问题描述
当我选中gridview中的复选框并将其导出到所选记录的CSV文件时，在CSV文件中，TRUE会出现在复选框列中。我想从生成的CSV文件中删除它，只显示数据，而不是复选框列。请帮我解决问题
When I check the checkboxes in gridview and export it to CSV file for the selected records,in the CSV file 'TRUE' comes in the checkbox column. I want to remove this from the generated CSV file and display only the data,not the checkbox column. Kindly help me solve the issue

推荐答案
在Form1的构造函数中，在索引0处插入 checkBoxColumn 所以解决方案很简单：在你的for循环中你编写标题，然后行从索引1而不是0开始。
In the constructor of Form1 you insert checkBoxColumn at index 0. So the solution is simple: In your for-loops where you write the headers and then the rows start at index 1 instead of 0.
