I have a SfDataGrid.

Usually "Children" property is empty ObservableCollection<...>
And expand-marker is hidden (HideEmptyGridViewDefinition="True");
But sometimes some entities was added in "Children".
And expand-marker is stay be hidden((( And it's appears only when I scroll or resize window (grid).
Can I invalidate grid in this case? Or can I swich some property that grid was updating properly?

<sf:SfDataGrid x:Name="grid"
                   ItemsSource="{Binding Items}"
                   HideEmptyGridViewDefinition="True"
                   ShowGroupDropArea="False"
                   AllowEditing="True">
        
        <sf:SfDataGrid.Columns>
            ...
        </sf:SfDataGrid.Columns>
        <sf:SfDataGrid.DetailsViewDefinition>
            <sf:GridViewDefinition RelationalColumn="Children">
                <sf:GridViewDefinition.DataGrid>
                    <sf:SfDataGrid x:Name="FirstDetailsViewGrid">
                        <sf:SfDataGrid.Columns>
                            ...
                        </sf:SfDataGrid.Columns>
                    </sf:SfDataGrid>
                </sf:GridViewDefinition.DataGrid>
            </sf:GridViewDefinition>
        </sf:SfDataGrid.DetailsViewDefinition>
    </sf:SfDataGrid>

Hi Pavel,

 

Thanks for using Syncfusion products,

 

We have analyzed your query. We are able to reproduce the reported issue by not refreshing UI when adding the ItemSource to the children. However, you can meet your requirement  by writing the UpDateDataRow() method when calling the ItemSource. Please find the following code snippet to illustrate this:

 

Code Snippet [ Xaml]:

 

 

using Syncfusion.UI.Xaml.Grid.Helpers;

 

this.dataGrid.UpdateDataRow(rowIndex);

 

 

Please let us know if you need further assistance,

 

Thank you,

Jai Ganesh S
