C# DataGrid 样式设置：字体大小、标题样式

DataGrid displayData = new DataGrid();
displayData.Name = 'displayData';
displayData.Margin = new Thickness(5);
displayData.CanUserAddRows = false;

Style cellStyle = new Style(typeof(DataGridCell));
Setter fontSizeSetter = new Setter(DataGridCell.FontSizeProperty, 18);
cellStyle.Setters.Add(fontSizeSetter);
displayData.CellStyle = cellStyle;

Style columnHeaderStyle = new Style(typeof(DataGridColumnHeader));
Setter columnHeaderFontSizeSetter = new Setter(DataGridColumnHeader.FontSizeProperty, 18);
Setter columnHeaderFontWeightSetter = new Setter(DataGridColumnHeader.FontWeightProperty, FontWeights.Black);
columnHeaderStyle.Setters.Add(columnHeaderFontSizeSetter);
columnHeaderStyle.Setters.Add(columnHeaderFontWeightSetter);
displayData.ColumnHeaderStyle = columnHeaderStyle;

Grid.SetRow(displayData, 2);
myGrid.Children.Add(displayData); // assuming myGrid is the name of your parent grid.

本示例展示了如何在C#中设置 DataGrid 的样式，包括调整单元格字体大小和标题字体大小、加粗等操作。你可以根据需要修改字体大小和样式属性。
