Deactivating MasterDetail View in Runtime

[Patrick]

Dear Support

How can I deactivate the MasterDetail View in Runtime. Activating works fine, but on deactivating, the Relations are still there and shown in the Datagrid with a plus...

void ToggleMasterDetailView(object sender, RoutedEventArgs e)
{
    //BUG: Deactivating Master Detail View does not work
    
    var tmpItemSource = MainDataGrid.ItemsSource;
    MainDataGrid.ItemsSource = null;
    MainDataGrid.AutoGenerateRelations = !MainDataGrid.AutoGenerateRelations;
    MainDataGrid.ItemsSource = tmpItemSource;
}

Hi Patrick,

Thank you for contacting Syncfusion Support.

Your requirement can be achieved by setting null value for DetailsViewDefinition property in SfDataGrid. Please refer the below code snippet, 

private void btnItemSource_Click(object sender, RoutedEventArgs e) 

{ 

            var tmpItemSource = dataGrid.ItemsSource; 

            dataGrid.ItemsSource = null; 

            dataGrid.AutoGenerateRelations = !dataGrid.AutoGenerateRelations; 

            dataGrid.ItemsSource = tmpItemSource; 

            

            //set null value for the child DataGrid 

            dataGrid.DetailsViewDefinition = null; 

}

Please let us know if you have any concerns in this.

Hi Vijayarasan

Gives me an errer on Toggle back to the AutoGenerateRelations=True.

"An Element with the same key was already added"
