How to remove text decoration in DataGridTemplateColumn?

[LejlaBrkic123]

I am using DataGridTemplateColumn for autogenerated columns in datagrid, and creting them using framework elements. How to remove underline in that way created columns.
I have tried by adding a new style and putting textdecoration property as null but my other thing defined by defulta style are then messed up.

Hi @LejlaBrkic123 are you able to share some of your code demonstrating what you are doing?

[LejlaBrkic123]

yes, for example I am using this method

public DataGridTemplateColumn CreateDataGridTextBoxTemplateColumn(string propertyName, List<DataTableColumnDefinition> dataTableColumnDefinitions, DataTable dataTable)
        {
            try
            {
                var columnDefinition = dataTableColumnDefinitions.Where(reg => reg.Name == propertyName 
                                                && reg.TargetDataTable == dataTable && reg.DataType == typeof(string) && !reg.IsReadOnly).ToList();
                if (columnDefinition == null || columnDefinition?.Count == 0)
                {
                    return null;
                }
            }
            catch (InvalidOperationException)
            {
                //Either not registered as a dropdown column or not a registered column at all, or not in DisplayedDataTable
                //This will cause UI to default the dataGridColumn to Text Column
                return null;
            }

            var dataGridTemplateColumn = new DataGridTemplateColumn { Header = propertyName };
            var cellTemplate = new DataTemplate();
            var textBoxFactory = new FrameworkElementFactory(typeof(TextBox));
            textBoxFactory.SetBinding(TextBox.TextProperty,
                new Binding(propertyName)
                {
                    Mode = BindingMode.TwoWay,
                    UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged
                });
            cellTemplate.VisualTree = textBoxFactory;
            dataGridTemplateColumn.CellTemplate = cellTemplate;

            return dataGridTemplateColumn;
        }

and also on the similiar way the column with combobox.
I am using styling for datagrid and some properties are applied correctly and if I add in previous method new styling with no underline textbox, I got that but my other properties defined with styling are not correct as font, outline border and so on.
