telerikDataGrid:DataGridTextColumn PropertyName="EndTime" HeaderText="End Time"/>
<telerikDataGrid:DataGridTextColumn PropertyName="File" HeaderText="File"/>
<telerikDataGrid:DataGridTextColumn PropertyName="Route" HeaderText="Route"/>
<telerikDataGrid:DataGridTextColumn PropertyName="FailedFolder" HeaderText="FailedFolder"/>
<telerikDataGrid:DataGridTextColumn PropertyName="Portal" HeaderText="Portal"/>
</telerikDataGrid:RadDataGrid.Columns>
</telerikDataGrid:RadDataGrid>
I cannot reproduce the issue.
Here is my xaml:
<Grid RowDefinitions="Auto,*"> <Button Text="Add Data" Clicked="Button_Clicked"/> <telerikDataGrid:RadDataGrid x:Name="dataGrid" Grid.Row="1" AutoGenerateColumns="False"> <telerikDataGrid:RadDataGrid.Columns> <telerikDataGrid:DataGridTextColumn PropertyName="Name" HeaderText="Name"/> <telerikDataGrid:DataGridNumericalColumn PropertyName="StadiumCapacity" HeaderText="Stadium Capacity"/> </telerikDataGrid:RadDataGrid.Columns> </telerikDataGrid:RadDataGrid> </Grid>the viewmodel and data model:
public class ViewModel { public ViewModel() { this.Items = new ObservableCollection<Club> { new Club{ Name = "AAAAA"}, new Club{ Name = "BBBBB"}, new Club{ Name = "CCCCC"}, new Club{ Name = "DDDDD"}, }; } public ObservableCollection<Club> Items { get; set; } } public class Club : INotifyPropertyChanged { private string name; public string Name { get { return this.name; } set { if (this.name != value) { this.name = value; OnPropertyChanged(); } } } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } }and the button clicked event in page's code behind::
public partial class MainPage : ContentPage { ViewModel vm; public MainPage() { InitializeComponent(); this.vm = new ViewModel(); this.BindingContext = vm; } private void Button_Clicked(object sender, EventArgs e) { this.dataGrid.ItemsSource = this.vm.Items; } }The result:
You have to debug the code on your side and check when the DataGrid.ItemSource is populated with data.
I hope this information will be of help.
