Stacked Header Hight changes unexpectedly


How to fix this "staircase" effect? (I want all of the stacked headers to be at the same height)



<Syncfusion:SfDataGrid x:Name="resultGrid"
                                                       Margin="0,3, 7, 0"
                                                       ItemsSource="{Binding AnalysisResultRows}"

.xaml.cs (code behind):

if (null != DataContext)
    AnalysisResultViewModel viewModel = (AnalysisResultViewModel)DataContext;

    resultGrid.Columns.Add(new GridTextColumn()
        HeaderText = "File Name",
        MappingName = "FileName",

    resultGrid.Columns.Add(new GridTextColumn()
        HeaderText = "Filter",
        MappingName = "Filter",

    resultGrid.Columns.Add(new GridNumericColumn()
        HeaderText = "Intensity",
        MappingName = "Intensity",

    for (int i = 0; i < viewModel.SensorNames.Count(); i++)
        resultGrid.Columns.Add(new GridNumericColumn()
            HeaderText = "Intensity",
            MappingName = $"SensorIntensities[{i}]",

        resultGrid.Columns.Add(new GridNumericColumn()
            HeaderText = "Statistical Error",
            MappingName = $"SensorStatisticalErrors[{i}]",

        StackedHeaderRow shr = new StackedHeaderRow();

        shr.StackedColumns.Add(new StackedColumn()
            ChildColumns = $"SensorIntensities[{i}],SensorStatisticalErrors[{i}]",
            HeaderText = viewModel.SensorNames.ElementAt(i),

Shai Ben-Gigi,

We have checked the reported issue with the provided details. The reported scenario is not an issue, the stacked header rows were added multiple times based on the Iteration that’s why it showed like the shared screenshot. In the provided code snippet, you are adding the new StackedHeaderRows for every StackedColums that caused the reported problem. You should add all the StackedColumns into one StackedHeaderRow shown in the below user guide documentation,
