在Excel中,添加的控件可以和单元格关联,我们可以操作控件来修改单元格的内容,在下面的文章中,将介绍在Excel中添加几种不同的表单控件的方法,包括:
- 添加文本框(Textbox)
- 单选按钮(Radio button)
- 复选框(Checkbox)
- 组合框(combo Box)
使用工具
PS:下载安装该组件后,注意在项目程序中添加引用Spire.Xls.dll(dll文件可在安装路径下的Bin文件夹中获取),如下图所示
代码示例
【示例1】插入Excel表单控件
步骤1:创建工作表
//实例化一个Workbook类实例,并获取第1个工作表 Workbook workbook = new Workbook(); Worksheet sheet = workbook.Worksheets[0]; //设置表格行高、列宽 sheet.Range["A1:F1"].ColumnWidth = 15F; sheet.Range["A1:B12"].RowHeight = 20F;
步骤 2:插入文本框
//插入文本框控件,指定文本框位置、大小以及文本对齐方式 sheet.Range["A1"].Text = "姓名:"; ITextBoxShape textBox = sheet.TextBoxes.AddTextBox(1, 2, 25, 110); textBox.Text = "John"; textBox.HAlignment = CommentHAlignType.Center; textBox.VAlignment = CommentVAlignType.Center;
步骤 3:插入单选按钮
//插入单选按钮,指定单元格位置 sheet.Range["A3"].Text = "性别:"; IRadioButton radioButton = sheet.RadioButtons.Add(3, 2, 20, 80); radioButton.CheckState = CheckState.Checked; radioButton.Text = "女"; radioButton = sheet.RadioButtons.Add(3, 3, 20, 80); radioButton.Text = "男";
步骤 4:插入复选框
//插入复选框并指定单元格位置 sheet.Range["A5"].Text = "所在行业:"; ICheckBox checkBox = sheet.CheckBoxes.AddCheckBox(5, 2, 18, 65); checkBox.CheckState = CheckState.Checked; checkBox.Text = "教育"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 3, 18, 65); checkBox.Text = "医疗"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 4, 18, 65); checkBox.Text = "IT"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 5, 18, 65); checkBox.Text = "零售"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 6, 18, 65); checkBox.Text = "其他";
步骤 5:插入组合框
//插入组合框,并指定单元格位置、大小 sheet["A7"].Text = "年龄(段):"; sheet["A8"].Text = "<18"; sheet["A9"].Text = "18<Y<30"; sheet["A10"].Text = "30<Y<50"; IComboBoxShape comboBox = sheet.ComboBoxes.AddComboBox(7, 2, 23, 100); comboBox.ListFillRange = sheet["A8:A10"];
步骤 6:指定Combox的关联单元格
sheet["A12"].Text = "代表人群类别:"; comboBox.LinkedCell = sheet.Range["B12"]; comboBox.SelectedIndex = 1;
步骤 7:保存文档
workbook.SaveToFile("AddFormControls.xlsx", ExcelVersion.Version2010);
运行该项目程序,生成文件(可在项目文件夹bin>Debug下查看文档)

using Spire.Xls; using Spire.Xls.Core; using System.Drawing; namespace FormControls_XLS { class Program { static void Main(string[] args) { //实例化一个Workbook类实例,并获取第1个工作表 Workbook workbook = new Workbook(); Worksheet sheet = workbook.Worksheets[0]; //设置表格行高、列宽 sheet.Range["A1:F1"].ColumnWidth = 15F; sheet.Range["A1:B12"].RowHeight = 20F; //插入文本框控件,指定文本框位置、大小以及文本对齐方式 sheet.Range["A1"].Text = "姓名:"; ITextBoxShape textBox = sheet.TextBoxes.AddTextBox(1, 2, 25, 110); textBox.Text = "John"; textBox.HAlignment = CommentHAlignType.Center; textBox.VAlignment = CommentVAlignType.Center; //插入单选按钮,指定单元格位置 sheet.Range["A3"].Text = "性别:"; IRadioButton radioButton = sheet.RadioButtons.Add(3, 2, 20, 80); radioButton.CheckState = CheckState.Checked; radioButton.Text = "女"; radioButton = sheet.RadioButtons.Add(3, 3, 20, 80); radioButton.Text = "男"; //插入复选框并指定单元格位置 sheet.Range["A5"].Text = "所在行业:"; ICheckBox checkBox = sheet.CheckBoxes.AddCheckBox(5, 2, 18, 65); checkBox.CheckState = CheckState.Checked; checkBox.Text = "教育"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 3, 18, 65); checkBox.Text = "医疗"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 4, 18, 65); checkBox.Text = "IT"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 5, 18, 65); checkBox.Text = "零售"; checkBox = sheet.CheckBoxes.AddCheckBox(5, 6, 18, 65); checkBox.Text = "其他"; //插入组合框,并指定单元格位置、大小 sheet["A7"].Text = "年龄(段):"; sheet["A8"].Text = "<18"; sheet["A9"].Text = "18<Y<30"; sheet["A10"].Text = "30<Y<50"; IComboBoxShape comboBox = sheet.ComboBoxes.AddComboBox(7, 2, 23, 100); comboBox.ListFillRange = sheet["A8:A10"]; //指定组合框的关联单元格 sheet["A12"].Text = "代表人群类别:"; comboBox.LinkedCell = sheet.Range["B12"]; comboBox.SelectedIndex = 1; //保存文档 workbook.SaveToFile("AddFormControls.xlsx", ExcelVersion.Version2010); System.Diagnostics.Process.Start("AddFormControls.xlsx"); } } }
【示例 2】 删除Excel表单控件
步骤 1:加载文档,并获取指定单元格
Workbook workbook = new Workbook(); workbook.LoadFromFile("test.xlsx"); Worksheet sheet = workbook.Worksheets[0];
步骤 2:删除组合框
for (int i = 0; i < sheet.ComboBoxes.Count; i++) { sheet.ComboBoxes[i].Remove(); }
步骤 3:保存文档
workbook.SaveToFile("RemoveComboBoxes.xlsx", ExcelVersion.Version2010);
全部代码:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
using Spire.Xls; namespace RemoveFormControl_XLS { class Program { static void Main(string[] args) { //创建Workbook实例,加载Excel文档 Workbook workbook = new Workbook(); workbook.LoadFromFile("test.xlsx"); //获取第一个工作表 Worksheet sheet = workbook.Worksheets[0]; //删除工作表中所有的组合框 for (int i = 0; i < sheet.ComboBoxes.Count; i++) { sheet.ComboBoxes[i].Remove(); } //保存并打开文档 workbook.SaveToFile("RemoveComboBoxes.xlsx", ExcelVersion.Version2010); System.Diagnostics.Process.Start("RemoveComboBoxes.xlsx"); } } }
运行程序后,表格中相应的控件将被删除。
