I added showrowheader to true for my application, and now I am getting this error -
System.NullReferenceException: 'Object reference not set to an instance of an object.'
This exception was originally thrown at this call stack: Syncfusion.UI.Xaml.Grid.DataRow.UpdateRenderer(Syncfusion.UI.Xaml.Grid.DataColumnBase, Syncfusion.UI.Xaml.Grid.GridColumn) Syncfusion.UI.Xaml.Grid.DataRow.UpdateColumn(Syncfusion.UI.Xaml.Grid.DataColumnBase, int) Syncfusion.UI.Xaml.Grid.DataRow.EnsureColumns(Syncfusion.UI.Xaml.ScrollAxis.VisibleLinesCollection) Syncfusion.UI.Xaml.Grid.RowGenerator.EnsureColumns(Syncfusion.UI.Xaml.ScrollAxis.VisibleLinesCollection) Syncfusion.UI.Xaml.Grid.VisualContainer.EnsureItems(bool) Syncfusion.UI.Xaml.Grid.VisualContainer.MeasureOverride(System.Windows.Size) System.Windows.FrameworkElement.MeasureCore(System.Windows.Size) System.Windows.UIElement.Measure(System.Windows.Size) System.Windows.ContextLayoutManager.UpdateLayout() System.Windows.ContextLayoutManager.UpdateLayoutCallback(object)
Can someone please help me fix this error so I can add a row header to my sfdatagr
This seems to be erroring after I do a RefreshColumns() method.
