C# 添加Excel表單控件(Form Controls)

在Excel中,添加的控件能夠和單元格關聯,咱們能夠操做控件來修改單元格的內容,在下面的文章中,將介紹在Excel中添加幾種不一樣的表單控件的方法,包括:html

  •  添加文本框(Textbox)
  •  單選按鈕(Radio button)
  •  複選框(Checkbox)
  •  組合框(combo Box)

使用工具

PS:下載安裝該組件後,注意在項目程序中添加引用Spire.Xls.dll(dll文件可在安裝路徑下的Bin文件夾中獲取),以下圖所示ide

代碼示例

【示例1】插入Excel表單控件

步驟1:建立工做表工具

//實例化一個Workbook類實例,並獲取第1個工做表
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];

//設置表格行高、列寬
sheet.Range["A1:F1"].ColumnWidth = 15F;
sheet.Range["A1:B12"].RowHeight = 20F;

步驟 2:插入文本框spa

//插入文本框控件,指定文本框位置、大小以及文本對齊方式
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;

步驟 3:插入單選按鈕code

//插入單選按鈕,指定單元格位置
sheet.Range["A3"].Text = "性別:";
IRadioButton radioButton = sheet.RadioButtons.Add(3, 2, 20, 80);
radioButton.CheckState = CheckState.Checked;
radioButton.Text = "";
radioButton = sheet.RadioButtons.Add(3, 3, 20, 80);
radioButton.Text = "";

步驟 4:插入複選框orm

//插入複選框並指定單元格位置
sheet.Range["A5"].Text = "所在行業:";
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 = "醫療";
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 = "其餘";            

步驟 5:插入組合框htm

//插入組合框,並指定單元格位置、大小
sheet["A7"].Text = "年齡(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"];

步驟 6:指定Combox的關聯單元格blog

sheet["A12"].Text = "表明人羣類別:";
comboBox.LinkedCell = sheet.Range["B12"];
comboBox.SelectedIndex = 1;

步驟 7:保存文檔文檔

workbook.SaveToFile("AddFormControls.xlsx", ExcelVersion.Version2010);

運行該項目程序,生成文件(可在項目文件夾bin>Debug下查看文檔)get

所有代碼:

using Spire.Xls;
using Spire.Xls.Core;
using System.Drawing;

namespace FormControls_XLS
{
    class Program
    {
        static void Main(string[] args)
        {
            //實例化一個Workbook類實例,並獲取第1個工做表
            Workbook workbook = new Workbook();
            Worksheet sheet = workbook.Worksheets[0];

            //設置表格行高、列寬
            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、大小以及文本對齊方式
            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;

            //插入單選按鈕,指定單元格位置
            sheet.Range["A3"].Text = "性別:";
            IRadioButton radioButton = sheet.RadioButtons.Add(3, 2, 20, 80);
            radioButton.CheckState = CheckState.Checked;
            radioButton.Text = "";
            radioButton = sheet.RadioButtons.Add(3, 3, 20, 80);
            radioButton.Text = "";

            //插入複選框並指定單元格位置
            sheet.Range["A5"].Text = "所在行業:";
            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 = "醫療";
            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 = "其餘";            
            
            //插入組合框,並指定單元格位置、大小
            sheet["A7"].Text = "年齡(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"];

            //指定組合框的關聯單元格
            sheet["A12"].Text = "表明人羣類別:";
            comboBox.LinkedCell = sheet.Range["B12"];
            comboBox.SelectedIndex = 1;

            //保存文檔
            workbook.SaveToFile("AddFormControls.xlsx", ExcelVersion.Version2010);
            System.Diagnostics.Process.Start("AddFormControls.xlsx");
        }
    }

【示例 2】 刪除Excel表單控件

 步驟 1:加載文檔,並獲取指定單元格

Workbook workbook = new Workbook();
workbook.LoadFromFile("test.xlsx");
Worksheet sheet = workbook.Worksheets[0];

步驟 2:刪除組合框

for (int i = 0; i < sheet.ComboBoxes.Count; i++)
{
    sheet.ComboBoxes[i].Remove();
}

步驟 3:保存文檔

workbook.SaveToFile("RemoveComboBoxes.xlsx", ExcelVersion.Version2010);

 

所有代碼:

using Spire.Xls;


namespace RemoveFormControl_XLS
{
    class Program
    {
        static void Main(string[] args)
        {
            //建立Workbook實例,加載Excel文檔
            Workbook workbook = new Workbook();
            workbook.LoadFromFile("test.xlsx");

            //獲取第一個工做表
            Worksheet sheet = workbook.Worksheets[0];

            //刪除工做表中全部的組合框
            for (int i = 0; i < sheet.ComboBoxes.Count; i++)
            {
                sheet.ComboBoxes[i].Remove();
            }

            //保存並打開文檔
            workbook.SaveToFile("RemoveComboBoxes.xlsx", ExcelVersion.Version2010);
            System.Diagnostics.Process.Start("RemoveComboBoxes.xlsx");
        }
    }
}
View Code

運行程序後,表格中相應的控件將被刪除。
